PDF: Evaluation of factors affecting distance perception in immersive virtual environments during virtual visits of houses

Abstract

Virtual reality (VR) is increasingly used as a validation tool of architectural projects. One of the major problems of immersive virtual visits, in this context, is the phenomenon well known of distance compression. Most studies that have investigated this problem of perception have focused on factors related to display devices such as field of view, motion parallax, etc. We propose a study of several factors that may affect distance perception in VR which have not yet been the subject of thorough research.

We present the results of an experiment aimed to study the impact of three factors on the perception of distances and volumes: 1) the cognitive profile 2) the furnishing of houses and 3) the speed of navigation. The results of the experiment shown that these three factors influence the perception of distances and volumes as well as the immersion. The following recommendations can be highlighted. First, a slow navigation speed promotes the immersion. Further, it facilitates the task of distance estimation and leads to good estimations. Second, virtual visits are better in furnished houses. They offer a perception of distances similar to the case of unfurnished houses while providing a better understanding of the space.
