PSYCHIC SPACE was the next implementation where only one person interacted in the environment. The floor, walls, and ceiling were covered with black polyethylene with a rear-projected screen at one end and a phosphorescent pigment painted wall on the opposite side. The floor was divided into a sensing grid with pressure sensors which not just mapped the position of the participant but also produced sound.
MAZE, one of the interactions in this system, had a participant navigate a maze projected on the screen by moving around the room. A graphic represented the participant and responded to his movement. Participants would soon indulge in cheating to navigate the maze but such misdemeanors were built into the system and the first such transgression would lead to the elastic stretching of a line. Next the participants symbol would split into half with only one part following the movement. The other interactions were that the maze itself would shift or the maze would change, or new boundaries would appear, among others.
It was interesting to note that in all the experiments, Myron Krueger noticed that people feel a similar sense of self-consciousness with their images as they feel about their bodies. They had a proprietary feeling about their images as what happened to the image happened to them.
