The last two decades has seen an exponential proliferation of Wi-Fi devices. Wi-Fi capability today is incorporated in a diverse set of devices such as smart phones, gaming consoles, and video players. In this talk, I will show how to leverage the ubiquity of Wi-Fi to enable rich sensing capabilities such as gesture recognition. Specifically, I will present WiSee, a novel gesture recognition system that leverages wireless signals to enable whole-home sensing and recognition of human gestures. Since wireless signals do not require line-of-sight and can traverse through walls, WiSee can enable whole-home gesture recognition using few wireless sources. Further, it achieves this goal without requiring instrumentation of the human body with sensing devices. Our proof-of-concept implementation shows that WiSee can identify and classify a set of nine gestures with an average accuracy of 94%.
