Quantification of the Datsuryoku skill in the impact for a Japanese drum

Abstract

In this study, we suggest Datsuryoku evaluation algorithm for the purpose of quantification of the Datsuryoku that is the important skill in the Japanese drum. By the suggestion technique, we measure angular velocity and the line electric potential of the Japanese drum player and evaluate the estimate of the element of the movement and the Datsuryoku. In the estimate of the element of the movement, we suggested algorithm using cross-correlation function and DTW(Dynamic Time Warping). In addition, in the evaluation of the Datsuryoku, we suggested technique with the maximum value of the line electric potential. As a result of experiment, we confirmed that an evaluation not to depend on the level of the player was possible using suggestion technique. In addition, we confirmed that we could quantify a part of the skill of the Datsuryoku using suggestion technique.
