Characterization of tea whisking by Japanese Tea Ceremony performers

抄録

We have been able to prove that subtle, small differences in the movements of practitioners of the Japanese Tea Ceremony are not trivial and thus are enough to characterize the whisking. This characterization showed that the practitioners follow a path that is where the motion converges to. In order to produce the movements over this track, the whole arm is needed. We have demonstrated that coordination is a key element of a good whisking action. By this effect, we have introduced the skills of the Japanese Tea Ceremony practitioners to the light of skill science.
