Abstract
A touch-sensitive position sensor is disclosed. The sensor comprises an array of first electrodes and an array of second electrodes arranged in a pattern to provide a sensing surface, wherein at least some of the first electrodes and the second electrodes are arranged to follow paths which are non-linear within the sensing surface such that there are ends of the first electrodes and ends of the second electrodes which meet a common edge of the sensing surface. A controller is coupled to respective ones of the first electrodes and the second electrodes and arranged to determine a reported position for an object adjacent the sensing surface by measuring changes in an electrical parameter e.g. capacitance or resistance, associated with the first electrodes and the second electrodes which is caused by the presence of the object. The controller is further operable to provide an indication of the reported position in a first coordinate system defined relative to the first electrodes and the second electrodes, the sensor further comprises a processor arranged to receive the indication of reported position from the controller in the first coordinate system and to transform the reported position to an output position in a second coordinate system, wherein the transform is based on the non-linear pattern of electrodes. Thus, a sensor having electrodes which are distorted so as to meet a common edge may be provided for ease of connectability, with the distortion been accounted for through the transform performed by the processor.
