Abstract

We have developed an inexpensive scanning laser rangefinder to measure the real-time position of bare hands in a 2-D plane up to distances of several meters. We have used this device to build a precise, multipoint “touchscreen” interface for large video projection systems. In this paper, we describe the concepts and hardware, plus outline an application for an interactive multimedia environment.
