Abstract:
1. System for generating input signals correlating with manual input operations executed by a user, comprising: an electrode group comprising a generator electrode and a plurality of receiving electrodes integrated into an equipment component, wherein the generator electrode and the plurality of receiving electrodes are formed by flat shaped electrodes and at least a subset of the receiving electrodes are arranged in a plane, and a circuit arrangement coupled with the electrodes of the electrode group, wherein the electrode group and the circuit arrangement constitute a sensor circuit which allows both, a detection of a proximity status of a hand or a finger of the user to evaluate a physical contacting of the equipment component, and also a detection of a non-touching gesture performed by the hand or the finger of the user in an area which is spatially located in front of the equipment component, wherein the circuit arrangement is configured to discriminate between a touch event and a gesture event by evaluating signals received from the receiving electrodes, wherein the circuit arrangement uses a first threshold with respect to a signal amplitude and a second threshold with respect to a derivative of the signal amplitude with time to discriminate the gesture event and the touch event.
