Memory Theater VR is an example of a virtual museum that embodies original architectural, interface and visualization strategies that converge the experience of real and virtual formations. The installation itself is set inside a cylindrical space, which is constructed out of wood panels that resemble a theater set. The user interface, a three dimensional spatial tracking device, can be moved around inside a clear plexi-glass replica of this cylindrical enclosure, and images are projected onto a large curved screen that is set into the circular wall opposite the interface. Moving the interface device allows the viewer to choose and enter four distinct virtual spaces through a clock-like compass, North, East, South, West indicating the four different virtual spaces, each of which is also a virtual replica of the overall cylindrical architecture of the installation. In each of these represented spaces there is a specific scenography of images and objects that are arranged inside this shared architectural environment, and the projection screen in the virtual space becomes a surface for showing film clips. The content of this installation is a personally contrived cultural and technological history of virtual reality. The four thematic worlds constitute a virtual memory theater of diverse quotations and references from the history of art, science, theater, literature, cinema and architecture. Specific precursors of modern virtual reality techniques are re-embodied such as tromp l'oeil, anamorphoses. The concept of the memory theater is used as a frame to create a newly compound space that is both a virtual museum and curiosity cabinet of heterogeneous images and artifacts that encompasses a profuse collection of works arranged in the following groupings: South (pioneers of modern virtual reality research ) SCOTT FISHER IVAN SUTHERLAND JIM CLARK HUGHES (UK) LTD.
