Motion synthesis with extended posture transition graph and dynamic motion balancing

Abstract

This paper presents a technique for generating DDR dance motion interactively according to the specified user input. In generating a dance motion, we have to consider that the same sequence of steps does not necessarily mean the same movement. In order to generate a variety of dance motion, we have introduced an Ex-tended Posture Transition Graph for storing example motion clips and searching them efficiently. The EPTG allows multiple motion clips for a given input so that the resulting motions can have diversity in their traits even with the same user inputs. In the run-time, when a user specifies an input sequence, the EPTG will be traversed according to the input to retrieved a desired motion clip. Each retrieved motion clip is concatenated with motion transition technique to remove jerkiness. The resulting motion is further enhanced with the dynamic motion balancing technique to meet physical property of the motion.
