1. A method for indicating a gesture proximate to a touch-sensor, the method comprising:
- detecting a first presence of a conductive object proximate to said touch-sensor in one of a plurality of predefined regions of said touch-sensor, 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

Abstract
A method of generating a signal comprising providing a capacitive touch sensor pad including a matrix of X and Y conductors, developing capacitance profiles in one of an X direction and a Y direction from the matrix of X and Y conductors, determining an occurrence of a single gesture through an examination of the capacitance profiles, the single gesture including an application of at least two objects on the capacitive touch sensor pad, and generating a signal indicating the occurrence of the single gesture.

9. A method for indicating a gesture proximate to a touch-sensor, the method comprising:
-
detecting a first presence of a conductive object proximate to said touch-sensor, 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, said second presence occurring a first elapsed time after an end of said first presence and lasting a second duration;
terminating said gesture signal if said first elapsed time is greater than a second reference amount of time, otherwise terminating said gesture signal and initiating and terminating a second gesture signal if said first elapsed time is less than said second reference amount of time and if said second duration is less than a third reference amount of time. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for responding to a plurality of presences of an object proximate to a touch-sensor, 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, said 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 a 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. - View Dependent Claims (16, 17, 18, 19, 20)
