Input Sensor with Acceleration Correction

摘要

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.

1. An input sensor system comprising:
an input-sensitive structure comprising:
a first resilient element; anda second resilient element positioned below and separated from the first resilient element; an electrical circuit in communication with the input-sensitive structure and configured to measure a distance separating the first resilient element and the second resilient element; an accelerometer; and an input resolver coupled to the electrical circuit and to the accelerometer, the input resolver configured to:
receive the measured distance from the electrical circuit;receive acceleration data from the accelerometer; andmodify the measured distance based on the acceleration data.
