Detect and monitor human's information using wireless technologies in a non-intrusive manner.
This project aims to sense human activities with wireless signals in a non-intrusive way. We now focus on solving problems on multi-person wireless sensing, including multi-person respiration monitoring and people counting using WiFi devices.
In this project, we build a physical model for counting people passing by the gateway based on the phase difference information of wireless signals. We propose to realize people counting in a low-cost (using WiFi-existing infrastructure), accurate (can count multiple people passing by at the same time) and non-intrusive (no need for carring devices and active participation, privacy-protected).
