Abstract: A game controller with a communications interface includes a touch sensitive pad having a plurality of touch sensitive elements, and processing circuitry coupled to the communications interface and the at least one touch sensitive pad. The processing circuitry enacts touch pad configuration settings that correlate subsets of the plurality of touch sensitive elements to produce distinct user input locations. The processing circuitry receives touch pad input from the at least one touch sensitive pad. The processing circuitry processes the touch pad input to determine user input directions based upon the touch pad configuration settings, and then transmits the touch pad input directions via the communications interface for use as gaming input.

Abstract: Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.

Abstract: Control circuitry for a touch panel includes a touch panel interface, a memory comprising scanning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the scanning logic is executed, to energize a first and a second row in the touch panel simultaneously, a first time; obtain a first signal measurement along a column intersecting the first and second rows; energize the first and the second row in the touch panel simultaneously, a second time; obtain a second signal measurement along the column; and determine a first pixel value and a second pixel value along the column from the first signal measurement and the second signal measurement.
