Now living in San Francisco, the Chicago-born Campbell holds degrees in mathematics and engineering from MIT. As an electrical engineer, he possesses more than a dozen patents in image processing and high-definition television; however, as an artist, he parlays his technical expertise into the aesthetic exploration of low-resolution video displays. In the mid-1980s, he transitioned from filmmaking to interactive video installations.

Campbell’s art consistently has probed into the questions of perception, time and memory. Much of his recent work harnesses the visual impact of LED (light emitting diode) displays, by transmitting digital video through LEDs, in order to create moving-image sculptures. But these works are not so much about an LED display as they are about the perception of a recognizable moving image through extremely low resolution and with very small amounts of information.
