Title (EN) PEN LOCATION DETECTION
(FR) DÉTECTION D'EMPLACEMENT DE STYLO
Abstract:
(EN) A method including receiving an output signal from a grid based digitizer sensor to detect outputs from junctions of the sensor, identifying, based on the output signal, an area on the sensor likely to include output caused by touch of a passive pen tip, applying a maximum likelihood cost function at points within the area to identify likely coordinates of the passive tip on the digitizer sensor, and selecting most likely coordinates for the location of the passive pen tip, wherein the most likely coordinates are defined based on the output signal in the area and on a pre-defined response function, wherein the response function relates an output signal from a junction to distance of the passive tip from the junction. Related apparatus and methods are also described.
(FR) La présente invention concerne un procédé comprenant la réception d'un signal de sortie à partir d'un capteur de numériseur basé sur une grille pour détecter les sorties à partir des jonctions du capteur, l'identification, basée sur le signal de sortie, d'une zone sur le capteur susceptible de comprendre la sortie provoquée par le toucher d'une pointe de stylo passive, l'application d'une fonction de coût de probabilité maximale à des points à l'intérieur de la zone à identifier des coordonnées les plus probables de la pointe passive sur le capteur de numériseur et la sélection des coordonnées les plus probables destinées à l'emplacement de la pointe du stylo passive, les coordonnées les plus probables étant définies sur la base de la sortie du signal dans la zone et d'une fonction de réponse prédéfinie, la fonction de réponse reliant un signal de sortie à partir d'une jonction à la distance de la pointe passive à partir de la jonction. L'invention concerne également un appareil et des procédés s'y rapportant.
