tudent working atM. I. T.s Lincoln Laboratory from 1960 to 1962, tooka pioneering step in proving the feasibility of man-machine graphical communication with cathode raytube and light pen. His SKETCHPAD programmingsystem has become a classic in the field. Project MACat M. I.T. has been a major national program ofresearch on advanced computer systems and theirexploitation. Researchers there have made originalcontributions to the use of computer graphics ineducation by creating artificial environments — as,for instance, a display in motion on the cathode tubewhich simulates a trip down a road at near the speedof light. The Lawrence Radiation Laboratory at Liver-more, California is also active in the developmentand application of sophisticated computer graphics,particularly in the field of computer-made movies Cathode ray tube displays at graphic console of General MotorsDAC-1 system show flexibility of man-computer communicationin automotive design.

16 • A program to convert a circuit drawn on the cath-ode ray tube to a form from which the computer cancalculate frequency response. • Programs to place components in a circuit withinthe constraints of a grid on the tube to reduce totalwire length of all connections. • A graphic command language to set up commandstructures on the face of the tube so data can be trans-mitted to programs in a computer that previouslyaccepted only numeric data from punched cards. • A graphic data processing facility to provide stor-age of many schematics which can be edited in vari-ety of ways. • Computer programs to direct a numeric-controlledmachine tool to drill holes in circuit boards and/or toprecisely position components on the board. Uses of Simulation Because of its primary mission in support of com-munications technology, Bell Laboratories has, sinceit was established in 1925, devoted continuing re-search to studying the fundamental processes ofspeech and hearing. Now, modern techniqu
