Abstract
A computing device receives electronic data generated by a touch-sensitive surface in response to a contact made with the touch-sensitive surface, and a tilt sensor detects a tilt angle of the touch-sensitive surface. The tilt angle is indicative of an angular displacement between a reference plane defined by the touch-sensitive surface in a reference position and a current plane defined by the touch-sensitive surface in a current position. A parameter or other aspect of an automated contact discriminating process is modified based at least in part on the detected tilt angle of the touch-sensitive surface. The contact discriminating process determines whether the contact made with the touch-sensitive surface is intentional or not intentional. In response to determining that the contact is intentional, the electronic data is accepted as valid input for further processing. In response to determining that the contact is not intentional, the electronic data is rejected for further processing.
