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.

2. A method comprising:
-
receiving a touch on a touch-sensitive display of a device; calculating a function based on an acceleration of the touch; based at least in part on the calculated function, determining a probability that the touch is intentional; and based at least in part on the determined probability indicating that the touch is an intentional touch, communicating an input associated with the touch to an application. - View Dependent Claims (3, 4, 5, 6, 7)

9. A computing device comprising:
-
at least one processing unit; and at least one memory storing computer readable instructions that when executed by the at least one processing unit cause the computing device to; receive a first touch on a touch-sensitive display of a device; receive at least a second touch at substantially the same time; based at least in part on the first touch and the second touch determine a probability that the first touch is intentional; and based at least in part on the determined probability indicating that the first touch is an intentional touch, communicating an input associated with the touch to an application. - View Dependent Claims (10, 11, 12, 13, 14)

15. A computer storage device comprising computer readable instructions that when executed by a processing unit cause a computing device to perform a method, the method comprising:
-
receiving a touch on a touch-sensitive display of a device; determining a time period over which the touch is received; based at least in part on the time period, determining a probability that the touch is intentional; and based at least in part on the determined probability indicating that the touch is an intentional touch, communicating an input associated with the touch to an application. - View Dependent Claims (16, 17, 18, 19, 20, 21)
