How Would You Design a Captcha for the Deaf-Blind? 99
kesuki asks: "Right now, the state of the art captcha only works for the visually-abled. Some people are trying to start a grass roots opposition to catcha using existing anti-discrimination laws. However, without any captcha at all, spammers would have a field day. Audio captcha would work for the blind, of course, but they still leave out the deaf-blind using brail interpreters to use their computers and navigate the web. What system of captcha can you dream up that would work for the deaf-blind?"

Okay, this is a shameless plug, but I started work sometime ago on http://aomis.net/ [aomis.net] (I won't href it). Anyways, the idea was instead of CAPTCHA, which I don't really like, I thought why not let users identify different types of media. Now, I hadn't considered folks who were blind and deaf, but I did build the system to handle multiple types of media, like pictures and audio, which would help folks that are blind or deaf, but not both.
Now, the sites not quite ready, I'm still playing with a few things, like getting more media into it, but I'll have to watch this Ask Slashdot for good ideas on how to handle those who are blind and deaf.

I was thinking of such uncommon sites as slashdot.org (low karma users had manditory captchas to post, and they still may have random/anti flood ones) or perhaps Google.com's blogger.com which requires a captcha for every comment. I was also thiking of e-mail signups at yahoo.com hotmail.com mail.com etc. Anyone at anytime could loose both their hearing and their vision, either from infection, or repeated damage to the eyes and ears from say, deafeningly loud music and intensely bright lighting/lasers etc.
As rare as it is that a person is born deaf and blind, or becomes deaf and blind in childhood or adulthood it Does happen, often enough that companies interacting with millions of customers need to think about easy, affordable solutions to accomodate people unfortunate enough to lack both vision and hearing. some of the solutions people have thought of are really quite simple, so it seems quite disturbing to me that the last i checked of the major free webmail sites only mail.com seems to have a link for the disabled to go to to assist in signing up for webmail.

Since I'm still trying to figure out what you mean (even with the spelling correction), that wouldn't make a good test. You'd eliminate those who can't make an immediate distinction. The idea behind such tests is to show a human something that they can immediately associate and give the correct answer. Giving out word problems and puzzles will only aleienate 75% of your sight/hearing abled client base and probably the same portion of the deaf-blind you were trying to assist in the first place.
