«A video camera is mounted on the wall of a completely darkened room at a height of about two metres. It points along a path almost parallel to the wall. The live video image is projected onto the adjacent wall, which is c. 150 cm away from the camera.
Approximately 50 cm above the camera there is an infra-red light-bulb which ensures that the light is adequate for the camera's photosensitivity. The video projector is also placed close (c. one metre in front) to the projection surface, so that the video image is projected onto the wall at an angle of 30°. As a result, the projection field and the video image converge slightly towards the direction of the camera.
When the viewer enters the narrow, corridor-like recording area, his/her head and upper body are recorded and projected onto the wall. As the person moves along the invisible 'corridor' of the camera field, the live image becomes either bigger or smaller. The image is distorted due to the camera and projector positions. By using a 'glowing' light source with a low wattage, Campus achieves the optimal light situation with which to focus on the camera field.»
