Hello, Chinese Ethnic and Folk Dances

China has a wealth of ethnic and folk dances, which are our national precious intangible cultural heritage. It is our obligatory responsibility to protect and inherit these precious treasures. This work aims to apply computer graphics and augmented reality (AR) techniques to the dynamic display of folk dances. We use the real motion capture data of the dance artists to drive virtual characters' dance performances. Meanwhile costumes and stage scenes with ethnic characteristics help to foil the atmosphere of dance. Our work not only solves the problem of unable to transmit motion capture data due to copyright restrictions, but also has a good sense of immersion and interactivity, which plays an active role in promoting the protection and inheritance of action-type intangible cultural heritage.
