Research on “Kire” of Karate movement using wearable devices

-2nd report Proposal of measurement method of karate movement using microcomputer devices -

Abstract

In this research, we aim to elucidate “Kire (Sharrpness)” in Karate movements using wearable devices. If we could understand important points in karate movement, it is considered for us useful for guidance and evaluation about Karare practice and competition. Previous report, we verified the “Seiken-duki” (Fore fist punch), which is the basic movement of Karatedo. We uses three devices which can measure acceleration and angular velocity[1]. However, the large measuring devices put a burden on performing the Karate operation.

In this paper, the aim is to make the devices smaller. We verify whether the same result as the first report can be obtained by using the create small devices. In the experiment of this paper, we also verified the motion of hand’s wrists and waist movement for an experienced player and a first time player.
