An Update From: PcPro.co.uk on LucidTouch

As a next step Microsoft researchers envisage a more compact prototype in which the touchpad
provides the image of the fingers without need of the clumsy webcam and boom. One suggestion involves a series
of light sensors which could map the movement of the fingers, while another involves tuning the capacitors in the
pad itself to detect the electrical field of the fingers.
“I can see LucidTouch changing the way users interact with PDAs and tablet computers, such as Microsoft
TabletPC,” says Baudisch. “In addition, I think LucidTouch will also offer substantial benefit for very small
devices. Think of a smart wrist watch featuring a touchscreen. If you used your finger on that touchscreen your
fingers would occlude the entire display. Using Lucidtouch, you would instead move your finger over the back of
the wrist band, yet the translucent overlay would map your finger motion onto the screen.”
