Unintentional touch rejection
First Claim
1. 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 and at least one other characteristic of the touch, 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.

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.

8. 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 a proximity of a first location of the first touch and second location of 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, communicate an input associated with the touch to an application. - View Dependent Claims (9, 10, 11, 12, 13)

14. A computer storage device not consisting of a carrier wave and 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 and at least one other characteristic of the touch, 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 (15, 16, 17, 18, 19, 20)
