Holography: Virtual Space and Real Time

We already know that the holographic image, because of its ephemeral nature, appeals to the concept of virtual space and to a certain idea of the unreal. This distinctiveness, associated with the alternating appearance and disappearance of the image, leads the viewer to develop new perceptual behaviors, both mental and physical. This automatically implies a kind of interactivity between the hologram and the viewer. It is important to notice that, because holograms present more than can be seen from a single point of view, any modification of the image's appearance involves movement of the viewer's body. This active mode of perception also allows the viewer choices of viewing positions offering the possibility of looking beyond or into the field of view or, in the case of rainbow holograms, of varying the colours.
