Functional magnetic resonance imaging (fMRI) provideshigh-resolution, voxel-wise measurements of brain activity, butacquiring large-scale fMRI datasets is expensive, immobile,and time-consuming. At the same time, commodity wirelessdevices continually capture channel state information (CSI)— a rich, multi-dimensional signal that reflects environmentalchanges and human motion. This paper investigates whethercarefully processed CSI can serve as a low-cost, portableproxy for coarse … Continue reading CSI→Voxel: Wi-Fi Sensing as a Low-Cost fMRI Proxy
