SYSTEM AND METHOD FOR DETERMINING INPUT OBJECT INFORMATION FROM PROXIMITY AND FORCE MEASUREMENTS |
摘要 |
A processing system for an input device having a sensing region overlapping an input surface and an array of sensor electrodes configured to form a plurality of proximity pixels and a plurality of force pixels. The processing system is configured to: determine a proximity image indicative of positional information for input objects; determine a force image indicative of local deflection of the input surface in response to force applied by the input objects; determine a respective group of proximity pixels from the proximity image corresponding to each input object; determine a respective group of force pixels from the force image corresponding to each determined group of proximity pixels; determine the position of each input object based on the determined groups of proximity pixels; and determine the force associated with each input object based on the determined groups of force pixels. |

1. A processing system for use with an input device of the type including a sensing region overlapping an input surface, and an array of sensor electrodes configured to form a plurality of proximity pixels and a plurality of force pixels, the processing system communicatively coupled to the array of sensor electrodes and configured to:
determine a proximity image indicative of positional information for input objects in the sensing region, based on a variable capacitance associated with each of the plurality of proximity pixels; determine a force image indicative of local deflection of the input surface in response to force applied by the input objects, based on a variable capacitance associated with each of the plurality of force pixels; determine a group of proximity pixels from the proximity image corresponding to each input object in the sensing region; determine a group of force pixels from the force image corresponding to each determined group of proximity pixels; and determine the force for at least one input object based on the determined groups of force pixels. |
