装着型体験記録装置による対話インタラクションの判別機能実装と評価

The purpose of our wearable experience capturing system is to recognize the interaction among humans. Various interactions, such as conversations, are effective index of the captured experience. We assume that the non-verbal information, such as the relative position among humans, head direction, and talking behavior, can be used for recognition of conversational interaction. We developed a wearable device, the head worn type local positioning system, called "InfraRed ID Tracker", to sense the relative position and the head direction. In this paper, we evaluate and discuss about accuracy of the experience capture and interaction recognition functions by use of the non-verbal information.
