Abstract

This paper describes the case study of applying projection-based augmented reality, especially for dynamic objects in live performing shows, such as plays, dancing, or musicals. Our study aims to project imagery correctly inside the silhouettes of flexible objects, in other words, live actors or the surface of actor’s costumes; the silhouette transforms its own shape frequently. To realize this work, we implemented a special projection system based on the real-time masking technique, that is to say real-time projection-based augmented reality system for dynamic objects in performing arts. We installed the sets on a stage for live performance, and rehearsed particular scenes of a musical. In live performance, using projection-based augmented reality technology enhances technical and theatrical aspects which were not possible with existing video projection techniques. The projected images on the surfaces of actor’s costume could not only express the particular scene of a performance more effectively, but also lead the audience to an extraordinary visual experience.

Highlights

  • In contemporary performing arts, we can find various attempts at furnishing the audience with different visual experience by video projection

  • We presented a projection-based augmented reality technique for a dynamic object for performing arts, which can be used effectively by merging performance costume and digital technology

  • Our research started in order to provide interesting visual experience to the audience

Summary

Introduction

We can find various attempts at furnishing the audience with different visual experience by video projection. AR can project contents such as images or videos onto the unconstrained nonplanar forms This technique offers the experience of visual immersion to the audience by representing the sets of stage as a virtual environment or virtual world rather than showing the background of a stage on rectangular planes [2,3,4]. The dynamic objects we consider in this paper are continuously moving actors and actors’ costumes; the costume in the genre of performing arts is one of the important elements of performance, describing the actor’s character. This paper proposes an advanced performing technique, which we call a real-time projection-based augmented reality system for dynamic objects in the performing arts, to provide the audience with distinctive visual experience through our research. We discuss the lessons learned from this research and the direction of future work
