THE GRAIL PROJECT: AN EXPERIMENT IN MAN-MACHINE COMMUNICATIONS

摘要: 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 RAND Tablet and stylus. The design goals for this were (1) to provide man-machine communication only CRT display real-time interpretation stylus motion, (2) minimize ambiguous responses make operation apparent, (3) responsive with minimal distraction delay, (4) compete as problem-solving aid. Computer programming via flowcharts was chosen demonstrate techniques. System on include location virtual position stylus, ink track representing its motion tablet, changes intensity, pictorial modification, English-language statements. important results investigation is demonstration such an approach.
