Virtual Reality Setup to Assess Space-Time Geometry Effects on Retrospective Temporal Perception

Abstract This pilot study introduces an innovative approach to researching time perception in virtual reality (VR) by utilizing the Neos Metaverse Engine to design an experimental setup. Participants engaged in trials to assess how Euclidean and non-Euclidean (equi-affine) geometries affect time perception by observing a dot moving along an elliptical trajectory with varying velocity profiles. The study highlights the potential of VR technology, emphasizing the benefits of developing and running the experimental setup within the Neos Metaverse environment, including its built-in tools that facilitate rapid prototyping, iterative design processes, instant feedback, avatar customization options, a comprehensive inventory system, and versatile export capabilities. The findings demonstrate the feasibility and advantages of using a VR-based system for time perception research, paving the way for more immersive and ecologically valid studies. This method offers a robust framework for future investigations into the influence of geometric properties on retrospective time perception in virtual environments.
