3D Tracking via Body Radio Reflections. Adib, F., Kabelac, Z., Katabi, D., & Miller, R., C. In Proceedings of the USENIX Conference on Networked Systems Design and Implementation (NDSI), pages 317-329, 2014. USENIX Association. ![3D Tracking via Body Radio Reflections [link]](https://bibbase.org/img/filetypes/link.svg "link")
Website abstract bibtex This paper introduces WiTrack, a system that tracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds current RF localization systems, which require the user to hold a transceiver. Empirical measurements with a WiTrack prototype show that, on average, it localizes the center of a human body to within a median of 10 to 13 cm in the x and y dimensions, and 21 cm in the z dimension. It also provides coarse tracking of body parts, identifying the direction of a pointing hand with a median of 11.2°. WiTrack bridges a gap between RF-based localization systems which locate a user through walls and occlusions, and human-computer interaction systems like Kinect, which can track a user without instrumenting her body, but require the user to stay within the direct line of sight of the device.
