1. A gesture detection method comprising:
detecting at a first time a first touch on a touch panel, the first touch covering a first area of the touch panel;
determining whether the first touch is within a track region that surrounds a fingerprint sensing region;
in response to determining that the first touch is within the track region, determining whether the first touch is within the fingerprint sensing region, the fingerprint sensing region comprising a sensing surface of a fingerprint sensor;
in response to determining that the first touch is within the fingerprint sensing region, determining a first fraction of the fingerprint sensing region covered by the first touch and determining whether the first fraction exceeds a first threshold, the first threshold being a majority of the fingerprint sensing region;
in response to determining that the first fraction exceeds the first threshold, determining a second fraction of all of the first area that is within the fingerprint sensing region and determining whether the second fraction exceeds a second threshold, the second threshold being a fraction indicative of a majority of an area associated with the corresponding touch; and
based on determining that the second fraction exceeds the second threshold, determining whether the first touch is valid.
