Research Interests

Sensor, Mobile and Ubiquitous Computing Systems.

Projects

Project-Photo-IWRS 

IWRS

The Indoor WiFi Radar Sense (IWRS) project is a system to detect, localize, and identify human motions and the environmental contexts using WiFi signals, such as human detection, line-of-sight condition identification, breath detection and lips reading.

Project-Photo-PosX 

PosX

The PosX project is a meter-level accuracy indoor localization system using WiFi and inertial sensors of smartphones. It aims to integrate wireless-based positioning and mobility information to enhance localization accuracy, decrease deployment cost and enrich location context.

Project-Photo-OpenSense 

OpenSense

The OpenSense project aims at investigating community-based sensing using wireless sensor network technology to monitor air pollution. Current research focuses on sensor arrays, personalized air pollution monitoring, and air quality maps.
