THE GRAIL PROJECT: AN EXPERIMENT IN MAN-MACHINE COMMUNICATIONS

Abstract

An interactive software-hardware computer-graphics system has been developed in which the displayed contents of a cathode ray tube (CRT) can be manipulated directly using a RAND Tablet and stylus. The design goals for this system were (1) to provide man-machine communication using only the CRT display and real-time interpretation of stylus motion, (2) to minimize ambiguous responses and make the operation apparent, (3) to make the system responsive with minimal distraction and delay, and (4) to make the system compete as a problem-solving aid. Computer programming via flowcharts was chosen to demonstrate the techniques. System responses on the CRT include location of the virtual position of the stylus, ink track representing its motion on the tablet, changes in display intensity, pictorial modification, and English-language statements. The important results of this investigation is the demonstration of such an approach.
