It's time to structure my wanderings and face denial about the special problems of dangers of living with partial eyesight. This post starts a simple framework for analyzing risks and defining responses. Sighted readers may become aware of hassles and barriers presented to Vision Losers who may learn a few tricks from my experience.
Life is looking especially risky right now: financial follies, pirate attacks, natural disasters, ordinary independent activities, ... A Vision Loser needs special precautions, planning, and constant vigilance. So, here I go trying to assemble needed information in a format I can use without freaking myself back into a stupor of denial.
"Live annually on 4% of your assets".Another rule, one I obey, that could have saved $trillions is like:
Housing payment not to exceed 1/3 Income.Such rules help focus on the important trade-offs of what we can and cannot do sensibly rather than get bogged down in complex models and data we can't fully understand or properly control. If we can abstract an effective rule from a mass of details, then we might be able to refresh the rule from time to time to ask what changes in the details materially affect the rule and what adjustments can cover these changes. We can also use generally accepted rules to validate and simplify our models. This is especially important for the partially sighted since extra work goes into interpreting what can be seen and considerable guess work into what's out there unseen.
I need comparable safety rules to internalize, realizing their exceptions and uncertainty. Old rules don't work too well, like "Look both ways before crossing the street". also listen, but what about silent cars. Or "turn on CNN for weather information" if I can't read the scrolling banners.
When I taught software engineering, the sections on project management always emphasized the need for Risk Management in the context of "why 90% of software projects fail". This subject matter made the basis for a good teamwork lab exercise: prioritize the risks for a start up project. I dubbed this hypothetical project Pizza Central, a web site to compare local pizza deals and place orders, with forums for pizza lovers. Since all students are domain experts on both pizza deliveries and web site use, they could rapidly fill out a given template. Comparing results always found a wide divergence of risks among teams, some focused on website outage, others on interfaces, some on software platforms. So, one lesson conveyed among teams was "oops, we forgot about that". My take-away for them was that this valuable exercise was easy enough to do but required assigned responsibilities for mitigating risks, tracking risk indicators, and sometimes unthinkable actions, like project cancellation.
I am about to try a bit of this medicine on myself now. Risk is a complicated subject, see Wikipedia. I'll use the term as "occurrence of a harmful event" in the context of a project or activity. The goal is to mitigate both the occurrences and effects of these nasty events. But we also need indicators to tell when an event is ongoing or has happened. Since mitigation has a cost of response both to prevent and recover from events, it helps to have prioritization of events by likelihood and severity. So, envision a spreadsheet with event names, ratings for likelihood, severity, and costs, perhaps with a formula to rank importance. Associated with these events are lists of indicators, proposed mitigation actions with estimated costs. This table becomes part of a project plan with assigned actions for mitigations and risk tracking awareness across team members as a regular agenda item at project meetings..
I will follow this through on the example of my daily workout walk. I do not use my white cane because I feel safe enough, but really, is this a good tradeoff? Without the cane, I can walk briskly, arms swinging, enjoying shadows, tree outlines, and the calls of quail in the brush. The long white cane pushes my attention into the pavement, responding to minor bumps and cracks my strides ignore, and there's even a rhythm to the pavement that adjusts my pace to a safe sensation. I would not think of walking without my guiding long white cane on a street crowded with consumers or tourists but this walk covers familiar terrain at a time frequented by other recreational walkers. This situation is a trade-off unique to the partially sighted, who only themselves can know what they can safely see and do, living with the inevitable mistakes and mishaps of the physical world.
Here are a few events, with occasional ratings on a 1-10 scale. For this application, I feel it's more important to ask the right questions, albeit some silly, to surface my underlying concerns and motivate actions.
Background:
As I lost vision due to myopic degeneration, My computer use modes switched to audio. I was swept into a world of rich information resources and innovative mobile devices that rejuvenated my personal interests in computing. Learning to use assistive technology while studying the practices of accessibility motivated me to write my personal experiences in the "As Your world changes" blog. I seek to create a framework of concepts that integrate the lessons and techniques of what is customarily considered deficient abilities into the mainstream of computing for the betterment of all based on the "curb cuts" principle. The physical world 'curb cut' analogy flows over into computing in the following ways.
So-called assistive technologies today expand the way computers are used in an essential sense, incidently overcoming some human deficiencies. Better designed ways of using only a keyboard without a mouse offers power shortcuts to everybody. Consistent displays in high contrast modes offer more relaxing viewing that cut the glare that causes natural photosensitivity and mental stress across a wide range of eyesight conditions. Text to speech from screen readers offers eyes-free reading of long web pages for audio adapted multi-tasking individuals while also providing GUI interactions for the visually impaired. Digital talking books and newspapers will eventually be available commodities for sighted readers as they have been for years to qualified print-disabled individuals.
Because there is now an artificial line that views such technologies ass assistive rather than normal options, products are designed for or against certain users. Emphasis on the GUI has restricted advances in speech-enabled applications with the potential for many new innovations and wider markets. Studies on the plasticity of the brain suggest that more satisfying and productive use of computers flows from integration of visual, audio, and tactile modes of processing information.
Erasing the artificial lines and labels of assistive as separate and remedial technology offers a chance to revitalize the visual dominated modes of computing that no longer apply within a marketplace of diverse hardware and software components. Integration of so-called assistive technologies and accessibility practices will show the flaws of products developed only for an assumed fully enabled user.
Accessibility and usability are well defined if underused principles of product quality. The 'curb cuts' principle suggests that a defect with respect to these qualities is in a poorly understood or unexplored area of a design. Often a problem that presents only a little trouble for the expected "normal" user is a major hassle or show stopper for those with certain physical or cognitive deficiencies. However, those flaws compound and often invisibly reduce productivity for all users. Increasingly, these deficiencies arise from ambient environmental conditions such as glare, noise, and potential damage to users or devices.
Moreover, these problems may also indicate major flaws related to the integrity of a design and long term maintainability of the product. An example is the omission of Headings on an HTML page that makes it difficult to find content and navigation divisions with a screen reader. This flaw usually reveals an underlying lack of clarity about the purpose and structure of the website and page. Complexity and difficult usability often arise from missing and muddled use cases. Attitudes opposing checklist standards often lead to perpetuating poor practices such as the silly link label "click here".
The 'curb cuts' principle leads toward a theory of design that requires remedy of accessibility problems not as a kindness to users nor to meet a governmental regulation but rather to force exploration through difficult or novel parts of the design terrain. The paradigm of "universal design" demands attention to principles that should influence requirements, choice of technical frameworks, and attention to different aesthetics and other qualities. For example, design principles may address where responsibilities lie for speech information to a user, thus questioning whether alternative architectures should be considered. Applying this principle early and thoroughly potentially removes many warts of the product that now require clumsy and expensive accessibility grafts or do-overs.
Just as the design patterns movement grew from the architectural interests of Christopher Alexander, attention to universal design should help mature the fields for software and hardware. The "curb cuts" principle motivates designers to think beyond the trim looking curb to consider the functionality to really serve and attract ever more populations of end users.
Computer professionals are often shocked when they see how difficult their products are to use, reaching levels of excruciating pain for persons with disabilities. Professional pride is a motivating factor for many individuals attracted to the computing field, e.g. women and games that truly enhance their views of human potential and relationships.
The market motive is obvious with many millions of persons with disabilities to be included in the mainstream rather than being totally excluded or segregated into the higher priced rehabilitation industrial complex. Especially as the U.S. population ages, the social services are simply not there to smooth their transition and maintain their purchasing influence. Services of all kinds work more efficiently with fewer exceptions due to individuals requiring special processing.
There are so many genuinely innovative products designed by the blind, e.g. a screenless Linux PDA that rivals the Kindle with book, news, and RSS access and reading. An international open source project driven by energetic Australians is producing a free screen reader for global use with synthetic voices in dozens of languages. A standard camera-phone can now read menus and transactions items, even currency. A $5 audio device is being designed to bridge the literacy gap in impoverished societies. some people are also drawn into a futuristic world of open source hardware for designing gadgets that will speak what they are doing, how to use them, and their location, orientation, and other physical properties.
for many The social good of enabling equal access to computing is an attractor to a field renowned for nerds and greed. Social entrepreneurs offer an expansive sense of opening doors to not only education and entertainment but also employment, that now stands around 20% for disabled persons. Many innovative nonprofit organizations take advantage of copyright exemptions building libraries and technology aids for alternatives to print and traditional reading.
The computing curb cuts principle can motivate professionals, services, and end users to achieve the potential beauty and magic of computing in everyday life, globally, and for everybody who will eventually make the transition into some form of sensory, motor, or mental deficiency. But, first, mainstream computing must open its knowledge and career paths to encompass the visionaries and advances now segregated. All too often persons with disabilities are more advanced, diversified, and skill full in ways that could benefit not yet disabled people.
