Title (EN) INCREASING LOW-FORCE ACCURACY AT A DEVICE
(FR) AUGMENTATION DE LA PRÉCISION À FAIBLE FORCE AU NIVEAU D'UN DISPOSITIF
Abstract:
(EN) Methods and devices are disclosed for increasing low-force accuracy at a device, such as a pen or a stylus which are used for communicating with a digitizer. An example method describes detecting an amount of force at the tip of the device and generating a voltage associated with the amount of force. The example method further includes logarithmically sampling the voltage to produce a digital value associated with the amount of force and determining whether the device is operating in an inking state based on the digital value. An example device may include a pressure sensor to detect an amount of force and generate a voltage associated with the amount of force, a sampling circuit to sample the voltage to produce a digital value, a memory and a processor in communication with the memory to determine whether the device is operating in an inking state based on the digital value.
(FR) L'invention concerne des procédés et des dispositifs permettant d'augmenter la précision à faible force au niveau d'un dispositif, tel qu'un stylo ou un stylet qui sont utilisés pour communiquer avec un numériseur. Un procédé illustratif décrit la détection d'une quantité de force au niveau de la pointe du dispositif et la production d'une tension associée à la quantité de force. Le procédé illustratif consiste en outre à échantillonner de manière logarithmique la tension pour produire une valeur numérique associée à la quantité de force et à déterminer si le dispositif fonctionne dans un état d'encrage en fonction de la valeur numérique. Un dispositif illustratif peut contenir un capteur de pression destiné à détecter une quantité de force et produire une tension associée à la quantité de force, un circuit d'échantillonnage destiné à échantillonner la tension pour produire une valeur numérique, une mémoire et un processeur en communication avec la mémoire destinés à déterminer si le dispositif fonctionne dans un état d'encrage en fonction de la valeur numérique.
