Wi-Fi signals enable gesture recognition throughout entire home
<i>>A standard Wi-Fi router could be adapted to function as a receiver.</i><p>The article and the embedded video do not make it entirely clear but if this technology could be deployed in existing Wi-Fi routers with relative ease [1] then it could have far-going implications for both privacy and the physical security of anywhere where there's Wi-Fi. Once it's easy enough to deploy on a hacked device that a hired script kiddie can do it even simple burglars could take an interest in residential  routers to know when nobody's home.<p>I wonder if this will affect the market for embedded Linux security consulting in a major way.<p>[1] I.e., without modifying the hardware and with no need for manual calibration.
