This document discusses augmented reality (AR), which combines real and virtual scenes viewed through a device like glasses. AR enhances the real world with computer-generated input, unlike virtual reality which immerses the user in a simulated world. The document outlines how AR works using tracking, computing, and display components. It explores applications of AR in medical, entertainment, military, and engineering fields and limitations like technological and social acceptance challenges.

3. What is Augmented Reality…A combination of a real scene viewed by a user and a virtual scene generated by a computer that augments the scene with additional information.

12. Social Acceptanceconclusion Augmented reality is a term created to identify systems which are mostly synthetic with some real world imagery added such as texture mapping video onto virtual objects. This is a distinction that will fade as the technology improves and the virtual elements in the scene become less distinguishable from the real ones.
