In this Demo, we present the design and implementation of a novel human localization and tracking system based on pyroelectric infrared(PIR) sensors. It is a new approach to setup several low-cost sensors to improve the simplicity of deployment. We first present a novel design in mechanical architecture, circuit board and sensors which enables our PIR sensor based system to detect the moving objects...
With the proliferation of context-aware services and human-computer interaction scenarios, the novel techniques of motion detection have attracted growing interests. There are many products which use camera, infrared sensors, RF, etc. With more Wi-Fi devices in homes and the ability to measure the PHY layer infomation, Wi-Fi based motion detection has attracted more attention than before. In this...
This paper presents the design and implementation of a novel user-initiated indoor localization system called QiLoc. QiLoc is a simple yet effective way to accurately locate and identify occupants of Qi-compatible devices inside buildings. The system is composed of QiLoc Stations and a QiLoc Server. A QiLoc Station is usually embedded inside or under a desk/table. By using the Qi wireless charging...
