Sound Feedback for Powerful Karate Training

We have developed new sound feedback for powerful karate training with pleasure, which enables to extract player’s movement, understand player’s activities, and generate them to sounds. We have designed a karate training environment which consists of a multimodal room with cameras, microphones, video displays and loud speakers, and wearable devices with a sensor and a sound generator. Experiments have been conducted on ten Karate beginnners for ten months to examine the effectiveness to learn appropriate body action and sharpness in basic punch called TSUKI. The experimental results suggest the proposed sound feedback and the training environments enable beginners to achieve enjoyable Karate.
