Abstract

La présente invention concerne un dispositif de pointage à fonction de défilement à vitesse variable, un procédé de défilement associé et, en particulier, un dispositif compact à fonction de pointage et de défilement pouvant être utilisé dans des dispositifs portables tels que des téléphones mobiles et des PDAs. Le commutateur automatique double mode est, de plus, plus pratique pour l'utilisateur. L'ajout d'une surface amovible formée de motifs optimisés pour la détection par un capteur d'image, à l'intérieur du dispositif, permet de prévenir la dégradation de l'efficacité des capteurs optiques due à la variation des caractéristiques optiques des doigts causée par des changements d'humidité, et la contamination par des corps gras, des saletés, de la lotion, une maladie de peau, etc.. Le dispositif de pointage à défilement à vitesse variable comprend un premier logement définissant la forme extérieure du dispositif de pointage, le déplacement d'une surface d'objet correspondant au mouvement généré par un utilisateur, une structure élastique de restauration de la surface d'objet par élasticité ou magnétisme contre le mouvement de la surface de l'objet, un dispositif destiné à réduire la force de friction par rapport au mouvement bidimensionnel de la structure élastique, un objet réfléchissant comprenant un motif déterminé optimisé pour la détection par le capteur d'image, un capteur tactile destiné à détecter le contact tactile de l'utilisateur, un premier commutateur situé sur un côté d'une partie inférieure du premier logement pour détecter une pression exercée de l'extérieur, et un objet élastique situé d'un côté de la partie inférieure du premier logement pour restaurer la position du premier logement déplacé pour exercer une pression sur le premier commutateur.
