Abstract

A motion sensor having a coiled member, light emitter, and light detector. The coiled member is bendable in response to lateral forces applied thereto. The coiled member defines an internal open ended channel having a first end opposite a second end. The emitter is adjacent the first end and emits light into the channel. At least a portion of that light travels through the channel toward the second portion. An amount of light reaching the detector is determined at least in part by how much the coiled member is bent. The detector is adjacent the second end and receives light from the channel. The detector is configured to transmit a signal indicating an amount of light received. The signal may be used by a motion capture system to animate a computer generated animation. Multiple motion sensors may be incorporated into a glove and positioned to detect bending of finger joints.
