Abstract : A hardware-software system has been built which measures the three-dimensional positions of multiple points. In most cases, the points are light-emitting diodes which may be attached to wands, gloves, clothing, etc. The light-emitting diodes are easily distinguished from one another by flashing them on and off in sequence, under computer control. The position of a light source is measured by scanning the environment. Fast one-dimensional, geometric scans quickly determine planes in which a light source lies. The point of interest is at the intersection of these planes. (Modified author abstract)
