Abstract

The system will analyze the location where contact is being made by a user on the touchpad surface, wherein the contact must be an area gesture defined as a gesture in a specific area of the touchpad along with contact that is either a single contact that is larger than a typical finger or is made by multiple contacts, wherein data from the touchpad is ignored when the area of contact begins or is only made within a corner, side, top or other region or combination of regions, wherein if an area gesture has some contact with the region, the area gesture is considered suspect and may be ignored as accidental or unintended contact.

Claims

1. A method for reducing unintended input when an area gesture is initiated on a touch sensitive surface, said method comprising the steps of:

1) determining if an area gesture has been initiated;

2) determining if the area gesture was initiated within an area gesture limiting zone; and

3) ignoring the area gesture if the area gesture was initiated within the area gesture limiting zone.

2. A method for reducing unintended input when an area gesture is initiated on a touch sensitive surface, said method comprising the steps of:

1) determining if an area gesture has been initiated;

2) determining if the area gesture was initiated within an area gesture limiting zone;

3) analyzing the area gesture if the area gesture was initiated within the area gesture limiting zone in order to determine if the area gesture is valid; and

4) accepting the area gesture as valid if the area gesture is determined to be valid, and ignoring the area gesture if it is determined to be invalid.
