US 2025/0053263 A1 · TOUCH PANEL MISTOUCH RECOGNITION

Abstract

An example gesture detection method includes detecting at a first time a first touch on a touch panel, where the first touch covers a first area of the touch panel, and then determining whether the first touch is within a track region that surrounds a fingerprint sensing region. The method includes determining whether the first touch is within the fingerprint sensing region, the fingerprint sensing region including a sensing surface of a fingerprint sensor. The method includes 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 is a majority of the fingerprint sensing region. The method includes 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, where the second threshold is a fraction indicative of a majority of an area associated with the corresponding touch. The method includes based on determining that the second fraction exceeds the second threshold, determining whether the first touch is valid.
