In his reply he said, "Answers attached in a valid XHTML file. I would suggest at least retaining the id attributes. I copy-edited all the questions, but the words are all the same; they are now merely spelled and capitalized correctly. I think all the links work." Whatever. We left Joe's formatting intact.

What about blog-type sites in general? What can be done on these types of sites to make them more accessible? Mark Pilgrim has fully strip-mined this topic.

If you can see, it$B!G(Bs very easy to skim the page, and it is also very easy to zip to what interests you if you can operate a mouse or keyboard well. Nondisabled people have random access to the contents of a page. Many disabled people ? the blind and the mobility- impaired in specific ? experience a Web site serially, with one item after another articulated (as in speech or Braille) or selected. The page author can make skipping around easier, and so can relevant software like screen readers, but it$B!G(Bs still going to be harder to navigate than for a nondisabled person. Slashdot is dominated by words. The page introducing this interview carried about 6,900 words even with minimal comment expansion. The issue, then, becomes navigation, which I discussed in the previous answer. Adding hyperlinks to skip various navbars would be a good first step. Slashdot could certainly use better semantic markup. Valid code is a must; I want Slashdot to eat my own dog food. Subject lines of postings could and should be marked up as headings (h1 through h6); font elements could be eliminated; I$B!G(Bm not wild about table markup to achieve indention, though making structural hierarchies apparent is not easy at all (perhaps unordered lists with a style declaration of list-style-type: none might suffice). It would then be possible to navigate from heading to heading. If you$B!G(Bre running a more limited Weblog with just a couple of screenfuls of text at a time, then my advice is simple: Write valid code, provide a text equivalent for every image, work on navigation a bit, and you$B!G(Bve made a big dent in the problem.

I have good relations with the principals of an accessibility testing firm and believe the businesses can complement each other well. I$B!G(Bm a part owner of a Web development firm at the moment that isn$B!G(Bt interested in pursuing this market, but I believe there is a significant market. Can you elaborate on the market for Web development firms that focus on accessibility? Aside from the normal perils of launching a new business (which I$B!G(Bm fairly acquainted with), can you expound on the market need for firms that endeavor to deliver accessible content? $B!H(BDeliver[ing] accessible content$B!I(B and $B!H(Bstarting up a Web development firm with a focus on accessibility$B!I(B are two different things, so let$B!G(Bs focus on the latter. I would say that the market for accessibility-specific Web consultancies is rather small and will have a short lifespan. I can say this with some confidence as I am an authority on accessibility, with a published book to prove it, and I hardly get any business. Even taking other factors into account, I think it$B!G(Bs the nature of the work. I have various reliable indications that other consultants aren$B!G(Bt flush with activity, either. Why? Accessibility is neglected. People can$B!G(Bt hire you to do what they never knew needed to be done anyway. Nor will they hire you to do what they resent having to do in the first place and will resist doing until their dying breath. Contracts are small. Even very large sites tend to be run by CMSs or templates. Once you clean those up, boom, tens of thousands of pages become accessible. There is often not a lot of billable work involved, as I know myself all too well. Attainable expertise. If, as I contend, accessibility is merely one of the skills a competent developer must have, eventually all the competent developers will gain that expertise. They won$B!G(Bt need outside experts. Even if in-house access knowledge is demonstrably worse than outside consultants$B!G(B, there are all sorts of precedents for companies making do with barely-passable accessibility because it$B!G(Bs cheaper. There is a preference for meeting the letter of any requirements (whether self- or externally-imposed) rather than doing accessibility well. Now, what may work massively better is, in fact, accessibility testing (and certification). It is extremely difficult and time-consuming to test site accessibility with actual disabled persons using actual adaptive technology. A firm that updates Web sites to accessibility standards, advises on how to write new sites that conform, and tests them to prove it may be a winning combination. The issue of then certifying a site as being accessible (or meeting certain requirements) becomes a bit trickier, but I$B!G(Bd really like to see someone give it a go. Note that any venture like this will require thoroughgoing knowledge of the Web Content Accessibility Guidelines, the Section 508 regs, adaptive technology, and multimedia accessibility, and that knowledge definitely includes an understanding of exceptions to the rules. I deal with too many people who literally read and literally apply whatever guideline they$B!G(Bve decided is gospel. Accessibility requires human judgement based on knowledge and experience. Don$B!G(Bt set up shop without it. **What of dynamic images (charts and graphs)? by kuwan I see that Chapter 6 addresses the image problem which you state is $B!H(Ba core concern in accessibility.