Indoor context information such as user positions and activities is essential to implement a variety of context-aware applications such as a home automation system and a surveillance system for an independently living elderly person. Due to the recent development of wireless communication technologies, indoor context recognition using Wi-Fi signals has been attracting attention. This paper introduces our studies on recognition of indoor context information based on Wi-Fi signals: (1) easy-to-install indoor positioning, (2) accurate state estimation of indoor objects, and (3) position-independent gesture recognition.
