Analysis of Interpersonal Effects in Dance Performance

This research investigated the interaction between dancers when performing together, and the differences in dancers' emotions and movements in the presence and absence of an audience. Both qualitative and quantitative analyses were performed using psychological indices and motion capture techniques, respectively. First, we investigated the interaction between the dancers. A comparison of the results of movement and timing of face-to-face and face-to-back positioning showed that the face-to-face condition led to better synchronization of timing. In addition, the dancers actively moved their waist, knees, limbs, and trunk to create complicated dance movements rhythms. Next, we investigated dancers' emotional states and movements in the presence of an audience. The results showed that positive and negative emotions of dancers increased in the presence of an audience; and the speed and acceleration of body movements also increased. Moreover, the dancers tended to perform movements with more complicated rhythms. These results can contribute to the development of a learning and support system for dance education.