$B!I(B My question is, what is your solution to data-intensive sites that display their information using graphs? For sites that have constantly changing data (stock charts, for example), what solutions/tools are there to make their graphics accessible? The answer is that such information, in certain cases, cannot be made meaningfully accessible to a blind or visually-impaired person, or probably to a learning-disabled person. Other disability groups should be unaffected. This, of course, leads me to my perennial complaint about the Web Accessibility Initiative and accessibility advocates generally: They$B!G(Bve got no style. They have no understanding of graphic design and typography, and they project this ignorance onto the rest of the world. To use one of my maxims, accessibility opponents think accessibility means a text-only Web site and hate the idea, while accessibility advocates also think it means a text-only site and love the idea. They$B!G(Bre both wrong. One consequence of this ignorance of visual design? The implicit claim that every illustration can be epitomized in words. You could only make this claim if you were so visually unsophisticated that you couldn$B!G(Bt differentiate one kind of illustration from another. Of course, this is hogwash: The reason why we use illustrations is because words (or numbers) are sometimes too hard to understand by themselves. A graph of stock performance, radar weather maps, ultrasound images ? any picture that is worth much more than a thousand words presents a quandary. The goal here is accessibility ? a disabled visitor must have equivalent access to the information conveyed by the graphic. If the underlying data is numeric, in theory you could provide the underlying data (as through the longdesc attribute of the img element ? just set up an HTML file, or, theoretically, a spreadsheet or a PDF, that could be loaded to describe the illustration at length). But remember, all that numeric data was so hard to understand for nondisabled people that it was turned into a chart; now you$B!G(Bre expecting screen-reader users to wade through those numbers one at a 14:15:21 Like packing, unpacking, and repacking a suitcase, converting data to graphics and back again tends to leave something behind in the transformation. You may have provided a text equivalent in such a case, but you have not provided accessibility. I am not giving a carte-blanche exemption here. Many charts and graphs have one or two key points that could, in fact, be added to something as simple as an alt text: alt="Graph shows 12.2% increase in HIV seroconversion in gay males 18 to 24, 1996 to 2001". Even severely complex illustrations require at least a structural placeholder, like alt="Hubble photograph of Jupiter, its rings, and its satellites". It$B!G(Bs true that genuinely equal access to the information embodied in complex illustrations can be unattainable. These are exceptional cases, but they do come up.

The various Web boards that have supplanted them don$B!G(Bt seem like they would work as well (sorry, haven$B!G(Bt tried any yet; those Braille TTYs ain$B!G(Bt cheap). Yes, this is a personal question (see .sig). I need help with tech solutions for the deaf-blind. Please contact me via E-mail if you have any experience in this. Well, deaf-blind people are difficult to accommodate. They$B!G(Bre also rare: Though adequate population numbers are hard to find, perhaps 11,000 deaf-blind people live in the U.S. But in some contexts, the fact that they$B!G(Bre deaf has no bearing on accessibility. Blindness is the issue. Screen readers (manufacturer list) not only can turn Web sites and computer software into voice, they can also typically output text to Braille displays. (I wouldn$B!G(Bt call them $B!H(BBraille TTYs,$B!I(B since those are used to communicate by telephone.) Braille displays are fascinating, rarefied, and costly devices. Tieman, Freedom Scientific, and ALVA are notable manufacturers. Not all that many people use them, in part because not all that many people read Braille (maybe 10% of blind people), though essentially all deaf-blind people read Braille. Anyway, for a Web site that does not include multimedia, the fact that you$B!G(Bre also deaf has no influence on accessibility if you$B!G(Bre already blind. For a deaf-blind person using a screen reader with a Braille display, ordinary Web accessibility becomes the issue, though I$B!G(Bd say that navigation help becomes much more important there. Experienced speech-output users run speech at superhuman speeds (300 words a minute is not uncommon), meaning you can burn through a page, albeit in serial fashion, pretty quickly. Given that Braille displays provide one or a couple of lines of Braille at a time, it$B!G(Bs a more time-consuming procedure. Now, for sites that do contain multimedia, there is no viable option. An obvious course of action (requested by one activist group) would be to combine caption transcripts and audio-description scripts so that one could essentially read a text rendering of a videoclip, but there is no technology that can actually do that yet. (Yet. I have plans.) Combined script-transcripts of this sort