Title (EN) MULTITOUCH INPUT TO TOUCHPAD DERIVED FROM POSITIVE SLOPE DETECTION DATA
(FR) ENTRÉES TACTILES MULTIPLES SUR UN PAVÉ NUMÉRIQUE DÉDUITES À PARTIR DE DONNÉES DE DÉTECTION DE PENTES POSITIVES
Abstract:
(EN) A method for using existing touchpad hardware to detect and track multiple objects such as fingers that are in contact with a touchpad, wherein the method extracts information from data that is already being collected, wherein analysis of the data is simplified by identifying objects by only looking for a positive slopes and negative slopes to identify multiple objects in data from the touchpad.
(FR) L'invention concerne un procédé pour utiliser un matériel de pavé tactile existant dans le but de détecter et de repérer des objets multiples tels que des doigts qui sont en contact avec un pavé tactile. Le procédé extrait des informations à partir de données qui sont déjà recueillies. L'analyse des données est simplifiée par l'identification des objets en recherchant seulement des pentes positives et des pentes négatives pour identifier des objets multiples dans des données à partir du pavé tactile.
