Multitouch Screens: The Natural Interface

We have built a 60″ multitouch table that will enable officers to collaborate simultaneously on mission planning and intelligence analysis. We have enhanced the traditional FTIR optics-based table with an overhead camera and computer vision algorithms that can track hand positions and individual users so that up to four people can work on a task simultaneously with both hands.Recent paper: K.
