Abstract
The device in accordance with the invention includes a series of detection areas (2) on the touch-sensitive pad, an analog circuit for applying a detection coefficient to each detection area (2), which coefficient corresponds to the degree the detection area is overlapped by the control member, and determines a median point of the detection areas as weighted by their respective detection coefficients.
