The document discusses augmented reality (AR), which overlays virtual information onto a user's sensory experience, differentiating it from virtual environments. Key aspects covered include display systems, interaction techniques, applications in fields like medicine and defense, and both advantages and disadvantages of AR technology. The conclusion emphasizes AR's potential to enrich real-world experiences while striving to blur the lines between reality and digital enhancement.

3. Concept
 Augmented reality (AR) refers to computer displays that add
virtual information to a user’s sensory perception.
 It is related to a more general concept called mediated reality in
which a view of reality is modified (possibly even diminished
rather than augmented) by a computer.

4. Augmented Reality
• Tracks the ongoing
interactions and combines
the available data on the
go.
• It has additional Tracking
& interactive system.
Virtual Environment
• Creates virtual feel but
has no interactive
experience.
• It has more advanced
Scene generator &
display devices as
compared to AR.

6. Display Systems
 Head Mounted Display (HMD)

7.  Video See-Through Displays
 Direct Projection

8. Interaction Techniques
 Touch
The simplest interaction technique for any technology is
undoubtedly touch. Its best suited with direct projection.

9.  Gesture
All the advanced commands can be efficiently given
to system using gesture inputs.

10.  Speech
Since the commercialization of the systems like
Siri the possibility of enhancement of speech input
has expanded horizon.

11. Applications
Medical
• Image guided surgery.
• Augmented reality can be applied so that the surgical
team can see the CT or MRI data correctly registered
on the patient.
Defense
• Air Force has been using displays in cockpit that
present information to the pilot on the windshield.
Entertainment
• Gaming with a virtual model of the real environment.
• Virtual studio environment (Avatar movie)

12. Advantages
Can increase knowledge and information
People can share experiences with each other in real
time over long distances
Games that provide an even more "real" experience
Things come to life on people's mobile

13. Disadvantages
 Spam and Security
 Social and Real-Time vs. Solitary
 UX (User Experience): Using AR can be inappropriate
in social situations.
 Not affodable

14. Conclusion
 Augmented reality serves the best purpose of adding
information and meaning to the real object or place.
 The goal of AR is to make the system so efficient
that the user wouldn't be able to differentiate
between real and virtual components.
 Augmented Reality has possibilities beyond our
imagination and perception.
