Title (EN) A MULTIPURPOSE OPTICAL INTELLIGENT KEY BOARD APPARATUS
(FR) APPAREIL A CLAVIER INTELLIGENT, OPTIQUE ET POLYVALENT
Abstract:
(EN) A multipurpose optical intelligent key board apparatus (100) permits a plurality of key tops (104) made of transparent materials in an optical dot matrix arrangement to be moved upward and downward. It forces the corresponding positions of the optical dot matrix to be turned on or off, so that a computer or an electronic appliance can be operated by the predetermined key inputs. Therefore, the function command words and characters appearing on the key tops is displayed by a display device (112) supported by its software.
(FR) Appareil (100) à clavier intelligent, optique et polyvalent permettant à une pluralité de touches (104) constituées de matériaux transparents et disposés en matrice de points optique de se déplacer dans le sens vertical. Il oblige les positions correspondantes de la matrice de points optique de se mettre en état de marche ou en état d'arrêt de sorte que l'on puisse commander un ordinateur ou un appareil électronique à l'aide des entrées de touches prédéterminées. Ainsi, les mots et caractères de commande de fonction présentés sur les touches sont affichés par un dispositif d'affichage (112) assisté par son logiciel.
