Classification of Beyond-Reality Interaction Techniques in Spatial Human-Computer Interaction

Abstract

In the context of spatial user interfaces for virtual or augmented reality, many interaction techniques and metaphors are referred to as being (super-)natural, magical or hyper-real. However, many of these terms have not been defined properly, such that a classification and distinction between those interfaces is often not possible. We propose a new classification system which can be used to identify those interaction techniques and relate them to reality-based and abstract interaction techniques.
