Object position detector with edge motion feature and gesture recognition
First Claim
1. A method for responding to a plurality of presences of an object proximate to a touch-sensor pad, wherein said plurality of presences includes a first presence and a second presence, said first presence lasting a first duration of time and said second presence occurring a first elapsed time after an end of said first presence and lasting a second duration of time, the method comprising:
- initiating a gesture signal if said first duration of time is less than a first reference amount of time;
terminating said gesture signal after said end of said first presence if said first elapsed time is greater than a second reference amount of time;
terminating said gesture signal and initiating and terminating a second gesture signal after an end of said second presence if said first elapsed time is less than said second reference amount of time and if said second duration of time is less than said third reference amount of time; and
terminating said gesture signal after said end of said second presence if said first elapsed time is less than said second reference amount of time and if said second duration is greater than said third reference amount of time.

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.

7. A method for indicating a gesture proximate to a touch-sensor pad, the method comprising:
-
detecting a first presence of a conductive object proximate to said touch-sensor pad in one of a plurality of predefined regions of said touch-sensor pad, said first presence lasting a first duration of time; providing a gesture signal if said first duration of time is less than a first reference amount of time, wherein said gesture signal is of a first type if said first presence is in a first one of said plurality of predefined regions and wherein said gesture signal is of a second type different from said first type if said first presence is in a second one of said plurality of predefined regions.

8. A method for indicating a gesture proximate to a touch-sensor pad, the method comprising:
-
detecting a first presence of a conductive object proximate to said touch-sensor pad, said first presence lasting a first duration of time; initiating a gesture signal if said first duration of time is less than a first reference amount of time; detecting a second presence of said conductive object proximate to said touch-sensor pad, said second presence occurring a first elapsed time after an end of said first presence; terminating said gesture signal if said first elapsed time is greater than a second reference amount of time, otherwise maintaining said gesture signal at least until an end of said first elapsed time and at least until an occurrence of a terminating event. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
