Creating smart indoor environments that detect and understand human daily life activities is attracting significant amount of attention, due to their huge potential impact on context-aware technologies. Aerial Technologies, our partner organization, is developing products that provide device-free indoor localization and activity recognition Wi-Fi signals generated by off-the-shelf Wi-Fi enabled devices. This project will use […]

In this project, we are interested in device-free methods that passively sense, monitor, and track people’s indoor presence, location, and movement using off-the-shelf Wi-Fi-enabled devices. We use information extracted from the physical layer of wireless links to detect and interpret human presence, location, and physical activities. The current design and implementation of Wi-Fi-based systems exhibit […]

As the world aging process quickened, the need for healthcare solutions to support seniors living on their own is recognized as a serious medical and social problem. Though an extensive amount of research has been carried out to investigate human activity based on a range of device-oriented (e.g., wearable) and device-free (e.g., vision based) sensing […]