have been attempted manually a couple of times (and I mentioned the idea back in 1999), but I don$B!G(Bt know of any research on how well it all worked. **Alternative (non-computer) devices by superflippy Increasingly, people are using non-computer devices (cell phones, PDAs) to browse Web sites. What alternative devices are disabled people using, and how are they using them in ways Web developers might not have considered (e.g. voice browser in cell phone)? I$B!G(Bm not really up on that topic. The PAC Mate is one such device; it$B!G(Bs essentially a screen reader without a screen or free-standing computer. **Accessible site, or accessible browser? by vofka I am a partially-sighted person, and I have to admit that I do frequently have difficulty with accessibility issues, particularly with large corporate Web sites which all seem to be full-flow multimedia blitzes which require 1600x1200 resolution or higher, and usually override the default browser fonts to make them smaller. However, there are a number of browsers, such as Mozilla (just one example, I$B!G(Bm sure there are others!) which allow the user to zoom the text on a page, to override colour settings etc. Though it is undoubtedly important for Webmasters to pay great thought to the design of their sites in terms of colour, font size and multimedia content, how much relative importance should be placed on browser design, and the browsers ability to override the design decisions of the creator of a site? It$B!G(Bs important and overlooked. It would be nice if we had a browser that actually supported all of HTML; we don$B!G(Bt (no, not even Mozilla). Then it would be nice if CSS1 and CSS2 were fully supported ? admittedly an onerous task what with the myriad interactions and the various ambiguities in the spec. At that point, yes, the user customizability in CSS and the many options available in HTML would presumably be up to the user to control. I think it$B!G(Bs ridiculous that the only really effective way to override a page author$B!G(Bs CSS is for you, the harried, humble Web-surfer, to write your own CSS declarations (don$B!G(Bt forget !important!) and activate the file in your browser, if that$B!G(Bs even possible. This is the sort of thing that should be built into browser preferences, available for easy use. The first time you start up a browser, it should explicitly ask you if you have any accessibility requirements; a lot of people don$B!G(Bt even know about what few customization features browsers currently offer. I$B!G(Bll make another of my analogies. Remember the lack of visual sophistication of accessibility advocates? They want designers to work at their level by providing accessibility, but they never seem to understand that the converse is also true ? accessibility activists must learn to work at designers$B!G(B level by providing good site design. By the same token, if page authors are expected to use every practical accessibility feature, then browser makers must be expected to support all of them ? and support them well. In the immortal words of Comedy Central, $B!H(BWe$B!G(Bve upped our standards. Up yours!$B!I(B See also: User Agent Accessibility Guidelines. **Physical vs. cognitive & political clout by Aquitaine Dear Mr. Clark, I am a Web developer for the Program on Employment and Disability at the School of Industrial Labor Relations at Cornell University. Web accessibility is a serious issue for us, and we try to keep abreast of innovative approaches to design so we can find that elusive place where universal accessibility meets intelligent and aesthetically pleasing layout. We recently spoke with Cynthia Waddell (one of 8 authors of Constructing Accessible Web Sites, also out fairly recently) on this subject, but I found her unwilling to commit to anything other than $B!H(Bsuggestions$B!I(B rather than real technical solutions. There are two sticky issues that I have encountered. The first is the notion of universal access. Mrs. Waddell indicated that, working with the W3C, she was coming up with a list of Web sites that met Priorities 1?3 of the W3C WAI and were still aesthetically impressive (she did not have a list ready). As you are no doubt aware, many sites that tout universal access are themselves victims of poor design -- the problem of $B!H(BYes, it$B!G(Bs W3C/WAI compliant across the board, but it$B!G(Bs ugly as sin.$B!I(B Do you believe that a site can have a single interface that is truly $B!H(Buniversally$B!I(B accessible, or do you believe that sites should have alternate interfaces? (The Web equivalent of $B!H(BDo we have a ramp and stairs or just a ramp?