Simulator Sickness and Performance in AR vs VR: A Comparative Analysis Applied to Additive Manufacturing

Abstract

Augmented Reality (AR) and Virtual Reality (VR) technologies are increasingly becoming integral to educational and training contexts, yet comparative analyses of their effects on simulator sickness and user experience remain limited. Recent advancements in AR/VR headsets, such as the Meta Quest 3, now allow virtual and augmented reality experiences to be delivered through a single device. However, previous research comparing user experiences between virtual and augmented reality did not account for the use of a unified headset in their investigation. This study aims to investigate the differential effects of AR and VR on users’ simulator sickness, engagement, mental workload, and performance, and usability of the training environment. A training module was developed in Unity 3D for both AR and VR focusing on 3D printing using a powder bed fusion (PBF) printer. A within-subject assignment of factors explored the comparison of ten participants’ experiences regarding simulation sickness and printing experiences and performances. Each participant went through the same tasks under simulated environments to explore the implications of AR and VR on user experience. The study found that there was no statistically significant difference in motivation and user experiences between AR and VR using Meta Quest 3. Moreover, the users experienced comparatively higher simulator sickness in VR than in AR. These findings will not only help to fill the gaps in comparative studies of AR and VR but will also help to inform future technological deployments in educational and professional training scenarios.
