Touch-sensitive button with two levels

摘要

A touch-sensitive depressible button with multiple depression thresholds is provided. When the button is depressed to a first depression threshold, the touch sensor can be switched from a low-power, non-sensing state to a sensing state. When the button is depressed to a second depression threshold, the touch sensor can sense the touch context and input can be generated based on the depression and the touch context. In this way, the touch-sensitive depressible button with multiple depression thresholds can facilitate timely switching of the touch sensor to a sensing state.

主权项

1. A touch-sensitive depressible button comprising:
a touch sensor for detecting touch events on a surface of the touch sensor; and an actuator coupled with the touch sensor and depressible from an initial position to both a first and a second depression threshold; wherein the touch sensor is configured to switch from a non-sensing state to a sensing state when the actuator is depressed to the first depression threshold; and wherein the touch sensor is configured to detect touch events when the actuator is depressed to the second depression threshold.
