Abstract
An electronic device and method may provide accurate touch input recognition in a touch key area with high sensitivity while preventing false inputs from proximate touches. The method may involve recognizing a first signal and a second signal detected by an input on the touch key area; and processing the input on the touch key area based on at least a comparison result of the first signal and the second signal. The first and second signals may be indicative of capacitance changes occurring at different locations within the touch key area.
Claims20
An electronic device comprising:
- a housing including a first surface;
- a touch key area disposed at a portion of the first surface;
- an integrated circuit configured to detect an input through the touch key area;
- a processor electrically connected to the integrated circuit;
- and
- first, second and third conductive lines separated from one another and each connected between the touch key area and the integrated circuit,
- wherein the first conductive line is a transmit channel line connected at a first point on the touch key area, the second conductive line is a first reception channel line providing a first signal indicative of a first change in capacitance, due to at least one external object, between conductive elements at a first location within the touch key area, and the third conductive line is a second reception channel line providing a second signal indicative of a second change in capacitance, due to the at least one external object, between conductive elements at a second location within the touch key area.
