AUGMENTED REALITY :-By superimposing virtual imagery, sound and theoretically even other sensorial enrichment over real-world environments in real-time, augmented reality serves as a tool to ever more enhance a human being’s awareness and performance. Originally developed for military applications, the technology has since been transferred to civilian domains such as the medical field, the automobile or leisure industries and many more. While already in place and constantly receiving improvement, augmented reality still faces many shortcomings that limit its effectiveness and portability.

 Augmented Reality (AR) is a variation of VR.
VR technologies completely immerse a user inside a
synthetic environment. While immersed, the user
cannot see the real world around him.
In contrast, AR allows the user to see the real world,
with virtual objects superimposed upon the real world.
 AR supplements reality, rather than completely replacing
it. It creates the illusion that the virtual and real objects
coexisted in the same space.
 AR can be taken as the "middle ground“ between VR
(completely synthetic) and telepresence (completely real)

An Augmented Reality system generates a
composite view for the user. It’s a combination of the
real scene viewed by the user and a virtual scene
generated by the computer that augmented the
scene with additional information.

Augmented Reality:
 Computing device
augments the real world
scene
 User maintains a sense of
presence in real world
Virtual Reality:
 Totally immersive
environment
 Visual senses are
under control of

Typically, the real-world visual scene in an AR display
is captured by video or directly viewed.
Most current AR displays are designed using see-
through HMDs which allow the observer to view the
real world directly with the naked eye.

User can simultaneously view both the real
world and the virtual world.
Most challenging technique among all AR
techniques.Works very good in limited environment.
