In this work, we show the existence of human radio biometrics and present a human identification system that can discriminate individuals even through the walls in a non-line-of-sight condition. Using commodity WiFi devices, the proposed system captures the channel state information (CSI) and extracts human radio biometric information from WiFi signals using time-reversal (TR) technique. By leveraging the fact that broadband wireless CSI has significant number of multipaths, which can be…

Respiration Tracking for People Counting and Recognition

Using the channel state information (CSI) of a single pair of commercial WiFi devices, a novel system is proposed to continuously track the breathing rates of multiple persons without such impractical assumptions and can do people counting and recognition simultaneously.



Capturing the human figure through a wall

RF-Capture tracks the 3D positions of a person's limbs and body parts even when the person is fully occluded from its sensor, and does so without placing any markers on the subject's body.

Multi-Person Localization via RF Body Reflections

WiTrack2.0 is presented, a multi-person localization system that operates in multipath-rich indoor environments and pinpoints users' locations based purely on the reflections of wireless signals off their bodies.

Understanding and Modeling of WiFi Signal Based Human Activity Recognition

CARM is a CSI based human Activity Recognition and Monitoring system that quantitatively builds the correlation between CSI value dynamics and a specific human activity and recognizes a given activity by matching it to the best-fit profile.

Whole-home gesture recognition using wireless signals

WiSee is presented, a novel gesture recognition system that leverages wireless signals (e.g., Wi-Fi) to enable whole-home sensing and recognition of human gestures and achieves this goal without requiring instrumentation of the human body with sensing devices.

FIMD: Fine-grained Device-free Motion Detection

This paper presents an Indoor device-free Motion Detection system (FIMD), designed based on the insight that CSI maintains temporal stability in static environment, while exhibits burst patterns when motion takes place and uses a novel feature extracted from CSI to leverage its temporal stability and frequency diversity.
