Title (EN) CAPACITIVE MOUSE
(FR) SOURIS CAPACITIVE
Abstract:
(EN) A pointing device some or all of whose elements are made from capacitive sensors. Such elements may include a rotary motion detector (310) which includes a rotating member (306) and a plurality of fixed capacitive detecting members (322 and 320); a rolling ball (602) with patterned conductive surface (604) and a plurality of fixed capacitive detecting members (608); capacitive touch sensors or capacitive switches to serve as mouse buttons (822); and a scrolling wheel (902), knob (1002), or touch surface built from capacitive sensors (1106). The pointing device further includes a capacitance measuring circuit (1704) and processor (1702) to measure variations of capacitance on the various capacitive elements and to determine the movement of and other activations of the mouse.
(FR) L'invention concerne un dispositif pointeur dont quelques éléments ou tous sont réalisés à partir de capteurs capacitifs. De tels éléments peuvent comprendre un détecteur de mouvement rotatif (310), lequel comporte un élément rotatif (306) ainsi que plusieurs éléments capacitifs (322 and 320), fixes, de détection, une bille de roulement (602) dotée d'une surface conductrice à motif (604), ainsi que plusieurs éléments capacitifs (608), fixes, de détection, des capteurs tactiles ou commutateurs capacitifs, utiles en tant que boutons de la souris (822), ainsi qu'une roulette (902) ou un bouton de défilement (1002), ou une surface tactile de défilement construite à partir de capteurs capacitifs (1106). Ce dispositif pointeur comprend en outre un circuit de mesure de capacité (1704) ainsi qu'un processeur (1702) conçu pour mesurer des variations se produisant dans la capacité des divers éléments capacitifs, et pour déterminer le déplacement de la souris ou d'autres fonctionnements de celle-ci.