The "curb cuts" metaphor offers a compelling and, well, concrete way of motivating new attitudes toward computing. Walk down any American street and the reminders are at each intersection. Every computer professional will be on the hook to deliver universally usable products, not wait three years as happened with iTunes and only under legal threats, as may come soon with Google's Chrome and Google Book Search or the Amazon and Target websites. Failing to universally design a computing product is as much a social menace as a missing or poorly designed concrete curb. The computing curb cut provides a metaphor to tell the public about new ways for improving their lives and the value of innovations that will follow from obliterating the artificial border with accessibility. <img src="http://www.ada.gov/images/flaredramp1.jpg" ALT="curb cut schematic from ADA.gov"
September is a reminder month for topics that challenge a Vision Loser. September 8 was International Literacy day and the 26 begins Banned books week. This post describes a technology project that forced me to think about how impoverished, illiterate people survive, and a creative low cost way to help them. I also face a personal decline in literacy without a replacement for reading pie charts. I chastise myself for accepting a sloppy literacy in the language of keyboards, menus, and application interface tasks. I Try to overcome vision limitations by seeking simple, powerful, memorable formulas using numeracy to conquer reading limitations. One of those formula leads me to an example of dubious information literacy, a quotation by Einstein. In passing, I pick up a new term 'trans-literacy' to describe the phenomena of literacy across media, including Braille. And, without getting too political, my book club discussions help me nail down some fundamental questions of belief systems that counter banning premises.
Here's an example of vision literacy issues. If I cannot find the line to sign a receipt for a prescription, that is simply a vision deficiency that requires trust of the pharmacy that I am signing appropriately. I could overcome this deficiency using the KNFB reader but it's not worth the effort. I have the literacy to find the charge entry on the bank system website If a correction is required. the phone number should be associated with the transaction for Kmart pharmacy but I may have trouble finding the local number. these are all variations of the problems of getting the symbols from a jumble of data into my brain, requiring hard work but doable. A different form of literacy occurs at the end of the year when the credit card company sends me a summary of cumulative transactions. Perhaps tabularized or represented in charts. I no longer have the ability to drill down or read out from a pie chart to find the percentage for annual medical costs. This complicates my planning for retirement expense estimation. Literacy has been lost, I hope only temporarily. I can only translate those external symbols into a mental representation by mastering intermediate technologies, e.g. transforming printed characters into sounds through synthetic speech.
Absolutely no vision is required to use the Talking Book Device. From the beginning, we've wanted the device to work without the need for vision. There's no display -- all system indicators and prompts are aurally. The buttons are embossed. The device has non-visual indicator, a green and red LED, but that indicator is redundant the aural information.Whoopee! My accessibility dreams come forth. Like how my late father enjoyed the boxes of remainder books I brought him, as well as his requests, in his assisted living location. Imagine a device that could be rapidly refilled with human or synthetic spoken books from a kiosk or a peer device in the hallway. The might have encouraged more book clubbing among readers with vast life experience. And I'll bet he would have been multitasking book reading, recording, TV watching, memoir writing, and I hate to think what else. Conquering file transfer problems and exploiting digital content would have meant so much a decade ago, even more to baby boomers and beyond comfortable in the audio realm but limited in sensory apparatus. I wonder also if convincing cost breakthroughs in self-voiced devices can help alleviate some health care costs.
The LiteraryBridge web site accessibility problems are due to ISP provided templates that also trapped me once into painfully scraping excess HTML off my own web content. But the message is well amplified by recent news articles and podcasts. I even made it all the way through checkout on the donation form, which often lead me to cursing the insensitive form makers. I found a wonderful picture of illiteracy and poverty that might soon be changed by well designed low cost digital equipment, combined with localized information networks, supported by donations and volunteer effort. Watch this social entrepreneurial story unfold.
This got me thinking how reading charts is a form of literacy, often called numeracy, or quantitative literacy. I've see these charts in middle school textbooks but I suspect many adults are chart illiterate. Not me. Having programmed with a chart tools and hyperlinks I understand well how raw data can be converted into alternative graphic forms to facilitate rapid assimilation of relative values in a data set. In a hypertext world, those charts can drive navigation to web data linked via image maps. But now I can neither visually process the chart down to the labels and numeric values nor infer a mental representation of the data in the table. I am going to be very grumpy at age 90 in 2033 if I run out of money and suspect I chose the wrong asset allocation.
There are alternatives to tabular and graphic printed formats. Tactile maps can be created but these require external devices and reading abilities comparable to Braille. I am currently Braille illiterate, a symbol system and sensory skills usually not offered to or self-learned by retired Vision Losers. Another option is software like Chart Explainer that creates textual representations from data sets and chart presentations.
A third possibility I would favor but have not found is a way to interact by audio and keyboard with the basic data set. Just as an audio player supports short steps, longer jumps and extreme moves forward and backward, I would like to use my arrow keys to explore data arranged in bar, pie, or other chart format I remember so well. Comparison data could be announced using other keys. In a few minutes, with the small number of data items in this situation, I believe I could absorb the content sufficient to decide whether I like the allocation. For example, I think I would have a gut reaction to finding abnormally large real estate funds or negligible international fund allocations. More so than struggling to magnify pie slices or hear jumbled numbers across a row, the effect of finger actions and controlling of interactions would absorb and stimulate my brain to formulate its own model of the data. Whether that model was accurate is another matter.
Are there versions of Excel or other quantitative tools that support non-visual interaction? I'd really like to try these out. I certainly expect a Java or DOJO widget could provide me the combination of interaction and audio information. I wonder if sighted people might also benefit by bringing together their tactile, auditory, visual reasoning capabilities rather than staring at non-interactive charts.
As I become a more experienced Vision Loser, seeking always independence, I become more frustrated with current word processing. Let's see, analysts generate boilerplate and formulas for allocations, produce 30 page documents, print and bind these, send them to me, and I scan them using Kurzweil 1000. data about my very own money and these analysts' projections are all too much imprisoned in documents. Using PDF is not much better than printed documents unless attention is paid to propagating data sets through tags rather than pixels..
Applying to retirement planning, for all the analysis and allocation mumbo-jumbo, what I really need to know is some rule that I can withdraw something like 5% of net worth, adjusted quarterly, and live to that awful age of 95. Also can I assume that the models such as 1/3 invested in annuities is an all around good bet based on last 50 years and a dose of reasoning.
This brings me back to those simple formulae that provide guidance. I ask my youngsters, if you were born in the, say, 75% of the world that holds different beliefs, e.g. in the Middle east rather than America, would you be able to explain and justify their belief system? Wouldn't your current beliefs differ by culture you are born into? consider the institutional structures encompassing those belief system, if you questioned, say 10% of those beliefs, could you remain in good standing in the institution? It's wonderful that the Banned Book Week tradition raises these questions each year and that book clubs, like ours for AAUW members, reinforce the discussion and that my favorite library Bookshare even seeks out banned books for Vision Losers to read.
I decided that since the Help America vote act had encumbered quite a view million $$$ for fancy electronic equipment with accessible extension, I would take my chances to vote as independently as possible this round. Here's the story of early voting in an Arizona primary. Vision Losers might use this experience to evaluate their own voting options. Other citizens and technologists will learn how electronic voting works for one tech savvy Vision Loser.
First, let me say that, as an informed computer scientist, I do not for one nanosecond believe the odds are very high that my voting precinct actually got a correct tally of votes, including mine. I voted on a setup from the infamous Diebold, now renamed to Premiere Election, Systems. There's just no way any independent assurance organization can reasonably test a black box version of software and hardware, let alone all the combinations of diverse local ballot designs multiple configurations of the setup, and inevitable versions of evolving software. And that's not worrying about human error by voting board personnel, malicious people, or silly policies like Ohio's sleep-over procedures. Business ideology has trumped common sense democracy for Americans, unlike Australia and other countries that adopt an open approach.
Nevertheless, I wanted my independence and to force myself through the best possible preparation. A few months ago, I paid a visit to the Yavapai county recorder's Office for a personal trial on a mock ballot so I would be familiar with the equipment. I was reasonably impressed with the audio system, very enthusiastic about the personnel who welcomed the opportunity to try out their audio setup, and comfortable about working the equipment rather than asking someone to read and mark my ballot. I knew the actual voting would be slow and that I needed to do my homework on candidates and races so I could concentrate on the voting act itself.
I was pleased to find a nice little primary coming up in September with early voting several weeks ahead. One primary race is especially important in Arizona district No. 1, to replace rep. Rick Renzi who was indicted on 35 counts of fraud and other bad stuff. With a senator as presumptive Presidential candidate and a 40% voting record, Poor representation of this region for months especially annoys me as economic and social policies have consequences I had not foreseen as I grapple with my own rehabilitation and my family's future. Both major parties had a good slate of 4 or 5 candidates with experience relative to a highly diverse region of Indian reservations, small cities, and lots of open space.
