MC2 Post 1576 Turning a Standard LCD Monitor into a Touchscreen

with a $5 Wall-Mounted Sensor.

From: http://www.extremetech.com

Researchers at the University of Washington’s aptly named Ubiquitous Computing Lab can turn any LCD monitor in your hous into a touchscreen, with nothing more than a $5 sensor that plugs into the wall and some clever software.

The technology, called uTouch, works by measuring the electromagnetic interference (EMI) caused by your hand when it moves near or touches an LCD monitor.

Sadly, the Ubiquitous Computing Lab doesn’t intend to commercialize uTouch, but co-author Sidhant Gupta tells Technology Review that the $5 sensor uses off-the-shelf parts, and the algorithms are included in the paper, so it would be fairly easy for you — or a commercial entity — to recreate the uTouch system.
