South Korean researchers have developed a virtual dance teacher that can make it easier to learn famous K-Pop dances at home by precisely tracking 3D body joints.
K-pop is a musical genre originating in South Korea that is characterised by a wide variety of audiovisual elements.
Daijin Kim and his team at Pohang University of Science and Technology (POSTECH), South Korea, created the virtual dance teacher after developing precise 3D tracking of 15 human body joints using big data of the human body.

In order to develop the virtual K-Pop dance teacher, the team selected a hundred K-POP dance routines that were performed by a professional dancer and collected the moves of 15 body joints of each dancing movement.
They then extracted the moves of 15 body joints from a dance learner using the developed precise 3D tracking of body joints and evaluated the average similarity between the body joint movements of the dance learner and those of the professional dancer.
They also developed a score monitoring method based on the similarity and represented how much each body part of a dance learner is deviated from the corresponding body part of a professional dancer.
