Spatialized audio for mixed reality theater: the Egyptian oracle
MetadataShow full item record
In the Egyptian Oracle, we project a simulation of an ancient temple onto a large projection screen. (See http://publicvr.org/egypt/oracle/shortvid.html). We create the illusion of a contiguous space by matching the scale of virtual and physical objects. In the live performance, actors in front of the screen interact with human-operated avatar actors in the virtual space. As with any dramatic production, music, sound, and dialogue are a large part of the experience. Our goal is to create a unified aural space that extends from the physical through the virtual to encompass the entire performance. We use commodity electronics to produce an elegant affordable solution, which produces an impressive dramatic effect. We also confront fundamental issues in performances of this type, pointing the way to more advanced auditory solutions for interactive mixed reality spaces. This project was funded by the National Endowment for the Humanities, and everything is free to the public as open source.
