1. A method for responding to a multiple-presence gesture using a touch-sensor, the method comprising:
- detecting a first presence of an object proximate to the touch-sensor;
detecting a second presence of an object proximate to the touch-sensor, the second presence starting after a beginning of the first presence and overlapping in time with, the first presence; and
initiating a gesture signal indicating the occurrence of a multiple-presence gesture responsive to each of a set of criteria being met, the set of criteria comprising the second presence starting after a beginning of the second presence and overlapping in time with, the first presence.

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.

13. A touch-sensor comprising:
-
a substrate;
a plurality of sensor electrodes disposed on the substrate, the plurality of sensor electrodes configured to sense an object proximate to the plurality of sensor electrodes, a processor coupled to the plurality of sensor electrodes, the processor configured to;
detect a first presence of an object proximate to the touch-sensor;
detect a second presence of an object proximate to the touch-sensor, the second presence starting after, and overlapping in time with, the first presence; and
initiate a gesture signal indicating the occurrence of a multiple-presence gesture responsive to a set of criteria being met, the set of criteria comprising detecting first and second presences of objects, where the second presence starts after, and overlaps in time with, the first presence. from a first time associated with a first Z value is on one side of a first threshold until a second time later than the first associated with a second Z value is on an opposite side of the first threshold, wherein all Z values associated with times between the first time and second time are all past a reference Z value, provide positional information representing motion of the object on the touch-sensor; and
after the second time where the second Z value is on the opposite side of the first threshold, initiate a gesture signal indicating the occurrence of the gesture. - View Dependent Claims (14, 15)

16. A touch-sensor for responding to a gesture, the touch-sensor comprising:
-
a substrate;
a plurality of sensor electrodes disposed on the substrate, the plurality of sensor electrodes configured to sense an object proximate to the plurality of sensor electrodes, a processor coupled to the plurality of sensor electrodes, the processor configured to;
detect a first presence of an object proximate to the touch-sensor, the first presence lasting a first duration of time;
initiate a gesture signal if a set of criteria is met, the set of criteria comprising the first duration of time being less than a first reference amount of time;
detect a second presence of the object proximate to the touch-sensor, the second presence occurring a first elapsed time after an end of the first presence; and
terminate 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. - View Dependent Claims (17, 18, 19, 20, 21, 22)
