Abstract
A processing system for an input device, including: sensor circuitry configured to receive resulting signals from a plurality of force sensors of the input device; and processing circuitry configured to: determine a first position of a first input object and a second position of a second input object on a surface of the input device; determine a plurality of force values based on the resulting signals; calculate a first aggregate force metric for a first region of the input region based on a first subset of the plurality of force values; determine that the first region has an input force based on a first comparison involving the first aggregate force metric; calculate a first distance between the first position and a first region and a second distance between the second position and the first region; and determine that the first input object is applying the input force in response to the first distance being smaller than the second distance.
