Authoring System for Choreography Using Dance Motion Retrieval and Synthesis

Dance animations of a three-dimensional (3D) character rendered with computer graphics (CG) have been created by using motion capture systems or 3DCG animation editing tools. Since these methods require skills and a large amount of work from the creator, automated choreography synthesis system has been developed to make dance motions much easier. However, those systems are not designed to reflect artists’ preferred context of choreography into the synthesized result. Therefore, supporting the user’s preference is still important. In this paper, we propose a novel dance creation system that supports the user to create choreography with their preferences. A user firstly selects a preferred motion from the database, and then assigns it to an arbitrary section of the music. With a few mouse clicks, our system helps a user to search for alternative dance motion that reflects his or her preference by using relevance feedback. The system automatically synthesizes a continuous choreography with the constraint condition that the motions specified by the user are fixed. We conduct user studies and show that users can create new dance motions easily with their preferences by using the system.
