Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not
only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times.
In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of
Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.
