CA 2522604

A data input system having a keypad defining a plurality of keys, each key contains at least one symbol of a group of symbols. The group of symbols is divided into subgroups each having at least one of alphabetical symbols, numeric symbols, and command symbols, where each subgroup is associated with at least a portion of a user's finger. A finger recognition system is in communication with at least one key, where the key has at least a first symbol from a first subgroup and at least a second symbol from a second subgroup, The finger recognition system is configured to recognize the portion of the user's finger when the finger interacts with the key so as to select the symbol on the key, corresponding to the subgroup associated with the portion of the user's finger.

Cette invention concerne un système d'entrée de données dont le clavier (3300) définit une pluralité de touches (3301-3309) contenant chacune au moins un symbole pris dans un groupe de symboles. Le groupe de symboles est subdivisé en sous-groupes comprenant chacun au moins l'un des symboles alphabétiques, l'un des symboles numériques et l'un des symboles de commande, chaque sous-groupe étant associé à au moins une partie de doigt de l'utilisateur. Le système de reconnaissance tactile est en communication avec au moins une touche, laquelle touche porte au moins un premier symbole du premier sous-groupe et un deuxième symbole du deuxième sous-groupe. Le système de reconnaissance tactile est conçu pour reconnaître la partie du doigt lorsque ce dernier interagit avec la touche de manière à sélectionner sur la touche le symbole correspondant au sous-groupe associé à cette partie du doigt.
