Detecting and Processing Unsuccessfully Recognized or Unsuccessfully Utilized Non-Contact Gestures for a Computing System

摘要

This document describes techniques and systems that enable detecting and processing unsuccessfully recognized or unsuccessfully utilized non-contact gestures for a computing system. A radar field enables an electronic device to determine that a part of a user is within a gesture zone around the device. The device can determine whether an application that can receive input through touch-independent radar-based gestures (radar gestures) is operating on the device. Using these techniques, the device can present a failed-gesture feedback element on a display when the user unsuccessfully performs a radar gesture. The failed-gesture feedback element alerts the user that the user's attempted gesture did not meet the criteria to be a radar gesture. This provides the user with feedback, which can educate the user about the device's capabilities and allow the user to take advantage of additional functionality and features provided by the availability of the radar gestures.
