A person who wishes to experience a learning session via augmented reality would don a pair of see-through glasses that also host two tiny video cameras and a pair of earphones. A tiny computer, perhaps worn on the wrist or around the waist, would recognize the geometry and content of the user's immediate environment and overlay that environment with meaningful images and sounds for a specific purpose.
From the user’s point of view, he or she would apparently see and hear other people, objects, or events taking place right in front of or around them. These augmented perceptions would appear to be completely real. In technical terms, they would be rendered by the wearable computer with light shading that takes into account both the ambient and directional light sources found in the user's immediate environment.
Put simply, the augmented reality system is "projecting" people, objects, environments or other elements onto the environment around you.
