Online generation of tango choreography using tempo estimation

Abstract

In this paper, synthesising tango choreographies from tango dances is aimed. This system takes tango dance patterns performed by human dancers as input and produces choreographies that are represented in 3 dimensional virtual environment. Dance figures obtained by motion capture system are segmented automatically and analyzed with regard to weight center to form the dance database. Choreographies are then created by combining compatible primitives and adapting them to each other while transforming them to match the song tempo. The system's efficiency is verified with tests using an array of songs having varying tempos as well as synthetic songs having constant tempo.