I made my choice of party and candidate for Congress and began to look for the other races of interest. There were few contests so I assumed the ballot would be a piece of cake. Actually, I had some trouble figuring out the full set of races. I used VoteSmart, the AZ clean elections site, the county listing of candidates, Arizona Republic and Daily Courier candidate blurbs, even Wikipedia. A sample ballot arrived just before my trip to the polling place, but my reader and I were confused about a long list of write-in lines.
So, as much prepared as I could be, I entered the county office lobby and asked to vote using the audio system. I think I was the first to request this as a flurry of calls upstairs quickly produced an access card to a screen protected by side blinders and the headset and keypad I had used in my previous experiment. Oh, and most important was a chair.
To summarize the audio voting process, you click the appropriate numbered buttons to advance through races, making and confirming choices while hearing the race titles, constraints and candidate names through headphones. There is nothing visual happening. I listened to the instructions and tried to adjust the volume to match both a synthetic voice announcement of races and human recorded reading of candidate names, using female voices. Occasionally, other customers and voters in a noisy lobby overcame the headset ear pads. The input device was a simple phone keypad with larger sized keys, comfortably held in my lap.
I moved quickly through my choice for the congressional and legislative races. Then things became unfamiliar with more races for county offices and state supreme Court seats all with only a write-in option. Not having any choice, I kept hitting 6 to next race, 9 to confirm my under-voting for continuation to next race. At one point , my attention drifted and I seemed to be in a loop of hitting next without actually having races announce, maybe between district, county, and state races.
After a while I got bored and tried an actual write-in, "gump" sounded good at the moment, and was easy to type although tedious to spell and confirm. Then I got serious and canceled out of write-in. In successive races for supreme court seats, the synthetic voice seemed to be getting faster, and very high pitched. Now, I can listen to really fast voices on my reading appliances. But by the end of what seemed like 50 races, I couldn't understand the voice. Nor could I remember how to get the main menu or adjust voices. I was stuck, hoping the end would come before I fell asleep at the keypad. Finally, the printer attached to the side clattered and the voice trailed off into oblivion. My nearly trance state lifted and I called for the attendant to complete the session.
Had I actually accomplished my voting goals? I think so as the early races that mattered seemed to be OK, but since I lost control in the middle and was pretty confused toward the end, I can only hope nothing invalidated those early race clicks. This whole process took about 30 minutes, long enough I had to wake up my driver to leave . I reported my troubles to the poll assistants but left unsure we understood the cause of my loop and voice speed-up. My guess is that the speed up started when I hit the relevant key during my write-in fumbling and the modes got confused as I skipped through further write-in choices.
I had hoped this experience could be recommended to others, but, alas, I fear those less adept at computer interactions might not find the humor in the loop and could freak out with babbling voices. I will vote again this way in November but next time pay lots more attention to the exit, speed, and volume options. Everybody has a limit to attention and energy to put into this voting exercise. Half an hour for a handful of races and an enormous number of later vacuous choices is a dubious way of getting the job done.
Another lesson for next time is to seriously invest more effort into learning about picking candidates. I hope to find more help from the SunSounds state audio assistance radio system or locate better candidate description materials. For example, the AZ Clean elections brochure that arrived in the mail was organized by race, then district, then party, then candidate which was beyond my patience to scan or anybody else's willingness to read to me only the district No. 1 choices on pages 4, 39, and so on. Perhaps voting early beats preparation of more candidate comparisons and recommendations from organizations like league of women voters. Perhaps my "domain knowledge" of elections and state offices made my Google and dog pile searches susceptible to donate Now organizations. Certainly, I have not yet found a good source of advice directed to people like me voting blind for the first time. What I really want is a web page duplicating the ballot, divided into levels of government, with attached very short bios and links to longer histories, position statements, and reputable sources of candidate comparisons. The HTML and hypertext structuring are important as PDF is hard to use by audio and often loses the content structure when converted to a text stream. It might also be nice to have a candidate-a-day RSS feed to make the information more digestible in smaller chunks.
I would recommend to others considering using an audio or visually assisted voting workstation to request a trial. Yes, that means taking up time from election board workers, but I found them helpful, friendly, and interested in feedback. Anybody who can handle a bank ATM via audio should be ready to try out the system. However, someone with hearing problems might not be able to adjust the equipment to their needs in a noisy environment. The long-time blind who readily adapt to new devices should appreciate the new-found independence. However, new Vision Losers are faced with lot of work to master both the information gathering and the audio assisted voting process.
My biggest warning is the time commitment to survive the rigors of a long ballot. Had I wanted to actually write in a lot of names, I would have been there until closing time. With so few voters like me, there seems little data to accumulate experience for a warning label, but this is a practical constraint. Voters need to know how much time to ask of their drivers. With more voters using the assistive workstation, there would be a long wait just to get your chance. I suppose I could have asked for assistance during my loops and voice accelerations, but I just wanted to get out of write-in hell. Far more instructional time could be required for first time users of the audio assistance, especially if the equipment balks at start up or printing. And, what happens if a voter gives up during a voting session or nearly goes into a trance, as happened to me? Of course, there are other disabilities more complex than vision, such as strength and mobility, for using different input devices.
Getting a bit more technical, in my earlier visit for a trial, we discussed the need for a simulator for voter training using the audible equipment. I'd appreciate knowing if this exists anywhere. Since the user interaction is by phone keypad, a simulator with a mock ballot, as in my trial, could service widespread people if they knew the voting system designated for them. This could be done by phone or be a downloaded or web 2.0 app, something even I could write if I knew the rules. I could have called up and learned the instructions in the quiet of my home, memorized my way out when I hit a snag, and also reported problems back to the ballot designers and equipment vendors. Had I known about the write-in race survivor test, I'm not sure I would have followed through an actual vote. Those suffering from synthetic voice shock could at least determine whether they wanted to try to and were able to interpret the race announcements and instructions.
While the overall interaction of voting with only audio is really pretty easy, clearly the keypad needs a separate HELP key and RESTORE DEFAULTS action. Maybe these were available, but I was so deep into figuring out how to reach the end of the ballot, I was not interested in finding the escape button. More seriously, as a software testing expert and veteran system breaker, I really would like to replicate my experiences with the next-race loop and accelerating voice problems. It would be too irreverent and silly for a 65 year old lady to whiz around a county office building crowing that I'd broken the system, lookee, the computer is in a really bad state. No, I really appreciated the professionalism and help of the voting staff, but, well, I think I did break something and wish it could be reported and corrected.
So, why don't I, a formerly reputable software professional try to do more? Well, first, with only two years of legal blindness I am still a learner in the assistive technology world. But more seriously, getting on my high horse, this whole system is an affront to U.S. citizenry. In my previous post, I equated electronic voting with two mixed metaphors, a "moon shot for democracy" and "extreme voting", like a sporting challenge.
Just as sputnik shocked the U.S. into action for education in science, just as a catastrophe on the moon in 1969 would have undermined U.S. Self-confidence, just as the later space shuttles failures signaled a decline in space travel prowess, a definitive failure in our voting system undermines our feeling of living in a democracy. Yet, there is every sign that our voting system continues to be bungled, in the names of fancier technology and free enterprise. In my mind, the quest for a technological solution is a doable, long term project but only if committed to the technologists with expertise and freedom to question the safety of every step in the process, test each component down to its core against its specifications, simulate to exhaustion, and finally rely on combined community acceptance of safety to launch. In many ways, a rocket system is easier to design because it works with and against the continuous laws of physics, whereas a voting system works on discrete math and with and against the laws of human capabilities and differences. The security quality of human interactions with system is another dimension of complexity, but the bottom line is that voting systems cannot be black box. Discrete systems must be subjected to inductive reasoning applied to the code, hardware, user scenarios, with a huge dose of version control. Experimental software engineering has established the efficacy of software inspection, especially performed early and often using multiple viewpoints from varieties of expertise. Asking a weak testing regime to accept the assurance of vendors of proprietary systems, even against clear signs of fallibility, is like delivering a rocket to the pad, asking the astronauts to jump on, and not telling mission control how the rocket will behave.
My other metaphor of extreme voting is based on both user and developer experience. it is a lot to ask voting equipment vendors to produce extensions to service all ranges of human differences, including those considered disabilities. I was amazed the keypad and audio system worked as well as it did. Indeed, I might ask why spend all that money on fancy visual interfaces when audio will do, except for hearing impaired people. Users like me are forced into extreme and unknown conditions like long ballots read by unfamiliar voices marked by never before touched keypads. Please accept my invitation to use a bank ATM by audio to get a feeling for this experience. My current ATM transaction time is about a minute by knowing the exact sequence of key clicks, but at first I had little idea of the menu structures or the confirmation, cancellation, and selection instructions held in mind. Voting by audio is a similar experience.
