Abstract:
1. An apparatus, comprising: a first slave controller coupled to a first capacitive touch panel comprising a first plurality of sensor elements, wherein the first slave controller is configured to: the master controller, coupled with the first slave controller and configured to receive the first set of capacitance values and to calculate the first centroid position of the contact based on the first set of capacitance values measured from the first capacitive touch panel and a second set of capacitance values measured from a second capacitive touch panel, wherein a space between the two capacitive touch panels is small enough such that the contact at a single location can affect capacitance values for both panels simultaneously, wherein the first and the second sets of capacitance values are measured while the contact is simultaneously affecting capacitance values for both panels, and wherein the first edge of the first capacitive touch panel is adjacent to a second edge of the second capacitive touch panel.
