A method for operating a sensor surface includes detecting an initial position of a stylus relative to the sensor surface, determining initial coordinate values based on the detected initial position of the stylus, and communicating the initial coordinate values for further processing. The method further includes determining subsequent coordinate values based on a subsequent position of the stylus detected after detecting the initial position and, based on a characteristic of the initial or subsequent position detection, modifying the subsequent coordinate values to represent a position that is different than the subsequent position of the stylus. The subsequent coordinate values may be modified to be the same as the initial coordinate values that represent the initial position of the stylus. The modified coordinate values are communicated for further processing. Also disclosed are embodiments of a sensor surface and a computer-readable medium having executable code stored thereon that implement the described methods.

Threshold based coordinate data generation providing tap assist

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.
