Magic finger points the way to universal interfaces

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.
