Observation of Human-Object Interaction Using Distributed Sensors

This paper presents an observation system of human-object interaction. In intelligent environments, describing and recognizing human activity are one of the important issues in order for the environment to provide suitable services for users. To describe user activity in more details, we have focused on objects’ information. We can consider that objects’ information consists of both static information such as names, size, colors, and shapes of objects and non-static information such as use of frequency, users, locations, and ways to use them. Static information of objects can be given because we can consider that it will not change. Non-static information, however, depends on actual situation in which objects are utilized by people. We therefore focus on obtaining such non-static information via human-object interaction. This paper addresses an improvement of an observation system of human-object interaction.
