Abstract

Spatially Immersive Displays ('virtual rooms') and other variations have become readily available in the past few years. However, building one on your own is also possible, and this is what was attempted in Helsinki University of Technology. Two immersive display systems were built, one with single wall with 7-channel audio, and the other a full four- wall system with 16-channel audio, when a new building was completed. The differences and similarities between these systems are discussed, as well as the requirements a virtual projection system places on the building infrastructure, such as power, cooling, and lighting. The local modifications to the buildings made to fulfill these goals are described. A generic, simple virtual room recipe is presented, with details concerning frames and screens, which are the most complex parts. Special attention is paid to corners and edges, where disturbing artifacts may easily become visible. A technique used in the HUT virtual room, in which the visible edges are removed via a particular frame construction, is presented.
