Visual research using com-puters and display devices has demonstrated thatstereoscopic depth perception is a simpler processthan was formerly supposed. This finding may hastenthe day when stereoscopic visual information can beprocessed automatically. A sizable group of experts at Bell Laboratories isworking full time on such problems to producesophisticated software which can further realize theimmense potential of the computer. As Dr. John has said, We are at the beginning. We cannothope to see the end. ■ Service mark of the Bell System 17. 41 i:
