Embodiment Construction

[0023] In some implementations, it is desirable to detect the user's proximity to the keyboard of the computing device before the user presses a key. The perceived responsiveness of the computing device to user actions can be improved if the user's desired action is predicted before the user actually performs the action. For example, determining a user's proximity to a keyboard of a computing device before the user actually presses a key may cause the computing device to perform one or more actions in preparation for the possibility of a key press. For example, if the computing device is in a reduced power state and / or sleep state, the computing device may "wake up" and be ready to respond to a first key press or other input to the computing device immediately after the computing device receives an input . In another example, detecting the user's approach to the keyboard may turn on the keyboard's backlight function. Implementing these and many other features can improve the...

Abstract

In one general aspect, a system can include a key set including a plurality of keys, a membrane keyboard including a plurality of key pads and a plurality of interconnected sensor electrodes, where at least one of the plurality of key pads corresponds to a one of the plurality of keys. The system further includes a feature plate that provides a rigid backing for the membrane keyboard.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Nonprovisional Patent Application No. 14 / 584,898, entitled "KEYBOARD PROXIMITY SENSING," filed December 29, 2014, which in turn claims Priority to US Provisional Patent Application No. 61 / 921,695 filed entitled "KEYBOARD PROXIMITY SENSING," both of which are incorporated herein by reference in their entirety. technical field [0003] This description relates generally to computing devices. This description specifically relates to the use of proximity sensing. Background technique [0004] Computing devices may provide a number of ways for a user to control the operation of, and enter data into, the computing device. For example, a computing device may include a touch screen display, keyboard, mouse, trackpad, trackpad, pointing stick, one or more mouse buttons, trackball, joystick, and other types of input devices. As a user of a computing device provides input to the computi...
