METHOD FOR THE ACQUISITION AND ANALYSIS OF A MULTI-CONTACT TACTILE SENSOR USING A DICHOTOMOUS PRINCIPLE, AND ELECTRONIC CIRCUIT AND MULTI-CONTACT TACTILE SENSOR IMPLEMENTING ONE SUCH METHOD

摘要

The invention relates to a method for the acquisition and analysis of a multi-contact tactile sensor including a matrix of capture points and an electronic analysis circuit for controlling the acquisition and analysis of the matrix. The method comprises the following successive steps, namely a step (24, 25) comprising the acquisition of a sensor detection zone in order to determine the state of each of the contact points of the detection zone and a step (26) comprising the analysis of said detection zone in order to deliver information as a function of the activation state of the contact points. The acquisition step (24, 25) and the analysis step (26) are repeated iteratively. The acquisition step (24, 25) is performed on a detection zone containing the activated contact points determined during the preceding analysis step (26). The detection zone is smaller than the detection zone acquired during the preceding acquisition step (24, 25). The iteration is performed until a pre-determined spatial resolution is obtained (27). The invention also relates to an electronic acquisition and analysis circuit and a multi-contact tactile sensor implementing one such method.
