Creating touch-screens anywhere with interactive projected displays

Abstract

We demonstrate a system that combines steerable projection and computer vision technologies to create "touch-screen" style interactive displays on any flat surface in a space. A high-end version of the system - the Everywhere Display (ED) - combines an LCD projector with motorized focus and zoom, a computer controlled pan-tilt mirror, and a pan-tilt zoom camera to enable steering of interactive projections around space. A low-end version (ED-lite) enables creation of interactive displays using a portable projector and camera attached to a laptop computer. Unlike traditional augmented reality systems, the ED systems enable delivery of interactive multimedia content on ordinary objects without requiring users to wear head mounted displays or carry special input devices.
