DEVICES, SYSTEMS, AND METHODS FOR CONTROLLING DEVICES USING GESTURES
First Claim
Patent Images
1. A method comprising:
- receiving, using a device, wireless signals after a gesture selected to control the device is performed;
analyzing, using the device, magnitude changes in amplitude of the wireless signals indicative of the gesture;
identifying the gesture based, at least in part, on the magnitude changes in amplitude in the wireless signals; and
responding to the gesture, using the device.

Abstract
Example devices, systems, and methods described herein extract gesture information from wireless signals. Examples described herein may extract gesture information from changes in the magnitude of the amplitude of the received wireless signals, or portions of the received wireless signals (e.g., channel state information, RSSI information, RCPI information). Time-domain classification of gestures may proceed based on the amplitude changes. In this manner, sufficiently low power operation may be achieved to enable “through-the-pocket” gesture recognition on mobile devices in some examples.

12. A device comprising:
-
a receiver configured to receive wireless signals and provide an indication, of magnitude changes of amplitude of the wireless signals over time; a classifier configured to identify an associated gesture based on the indication of the magnitude changes of amplitude of the wireless signals over time the classifier further configured to provide an indication of the associated gesture; and at least one processing unit configured to provide a response to the indication of the associated gesture. - View Dependent Claims (13, 15, 16, 17, 18, 19, 20)
