Too Much Accessibility

Hope­fully, any­one sub­scribed to this blog also fol­lows 456 Berea Street. If not, you missed a great post from Roger Johans­son titled Over­do­ing Acces­si­bil­ity. Go read the arti­cle and then sub­scribe to his feed.

Mike Cherim tack­led the same sub­ject awhile back on Avoid­ing Extreme Acces­si­bil­ity.

Bim Egan ran a whole series of arti­cles titled Too much acces­si­bil­ity — TITLE attrib­utes.

The two attrib­utes that were on all three lists were tabindex and accesskeys. The les­son? Take the time to under­stand your users, then eval­u­ate the work that you are doing to make sure it is actu­ally help­ing those you are try­ing to help.

CSS for Accessibility by Ann McMeekin

Day 13 of 24 Ways brings us CSS for Acces­si­bil­ity by Ann McMeekin. Ann dis­cusses the proper use of line-height for users with dyslexia and how to use the :focus pseudo class to let key­board users (even those using Inter­net Explorer) know when they are focused on a link.

Personas of Persons with Disabilities

I recently pre­sented on dis­abil­ity aware­ness in build­ing acces­si­ble web­sites to a group of inter­ac­tion design­ers. At the end, I was asked about exam­ples of a spe­cific per­son with a dis­abil­i­ties as well as design con­sid­er­a­tions for that per­son. This is what I found:

Per­sonas of Per­sons with Dis­abil­i­ties and Rec­om­mended Design Considerations

• Fluid, a user expe­ri­ence project for open source projects, cre­ated the per­sona of Sara Wind­sor, a fac­ulty mem­ber who is blind and out­lines some con­sid­er­a­tions in design­ing an acces­si­ble user expe­ri­ence for her.
• Liv­ing with Dis­abil­i­ties, pro­files for a blind per­son, low vision, hear­ing impaired, motor con­trol impaired, and cog­ni­tively chal­lenged, with design con­sid­er­a­tions for each– from the Uni­ver­sity of Michigan.

Per­sonas of Per­sons with Disabilities

• Two per­sonas– Roger Retiree and Kim, College-Student
• Exam­ples for Per­sonas from a Web Acces­si­bil­ity Project (PDF) , fea­tur­ing Tracy Young rep­re­sent­ing young peo­ple with visual impair­ments and Ger­ald Old­man rep­re­sent­ing old peo­ple with disabilities.
• Dis­abled Per­sonas from JA-SIG includ­ing Brent Blind­man, Melissa Motorim­paired and Clark Colorblind.
• Uni­fied Mod­el­ing Lan­guage Actors: “Per­sonas with Dis­abil­i­ties”, I’m not sure what the title means, but this arti­cle con­tains a list of per­sonas and a descrip­tion of how they were created.
• The WAI has a draft of the per­sonas that they used in their redesign, includ­ing a per­son with a disability

Regard­less of whether or not you use per­sonas, the exam­ples are help­ful to go through to bet­ter under­stand acces­si­bil­ity from a dif­fer­ent per­spec­tive, even though that per­spec­tive is that of a make believe person.

If the per­sonas aren’t doing it for you, take a gan­der at some of these videos and expe­ri­ences to get a bet­ter feel for how per­sons with dis­abil­i­ties access the web:

• Assis­tive­Ware videos on com­puter acces­si­bil­ity, don’t miss the user pro­files of the peo­ple in the videos (via Roger Johans­son).
• WebAIM Dis­abil­ity Simulations
• Screen reader and screen mag­ni­fi­ca­tion videos
