Augmented Reality use cases starting at the

from simplest to complex on the

identification, tracking, and mapping of an indoor or outdoor environment. This
use-case is gaining immense interest because 3D depth cameras are being introduced
at smaller form factors. As in the figure, from bottom to top we have the main use
case segments in AR. Starting with the most basic one is “
Virtual Information
,” the
overlay of text, graphics, or video onto real objects like a virtual instruction manual.
This currently is the most common AR use case (Fig.

).
Examples of
Virtual Information overlay
are in print media, where the docu-
ments and manuals are overlaid with virtual content. Several examples are shown
in Fig.

and in the top left image of Fig.

. The AUDI Interactive manual from
