The Real in Augmented Reality
What is augmented in Augmented Reality (AR)? This fundamental question has received surprisingly little attention in AR research. In this paper, we review existing views and show how little consensus there is on the topic. Subsequently, we approach the question from a theoretical and technology-independent perspective that focuses on the relationships between the virtual and the real. We consider both spatial as well as content-based augmentations and distinguish between augmented environments, augmented objects, augmented humans, augmented content and augmented perception. We discuss our findings and suggest possible future directions, such as research into multimodal and crossmodal AR.
