Those who find the touchscreens on
their ever shrinking gadgets too fiddly to handle, will be glad to hear
scientists are developing a new touch surface... your own arm.
Developers
at Microsoft Research and Carnegie Mellon University are working
together to create an armband that projects an interface directly on to
your skin.
They have
combined a mini projector which creates a changing display with a
sophisticated sensor that can tell which part of your arm is being
tapped.
