Pokey: Interaction through Covert Structure

Creating a multi-touch, bare finger, touchable surface by leveraging the invisible dynamic structure in the light cast by rasterizing, laser-based micro-projector. This work was intended to bring touch surface interfaces to next generation cell phones that will have cameras and micro-projectors with no additional hardware. While being low-cost we also needed a technique that would work in challenging environments like bars and dorm rooms where off-the-shelf computer vision algorithms would fail. Unfortunately the Mitsubishi Electric cellphone division was cut in 2008. Work done in 2007 and 2008. Presented at IEEE Tabletop in October 2008. Paul A. Beardsley, Yuri A. Ivanov, Biliana Kaneva, Shoji Tanaka, and Christopher R. Wren with special thanks to Chia Shen, Clifton Forlines, Daniel Wigdor for sharing their surface interaction expertise, to John Barnwell for running the Hardware Lab, and to William Yerazunis for making sure we didn't burn the place to the ground.
