The use of virtual conversational agents is awaited in the tutoring of physical skills such as sports or dances. This paper describes an ongoing project aiming to realize a virtual instructor for ballroom dance. First, a human-human experiment is conducted to collect the interaction corpus between a professional instructor and six learners. The verbal and non-verbal behaviors of the instructor is analyzed and served as the base of a state transition model for ballroom dance tutoring. In order to achieve natural and highly interactive instruction during the multi-modal interaction between the virtual instructor and the learner, it is necessary to divide the learner's motion into small but meaningful segments in real-time. In the case of ballroom dance, the smallest meaningful unit of dance steps is called count which should be synchronized with the beats of accompanied music. A method of automatic extraction from the learner's dance practice motion into count segments is proposed in this paper. This method is based on trajectory similarity comparison between the motion of the learner and the data collected from a professional dance instructor using Angular Matrix for Shape Similarity (AMSS). Another algorithm for identifying the worst performed portion and the corresponding improvement of the learner's motion is also proposed. Finally, a comparison experiment between the prototype system and a non-interactive self-training system was conducted and reported.

本稿ではBluetoothによる受信信号強度を用いたユーザの位置推定手法を提案する.本手法は医療事故の発生要因の分析などにおいて重要となる,看護師のインタラクション情報を得るためのものである.本手法ではユーザに装着した移動局が複数の固定局から一定時間で得られる受信信号強度の平均値,最大値,最小値,中央値を特徴量として用いて位置推定を行う.本手法の有効性を評価するために,2床のベッドを配置した模擬的な病室環境での実験を行い,ベッド際のどの位置にいるかおよびそれ以外にいるかという識別については80%以上,どちらのベッドの患者に対するインタラクションかの識別においては90%以上の識別率が得られることがわかった.

In the environment that human and robots coexist, mobile robots have to approach human as much as possible in order to provide human with physical services. For friendly interaction with human, the robots should be able to afford human-affinitive movement. In this paper, human following, as one of human-affinitive movements, of robot is achieved. The human following robot requires several techniques; the recognition of the target human, the recognition of the environment around the robot, and the control strategy for stable human following. In this research, Intelligent Space, where many sensors and intelligent devices are distributed, is used for the recognition of the target human and the environment around the robot. The control law based on the virtual spring model is proposed to mitigate the difference of movement between the human and the mobile robot. The proposed control law is applied to Intelligent Space and its performance is verified by computer simulation and experiment.
