Comparison of 2D and 3D Views on Educational Virtual Reality Content

Abstract

Virtual reality (VR) techniques are being applied in education. However, there are issues to consider when using VR in schools, such as active student participation without any difficulties. In this study, we conducted an experimental class using a desktop-style VR system in a school and focused on the viewing methods of the colearners in a group work. We examined whether there were differences in educational outcomes between a learner operating with VR and a co-learner viewing in 2D or 3D. Results showed that 2D observations can allow students to learn essential classroom concepts whereas 3D observations could allow students to learn more comprehensively. We concluded that group work activities using VR techniques are highly effective for viewing in 3D and has positive effects even for students who view in 2D; however, it requires consideration to certain health impacts such as visual fatigue.
