"Virtual Taekwondo Exhibition" is an AR content that allows you to train Taekwondo movements with virtual masters. "The King of Taekwondo" is a virtual competition content. "This VR and AR content stimulates vision, hearing, and touch, such as using equipment and sensors and recognizing the movements of experienced people, so you can experience realistic Taekwondo." In particular, we have developed it so that we can feel the touch of hitting and defending by wearing vibration sensors on our hands, feet, and upper body."
