The next question was how to extract those states. Originally, we assumed that those states correspond to points of brief stops along dance performance. After extracting brief stops along dance motions, we realized that too many brief stops were extracted. Among those brief stops, some were important points that correspond to a new state, while others were accidental ones.

We introduce music beats for discriminating those important stops from the accidental ones. If a brief stop occurs at the beat point, we consider the stop as an important and intentional one. Otherwise, we consider the stop as an accidental non-intentional one. The result is shown in Fig. 6. Figures 5 and 6 corresponds to each other. This result supports our assumption that a brief stop on a music beat is an important intentional one. We name the posture corresponding to an important stop as a key pose. We can define upper body tasks as transition between two key poses. Again, one task is defined as the interval, which starts from one key pose and ends immediately before the next key pose.
