Title: DEVICE FOR CONTROLLING A COMPUTER SYSTEM
Abstract:
The invention concerns a computer system (1), preferably of the personal microcomputer type, controlled by a group of users by means of several mouse-type pointing devices (3) without wired connection with the system (1). Each pointing device communicates by infrared with a console (38) connected to the system (1) through a communication port (50). A multifrequency transmission technique and a frequency hopping coding are used. The graphic interface of the system is projected (47, 48) on a large screen (49) for collective visual display. The console (38) comprises a detachable receiver horn (41) which enhances the range, and a set of switches (40) for selecting the mouse or mice controlling one or several cursors (54) of different shape and/or colour. The inventive device is particularly designed for collective initiation to microcomputing and collective training in using software.
