A World Camera for Recording the Game Tactics in Martial Arts using Bamboo Swords

Abstract

The proposed system was designed for tankendo, kendo, or Japanese fencing using bamboo swords that also use a mask. First, a lightweight, miniaturized world-camera that is 3mm square, or smaller than the width of the vertical bar in the mask, is attached to the center of the vertical bar. This keeps the world-camera out of the field of vision of the competitor and protects the camera from damage. Second, a lengthened signal cable is connected to the control computer and compact power supply attached to the competitor's waist. This minimizes any discomfort a competitor might feel when using the system.
