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.
