Action recognition for human-marionette interaction.

ABSTRACTIn this paper, we propose a human-marionette interaction system based on a human action recognition approach for applications to interactive artistic puppetry and a mimicking-marionette game. We developed an intelligent marionette called "i-marionette" that is controlled by a sophisticated control device to achieve various human actions. Moreover, we utilized an action recognition approach to enable the i-marionette to learn and recognize complex dance movements. The idea of artistic puppetry is to present a conflict scenario between two different cultural worlds: the performer is active and represents the culture of modern technology based in the real world. In contrast, the i-marionette represents traditional culture and is passive and based in a virtual world. The active performer guides the passive i-marionette to form a space-time connection between the real world and the virtual world. The i-marionette mimics the performer's action, while the performer also mimics the i-marionette's action. The performance represents an artistic conception in which humans invent technology and the i-marionette is manipulated by human control. However, in this interactive circle, the human is implicitly affected by the i-marionette. In our mimicking-marionette game, a player mimics the i-marionette's action. Subsequently, our human action recognition system measures the action similarity between the player and the i-marionette, and our system provides a similarity score.
