Abstract
A system may have a touch controller, a gesture detection device, and a capacitive sensor having at least one first and at least one second electrode, wherein the at least one first electrode is coupled with a controllable generator for supplying an AC signal to the first electrode. Furthermore, a configurable coupling is provided between the at least one second electrode, an input of the touch controller and an input of the gesture detection device, wherein the coupling can be configured to allow the system to perform a touch detection from signals received from the second electrode by the touch controller in a first configuration mode and to perform a gesture detection from signals received from the second electrode by the gesture detection device in a second configuration mode.
