Presence and Navigation: a Comparison Between the Free Exploration of a Real and a Virtual Museum

Abstract

The validity of environmental simulations resides in their capacity to replicate responses produced in a physical environment. However, no studies validate the similarity of navigation in immersive virtual environments, even though this can radically condition space perception and therefore alter the various evoked responses. The objective of this present paper is to validate environmental simulations using 3D environments and head-mounted display devices, at perception level by means of presence and at behavioural level through navigation. A comparison was developed between the free exploration of an art exhibition in a physical museum and a simulation of the same experience. At perception level, the virtual museum shows a high degree of presence. At navigation level, movement patterns show high similarity, and they present significant differences only at the beginning of the exploration in the percentage of area explored and the time taken to undertake the visits. The results suggest that there is an environmental adaptation effect of about 2 minutes. Subsequently, navigation in physical and virtual museums does not show significant differences. These findings support the use of immersive virtual environments as empirical tools in human behavioural research.

Perception of Light in Museum Environments: Comparison between Real-Life and Virtual Visual Experiences

“…Perceptual quality of these environments could be enhanced by using advanced numerical data, such as chromaticity and spectral data [42]. Virtual reality was used to evaluate qualitative effect of complex sunlight patterns [43]. A study on lighting features in various virtual environments demonstrated that virtual reality is the closest to physical space, in comparison to video and photograph reproductions [44].…”
