The Martian: Examining Human Physical Judgments across Virtual Gravity Fields

Inferences on enacted understanding: using immersive technologies to assess intuitive physical science knowledge

Purpose

This study aims to advance the proposal to use immersive virtual learning environments to stimulate and reveal deep-seated knowledge about science, giving instructors and researchers unique possibilities for assessing and identifying intuitive physical science knowledge. Aside from the ability to present rich and dynamic stimuli, these environments afford bodily enactment of people’s understanding, which draws less from declarative knowledge stores and more from everyday experiences with the physical world.

Design/methodology/approach

The authors ground their proposal in a critical review of the impact of stimulus and task characteristics of traditional physics inventories. Using a grounded theory approach, the authors present classifications and interpretations of observed bodily enactments of physics understandings in a study where participants enacted their understanding of force and motion of space in an immersive, interactive mixed reality (MR) environment.

Findings

The authors find that instances of these action categories can be interpreted as relating to underlying knowledge, often identified by other studies. The authors thus replicate a number of prior findings, which provide evidence to establish validation for using MR simulation as a tool for identifying people’s physical intuitions.

Research limitations/implications

This study targeted only a few specific physical science scenarios. Further, while a number of key insights about student knowledge came from the analysis, many of the observations are mere leads in need of further investigation and interpretation rather than core findings.

Originality/value

Immersive digital learning environments are primarily used for instruction. The authors propose to use and design them for assessment as well. This paper should prompt more research and development in this direction.

Guidelines for immersive virtual reality in psychological research

Virtual reality (VR) holds immense promise as a research tool to deliver results that are generalizable to the real world. However, the methodology used in different VR studies varies substantially. While many of these approaches claim to use 'immersive VR', the different hardware and software choices lead to issues regarding reliability and validity of psychological VR research. Questions arise about quantifying presence, the optimal level of graphical realism, the problem of being in dual realities and reproducibility of VR research. We discuss how VR research paradigms could be evaluated and offer a list of practical recommendations to have common guidelines for psychological VR research.

Using Virtual Reality to Study Subjective Time in Crowded Versus Uncrowded Environments

Human density in different locations influences time estimation. In this article, we report three experiments investigating whether research in virtual reality (VR) environments would replicate this earlier finding. In our first experiment, 35 participants wore head-mounted VR displays and watched two videos showing a cityscape and a countryside. While watching each video, participants were asked to provide their perceptions of 30 seconds of time passage. Perceived time in the cityscape condition was longer than in the countryside condition. In our second experiment, 43 participants wore head-mounted VR displays and watched two videos showing a crowded and uncrowded Ikebukuro station. While watching these videos, participants were asked to provide their perceptions of 60 seconds of time passage. Perceived time in the crowded condition was longer relative to the uncrowded condition. In our third experiment, 21 participants wore head-mounted displays and watched two videos showing a crowded and uncrowded nature park. While watching the videos, participants were asked to provide their perceptions of 60 seconds of time passage. These repeated findings in VR environments of longer time perception in crowded versus uncrowded conditions were similar to data reported by who examined how location and human density affected subjective time in the real world. We discussed the implications of the VR tool in subjective time research and how people perceive and use VR environments in daily life.
