I would be very interested to know whether anyone has investigated the use
of touch screens for visually impared users? I know it sounds silly but
developed a kiosk system about 5 years ago using a touch screen. Not
accessible but as a mildly amusing asside, because I had to stick my face on
the screen to read it my nose kept triggering click events which opened
unwanted applications and navigated away from the page i was reading!!!
Maybe we need a nose down event handler!! Anyway, these kiosks are becomming
ever more popular and I have recently been asked to give some feedback on
another kiosk project. I thought that it might be possible to use speach to
describe menus on screen (in much the same way as voice mail systems do) and
provide a number pad for input. This may not always be suitable
(particularly if you needed to fill out a textual form for example) but
could be used for ticket purchase or general information if designed well.
Speach recognition was another thought as that seems to be taking great
leaps forward currently.

Of course, you've still got the problem of how the hell you know where to
find the actual kiosks!!!:-)

and there were some real problems.  it depends on how the screen detects
the screen being touched.   
   I recently worked with a state agency that wanted to put in kiosks for
getting things from the agency.   however the screen had to be touched by
a finger..a pencil or artifical limb would not activate it......oops

so it was redesigned with an infared scan system that detects anything.
