What is VR and why use it in research?

This introductory chapter explores the research potential offered by working with VR technology and seeks to demystify VR for non-specialist scholars. Definitions of VR, MR, XR and AR are explored, noting that the focus of the book is on VR as it appears within head-mounted displays. We move on to consider the reasons why researchers may wish to employ VR within their projects, focusing on two main areas: VR as an object of study, and VR as a methodological tool. We also emphasise the significance of VR in generating a strong sense of immersion and presence within virtual environments. Contemporary VR research is situated within a brief history of how the technology has evolved. Finally, we give an overview of the chapters in the remainder of the book.
