This paper describes our design and implementation of a new augmented live stage system called Motion Groove. Our system is a new application of a Mixed Reality system. On a live stage, because of lighting production, the optical environment changes violently. Conventional positioning systems used for motion capture cannot be used in this environment. We have developed a positioning system that can be used during live performances on stage. The positioning system has three features. The system can recognize multiple optical beacons simultaneously up to 255. It can track optical beacons that move quickly such as when attached to the limbs of dancers. It is robust to changes in the optical environment e.g. complete darkness, spotlights, sunlight. We implemented the live stage augmentation system called Motion Groove using a positioning system, and confirmed its practicality.
