Abstract

A method for determining what input should be accepted by a touch sensor after intentional and accidental lift-offs and slide-offs occur when gesturing or performing a function on the touch sensor by a finger or multiple fingers.

Claims

1. A method for determining what input to accept by a first touch sensor following a finger slide-off, said method comprising:

1) providing a first touch sensor having an edge around a perimeter thereof;

2) performing a function or gesture with at least one finger on the first touch sensor and then detecting a finger slide-off of a finger from the first touch sensor;

3) starting a countdown timer upon detecting the finger slide-off, the countdown timer having a predetermined length of time;

4) determining a location of the finger on the first touch sensor when the finger slide-off occurs, the finger slide-off causing a termination of the function or gesture; and

5) allowing the terminated function or gesture to continue when the finger in the finger slide-off slides back onto the first touch sensor within a predetermined distance of the location of the finger slide-off and the countdown timer has not expired, and causing the terminated function or gesture to remain terminated while allowing a new function or gesture to begin when either the finger in the finger slide-off slides back onto the first touch sensor after the countdown timer has expired or the finger in the finger slide-off slides back onto the first touch sensor at a location that is at a distance greater than the predetermined distance.

2. The method as defined in claim 1 wherein the method further comprises allowing adjustment to the predetermined length of time used by the countdown timer in order to affect sensitivity of the method.

3. The method as defined in claim 1 wherein the method further comprises allowing adjustment to the predetermined distance in order to affect sensitivity of the method.

4. A method for determining what input to accept by a first touch sensor following a finger slide-off, said method comprising:

1) providing a first touch sensor having an edge around a perimeter thereof;

2) performing a function or gesture with a plurality of fingers on the first touch sensor at a same time and then detecting a plurality of finger slide-offs of a plurality of fingers from the first touch sensor;

3) starting a countdown timer upon detecting the plurality of finger slide-offs, the countdown timer having a predetermined length of time;

4) determining a location of the plurality of fingers on the first touch sensor when the plurality of finger slide-offs occur, the finger slide-offs causing a termination of the function or gesture; and

5) allowing the terminated function or gesture to continue when the plurality of fingers in the finger slide-offs slide back onto the first touch sensor within a predetermined distance of the respective locations of the finger slide-offs and the countdown timer has not expired, and causing the terminated function or gesture to remain terminated while allowing a new function or gesture to begin when either the plurality of fingers in the finger slide-offs slide back onto the first touch sensor after the countdown timer has expired or the plurality of fingers in the finger slide-offs slide back onto the first touch sensor at respective locations that are at a distance greater than the predetermined distance.

5. The method as defined in claim 4 wherein the method further comprises allowing adjustment to the predetermined length of time used by the countdown timer in order to affect sensitivity of the method.

6. The method as defined in claim 4 wherein the method further comprises allowing adjustment to the predetermined distance in order to affect sensitivity of the method.

7. A method for determining what input to accept by a first touch sensor following a finger slide-off, said method comprising:

1) providing a first touch sensor having an edge around a perimeter thereof;

2) performing a function or gesture with a plurality of fingers on the first touch sensor at a same time, and then detecting a plurality of finger slide-offs of a plurality of fingers from the first touch sensor at opposite sides of the edge of the touch sensor;

3) starting a countdown timer upon detecting the plurality of finger slide-offs, the countdown timer having a predetermined length of time;

4) determining a location of the plurality of fingers on the first touch sensor when the plurality of finger slide-offs occur, the finger slide-offs causing a termination of the function or gesture; and

5) allowing the terminated function or gesture to continue when the plurality of fingers in the finger slide-offs slide back onto the first touch sensor within a predetermined distance of the respective locations of the finger slide-offs and the countdown timer has not expired, and causing the terminated function or gesture to remain terminated while allowing a new function or gesture to begin when either the plurality of fingers in the finger slide-offs slide back onto the first touch sensor after the countdown timer has expired or the plurality of fingers in the finger slide-offs slide back onto the first touch sensor at respective locations that are at a distance greater than the predetermined distance.

8. The method as defined in claim 7 wherein the method further comprises preventing a new function or gesture from beginning when the plurality of fingers in the finger slide-offs slide back onto the first touch sensor when the countdown timer has not expired and the plurality of fingers in the finger slide-offs are within the predetermined distance of the respective locations of the finger slide-offs.
