The stage machinery enabling the audience members to watch different contents depending on their position by vision control film and pepper’s ghost

In this research, we aim to create a stage machinery enabling audience members of a stage performance to watch different contents dependent to their position. To achieve this goal, we combined a vision control film whose transparency changes depending on the viewing angle with the classic Pepper’s ghost effect. Therefore, the system enables the audience members in the same theater to watch different scenes (live actors only, ghosts only, or both) depending on their position. This paper will describe our research motivation, design and implementation of the proposed system, and the operation results.
