Course Description

Overview

Explore a groundbreaking conference talk from NSDI '14 that introduces WiTrack, an innovative system for 3D motion tracking using radio signals reflected off the human body. Delve into the technology that enables tracking through walls and occlusions without requiring users to carry any wireless devices. Learn about WiTrack's impressive accuracy in localizing the center of a human body and its ability to provide coarse tracking of body parts. Discover how this system bridges the gap between RF-based localization systems and human-computer interaction systems like Kinect. Gain insights into the technical aspects of WiTrack, including reflection time, FMCW, multipath reflection, and dynamic multipath. Examine the system's performance, accuracy measurements, limitations, and potential future developments in this 26-minute presentation by researchers from the Massachusetts Institute of Technology.
