Abstract: A system can include an input for receiving objects having a flat shape; a capacitance sensing network comprising a plurality of capacitance sensors positioned to be proximate to the received objects; an operations section coupled to the capacitance sensing network and configured to perform predetermined operations on the objects; and a processor section coupled to receive capacitance sense values from the capacitance sensors and configured to determine the presence and features of received objects, prior to the objects being forwarded to the operations section.

Abstract: An apparatus and method for identifying gestures performed on a touch-sensing surface. In one embodiment, a gesture recognition unit processes an input signal to determine input metrics associated with contacts at the touch-sensing surface. The gesture recognition unit identifies a gesture based on comparing at least one of the input metrics with a threshold value associated with the gesture.

Abstract: A computing system includes a sensor configured to detect user inputs. The system further includes a processor configured to receive a detected first user input from the sensor. The processor further receives a detected second user input from the sensor. In response, the processor assigns a command to the first user input based on the second user input.

Abstract: A non-planar touch sensor pad is described.

Abstract: A touch sensor pad having polygon shaped sensor elements of five or more sides is described.
