There are people more shy than me? >First of all, the lawyerly position: Doesn't matter what technologies are available: the guidelines say what they say, so the statement that something violates a checkpoint is true regardless. Ah, but when you get to lawyerly arguments, you have two choices. One, you can argue that you did or did not adhere to the letter of the law. Secondly, however, you can argue that _the law itself is flawed_. WCAG is going to be undergoing revision very soon, and it's possible that this very issue will be addressed. When _should_ you use textual graphics, and how do you use them accessibly? >But we can do better than that. >I don't think using a screen magnifier is as good as enlarging fonts. Yes, but I don't think that a screenreader is as good as providing a RealAudio stream. 1. When you use a screenreader, you have a lot less control over the specific voice that is read out loud. This has the effect of losing "branding" on a web site and making everything in the world speak with one tone. 2. A screenreader, even with aural CSS, cannot adequately convey the subtleties of human speech -- the particular intonations, subtle hint of a smile, emphasis on the right words -- that a real person can provide. This allows for the true intent of the author to be provided to the audience. 3. Screenreaders are expensive and represent an economic barrier to entry for web users which is eliminated if you use streaming audio; audio players are cheap or free, while screenreaders are expensive pieces of software. >In short, direct control of font, size, and color of all text is better than a magnifier. In short, a streaming audio file is better than a screenreader. Of course, that's not really my point. (Please, nobody argue on the merits of streaming media vs screenreaders.) My point is that we accept there is no need for web authors to account for non- visual output because the screenreader software exists and is available. Granted, it's not the _best_ way to get that information to those users, but it seems to work. Why do we believe that the current technologies don't work here? >As for turning off images to see the alt text versions of the buttons: well, then the person with low vision is missing other images on the screen, images which may be used appropriately. That's a browser issue; a user agent should allow you to selectively view and not view specific items, and there should be a keystroke command or a context menu item which says "Magnify Image" to allow each individual button to be blown up large enough to read. :) -- Kynn Bartlett <kynn@idyllmtn.com> http://kynn.com/ Director of Accessibility, Edapta http://www.edapta.com/ Chief Technologist, Idyll Mountain Internet http://www.idyllmtn.com/ AWARE Center Director http://www.awarecenter.org/ Accessibility Roundtable Web Broadcast http://kynn.com/+on24 What's on my bookshelf? http://kynn.com/books/
