Title
(EN) POSITION, TILT, AND TWIST DETECTION FOR STYLUS
(FR) DÉTECTION DE POSITION, D'INCLINAISON ET DE TORSION POUR STYLET
Abstract
(EN)
A touch-sensitive display device includes a touch sensor having a plurality of display electrodes and control logic coupled to the plurality of display electrodes. The control logic is configured to receive, for each of a plurality of stylus electrodes of an active stylus interacting with the touch-sensitive display device, a spatial capacitance measurement over the touch sensor for that stylus electrode. Relative to the touch sensor, and based on spatial capacitance measurements of the stylus electrodes, the control logic is configured to determine (i) a tip position of the active stylus, (ii) a tilt parameter of the active stylus, and (iii) a twist parameter of the active stylus.

L’invention concerne un dispositif d’affichage tactile comprenant un capteur tactile muni d'une pluralité d’électrodes d'affichage et d'une logique de commande connectée à la pluralité d’électrodes d'affichage. La logique de commande est configurée pour recevoir, pour chacune d'une pluralité d'électrodes de stylet d'un stylet actif qui interagit avec le dispositif d'affichage tactile, une mesure de capacité spatiale sur le capteur tactile pour cette électrode de stylet. Par rapport au capteur tactile, et en se basant sur les mesures de capacité spatiale des électrodes de stylet, la logique de commande est configurée pour déterminer (i) une position de pointe du stylet actif, (ii) un paramètre d'inclinaison du stylet actif et (iii) un paramètre de torsion du stylet actif.
