You're at Ames.  Have you met the Moose?  This is a haptic mouse that one of
the programmers at Project Archimedes at Stanford uses to good effect.  

There is the hypothesis that one could present map information with the
outline
graphics sensible via haptics and the cities, mileages, etc. textual
annotations presented by coordinated speech or Braille.

With the advent of a commercial haptic mouse under $100, this gets
increasingly
interesting.

There is also a new attempt at commercializing a tactile mouse -- sort of an
Optacon on a puck -- that was showing at CSUN this year.  This can give you
the
illusion of a dynamic and electronically sharable Braille Graphic region.

Maps are certainly an area where it is desirable to generate some capability
for presenting at least rough line-drawn figures and perhaps a bit of texture
in the plane under the user's touch or muscular feel.  And use that as a base
for verbal annotations at key points.
