Abstract: An electronic device can include gain-based error tracking for improved force sensing performance. The electronic device can comprise a plurality of force sensors (e.g., coupled to a touch sensor panel configured to detect an object touching the touch sensor panel). The plurality of force sensors can be configured to detect an amount of force with which the object touches the touch sensor panel. A processor can be coupled to the plurality of force sensors, and the processor can be configured to: in accordance with a determination that an acceleration characteristic of the electronic device is less than a threshold, determine an error metric for one or more of the plurality of force sensors, and in accordance with a determination that the acceleration characteristic of the electronic device is not less than the threshold, forgo determining the error metric for one or more of the plurality of force sensors.

Abstract: An electronic device is disclosed. The electronic device comprises a touch sensor panel configured to detect an object touching the touch sensor panel and a plurality of force sensors coupled to the touch sensor panel and configured to detect an amount of force with which the object touches the touch sensor panel. A processor is coupled to the plurality of force sensors, the processor configured to: measure a first value from a first force sensor of the plurality of force sensors; measure a second value from a second force sensor of the plurality of force sensors, different from the first force sensor; and determine a motion characteristic of the electronic device based on the first value and the second value.
