Abstract
A sensor arrangement for capacitive touch and non-touch detection, has a transmission electrode and a predefined number of receiving electrodes coupled with an evaluation unit, wherein the evaluation unit operates in a non-touch detection mode and in a touch detection mode, wherein the transmission electrode generates an alternating electric near field, and wherein in the non-touch detection mode, the evaluation unit evaluates signals from the receiving electrodes to determine a three-dimensional position of an object; and in the touch detection mode a surface touch detection area defined by the predefined number of electrodes is divided into a plurality of segments wherein within each segment at least two electrodes of the predefined number of electrodes contribute with a portion of their electrode surface area such that different electrode surface area ratios are formed for each of the plurality of segments.
