Karada OK: Matching Body Gestures while Musics Play

Karada OK, a term coined to bear similarity to the popular Karaoke, is a body gesture matching game. In a time span of a song, video of body movement performed by an exemplary coach is recorded as template, later, players are to match the recorded body gestures along with the music, with score given at the end of the game. Due to the unavoidable camera view difference between the one at recording template and that at game playing, direct comparison for matching scoring can be difficult. This paper presents a Kinect-based solution which utilizes Skeleton-based Invariant Transformation (SVIT) to circumvent the view difference problem.