To sum up, even though I had prepared myself well, I fell into a mess of write-in races which cause me to either mishandle the keypad input or to find an actual flaw in the system. In either case, the unpredictability of the long ballot and time required to work through it present, not insurmountable, but discomfiting conditions of voting independently. But I survived, and will continue to vote this way in the big election in November. I will also work hard in perhaps better information conditions to identify the races and candidates where I really care about my vote. I certainly do not want to leave wondering if I have voted for the right guy.
As I communicate with other persons with progressive vision loss, I often sense a quite negative reaction to synthetic, or so-called 'robotic', voices that enable reading digital materials and interfacing with computers. Indeed, that's how I felt a few years ago. Let's call this reaction "synthetic voice shock" as in:
Synthetic voice reactions appear to criss-cross many so-called divides: digital, generational, disability, and developer. The free WebAnywhere is the latest example with a robotic voice that must be overcome in order to gain the possible benefits of its wide dissemination. Other examples are talking ATM centers and accessible audio for voting machines. The NVDA installation and default voice can repel even sighted individuals who could benefit from a free screen reader as a web page accessibility checker or a way to learn about the audio assistive mode. Bookshare illustrates book reading potential by a robotic, rather than natural, voice. Developers of these tools seen the synthetic voice as a means to gain the benefits of their tools while users not accustomed to speech-enabled hardware and software run the other way at the unfriendliness and additional stress of learning an auditory rather than visual sensory practice.
This is especially unfortunate when people losing vision may turn to magnifiers that can only improve spot reading, when extra hours and energy are spent twiddling fonts then working line by line through displayed text, when mobile devices are not explored, when pleasures of book reading and quality of information from news are reduced.
I would like to turn this posting into messages directed at developers, Vision Losers, caretakers, and rehab personnel.
The robotic voice you encounter with screen readers is used because it is fast and flexible and widely accepted by the blind community. But there do exist better natural voices that can be used for reading books, news, and much more. While these voices seem initially offensive, synthetic voices are actually one of the great wonders of technology by opening the audio world to the blind and gradually becoming common in telephony and help desks.
As one with Myopic Macular Degeneration forced to break away from visual dependency and embrace audio information, I testify it takes a little patience and self-training and then you hear past these voices and your brain naturally absorbs the underlying content. Of course, desperation from print disability is a great motivator! Once overcoming the resistance to synthetic voices, a whole new world of spoken content becomes available using innovative devices sold primarily to younger generations of educated blind persons. Freed of the struggle to read and write using defective eyesight, there is enormous power to absorb an unbelievable amount of high quality materials. As a technologist myself, I made this passage quickly and really enjoyed the learning challenge, which has made me into an evangelist for the audio world of assistive technology.
If you have low vision training available, ask about learning to listen through synthetic speech. For the rest of our networked lives, synthetic voices may be as important as eccentric viewing and using contrast to manage objects.
So, when you encounter one of these voices, maybe think of them as another rite of passage to remain fully engaged with the world. Also, please consider how we can help others with partial sight. With innovations from web anywhere and free screen readers, like NVDA, there could be many more low cost speaking devices available world wide.
Do not expect that all users of your technology will be converts from within the visually impaired communities familiar with TTS. Provide a voice tuned in pitch and speed and simplicity for starters to achieve the necessary intelligibility and sufficient pleasantness. Suggest that better voices are also available and show how to achieve their use.
It's tough to spent development effort on such a mundane matter as the voice, but technology adoption lessons show that it only takes a small bit of discouragement to ruin a user's experience and send a tool they could really use straight into their recycle bin. Demos and warnings could be added to specifically address Synthetic Voice Shock and show off the awesome benefits to be gained. The choice of a freely available voice is a perfectly rational design decision but may indicate a lack of sensitivity to the needs of those newly losing vision forced to learn not only the mechanics of a tool but also how to lis en to this foreign speech.
You may need to seek out better speech options, even outlay a few bucks to upgrade to premium voices or a low cost tool. Amortizing $100 for voice interface over the lifetime hours of listening to valuable materials, maintaining an independent life style, and expanding communication makes voices such a great bargain.
And, who knows, many of the voice-enabled apps may help your own time shifting, multi-tasking, mobile life styles.
As I have personally experienced, it must be especially difficult to handle Vision Losers with constantly changing eyesight and a mixed bag of residual abilities. It could be very difficult to tell Vision Losers they might fare better reading like a totally blind person. But when it comes to computer technology, that step into the audio world can both reduce stress of struggling to see poorly in a world geared toward hyperactive visually oriented youngsters, especially when print disability opens the flow of quality reading materials, often ahead of the technology curve for sighted people.
The most useful training I can imagine is a session reading an article from AARP or sports Illustrated or New York times editorial copied into a version of TextAloud, or similar application, with premium voices. Close those eyes and just relax and listen and imagine doing that anywhere, in any bodily position, with a daily routine of desirable reading materials. To demonstrate the screen reader aspect, the much maligned Microsoft sam in Narrator can quickly show how menus, windows, and file lists can be traversed by reading and key strokes. The takeaway of such a session should be that there are other, perhaps eventually better, ways of reading print materials and interacting with computers than struggling with deteriorating vision, assuming hearing is sufficient.
In summary, more attention should be paid to the pattern of adverse reactions of Vision Losers unfamiliar with the benefits of the synthetic speech interaction that enables so many assistive tools and interfaces.
Ugh, the article's title itself is kind of stupid, a touch by an editor rather than the article's author. Indeed, Google is described as a monument to measurement technology in attempting to achieve the best all-around responsiveness to user queries, up to trying to read minds as represented by query histories. That's a worthy game and has changed the world but is not the crux of the article. The key idea is that a hyperlink from a web page you are reading is not only a reference but a propellant toward action, as Carr describes its effect. In the context of technology that encourages multitasking, impulsiveness, and need to be interlocked with others on myriad networks, hyperlinks could be considered harmful. Note: my hyperlink references are at the bottom of this post.
The phrase 'XX considered harmful' is a tradition in computer science, canonized by the late E. W. Dijkstra in a 1968 article where XX was 'goto', a programming construct. He argued that the goto statement in languages like the then dominant FORTRAN caused unnecessary errors and difficulties in reasoning about programs. Somebody tracing through the flow of code would encounter a goto then need to branch their thinking into the continuation of line-by-line code flow as well as taking up where the goto said to go. The problem was also at the other end, when reading code, you had little way of knowing what other code might jump there under unknown conditions. This generated a decade of articles and result that showed both theoretically and practically, very few occasions required a literal goto, that more attention to the algorithm led to code better organized using loops, cases, and exceptions. For example, a well designed loop could be replaced by a logic description of the changes made, no matter how the iteration was accomplished. After the ruckus died down, there were improvements in languages, practices, and pedagogy called the age of Structured Programming.
My question here is whether the complaints against the goto and the hyperlink are a useful analogy. Suppose I put a link here to the Atlantic Monthly online website. You might be tempted to stop reading my article right here in order to get to the original context. That's perfectly legitimate, but will you return to my thought stream or continue branching from the magazine article? or start a whole new thread of interest? Can you hold all the branching structure of your day's reading in your brain and browser history? This is a cognitive dilemma for both reader and writer, stemming from a simple html element. Our scholastic training to cite sources and to help the reader use hypertext technology to reach the source in an instant causes some grief for all of us.
Carr and others are saying that hyperlink-driven reading is making it more difficult for them to read longer articles in printed or online form and even reducing their ability to read books. Is this a genuine loss of some cognitive ability? or is it just a change in reading habits? In either case, is the effect reversible? As some blog comments suggest, maybe there are other reasons for the expressed discomfort, like burn-out, aging, or natural shifts of interest.
This discussion hit home for me for several reasons. I was a student of hypertext theory in previous career incarnations in the 1980s. Questions then were about types of links, e.g. clarifying, refining, challenging,... To cite one major example, Robert E. Horn elaborated numerous models of hyperlink for different kinds of documentation and uses. Design theorist Horst Rittel evolved the concept of issue-based information systems to address 'wicked problems', characterizing difficult social problems requiring intense collaborative analysis. This truly was the golden age of structured Hypertext before the WWW came along and offered goto style hyperlinks to everybody.
For my new reading style using a screen reader, hyperlinks are more often annoyances, as advertising, navigation's, privacy notices, and 100s of links I never plan to click but must traverse or avoid in order to get to the content of a web page. This means hyperlinks consume personal energy, which may be a partial cause of current reading discomfort. Every inline hyperlink is a decision point - go there? do that now? or later? abandon this article? If we made all these decisions consciously, we would feel even more the personal energy drain. I have learned how loss of visual acuity forces more attention toward energy management to accomplish most reading tasks and to overcome inevitable errors.
