This article discusses and summarizes the meanings and definitions of terms such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality. A framework is proposed to organize these terms, clarifying inconsistencies and confusion in their usage. The article concludes that XR should be seen as a more open approach, AR and VR are fundamentally different experiences, and the experiences can be described on a continuum based on the level of presence.
Augmented Reality (AR), Virtual Reality (VR), Mixed Reality, and Extended Reality (often - misleadingly - abbreviated as XR) are commonly used terms to describe how technologies generate or modify reality. However, academics and professionals have been inconsistent in their use of these terms. This has led to conceptual confusion and unclear demarcations. Inspired by prior research and qualitative insights from XR professionals, we discuss the meaning and definitions of various terms and organize them in our proposed framework. As a result, we conclude that (1) XR should not be used to connote extended reality, but as a more open approach where the X implies the unknown variable: xReality; (2) AR and VR have fundamental differences and thus should be treated as different experiences; (3) AR experiences can be described on a continuum ranging from assisted reality to mixed reality (based on the level of local presence); and (4), VR experiences can be conceptualized on a telepresence-continuum ranging from atomistic to holistic VR.
