| Research Abstract |
We conducted this research project aiming to establish methodologies of verbalizing physical skills by means of knowledge discovery technologies. We selected cello bowing and batting as our research targets. More concretely, we conducted researches on (1) developing physical models of body skills and discovering key points, (2) extracting skill rules by means of time series data mining, (3) extracting key points by means of meta cognition and (4) building a skill discovery and diagnosis support system based on abduction.
In (1), we developed a pendulum model, a rotation model and a whip model to describe human skill motion and extracted key points from the developed models. In (2), we succeeded in extracting positive skill rules such as propagating motions from the body trunk to extremities. We also extracted motion integrity constraints as negative skill rules. In (3), we continuously collected self analysis in performing batting and observed the change of focus in consciousness and relation between the change of focus and rapid skill improvement. In (4), we designed a skill discovery and diagnosis support system based on abductive inference system PrologClA in the case of cello playing and we succeeded in showing the feasibility of the approach.
Furthermore, we held an International Symposium on Skill Science 2007 partly to publicize our research results of this project and we provided an opportunity for presenting research results as well as to discuss future direction of the skill science through the panel discussion.
