Gesture sensing interface: Phone conversation with hand gestures

A gesture sensing interface is on its way, if we believe the news mongers. Being developed by Patrick Baudisch, professor of computer science at the Hasso Plattner Institute in Postdam, Germany, and his research student, Sean Gustafson, the gesture sensing interface will require no physical input device like touch screen or a keyboard. Instead, a small video recorder and a microprocessor attached to the user’s clothing will capture and analyze all the hand gestures. When all the gestures are analyzed the outline of each gesture is sent to a computer display, allowing an equally good phone conversation.

Basically the idea behind the project is to use an imaginary interface to illicit a phone conversation, which will be aided by tracing shapes of fingers in the air. Take for example, the user draws a curved line with his/her finger, it will be captured by the already worn camera and sent to the mobile device, consequently displaying it on the screen. You also open the interface by just making an L shape with your fingers, creating a boundary for the forthcoming finger movements. Baudisch says, "Users start drawing in midair. There is no setup effort here, no need to whip out a mobile device or stylus."
