DISPOSITIF DE COMMANDE D'UN SYSTEME INFORMATIQUE |
摘要 |
<p>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 color. The inventive device is particularly designed for collective initiation to microcomputing and collective training in using software.</p> |
