This study proposed a dance training game applied using game theory by using wearable devices. The system extracts the teacher’s motions by using motion capture sensor technology. The pressure on the foot was sensed while dancing, and the motions of the ankle were extracted. The exergame enables students to watch the teacher’s dance in all directions by using an avatar and gaining the effects of both exercise and education by repeatedly practicing avatar’s dancing. To overcome the space constraints of the special equipment in the course of acquiring and measuring the students’ movements and to allow students to practice at any place, the movements of the user’s foot were measured by using a sock type wearable device that the user wears in their lives normally.
