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
at:

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.
i could have sworn that sonyericsson did something similar for a numpad
with their P800...
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).

Interesting ideas, but I'm not sure that any adequately handle the
tactile needs of a touch typist. Without looking at the keys, I can
feel the nubs on the home keys on my phone's mini qwerty to get lined up
again. I also have the same concern with using a laser projected
keyboard (even tho potentially high on the coolness scale). With just a
big flat surface then there's no way to keep you lined up on your keys
at speed. I type pretty fast on my mini qwerty. All my personal email
for the last few years have been 99.9% written on this thing, including
this one.

Well... for a while I was thinking about implanting a strong magnet
under the skin in one of my fingers to detect alternating current.
There are a few people out there who have done this and they say they
can feel a very mild wiggle when the magnet comes near a wire carrying
AC. It might be possible to detect the current going through the
touchscreen as you make contact with it.
But that's probably not a mainstream solution.
That sounds like a stelarc solution:

What about a glove or thimble that you could put on your finger?
How much does vibration tech. kill the battery on phones?
Some type of current detection sounds interesting...
