One of the problems we encountered in discussing what we conveniently may call the VR with the producer of the Odyssee theatre performance was the high expectancy people have of VR, no doubt inspired by movies as the Matrix and the like. In mixed reality applications, manipulating persons, warps in space, and basically any intensive image analysis or image manipulation is simply not possible in real time. Moreover, there is a disturbing tendency with the layman to strive for semantic overload by overlaying the scene with multiple images and lines of text, thus obscuring the reality captured by the camera and literally blocking the participants view and awareness of the scene. Basically, as a guideline, we tend to strive for 70% visibility of the scene, 20% image or projection transformations and only 10% of information in the form of text and images.