$B!I(B) Along those lines, it is apparent to me that the accessibility guidelines are designed to be useful in a manner proportional to the lobbying power of disability rights groups. That is to say, blind people and deaf people, although they comprise extraordinarily small percentages of people with disabilities, have an enormous amount of political clout when compared to people with cognitive disorders -- ADD, ADHD, dyslexia, autism, schizo-affective disorder, schizophrenia, et cetera. Because these disability groups lack the considerable power of a strong advocacy group, do you feel that they have been left by the wayside when it comes to Section 508 or WAI? (And do you personally believe that total- WAI compliance is necessary, or just Section 508?) My apologies for several questions at once, but we take this issue very seriously here and your answers will go a long way to helping us do what we do to better suit the community that ILR serves. Thanks so much, Samuel W. Knowlton To answer your first question: A single interface works for most Web sites. You can simply make the site itself intrinsically accessible ? to most disability groups. The only alternative the question seems to envisage is specifically custom-designing an alternative interface for disabled users. In other words, a site would exist in two or more predesigned forms. That$B!G(Bs not the only way. Some work is being done to permit people and the devices they use to specify formats and capabilities they may possess or require. Have a look at Composite Capabilities/Preferences Profiles. It all boils down to semantic markup again. A single HTML page, if marked up properly, could be visited by a plain-Jane browser and displayed in a way that$B!G(Bs familiar to nondisabled users; nothing special would happen. But if you had a CC/PP-compliant browser or other device, and if the page were coded correctly, and if the server understood CC/PP protocols, then the page would automatically reconfigure itself to your needs without the original page author$B!G(Bs having to do anything special. In fact, authors could not predict what kind of transformations would occur, nor would they care. So a few things could happen. If you$B!G(Bre totally blind, your page could be rearranged so the search box and content are at the top, with sidebars, navbars, and anything else uninteresting at the end ? and no images loaded at all. A low-vision person could ask for larger type on content sections and normal-sized type everywhere else, unless a command were issued to blow up, say, a navbar. (There could be continuous interaction between the user and the server.) XHTML 2.0 might push this concept along a little, what with its section element, but it$B!G(Bs all still a pipe dream, really. Now, as to the second question, putting blind and deaf people together in a group claimed to $B!H(Bhave an enormous amount of political clout$B!I(B is not really applicable to Web accessibility. Deaf people face very few accessibility barriers in using the Web ? multimedia is pretty much it. Blind people face very large barriers because the Web is a visual medium. There$B!G(Bs a qualitative difference. It$B!G(Bs true that people with cognitive disabilities have been neglected in Web accessibility. Why? Few people in the wider accessibility field have expertise on the topic. The Web Content Accessibility Guidelines 2.0, when it$B!G(Bs finished, will contain many more provisions for this group. The qualitative difference remains. It is arguably difficult or impossible to make Web sites ? most of which are dominated by text ? genuinely accessible even to certain specific groups with cognitive disabilities. Remedies proposed in the Web Content Accessibility Guidelines 2.0 drafts would not guarantee access for learning-disabled people. Some of those remedies involve adding illustrations ($B!H(Bnon-text content$B!I(B) to every single page (yes, the Web Accessibility Initiative may issue that requirement) or rewriting the page according to some kind of half-arsed, doctrinaire editing scheme. There wouldn$B!G(Bt be the same jump in accessibility between a noncompliant site and one that meets those guidelines as you would find with, say, visual impairment. Sites would end up being merely less confusing as opposed to not confusing. You might have met the spec, but you could not be sure you had achieved accessibility. Certain cognitive disabilities do not even require accommodation online. Moreover, while accessibility for many other disability groups almost never alters the visual appearance of a page (visible skip-navigation links are a counterexample), it could be argued that a page that$B!G(Bs truly accessible to people with learning or cognitive disabilities would have to be custom-created by experts. That$B!G(Bs the stark truth involved in achieving high accessibility for this group. You have to alter content as opposed to metadata or presentation. To accommodate other disabilities, you add information, like alt texts; to accommodate certain learning disabilities, you must remove or alter information. I am in favour of improved accessibility for cognitively-disabled persons, but I$B!G(Bll only support proposals that can be shown to actually make sites accessible to that group. I$B!G(Bm also not willing to destroy the Web as we know it ostensibly in order to save it for a disability group whose needs might not even be met in the process. Nobody has presented credible evidence that current proposals actually will work, and certainly the evidence supporting the current WCAG 2.0 proposals is weak. In other words, if we want to fix this problem, it$B!G(Bs going to take a lot more work. And to answer the final question, Section 508 regulations backhandedly incorporate almost all of the Web Content Accessibility Guidelines 1.0, but go beyond the latter in certain respects. Both guideline sets have all sorts of problems, but complying with either of them will assure reasonable accessibility for large numbers of people. *$B%D%C%3%_!"%3%a%s%HMs!JLuJ8$KBP$9$k%D%C%3%_!"%3%a%s%HEyBg4?7^!K(B #pcomment +
