Touch button false activation suppression
First Claim
1. A touch member comprisinga touch surface comprising at least two electrodes that are separated from each other on the touch surface, each of the electrodes having a certain signal level threshold in order to activate the touch member, anda first area and a second area within the touch surface, wherein the at least two electrodes, upon touching the touch member in an unlocked state, are arranged tomeasure periodically a signal level received from each of the electrodes to indicate a touch location,report periodically the touch location with respect to the first area of the touch surface,report the measured signal level of each of the electrodes in the second area of the touch surface, andreceive instruction to select an operation state of the touch member based on calculated touch location information of the reported touch location and compared signal level information of the reported measured signal level.

Abstract
A touch member (210) comprises a touch surface (20, 30) having at least two sensor electrodes (21-23) that are separated from each other on the touch surface (20, 30). Each of the sensor electrodes (21-23) have a certain signal level threshold with relation to activate/lock the touch member (210). The touch surface (20, 30) is divided into a first area and a second area each comprising at least one of the sensor electrodes (21-23). Upon touching the touch member (210) in an unlocked state, the at least two electrodes (21-23) are arranged to measure periodically a signal level received from each of the electrodes (21-23) to indicate a touch location, report periodically the touch location with respect to the first area of the touch surface (20, 30), and report the measured signal level of each of the electrodes (21-23) in the second area of the touch surface (20, 30). The controller (214) sends an instruction to select an operation state of the touch member (210) based on calculated touch location information of the reported touch location and compared signal level information of the reported measured signal level.

20. A method comprising
defining a certain signal level threshold to each of at least two electrodes separated from each other on a touch surface, the signal level threshold relating to activate the electrode, upon touching the touch surface in an unlocked state, measuring a signal level from each of the at least two electrodes to indicate a touch location on the touch surface, reporting periodically the touch location with respect to a first area of the touch surface, reporting the measured signal level of each of the electrodes in a second area of the touch surface that excludes the first area, calculating a change of the touch location based on the reported touch location to produce location information, comparing the reported measured signal level to the signal level threshold of the corresponding electrode to produce signal level information, and selecting an operation state of a touch member based on location information and signal level information.
