The original idea of the 5-sided projection installation is based on the concept of the CAVE (CAVE Audio Visual Environment) by Carolina Cruz-Neira. Here, the user is located in a cube with projected side surfaces, floor and ceiling, which completely cover their field of vision. In contrast to the Powerwall, the user not only has the impression of interacting with a virtual world, they actually feel like they are inside it. In 2023, the original CAVE, consisting of 5 projection surfaces, each with 2 projectors, was replaced by a 5-sided CAVE consisting of LED walls. The projection takes place with the aid of active stereo display. The projection installation is controlled by a computer network of 7 synchronized nodes, whereby 5 nodes of the system are used for image generation (one for each projector) and 1 node for controlling the display nodes and updating the scene. The 7th node serves as a backup for the control node. It has a permanently installed position detection system with 4 cameras on the ceiling.
