Abstract: 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.

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.

Abstract: 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.

Abstract: An electronic device that includes a proximity sensor may be provided. The proximity sensor may be a time-of-flight-based proximity sensor that is capable of separately outputting near-field measurements and far-field measurements. The near-field and far-field measurements may be placed in separate bins according to their time-of-flight values. The discrimination between near-field and far-field results may allow the electronic device to filter out false positive events where the presence of smudge or other surface contaminants can otherwise produce skewed readings and also to filter out false negative events where the presence of a user with dark hair or skin can otherwise produce misleading sensor results.

Abstract: Systems and methods for detecting user input to an electronic device are disclosed. The electronic device can include an input sensor system that itself includes an input-sensitive structure that compresses or expands in response to user input. The input sensor system measures and electrical property of the input-sensitive structure for changes. The input sensor system is coupled to an accelerometer to receive acceleration data to modify the detected changes to the input-sensitive structure.
