Title (EN) TOUCH-SENSITIVE SURFACE
(FR) SURFACE TACTILE
Abstract: front page image
(EN)A body part of a user touching a touch sensitive surface is determined based on a measured electrostatic signal (540, 550). The electrostatic signal is transmitted by a transmitter (520) and received by a receiver (530) using a capacitively coupled human body as a communication channel. A touch signal is provided by the touch sensitive surface being touched by the user. The received electrostatic signal is measured (540, 550) in response to the touch signal and the body part of the user touching the touch sensitive surface is determined (560, 570).
(FR)Une partie de corps d'un utilisateur touchant une surface tactile est déterminée sur la base d'un signal électrostatique mesuré (540, 550). Le signal électrostatique est transmis par un émetteur (520) et reçu par un récepteur (530) à l'aide d'un corps humain couplé de manière capacitive en tant que canal de communication. Un signal tactile est fourni par la surface tactile qui est touchée par l'utilisateur. Le signal électrostatique reçu est mesuré (540, 550) en réponse au signal tactile et la partie de corps de l'utilisateur touchant la surface tactile est déterminée (560, 570).
