We tackle the problem of developing a wearable device that operates indoors on harvested RF energy, but can support gesture tracking applications require relatively energy-intensive inertial sensors. propose an infrastructure-assisted energy harvesting paradigm, where ubiquitously-deployed WiFi infrastructure helps to significantly improve power, by employing state-of-the-art techniques for device-free user localization and beamformed, directional packet transmission. Preliminary experimental results suggest these might be able intelligent, triggered mode recognition. The also point several practical challenges such opportunistically beamformed WiFi-based must address.
