摘要：A touch member () comprises a touch surface () having at least two sensorelectrodes (-) that are separated from each other on the touch surface (). Each of thesensor electrodes (-) have a certain signal level threshold with relation to activate/lock

the touch member (). The touch surface () is divided into a first area and a second areaeach comprising at least one of the sensor electrodes (-). Upon touching the touchmember () in an unlocked state, the at least two electrodes (-) are arranged to measureperiodically a signal level received from each of the electrodes (-) to indicate a touchlocation, report periodically the touch location with respect to the first area of the touchsurface (), and report the measured signal level of each of the electrodes (-) in thesecond area of the touch surface (). The controller () sends an instruction to select anoperation state of the touch member () based on calculated touch location informationof the reported touch location and compared signal level information of the reportedmeasured signal level.
