Sažetak
This paper presents a quiz game agent who behaves attentively to the dynamics of multiple concurrent participants. The attentiveness of this agent is meant to be achieved with an utterance policy that determines whether, when, whom, and what to utter. Two heuristics are introduced to drive it: the interaction atmosphere (AT) of the participants and the participant who tends to lead the conversation (CLP) at specific time point. They are estimated from the activeness of the participants’ face movements and acoustic information during their discussion of the answer. In order to complement the inherent drawback of a 2D agent that multiple concurrent users can not distinguish the destination of its attention, a physical pointer is introduced in addition. This system is then evaluated by questionnaire investigation and video data analysis. From the joint results of the experiments, the methods for estimating AT and CLP worked. The participants paid more attention to the agent, participated the game more actively if the indication of the pointer is more comprehensive.
