<p>A minicomputer 16 controls a video disk player 18, a pair of CRT displays 12 and 14, interface electronics, and a memory device in the form of a dual floppy disk drive which stores software and lessonware. The student requests textural information and images by touching pressure sensitive panels on the CRT displays. The minicomputer translates these tactile user inputs into digital information, and depending upon software and lesson instructions contained on the floppy diskettes, transmits the appropriate responses in the form of textural and image information on the CRT displays. The system also includes a detachable keyboard and printer terminal 20 which allows an instructor to author new software and lessonware or to change existing software and lessonware. <IMAGE></p> |
