报告简介：

RF-based activity recognition (the utilization of perturbations in RF signal strength and Frequency due to movement of objects and subjects) has been an active research topic for about a decade now. The field has mostly matured and diverse approaches (e.g. utilizing time-domain, Frequency-domain, phase, or Fresnel effect) as well as useful tools (Frequency Modulated Continuous Wave (FMCW), synthetic aperture radar, Radio holography,... ) have been discussed. Still, the field holds numerous open challenges, such as accurate multi-subject activity and gesture recognition, privacy concerns, tailored data processing tool chains, or sensor mobility. The talk will summarize and bridge from the early results in RF-based activity recognition, over notable achievements and applications to ongoing research direction and open issues.
