Motion Analysis of the Tea Whisk Concerning the Way of Tea

摘要

The way of tea is the Japanese tea ceremony. In this research, one super expert and an expert and beginner were employed as the behavior subject. During the tea-mixing process, the subject's motion and trace were captured by the high-speed camera system from top side of the participants. The coordinates of the right index finger in the x and y direction was captures and analyzed. Base on the data from the high-speed camera system, each key gesture of the subjects were focused, motion feature affected the final teas were extracted and analyzed. The tea-mixing process was divided into three kinds of processes according to the velocity of the tea whisk. In the case of the super expert, the action of the tea whisk was high speed at short time of the first period. And changed gesture and stirred around with uniform speed at second period. At third period, the action was decreased gradually.
