A human-centric and cooperative architecture for multiple target tracking in a smart home

Every home has its own unique considerations for location-aware applications. This makes a flexible architecture very crucial for efficiently integrating various tracking devices for adapting to real human needs. We employ tracking sensors from two different categories, those with seamless sensors and those with seamful ones. This allows us to take human-centric needs into consideration and to facilitate cooperative interaction among sensors from the two categories. Such cooperative interaction aims to increase the accuracy of location estimates and to compensate for the limitations of each sensor via cooperative interactions, which allows us to track multiple targets simultaneously in a more reliable way. Moreover, the approach demonstrated in this paper can serve as a guideline to help users customize sensor arrangements to fulfill their requirements. Our experimental results, which comprise three tracking scenarios using a load sensory floor as the seamless sensor and RFIDs as seamful sensors, demonstrate the effectiveness of the architecture.
