The TRACE group at the university of wisconsin - http://trace.wisc.edu - did
some work on making interfaces to kiosks so people could use alternative
access technoogies with them. But I don't have an exact reference to hand.

  developed a kiosk system about 5 years ago using a touch screen. Not

  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.
