by Shyamnath Gollakota

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