Since I went through a period of several months of painful reading, I have a tremendous appreciation for the reading technology I can now use effectively, as discussed in my article on 'tools, Materials, and strategies for Non-visual reading'. I really did almost lose it, not from attention but from sensory change. I still marvel that my brain can interpret the sounds coming from a synthetic voice and absorb the content as fully as I used to visually, or at least I think so. Wow, a synthetic voice is just a data file and algorithm, but what a difference these make to the print-disabled world!
As I rebuilt my reading skills, I have come to visualize my reading content as mostly a tree of subjects and articles, retrieved primarily by RSS, and represented in text and mp3 files. If I count in a half dozen daily newspapers retrieved by a pipeline of blind services, every day yields easily over 1000 articles, cached or retrieved by wireless. Reading this way, maybe 50 articles a day, is a very well controlled process because the temptation to take a hyperlink is very rare. In other words, my RSS client and News stand control me while I control my web browser. Although my ICON PDA supports hyperlink activation, my decisions are simpler without a browser. Do I read this article or not, based on title and context in the tree? do I read politics blogs now, later, or skip for a while? Which topics are sufficiently intriguing to switch into browsing mode for searching and exploration? When the tree gets disorganized or its retrieval profile changes, how do I reorganize the branches? all this helps reduce context switching and clicking through regions of inactivity. My non-visual reading regime seems to be much more structured than formerly, more focused on textual content than on links and relationships.
Yet, when my Icon Mobile Manager required a 2 week trip for repairs, I rather welcomed the respite from those 1000s of articles. I had to get my news the old-fashioned way, by airwaves on TV or radio, or by visiting websites. I was amazed at how much work I had to put in to set up the feeds and patterns I had evolved over a year with my Icon assistive technology. Upon return home of the Icon, I trimmed out a few feeds that seemed redundant or left over from previous interests, but mainly I place more time limits on my article reading. It also helps to have the Democratic party race out of the way.
Rregarding books, I do tend to skip around much more than in the past. Because I have a rich library of book files to choose from, I am evolving new interests and Reading patterns. I don't need to feel bad about not finishing a book as it can still reside on my memory card in an out of the way folder. As to concentration, most of my reading is insomniac style or on the road or for book clubs. Hey, maybe that's what carr and others need is a social book club with a list of questions for reading and discussion -- Do guys do that?
Ok, I am starting to ramble here. I have suggested the analogy between 'goto considered harmful' and 'hyperlink considered harmful'. My reading program with controlled separation of RSS delivered material from freestyle web browsing could be dubbed 'Partially Structured Reading'.I share, indeed I just know, that my brain has adapted to the forced changes of print-disabled reading styles by evolving its own techniques for decision-making, context-switching, and stack management. In my view hyperlinks cause two forms of harm. First, they encourage divergence without the convergence and summarizing techniques that enabled overcoming the analogous ill effects of the goto statement. Second, the current hyperlink HTML element that simultaneously expands and binds the web is a primitive instrument that cannot be used for serious thought without imposing some of the rigor of early hypertext theories, e.g. the purpose of the link.
I'd like to bring up a few more references on this topic from my audio channels and personal experience:.
Time to update myself, so I go to Google and find the usual results for the query "myopic macular degeneration". Top results are mostly generic overviews "MMD is related to AMD", but I also find a lengthy Myopic Manual.
For example, one controversial aspect of Albert Einstein was whether the first wife he dumped had contributed rather more to his research career than was acknowledged. Query for "Albert Einstein AND Mileva Maric" and, voila, the controversy is revealed in various levels of details and with arguments on both sides of the story. Bet you didn't know that! Using a synonym for controversy raises pages that discuss his personal life and produce the names, like Serbian physicist Mileva Maric, for additional searches. This particular revelation ebbs and flows with the tide of publications on his work and life. So, our approach is to use the language of human endeavors that involve research and the give-and-take of the intellectual marketplace to morph our searches more into the Analytic Web.
More seriously, for medical conditions, people facing surgical decisions want all and the most authoritative information they can get as fast as it can be found. So we offer the Controversy Discovery Engine as a kind of "second opinion" information seeker. Please provide feedback and suggestions to slger123@gmail.com. This web page may also be modified for similar uses with appropriate link and acknowledgement. If you're intrigued with this topic, which won me the proverbial 15 minutes of fame in the blogosphere, read the paper and its five examples: St. John's Wort, female astronauts, Albert Einstein, Belize, and distance learning. For the real search gurus, the software instrument used in this experiment, dubbed twURL, is available for licensing.
For visually impaired readers, here is a bit more advice. The web page has four form elements with the search query edit box at the top and submit button at the bottom and two list boxes with multi-selection in between for synonyms and support. You can multi-select from the list or select NONE as the last list item. Remember to turn on the virtual buffer in a screen reader to type in the query and select from the lists. Using sight, you might want to pump up the text size using your browser, e.g. Control + in Firefox. If you use this page a lot and know how to edit HTML, save the page and customize its style to your taste.
I consider myself an effective reader at this point in my vision loss. Three years ago I would have had no way of describing how I would be reading now. Partially, this was from the inability to know how my sensory apparatus would be working. For the record, I see pages where the text is mostly smudges. Computer screens have reasonably clear outlines with text that can be enlarged on a monitor or text size setting but remains often more like those irritating CAPTCHA boxes, all wobbly and sliced up. Partial sight can be minimally used by magnification, contrast, and eccentric viewing but for any reasonable way of consuming information, one must step over into the audio world. That means a screen reader or self-voiced reading devices, all using synthetic speech. After 2 years of hard work, a lot of technology evaluation, and countless hours of practice, the audio world now seems natural. I have no problem reconciling myself with this way of reading for the rest of my life, trusting that my hearing and hands will not give out on me.
So, that's all new technology I've learned in the past 2 years, ranging from my Identity cane to a suite of talking devices.
Note added December 08: Other sources of narrated materials are available in podcast format. Librabox podcast delivered book chapters is prolific and well done. Assistive Media Magazine readings extracts popular New Yorker style articles. State services like Arizona Sun Sounds offers books, newspapers, government information.
The beauty of the bookshare distribution system was immeasurably enhanced by the Icon's integration of a book search and download capability. If I hear about a New York Times best seller , a classic or a Reader's choice, I can pull up the Icon book search by title or author, automatically log on to bookshare, download the book, if available, and start reading -- in about a minute! Of course, if the book is not available, I can look for an audio at the public library or a commercial service or get a printed copy to scan. Indeed, I am now contributing books selected by my monthly AAUW book club, which takes several hours of work as I learn to expedite scanning and editing with the Kurzweil 1000 system. But it's gratifying to know this process offers good readings to thousands more people like me. I carry my entire library on my easy reading Book Port categorized as Fiction, Biography, etc. and can also search these books in full text format. This pipeline of easily retrieved and stored books has truly broadened my reading choices with more than enough entertainment, enlightenment, and information.
Whew, this is getting long, as I inventory my reading experience, but here some the happier parts.
Two cool things about RSS are the ability to hierarchically structure feeds and to exchange feeds among readers. If you want mine, here's susan's reading sources , a file that can be imported into your choice of RSS reader or cribbed from in a text editor. Since all navigation in the Icon RSS reader is within a tree, I have a hierarchy of News into general, technology, Politics, and science categories, then further in places into trees of blog or other special content. Since feed updating is time consuming, maybe half an hour, the tree structure allows updating only a single feed or group of feeds, e.g. if I need a politics fix late on a Tuesday primary day. Of course, I also have several mailing lists with associated folders in the Icon email client, keeping up on mdsupport.org,book port, bookshare, NVDA, and icon user discussion lists.
To be provocative, I estimate my reading productivity now, compared to a few years ago, as about 10:1 in retrieving content available via Internet, wireless, RSS and other clients. Once retrieved, I feel about a 10:1 gain in ability to scan, filter, selectively read or listen to the content. Of course, I cannot get everything I need and occasionally rev up the Icon or PC Firefox web browser for searching and surfing. I'll discuss my feelings about information overload and reading habits and brain plasticity in the companion post on "Hyperlinks considered Harmful".
One of the greatest benefits of exploiting vision loss and using these reading tools is that advertising fades into the noise. Given the current economic model for most information services, this makes me a lousy consumer. Well, too bad, I really would like to kick in for a low-cost subscription, say $10, but do not have that opportunity. I'd like to pay $3 for each book I read with funds to the author and publisher, like is occurring for music. But my guilt is assuaged by taking every opportunity to tell in person and virtually about resources I like in hopes that enough people will click the ad links and buy the resources directly. And, much as I love my reading tools, losing vision is costly, nearly $10k for the above tools.
