We have been producing live stage performances using computer graphics (CG) and interactive techniques. We developed a system to support and enhance live performances. This system projects CG onstage alongside real actors and allows users to control the projected images in real time. Collaborative scenes between real actors and virtual actors created by CG are possible. The system has multi-functions and is flexible, hence, it can be used for purposes other than performances. The system helps directors and actors in the creation of performances, as well as during rehearsals. Moreover, the system is portable and easy to set up in various types of theaters. The system can use sensor devices to determine physical expressions of actors or spectators. These perceived states can be used to affect projected images, which can provide a richer presentation. This paper describes the structure of the system and its effects in live performances that we attempted.

    ABSTRACT: How do you effectively use interactive technologies to involve spectators in a live performance without distracting from the atmosphere or storyline? We have been producing theatrical performances using computer graphics (CG) and interactive techniques. Our goal has been to use information technologies such as CG, augmented reality (AR), and interactive techniques in live stage performances. We sought to use interactive technology to involve spectators in a production employing projected screen imagery of CG characters in adaptations of Akutagawa Ryunosuke A Spider's Thread. This paper introduces the technology employed and resulting performance, focusing on one climactic scene of spectator involvement in a "lottery," as well as review of spectators' post-performance questionnaires.
