Magic finger points the way to universal interfaces

Scientists at Autodesk Research of the University of Alberta and the University of Toronto are developing a “Magic Finger” that allows any surface to detect touch input by shifting the touch technology from the surface to the wearer’s finger. Magic finger pairs a standard high speed sensor for movement tracking, much like that found in an optical mouse, with a high resolution camera able to detect 32 surface textures with 98% accuracy.
