Spatial Knowledge Acquisition in Virtual and Physical Reality: A Comparative Evaluation
This addresses the problem of evaluating VR training effectiveness for spatial skills, relevant for applications like emergency response, but is incremental as it builds on prior mixed results.
The study compared spatial knowledge acquisition in virtual reality (VR) and physical reality, finding no significant differences in time performance but noting other behavioral differences.
Virtual Reality (VR) head-mounted displays (HMDs) have been studied widely as tools for the most diverse kinds of training activities. One special kind that is the basis for many real-world applications is spatial knowledge acquisition and navigation. For example, knowing well by heart escape routes can be an important factor for firefighters and soldiers. Prior research on how well knowledge acquired in virtual worlds translates to real, physical one has had mixed results, with some suggesting spatial learning in VR is akin to using a regular 2D display. However, VR HMDs have evolved drastically in the last decade, and little is known about how spatial training skills in a simulated environment using up-to-date VR HMDs compares to training in the real world. In this paper, we aim to investigate how people trained in a VR maze compare against those trained in a physical maze in terms of recall of the position of items inside the environment. While our results did not find significant differences in time performance for people who experienced the physical and those who trained in VR, other behavioural factors were different.
