An Invisible Touch for Mobile Devices From: Technology Review - 05/25/2010 By: Kate Greene Hasso Plattner Institute (HPI) researchers are developing a prototype gesture-sensing interface for mobile phones. The interface uses a video recorder and microprocessor attached to a user's clothing to capture and analyze their hand movements, sending an outline of each gesture to a computer display. HPI researchers Patrick Baudisch and Sean Gustafson envision users applying an "imaginary interface" to augment a phone conversation by tracing shapes with their fingers in the air. To start the system, a user "opens up" the interface by making an "L" shape with the left or right hand, which creates a two-dimensional spatial surface, a boundary for the forthcoming hand gestures. "There is no setup effort here, no need to whip out a mobile device or stylus," Baudisch says. The researchers found that users were able to go back to an imaginary sketch to extend or annotate it, using their visual memory.
