London, October 29: Microsoft researchers have developed a system called SideSight that can allow a mobile phone user to control a handset placed on a table by wiggling his/her fingers in the space around it.
The technology was unveiled last week at the User Interface in Software and Technology symposium in Monterey, California.
Alex Butler, a researcher from the Sensors and Devices Group at Microsoft Research Cambridge in the UK, has revealed that the system derives its exceptional ability from infrared sensors that can pick up the movement of fingers up to 10 centimetres away.
"The big advantage of our prototype is the finger does not block any of the screen space," New Scientist magazine quoted Butler as saying.
