Developed by Tom Defanti and Daniel Sandin in a 1977 project for the National Endowment for the Arts. The Sayre glove used light based sensors with flexible tubes with a light source at one end and a photocell at the other. As the fingers were bent, the amount of light that hit the photocells varied, thus providing a measure of finger flexion. The glove, based on an by colleague Rich Sayre, was an inexpensive, lightweight glove that could monitor hand movements by measuring the metacarpophalangeal joints of the hand. It provided an effective method for multidimensional control, such as mimicking a set of sliders.
