Invisible touch interface creates multitouch 'force field'

ZeroTouch can turn a traditional computer monitor into a multi-touch screen

Using infrared sensors like the ones on television remote controls, Texas A&M University students presented an inexpensive multitouch system at the Computer Human Interaction (CHI) conference in Vancouver.

"I like to consider it an optical force field; it's like a picture frame where we shoot thousands of light beams across and we can detect anything that intersects that frame," said Jonathan Moeller, a research assistant in the Interface Ecology Lab at Texas A&M University.

See the ZeroTouch system in a video on YouTube.

The frame is lined with 256 IR sensors, which are connected to a computer. When ZeroTouch is mounted over a traditional computer screen it turns the display into a multitouch surface. In a demonstration at CHI, Moeller played a computer game using multitouch controls and it worked without issue.
