摘要： A two-dimensional capacitive sensor device comprises a sensor substrate with a plurality of wedge shaped sensor cells arranged in a single-layer circular pattern proximal to the substrate. The plurality of wedge shaped sensor cells are arranged in a rotationally symmetric pattern about a center of the single-layer circular pattern. A sensor cell of the plurality of wedge shaped sensor cells comprises a first sensor electrode and a second sensor electrode separated by a border. The first and second sensor electrodes are configured for detecting changes in capacitance caused by one or more input objects. The first and second sensor electrodes become substantially thinner in width approaching the center of the single-layer circular pattern than at a distance further from the center. A sensor circuitry is communicatively coupled with the sensor electrodes of the sensor cell and the sensor circuitry is configured to interpret the changes in capacitance.

摘要： The embodiments described herein provide devices and methods that facilitate improved performance. Specifically, the devices and methods provide the ability to determine object information for objects causing deflection of a surface of a capacitive sensor device. The devices and methods are configured to determine an estimated deflection response associated with a deflection of the at least one sensing electrode using a set of sensor values, where the deflection was caused by one or more objects in contact with the input surface. The estimated deflection response at least partially accounts for effects of capacitive coupling with the object(s) in contact with the input surface, Object information may then be generated using the estimated deflection response. Where the input device is used to direct an electronic system the object information may be used to facilitate a variety of interface actions on a variety of different electronic systems.