For those losing vision, as I have for three years, I urge you to begin tapping into this audio world sooner than your denial and hopes might lead you. Try using a free screen reader and audio conversion tools and get used to gaining more information by audio whenever you feel discomfort with your eyeballs glued to your screens. I hope this article assures you there are many ways to adapt your reading styles to meet your needs, and even to find gains you never dreamed of. You might visit a disability services department at a local university or an assistive technology demo exhibit hall. But beware, that the rehab and disability services personnel are themselves grappling with technology learning curves and are locked into vendor distribution practices that lag behind some of the tools I advocate in this blog. A good starting point, whatever your level of sightedness, are the user stories in nextup.com text to speech blog
Most of this post assumes a state of experience comparable to mine three years ago before I became print-disabled. It was hard then to know what questions to ask to prepare myself. I bumbled through using the TextAloud reading application which enabled me to write well enough while I could control the lighting around my PC and begin to experiment with alternative screen reader packages. Unfortunately, I had some truly humbling experiences trying to edit rapidly at review panel meetings with overhead lights bearing down, voices all around, and a formidable web-based panel review system. Following the edict "Do no harm" I recognized a challenge of physical, cognitive, and technological dimensions. I had to admit I was professionally incompetent when it came to writing, ouch!
The basic questions are:
If you are not sure how this writing process is working, listen to me writing some text using the NVDA screen reader.
The Accuracy Versus Speed Tradeoff is intrinsic to writing. How fast do you record your thoughts, accepting some level of typing and expression errors, with separate clean-up edits and rewrites? If I type very fast, I make more errors but am better able to record the thoughts and even establish a "flow" mental state. Writing more slowly allows corrections of wording, punctuation, and spelling but risks loss of thread and discouragement from a feeling of slowed progress.
Writing and editing are very different cognitive tasks complicated by operating primarily in listening mode. The input and output parts of the brain must operate together. A document filled with typos is pure agony to correct, causing a cascade of further errors and often destroying the structure of the whole document. One twitch in a edit can remove more than a letter, even a line, sentence, or paragraph. In "computational thinking" terms, the trade-off is to design the interactions of two concurrent processes that interleave events and actions to produce a document with an optimal amount of errors to be removed by even more processing involving editing tools. I tried several drafting techniques. Writing in long hand notes, outlines, and snippets had worked for 40 years but I could no longer read my hand-writing. Recording into my Icon PDA helped organize my thoughts and extract some pithy phrases from my brain. As my memory has improved to take over former vision-intensive tasks, I have found it possible to mentally compose a paragraph at a time then hold it together long enough to type into the word processor.
Writing without looking requires several tools, with my choices discussed below:
. On the upscale side, I needed a scanner manager for books and Other printed stuff. The Kurzweil education Systems 1000 offers not only scanner wrappers but also several word processor features. One is a beautiful spell checker to read context, spell the word,offer alternatives all using its own self-voiced interface. Listen to me and the K1000 spell checker. I also like having a reader with alternative word pronunciation, pausing, and punctuating. However, I occasionally lost text due to lock-up and unpredictable file operations, so I opted for the universal, simple Notepad for composition.
Update December 2008. I am now using the free Jarte editor based on Wordpad. Behaving like the Windows Wordpad, Jarte has a spell checker similar to K1000, multi-document management, and other features. Most importantly, the interface recognizes and cooperates with a screen reader, NVDA for me. Carolina software designers have done a great service for visually impaired writers and should serve as a model for interface developers of other software products. I'll be upgrading soon to pay for the free version and some extra features.
As discussed in NVDA screen reader choice posting, I do not use the conventional expensive screen readers in favor of a free, open source wonder the I expect to rule the future of assistive technology. NVDA allows me to switch among voices, choose key and word echo, and degree of punctuation announced.
Writing and reading by listening has surprising consequences. First, it strongly differentiates sighted readers from those listening who will probably not hear the colon you use to start a list of clauses separated by semi-colons. Second documents must be read multiple times, with and also without punctuation announcements. It is difficult to concentrate on the sentences when every comma, quotation, and dash is read. And it is necessary to hear every apostrophe and other punctuation to locate extraneous as well as missing items.
Another suite of editing tools are synthetic voices, which may come as a surprise to many sighted as well as newly unsighted writers and readers. Synthetic voices have dictionaries of pronunciations but inevitably screw up in certain contexts. Is that "Dr." a street or an educational degree title? Is "St. Louis" the city with a saint or a street? is 2 the numeral like two spelled out or too as in also? No matter your screen reader settings and data, your readers may differ. Well, some of this can be tweaked but generally my attitude has been to just live with quirks.
Synthetic voices offer an even more powerful editing feature unknown to most sighted writers. The excellent researcher Clifford Nass" "Wired for Speech" tell how our brains react differently to gender, ethnic, age, personality, and other features of synthetic voices. Even if we know the voice is only a data file, we still confer more authority to male voices and react negatively to perceived aggressive female voices. This allows editors with synthetic voices to identify phrases with a tone that might be perceived as weak, over-bearing, age-related, or introverted. Don't believe me? Listen to examples of male and female voices.
Note to sighted writers: you might also find these techniques assistive for finding typos, checking style, and evaluating the forcefulness of your writing. Nothing says you have to be visually impaired to try writing by listening.
A very insightful article on writing for accessibility points out the ill effects of complex sentence structures, reliance on punctuation, expectations of emphasis, and unawareness of the span of settings possible on the end users side. Now, in my technical and business writing days, I was the "queen of convoluted sentences". I just never understood what was wrong with sub-sentences (as long as the sentence parsed ok); rather, I thought it a mark of quality. Whoops, there I did it again. I used a parenthetical phrase that might not be read with parentheses around it. And I relied on a semi-colon to separate sentences. Sorry about that, I'm working hard on this. But, there I made another mistake. I used a contraction which synthetic voices have trouble pronouncing "I'm" when I could say "I am". Abbreviations are also problematic. Should I say ER or E.R. or "Emergency Room'? This is giving me a headache.
The strongest lesson about compensating for vision loss is that 'Complexity really hurts'. Overly complex things, whether physical or informational, cause accidents and invoke recovery methods. All this wastes precious physical energy. It is easy to be discourage when tasks that could be performed before vision loss are now too expensive in energy or time. But, conversely, I can now see complexity for what is, usually bad design. And, on the brighter side, once the source of complexity is identified, there may be a work-around, a simplification, or a suggestion for a better design. All this conscious adjustment of expression practices may actually be good training for aging more gracefully. Sigh.
I am just coming off 2 months of travel to events in differing capacities as professional reviewer, accessibility spokesperson, disability consumer, and general traveler. After two years of legal blindness, I am still feeling like an immigrant in a new culture. I retain strong memories of my past ways of work and interpersonal interaction, but I am now beginning to understand the culture of disability. This transition has been marked by my adoption of the Identity Cane as a frequent companion as I navigate my hazy world.
The Identity Cane is a slim white cane intended not for robust walking assistance but rather to let others know its carriers are visually impaired. There are a few issues here.
First, consider robustness of the instrument. Mine, costing about $20, folds nicely and is quite light. It is good for poking at curbs and sidewalk spots that look like holes or ridges. But it is not for tapping or waving, as would be learned in a mobility training regime. One tangle with a fire hydrant or bicycle and this pole will be a pile of sticks. However, compared to other physical gadgets that seem to break for no reason, this fold-up item is holding up well.
The Identity Cane is meant to be a signal to passersby, service people, and new acquaintances that you have vision difficulties where they might help you. The other day, at an intersection, another street crosser seeing my cane just stated loudly "ok, time to cross", not knowing whether I could see him or how much help I needed. Airport personnel are alert to the cane to offer assistance to find elevators or check-in counters. A white cane can also gain more polite and helpful responses when you ask a stranger "where is the Saint Michael Hotel?" while standing directly in front of its sign.
However, this little pole is no badge of invincibility. Drivers on cell phones are just as likely to run over you whatever you are carrying, although the cane can be waved to possibly attract attention. Airport T.S.A. check-ins are variable, with some monitors wanting to stuff your cane onto the conveyor or into a box or frisk for objects planted on the blind lady. To my surprise, nobody ever asked when I went through security with my soon-to-expire Drivers License in one hand and a white cane in the other. A cane can help remind flight attendants you might need extra help but it might also enlist an unwanted wheel chair rather than a walking escort, if needed at all.
For me, the Identity Cane is an important reminder that I am partially sighted. I do not use it on my exercise walks along a regular route, but elsewhere it tells me "slow down, watch out for decorative stones that might send me to the Emergency Room, look for exit doors that might set off sirens, remember I can ask for help, never take a short-cut, generally behave like a person who cannot see everything".
