Abstract

L'invention concerne un procédé et un appareil permettant de capter, de coder et de transmettre les données d'un clavier électronique, les signaux de commande d'un dispositif de pointage, ainsi que des entrées vocales. L'appareil comprend un dispositif sans fil (11) attaché par exemple à chaque poignet de l'utilisateur. Ce dispositif sans fil (11) utilise une matrice de réflectance optique qui détecte toute frappe sur le clavier, un capteur d'inertie qui code les commandes du dispositif de pointage, et un circuit d'acquisition sonore, dont tous les signaux sont éventuellement multiplexés et diffusés, par exemple par fréquence radioélectrique ou sans fil, jusqu'à une station de base locale (13) reliée au système informatique hôte (14). La matrice de réflectance optique comprend plusieurs diodes électroluminescentes à infrarouge (16), ou d'autres sources lumineuses, qui éclairent séquentiellement les colonnes d'un plan situé sous la paume de l'utilisateur, les reflets des doigts de cet utilisateur étant détectés par rangées au moyen de plusieurs capteurs tels que des phototransistors (17). Les doigts dudit utilisateur (ou toute autre obstruction) pénètrent dans le plan optique, en simulant dans l'air une action de frappe sur le clavier. Le mouvement de la main est capté au moyen de deux accéléromètres dimensionnels, et codé afin de produire un signal de commande de dispositif de pointage. Un système audio incorporé permet éventuellement d'acquérir des signaux acoustiques, ce système fournissant également un retour sonore transmis depuis la station de base (13), pour des intercommunications vocales et pour confirmer l'entrée desdits signaux.
