Abstract: Methods and devices are disclosed for determining that a touch gesture is validly detected. In one embodiment, a method for detecting the touch gesture comprises: generating by a first sensing unit a first sensing parameter upon a touch action on the touch input interface; determining by the first sensing unit a first touch gesture corresponding to the first sensing parameter; acquiring by the first sensing unit a second touch gesture corresponding to a second sensing parameter generated by a second sensing unit; and determining that the touch gesture has been detected and is valid by confirming that the first touch gesture and the second touch gesture are the same; wherein the first and second sensing units are interconnected and are respectively one and the other of a touch control processor for the touch input interface and a motion sensor. With the combination of two sensors and checking the correspondence between touch gestures detected by the two sensors, the accuracy of detecting a valid touch gesture may be improved.
