# Virtual replicas of real places: Experimental investigations

## TL;DR

This paper investigates how users perceive virtual replicas of real places in VR, emphasizing the importance of accurate scale, coherence, and lighting in creating a realistic experience through three user studies.

## Contribution

It provides empirical insights into user perception of real-place replicas in VR, highlighting key factors influencing perceived realism.

## Key findings

- Correct scale is crucial for realism.
- Incoherent behaviors reduce perceived authenticity.
- Lighting has minimal impact on perceptual similarity.

## Abstract

The emergence of social virtual reality (VR) experiences, such as Facebook Spaces, Oculus Rooms, and Oculus Venues, will generate increased interest from users who want to share real places (both personal and public) with their fellow users in VR. At the same time, advances in scanning and reconstruction technology are making the realistic capture of real places more and more feasible. These complementary pressures mean that the representation of real places in virtual reality will be an increasingly common use case for VR. Despite this, there has been very little research into how users perceive such replicated spaces. This paper reports the results from a series of three user studies investigating this topic. Taken together, these results show that getting the scale of the space correct is the most important factor for generating a "feeling of reality", that it is important to avoid incoherent behaviors (such as floating objects), and that lighting makes little difference to perceptual similarity.
