II. CONCEPT OF CONTEXT AWARE AUGMENTED REALITY A. Augmented Reality Basics There are many related definitions and interpretations of the term “Augmented Reality (AR)”, but the basic commonality in all definitions is that there is some synthetic (computer generated) content augmented to the real-world content perceived by an observer (human being), in real-time. We stick to this basic concept while presenting our understanding of the concept of augmented reality. We also realize that the comprehension of “AR” is generally restricted to the visual perception domain – Synthetic objects (2D/3D) augmented to the real world views in real-time.
