DEVICE AND METHOD FOR CONTROL INTERFACE SENSITIVE TO A MOVEMENT OF A BODY OR OF AN OBJECT AND CONTROL EQUIPMENT INTEGRATING THIS DEVICE
First Claim
1. A device for control interface sensitive to a movement of a body or of an object, comprising:
- a detection surface,at least one capacitive sensor, said sensor(s) each comprising a measurement electrode including an active surface facing the detection surface, or substantially coinciding with said detection surface,a guard of electrically conducting material disposed in proximity to the measurement electrodes at least along their face substantially opposite to the active surface, which guard is excited at an alternating (AC) electrical potential substantially identical to that of the measurement electrodes,electronic means for exciting the measurement electrodes and processing the signals emanating from said capacitive sensors, so as to provide distance information between the active surface of the electrodes and said object,the active surfaces of the measurement electrodes are independent of one another, andthe electronic means of excitation and processing are further arranged to interrogate said measurement electrodes independently of one another.

Abstract
A method and device is provided for control interface sensitive to a movement of a body or of an object and the control equipment integrating this device, in particular gestural and/or tactile and/or vocal, sensitive to a movement of at least one part of a body or of an object within a detection space, including a detection surface, at least one capacitive sensor, having a measurement electrode, a guard made of electrically conducting material disposed in proximity to the measurement electrodes, and electronic apparatus for processing the signals emanating from the at least one capacitive sensor. The active surfaces of the measurement electrodes are independent of one another, and an electronic device for excitation and processing interrogate these measurement electrodes independently of one another.
