1. A device comprising;
- a receiver configured to receive wireless communication signals;
at least one processing unit configured to identify features in the wireless communication signals;
a memory accessible to the at least one processing unit and storing information regarding features in wireless communication signals caused by gestures; and
wherein the at least one processing unit is further configured to identify a gesture based on the identified features in the wireless communication signals.

Abstract
Examples of systems, devices, and methods are described herein that may provide for gesture recognition. Wireless communication signals may be received from sources in an environment (e.g. cellular telephones, computers, etc.). Features of the wireless communication signals (e.g. Doppler shifts) may be extracted and utilized to identify gestures. The use of wireless communication signals may accordingly make possible gesture recognition in a whole-home environment that may identify gestures performed through walls or other obstacles.

21. A system comprising:
-
a wireless communications device configured to provide periodic beacon signals using an OFDM protocol; a router configured to receive the periodic beacon signals from the wireless communications device, wherein the router is in communication with a memory storing a plurality of gesture signatures, and wherein the router is configured to detect a gesture based on a comparison of features in the periodic beacon signals from the wireless communications device and the gesture signatures, and wherein the router further includes a transmitter configured to transmit a control signal responsive to the gesture; and a controller coupled to a power outlet and including a receiver configured to receive the control signal, wherein the controller is configured to turn power on, off, or combinations thereof, responsive to the control signal. - View Dependent Claims (22, 23, 24)
