A new technology that can sense hand gestures on the human body, everyday objects and even liquids was demonstrated by researchers at Disney Research.
They believe the new system - known as Touche - will do away with touch screens and allow users to answer mobile phones by simply gesturing on the palm of their hand, the Daily Telegraph reported.
The technology works by using a sensing circuit to monitor how the electrical signal passing through an object changes when touched by a conductive material - such as a human finger- they said.
Using multiple frequencies, the system can distinguish the touch of a single finger, multiple fingers, a full-hand grasp and many other touch gestures.
The sensing electrode attached to the object and a computer is able to analyse the changing signals to identify the particularly gesture in use.
The team at Disney Research in Pittsburgh, Pennsylvania, claimed that the technology could be used by people to control an MP3 player by using touch gestures on their own body
"One day mobile phones could have no screen or buttons and rely exclusively on the body as the input surface," the video demonstration stated.
They also demonstrated that the gesture sensor could create a smart doorknob that knows how it's being grasped and then trigger different functions.
