Daniel J. Sandin is pioneer of electronic art and visualization. He is director emeritus of the Electronic Visualization Lab in the School of Art and Design at the University of Illinois at Chicago and also works at Calit2, UCSD. In 1969, Sandin developed a computer-controlled light and sound environment called Glow Flow at the Smithsonian . By 1973, he had developed the Sandin Image Processor, a highly programmable analog computer for processing video images in real time. In 1991, Sandin and DeFanti conceived and developed, in collaboration with graduate students, the CAVE virtual reality (VR) theater. Sandin has been concentrating on the development of auto stereo VR displays and on the creation of network-based tele-collaborative VR art works that involve video camera image materials, rich human interaction and mathematical systems.
