Human movement constitutes a fundamental part of the archaeological process, and of any interpretation of a site's usage; yet there has to date been little or no consideration of how movement observed (in contemporary situations) and inferred (in archaeological reconstruction) can be documented. This paper reports on the Motion in Place Platform project, which seeks to use motion capture hardware and data to test human responses to Virtual Reality (VR) environments and their real-world equivalents using round houses of the Southern British Iron Age which have been both modelled in 3D and reconstructed in the present day as a case study. This allows us to frame questions about the assumptions which are implicitly hardwired into VR presentations of archaeology and cultural heritage in new ways. In the future, this will lead to new insights into how VR models can be constructed, used and transmitted.

Experimental archaeology is often cited as an important asset in the study of human interaction with material culture, especially in remote periods of history where there are few other sources of data on the human interventions which constitute the archaeological record. This has found many expressions in the discourse of archaeological theory, including the so-called chaîne opératoire, or ‘operational sequence’ theory (see e.g. Bar-Yosef and Van Peer 2009). However, due to an understandable desire to adhere to empirical evidence, means of inferring the human movement behind those interventions are rarely considered in the computational reconstruction of archaeological environments. The most obvious reason for this is that buildings, features and artefacts can be understood and reconstructed (whether digitally or not) from empirical archaeological remains, whereas there is little or no direct evidence for how people might have looked and moved through the spaces they created. Approaches which seek to go beyond this are methodologically fraught, resulting in a limitation of the scope of 3D reconstruction, both as a tool for archaeological research and as means of presenting cultural heritage to the public. The impact on the user's experience of those reconstructions is also limited. In a review of 3D visualization in archaeology, Gillings states: ‘[I]t is worth noting that one of the most striking things about archaeological Virtualmodels is the lack of people in them.
