Unintentional touch rejection
First Claim
1. A method comprising:
- receiving a touch on a touch-sensitive device;
determining whether the touch exceeds a confidence level;
in response to determining that the touch does not meet the confidence level, determining if the touch exceeds a threshold level; and
in response to determining that the touch exceeds the threshold level, providing a visual feedback on a graphical user interface (GUI).

Abstract
A method for rejecting an unintentional palm touch is disclosed. In at least some embodiments, a touch is detected by a touch-sensitive surface associated with a display. Characteristics of the touch may be used to generate a set of parameters related to the touch. In an embodiment, firmware is used to determine a reliability value for the touch. The reliability value and the location of the touch is provided to a software module. The software module uses the reliability value and an activity context to determine a confidence level of the touch. In an embodiment, the confidence level may include an evaluation of changes in the reliability value over time. If the confidence level for the touch is too low, it may be rejected.

10. A computer readable storage medium including computer executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
receiving a touch input from a touch-sensitive display; determining a confidence level associated with the touch input; determining a predetermined level associated with the confidence level; determining a threshold level associated with the confidence level; and providing a visual feedback on a graphical user interface (GUI) in response to determining that the confidence level is between the predetermined level and the threshold level. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
