Systems and methods are disclosed herein for determining the amounts of force applied by at least two fingers of a user to a touch input device having a touch input surface. In one example, a system may include a plurality of force sensors distributed about the touch input surface; a plurality of touch sensors distributed about the touch input surface; and a module for apportioning a first amount of force as measured by the plurality of force sensors to one of the at least two fingers, and for apportioning a second amount of force as measured by the plurality of force sensors to another of the at least two fingers. The system may also include a persistent data structure including force calibration data with force deflection measurement values as measured by each of the plurality of force sensors in response to a standardized force applied to various known locations on the touch input surface. The system may also include one or more matched filter modules.

Apportionment of forces for multi-touch input devices of electronic devices

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.

Force sensor-based motion or orientation determination in a device

An electronic device displays, on a display, a user interface. While displaying the user interface, the device detects an input on the touch-sensitive surface; and, in response to detecting the input while displaying the first user interface, and while detecting the input, in accordance with a determination that the input satisfies an activation intensity threshold, performs a first operation. The activation intensity threshold includes a first intensity threshold component that decreases from a first intensity value over time.
