Interface Uses Any Surface as an Input Area for a Mobile Device

Researchers at the Ishikawa Watanabe Laboratory of the University of Tokyo have created an interface called Anywhere Surface Touch, which allows any flat or curved surface in an actual environment to be used as an input area for mobile devices. The interface uses a small camera and contact microphone to recognize numerous kinds of interaction between the fingers of the user and the surface. The system recognizes which fingers are interacting and in which direction the fingers are moving. The combination of vision and sound allows the system to distinguish the contact conditions between the fingers and the surface. The researchers say that evaluation experiments have shown that users became accustomed to the system quickly.
