Abstract
According to one embodiment of the present disclosure, a touch controller is adapted to be coupled to a touch screen and to a motion sensor. The touch controller is operable in response to a signal from the motion sensor indicating a first motion to switch from a hover event sensing mode of operation to a gesture event sensing mode of operation. In one embodiment, the touch controller is operable in the hover event sensing mode of operation to detect a first hover event and is thereafter operable, in response to the signal from the motion sensor indicating a first motion has occurred, to switch to the gesture event sensing mode of operation and detect a first gesture event.
