Title
(EN) ELECTROSTATIC STYLUS
(FR) STYLET ÉLECTROSTATIQUE
Abstract
(EN) A handheld, stylus-type input device for interfacing with a touch screen having an array of sensor nodes (e.g., a capacitive touch screen) may include a handheld body having a first end, a tip at the first end, an electrode arranged at least partially within the body, and a circuit configured to produce an electrical potential on the electrode to generate an electric field proximate the stylus tip. When the stylus tip is placed in contact with the touch screen, the electric field activates one or more sensor nodes outside of a physical contact area between the tip and the touch screen, producing an effect on the sensor nodes similar to that of a finger or other object having a larger contact area with the touch screen than the stylus, thus providing activation of the touch screen while providing better view of the screen near the point of contact.
(FR) L'invention concerne un dispositif d'entrée de type stylet portatif destiné à s'interfacer avec un écran tactile possédant un réseau de nœuds de capteurs (par exemple, un écran tactile capacitif), qui peut comprendre un corps portatif ayant une première extrémité, une pointe au niveau de la première extrémité, une électrode agencée au moins partiellement à l'intérieur du corps, et un circuit configuré pour produire un potentiel électrique sur l'électrode afin de générer un champ électrique à proximité de la pointe du stylet. Lorsque la pointe du stylet est mise en contact avec l'écran tactile, le champ électrique active un ou plusieurs nœuds de capteurs à l'extérieur d'une zone de contact physique entre la pointe et l'écran tactile, produisant un effet sur les nœuds de capteurs similaire à celui d'un doigt ou d'un autre objet ayant une surface de contact avec l'écran tactile plus grande que le stylet, permettant ainsi l'activation de l'écran tactile tout en offrant une meilleure vue de l'écran à proximité du point de contact.