Yes, it was really hard to get used to carrying the cane as an Identity. What if people think I am blind? Well, duh, Susan, remember your priorities - safety is paramount, energy is consumed by covering up, and relationships are hard enough without the ambiguity of a disability.
But it is not really that simple to clarify the cane's meaning if you are partially sighted. Having covered up my condition for 5 years with an uncomfortable employment situation, I became very good at navigating and acting normal. Except when I tripped or ran into something. Then I looked clumsy. Or when I skipped an event that was hard to handle for transportation or dining reasons,, I appeared unsociable or shirking. This is getting into more aspects of the culture of disability, where adopting the cane is an admission of vocational difference, a more than symbolic transformation of identity that demands organizational change in work or community groups.
Since low vision is a relatively rare occurrence condition the Identity Cane is a strong signal in the noise of everyday life. Never in my career had I seen a blind woman at a professional event, so my cane carrying at recent working gigs has probably been most unusual for other attendees. That is especially good for computing professionals to remind them that low vision is not just for their grandparents but also is part of the working conditions for someone performing the same tasks as them. If only it could also raise their curiosity to learn more about assistive technology, the afflictions of their students, the A.D.A. regulations they wish away, and the prevalence of accessibility issues.
For me, the Identity Cane is a badge of education, not only within my profession but also in the community that suffers from lack of low vision services. Visually impaired people may appear less often in public leading to a circle of ignorance. City fathers think "we do not need to pay for accessible street crossing when nobody blind wants to cross" -- but no sane blind person would risk their life at the intersection. This makes the Identity Cane a symbol of activism as well as a protective measure.
In summary, the cane used only for Identity is a strong force for overcoming vision adjustment resistance, personally, professionally, and for the wider public.
Here is
an example product description of an Identity Cane from Lighthouse San Francisco
Note: in the U.K. the general term is "Symbol Cane" . See also Podcasts discussing and illustrating functional white cane use for mobility
I set my PCs in High Contrast theme with a dark background, cuts down the brightness for when I can see the screen. "High contrast" is one of the standard changes made by the very helpful Windows Accessibility Wizard and is probably used by 10000s of low vision ppeople, as well as many sighted looking for a more restful background. Apparently, TurboTax download for state forms was not tested in this configuration as a nasty error message came up at the start of the transition to state form mode, usually a piece of cake compared to the federal form.
The recommended change to a "classic" or non-contrast theme did not solve the problem, namely a failure of a Continue button to appear. Nor is the intuit recommendation, to "well, just make a slight change in your system" trivial, as it's easy to screw up Display properties and also can be very hard to change back to High Contrast staring into a painfully bright screen. Sorry, intuit, that's not fair And it didn't work, anyway. Now, there is a free state CD on its way to me, responding to an 800 number, but not likely to get here before April 15. We did finish my taxes by moving to another household computer, and would have appreciated knowing of this pitfall to install there first. Thanks, again, intuit, for the advanced warning.
So, this is a pretty egregious screw-up by a major vendor, probably due to some combination of poor specification, lax qA, unfamiliarity with accessibility settings, and not many visually impaired testers in the intuit world.
Of course, I wasn't trying to do my taxes alone, but rather to avail myself of some in-house teenagers with fast fingers to enter the data I compiled and explained to them. Indeed, I use tax preparation as a way to impart some financial lessons, explaining terminology, re-inforcing "income vs. expenses", and, unfortunately, occasionally demonstrating confusion from lapses in record-keeping. This extra glitch didn't help our family morale at all, nearing 90% done, and ready to move on to more fun activities.
I'd be interested in hearing from other visually impaired people:

This post speculates about alternative changed futures for accessibility, such as cost-busting open source developments; self-voicing interactions; over riding inaaccessibilityty by proxy web servers; a screenless, voiced, menu-driven PDA; and higher level software design practices.
Wow, this little piece of software Youtube to iPod converter really delivers and opened up a new way for me to get useful web information. The use case is: copy the URL for a video that interests you, the link you would click to invoke the viewer; paste the link into the accessible converter; choose a file name and location; choose the format type mp3; click "download and convert"; wait a while; listen to the mp3 or your PC or send it on to a digital player, in my case my Bookport from aph.org. With a bit of imagination and patience, you can mentally fill in the video and also have a version to replay or bookmark. Moral of this digression: once again podcasts from the blind community open new worlds for us new vision losers needing accessible software to stay in the mainstream. Thank you, blind cool tech podcaster Brandon Heinrich! Check out my page of Youtube converted videos on eyesight-related topics.
University of Washington Research: Screen Reader in a Browser by Professor Richard Ladner and graduate student Jeffrey P Bigham in the Web Insight project at cs.washingting .eduBriefly, this experimental work addresses the problems of costly screen readers and the need for on-the-fly retrieval of web information by blind users away from their familiar screen readers. The proposed solution is a browser adaptation adding a script that redirects web pages to a so-called proxy server that converts the structure of the page, known as its document object, to text and descriptions that are returned to the browser as speech. This is pretty much what a desktop screen reader does, only now the reader and speech functions are remote. Of course, there are a gazillion problems and limits to this architecture but it appears to work sufficiently reliably and rapidly to achieve the social goals of its name, "Web Anywhere". This research project, funded by the National Science Foundation, has also used the above architecture to modify web pages to add ALT tags from link texts, OCR of the image, and social networking tagging of images. Not only is the technology very clever, but also the work is based on observations of how blind users use the web and on a growing appreciation of the complexity and often atrocious design of web pages and use of AJAX technology that frustrate visually impaired web users, no matter the power of their screen readers or magnifiers or their skills.
As a former employee of funding agency NSF, a reviewer of dozens of proposals, a Principal Investigator in my sighted days on Computer Security education using animation, let me tell you this U. Washington project is a great investment of taxpayer funds. The work is innovative, well portrayed for outreach at at webinsight.cs.washington.edu, addressing monumentally important global and social issues, and helping to bring about a better educated and motivated generation of developers and technology advocates on accessibility issues. Now, is this proxy-based architecture the killer app for web accessibility? Possibly, with widespread support of IT departments and developers, but the project sets it goals more modestly as "Web Everywhere" for transient web uses and possibly more broadly to address the cost of current screen reader solutions. Maybe the proxy-based approach can be expanded to other uses in demonstrations and experiments on a range of accessibility problems.
The value of a universal screen reader is that it can do something useful for most applications by dredging out fundamental information flowing through the operating system about an application's controls and its users' actions. But another model of software is so-called "self voicing" where the application maintains a focus system that tracks the user's actions and provides its own reactions through a "speech channel", providing at least equivalent information to an external screen reader. Such a model can do even better by providing flexible information about the context of a user event and preferences. A button might respond upon focus with "Delete", or "Delete the marked podcasts in the table", or repeat the relevant section of the user manual, or elaborate a description of the use case, such as "first, mark the podcasts to delete, and here's how to mark, then press this button, and confirm the deletions, after which the podcast files will be off your disk unless you download them by another name". Self-voicing as speech technology is implemented by many applications that allow choice of voice, setting speed, and even variation of voices matched to uses, e.g. the original message in an e-mail reply. More significantly, self-voicing puts the responsibility for usability of the application directly on a developer to provide consistent, coherent, and useful explanations of each possible user interaction. Further, this information is useful both to the end user and to testing professionals who can check that the operation is doing what it says, only what it should, and in the proper context of the application's use cases. Ditto, a tech writer working with a developer can make an application far more usable and maintainable in the long run. So, we claim, that a kind of killer app development practice would be the shift of responsibility away from screen readers onto self-voicing applications, including operating systems, where development processes will be improved. We base our claims on personal experience developing a self-voicing podcatcher, @Podder, for partially sighted users using a speech channel of copying text to the clipboard to be read by external text-to-speech applications. Another self-voicing application is Kurzweil 1000 for scanning and document management, and employing the nicest spell checker around.
Maybe, somewhere out there is a wondrous software package that will dramatically boos the productivity and comfort of visually impaired computer users. With some assurance, we can recognize an upcoming generation of open source oriented developers seasoned by traditional assistive technology and adept at both project organization and current software tools. Funders and support organizations can look ahead to utilization of their innovations and improvements. But maybe the core problem is much harder, as we claim, a disconnect in "computational thinking" between software designers who have found their way through models and user-oriented analysis and those web designers stuck at the token and speechless GUI level of browsers and web pages. Empirical researchers on accessibility are starting to witness and understand the fragility of users caught between artifacts designed for sighted users and clumsy, superhuman emulating tools such as screen readers and magnifiers while the proper responsibility for accessibility falls on developers who have yet to appreciate the power of readily available speech channels along side graphical user interfaces.

