Abstract
A method of indicating a gesture proximate a touch-sensor pad is provided. In one embodiment, the method comprises detecting a first presence of a conductive object proximate to the touch-sensor pad, and initiating a gesture signal if the first presence lasts a first duration of time that is less than a first reference amount of time. In this embodiment, the method further comprises detecting a second presence occurring a first elapsed time after an end of the first presence, and terminating the gesture signal if the first elapsed time is greater than a second reference amount of time, otherwise maintaining the gesture signal at least until an end of the first elapsed time and at least until an occurrence of a terminating event. This and other embodiments can be used to initiate virtual-button signals in response to specific gestures by the user.
