[SVHMPC] concept phone with only a touchscreen for UI

A possible solution for this has been discussed under an accessibility
thread. The Maestro is a simple (yet effective) clip-on cover for
PocketPCs. There are a few different versions of it, which work with
various different brands and models of PocketPCs. Check out a picture
The device is simply real buttons that, when pressed, place pressure on
a specific portion of the underlaying touchscreen. Real tactile feedback
without any hardware modifications to the underlaying device. A software
UI written to coincide with the specific button pattern is the only
thing needed. You also get the advantage of very specific pressure
points, allowing you to cram more "hot" areas into the UI than when
using direct finger input.
Now, what would be novel and cool for the Neo is if we could design a
clip-on device that was also mostly (or completely) transparent, so the
screen could be visible while still providing the tactile interface.
Keeping some of the various disabilities in mind while designing the Neo
& OpenMoko could really make it a hit in this sector. Pretty much every
phone solution out there for the blind is a real hack job, a system
capable of catering directly to these folks would be welcome. (FYI, I
work at a school for the blind).