This posting lists several good and bad examples of web accessibility and usability situations in an instructive sense, including recorded sessions of this intrepid logger guiding her web page readers.
The unfortunate user must expend extra energy to read surrounding context to find what the click is for. This mistake usually indicates poor communication skills and lack of testing using a screen reader. variations include: Learn More, read more, and the especially illuminating here. similarly, a document may be identified then followed by its type a line like PDF or HTML or size 5 MB.
conventional web layouts contain site navigation, rolls of links to related content, meta data about site and author, news, etc. screen readers follow a left upper corner, top, left, order that forces reading or bypassing links to reach actual page content, which sighted readers look for in the middle of a page. a repeat visitor rarely has interest in these links. blog and other content management systems usually provide a choice of page layout Reading a links-first blog format takes up screen reader time, even with a jump to heading. More disastrously, an RSS client often receives all the links on a text version of a posting, taking a minute or more to read before content, making some blogs effectively unbearable in RSS format.
Recommendation: Design pages and choose layouts to favor quick access to recurring content, placing honorific stuff right and below what your main page matter.
Examples: two of my favorite tech blogs, Good example: Jon Udell blog and Bad example: Phil windley's technometria.
we all know to sprinkle headings through our documents to break into and describe sections, even applying this to bills and forms. for a screen reader user, headings provide the primary way of moving among sections, often preceded by an exploratory "heading tour" to identify the page sections ahead. without sections, the screen reader's finer detail units are links, lists, and paragraphs, but this rapidly degenerates into interminable tabs and keystrokes like taking steps into a cave without knowing where the path will lead. conversely, a well-sectioned document also broken into pages can be very rapidly browsed with a screen reader, perhaps even faster than a scrolling sighted reader. can cover graphics and font styles. Chunks of text can be skipped for more detailed reading later. Nothing substitutes for having a sense of the page's structure in outline form.
Recommendation: Make sure all page sections are well described by HTML H1, H2, H3,... headings with informative descriptions. Now, is that so hard?
Examples Good example: sxsw.com"> program organized by days and topic and Good Example: browsing wai-aria documentation
Browsers are now integrated with external applications like Microsoft word or adobe PDF. but that meanss a screen reader user must first launch that app, and, of course, MS OFFICE is not free! reading the document involves a different set of keystrokes and conventions with PDF often losing any previous document structure. Ironically, frequently, the document being read is little more than text any way! This vision Loser simply saves DOC or PDF and then strips the document down to TXT for reading in Notepad or on an external reader like APH Bookport or Levelstar Icon. With gratitude, another path is google search "View as HTML" and HTML save As in mobile gmail. This argument also applies to mail attachment -- imprisoning text memos in a WORD format attachment requires a lot of extra work by a visually impaired recipient, and "click on attachment" is often a security risk.
Recommendation: Web authors should save a version of a document as HTML and Make that a primary link, offering a PDF for portability (that's the P in PDF). HTML is the document format that literate web writers should be using, e.g. to exploit hyperlinks, and not at all the private domain of web designers and New Media or IT departments. Strictly speaking any PDF should be produced in accessible format for extensive reading.
recently, one of my favorite podcasters started live chat sessions with call-in. I wanted to ask a question and join in so showed up at the web page at the appointed time, having pre-registered and browsed the site the day before. Uh, oh, I couldn't find an entry point, didn't even know what I was looking for. worse yet, an audio had started playing - was that the current session? No, it was prerecorded, drowning out my screen reader with no way of silencing the cacophony. Eventually I waded through a ton of links to other shows, popular podcasters, special offers and found a PLAY button. Now, all this with a screen reader contending with an audio discussion, and then the text chat was completely inaccessible to the screen reader. well, that podcaster lost a fan's admiration for choosing BlogTalkRadion as a meeting place uncomfortable for me. The key problem was that the main purpose -- to bring people together -- was obscured by the now socially acceptable business practice of trying to draw attention to other podcasts and \shows - current, popular, categories, rated, which we term "social media over-kill". The irony is that the blind and visually impaired communities have superior chat facilities, as exemplified by accessible world.org, built on Talking communities supporting happily chatting friends of Bookshare book club meetings.
Recommendation: when choosing a hosting service, check out its accessibility policy, not just how free it might be, if you want to retain your whole audience and its respect. service providers, please write and follow an accessibility policy and stress its use to service users. service providers, content management system designers, and designer assistants all have a great social responsibility - and opportunity - to be inclusive and to educate service users.
consider if you know exactly the book you want to buy at amazon or another big web seller. a trip into amazon takes you through myriad departments of other types of products, offers Recommendations, specials, bundles, and even a chance to become a reseller yourself. but all I wanted to do was get that one book into my cart! Well, luckily, limited screen space on phones and PDA's is leading to overhauls of web sites to alternatives that offer simple and straight paths to the most common goals for impatient, on-the-go users. contrast clutter full scale amazon.com with accessible, mobile amazon.com . Now, not all of Amazon is on the accessible alternative, and they don't tell you what's missing, e.g. changing an e-mail address in profile.
Recommendation: web designers can take the opportunity to produce an accessible version of a site along with a mobile-friendly or mobile-optimized version. and don't forget to tell screen reader users with a non-intrusive link at the top of the page to the alternative. and, save the specials and Recommendations until after the sale.
It's not just me, the usability literature notes something like 5 times longer for visually impaired form-fillers than sighted users. problems include: identifying required versus optional and what actually goes in a field; non-standard formats for dates, social security numbers, phone numbers; unpredictability of length of forms; time-outs and site failures; and difficulty finding the notification of errors or requirements for verifications. Then there are all those registration "opportunities", without explanation of benefits of registering, without acknowledgment of the pain to be incurred. No thanks, no forms please. Is there a better way? Maybe, as suggested by Jon Udell's article on batch form-filling for civilians suggesting the use of text strings completed by simple editing and input to an API or query processor. geez, this is so brilliant!
Recommendation: web designers should take every care to label all fields clearly and acknowledge the time and pain of a visually impaired user. If possible, watch one of us use your form until you cannot stand the pain any longer. and recognize the difference in skill levels and experience and tenacity of a broad audience. forms are where you capture or lose a client. and, don't even think of putting a graphic only CAPTCHA at the end at risk of eternal damnation. On the other side, visually impaired users need to practice form-filling and accept it as a necessary evil that could ruin your day. We all need to look for better ways, like Jon Udell's text line suggestion.
Rarely am I completely stymied but far too often the energy required is the limiting factor. I use the "minimum of 5 times " rule to estimate effort required for a task, based on memory of past trials. Often, just the thought of the work involved deters me from trying a web site, like registering and then facing a CAPTCHA, maybe putting off to a future idle day. Flippantly, I wish all young web designers would test their web sites during a bout with the flu, so they might appreciate the effects of reduced energy on every click and key stroke.
A second observation is how much the web is overly populated with extremely complex web sites, exacerbated by the trend to social media linking. Every link bypassed in a blog or information page is a decrement in energy available for reading, navigating, information seeking, and transactions. Web designers often seem to cram too many functions onto pages and fail to identify the primary use cases and prioritize for screen reader users. I am delighted at the trend toward mobile friendly pages as very helpful in countering complexity and offering redesign opportunities.
In recent discussions with web accessibility practitioners I sometimes found myself thinking as the beggarly, or maybe miserly,old lady who could not shell out $1000 for an industry standard screen reader like Jaws or Window Eyes and got stuck with a third world open source software tool. There is some truth in the monetary argument as I fail to fall into the social services classes: veteran, worker, job seeker, student, or poverty level. But I have also made a technical choice in screen reader, nvda, based on confidence in its developers, satisfaction with its early capabilities, ease of use and installation, and belief in the efficacy of the open source model of development. I also am concerned at a shaky industry chain of developers, screen reader vendors, and rehab organizations that will soon be coming under more international pressure as a free screen reader takes hold in other countries, perhaps with easy adaptability for local languages and web conventions. I cheer for the Australian Torvalds of assistive technology.
Finally, I find myself moving away from the PC and browser with increasing use of the Levelstar Icon PDA. News comes from the NFB News line to Bookshare to the Icon's Newstand without a visit to a slow web site. Blogs and feeds bring more news from CNN, USAToday, CNET, and many political and professional organizations -- again obviating a browser session in favor of RSS. And the Icon's little browser often suffices for comfortably reading search results, pages, and blogs not embroiled in JavaScript/AJAX interfaces.
Unlike the other essays in this blog, the current post is a link to a resource page about a local community. I have often been frustrated at finding information about events and services, occasionally learning valuable tidbits first from my walking companion, Jack and his dog pack.
My hope is that other Vision Loser's in the Prescott area will find useful items and that community members will contribute to this resource.
The Vision Loser's Guide to Prescott Arizona lists local social services, RSS feeds, and pointers to state and national organizations.
