characteristics of augmented reality

"Augmented Reality" is a predominantly real-world setting within which a few virtual parts are superimposed to increase the feasible scope or scale of direction of the physical world. Examples have a physician using Virtual Reality to work on a micro level that could not be done with unaided human hands or a pilot with a see-through Head Mounted Display (head mounted display) that overlays maps on the pilot's range of sight to direct directional assistance.

In addition to its use in direction of jet craft and ships, virtual reality has numerous possible military applications including telerobotics for intelligence or (some day) combat operations in dangerous areas. VR-based simulations are also useful for combat training and anti-terrorism scenarios. Linked page Virtual Tours Henderson, Nevada also discusses these concepts.
