3. INTRODUCTION
 AUGMENTED REALITY (AR) IS A GENERAL TERM FOR A
COLLECTION OF TECHNOLOGIES USED TO BLEND COMPUTER
COMPUTER GENERATED INFORMATION WITH THE VIEWER'S
VIEWER'S NATURAL SENSES.
 REAL-WORLD ENVIRONMENTS CAN INTERACT WITH VIRTUAL
VIRTUAL OBJECTS.

4. What is AR?
A COMBINATION OF A REAL
SCENE VIEWED BY A USER AND A
VIRTUAL SCENE GENERATED BY
A COMPUTER THAT AUGMENTS
THE SCENE WITH ADDITIONAL
INFORMATION.

5. HISTORY
 AUGMENTED REALITY REMINDS OF SUTHERLAND’S WORK IN 1960,
WHICH USED AN HMD TO PRESENT THE 3D GRAPHICS.
 IN THE YEAR OF 1997, AZUMA EXPLAINED THE FIELD OF AUGMENTED
REALITY, ITS ISSUES AND THEY REQUIRE ADVANCEMENTS.
 AFTER THIS, THERE WAS A REVOLUTION IN THE GROWTH AND THE
PROGRESS OF AUGMENTED REALITY.

6. HOW DOES IT WORK?
 USING A MOBILE APPLICATION, A MOBILE PHONE'S CAMERA
IDENTIFIES AND INTERPRETS A MARKER, OFTEN A BLACK AND WHITE
BARCODE IMAGE.
 THE SOFTWARE ANALYSES THE MARKER AND CREATES A VIRTUAL
IMAGE OVERLAY ON THE MOBILE PHONE'S SCREEN, TIED TO THE
POSITION OF THE CAMERA.
 THIS MEANS THE APP WORKS WITH THE CAMERA TO INTERPRET THE
ANGLES AND DISTANCE THE MOBILE PHONE IS AWAY FROM THE
MARKER.

7. AR & VR
 THEY ARE SIMILAR IN THE GOAL OF IMMERSING THE USER,
THOUGH BOTH SYSTEMS DO THIS IN DIFFERENT WAYS.
 AR - USERS CONTINUE TO BE IN TOUCH WITH THE REAL WORLD
WHILE INTERACTING WITH VIRTUAL OBJECTS AROUND THEM.
 VR - USER IS ISOLATED FROM THE REAL WORLD WHILE IMMERSED
IN A WORLD THAT IS COMPLETELY FABRICATED.

8. APPLICATIONS
AR IN MEDICAL SCIENCES
IT CAN BE USED TO
LET A DOCTOR LOOK
INSIDE A PATIENT BY
COMBINING ONE
SOURCE OF IMAGES
SUCH AS X-RAY WITH
VIDEO.

9. AR IN ARCHITECTURE
 TO ENHANCE THE
VISUALIZATION OF THE
CONSTRUCTED BUILDING
AND CREATE LOCAL VIEW
OF THE PROPERTY
BEFORE THE PHYSICAL
BUILDING IS
CONSTRUCTED

10. AR IN EDUCATION
 IMPROVE THE LEARNING
CAPABILITIES OF YOUR CHILD
BY SUPER IMPOSING
TEXT,GRAPHICS,AUDIO AND
VIDEO IN A REAL TIME
ENVIRONMENT

11. AR IN GAMING
 AR PERMITS GAME LOVERS TO EXPERIENCE DIGITAL GAMEPLAY
IN REAL WORLD ENVIRONMENT

12. ADVANTAGES
 IT ENHANCES THE KNOWLEDGE AND DATA OF THE PEOPLE.
 IT AIDS THE PEOPLE IN SHARING THE EXPERIENCES OVER A
LONG DISTANCE.
 THE GAMES OF AUGMENTED REALITY FURNISH MORE REAL
EXPERIENCE.
 IT HAS A FORM OF ESCAPISM.

13. DISADVANTAGES
IT HAS THE FEATURE OF SPAM.
THE AUGMENTED REALITY DOES NOT HAVE THE STRONG
SECURITY FEATURES.
IT ALSO HAS THE PROBLEMS LIKE PERFORMANCE ISSUES,
INTERACTION ISSUES, AND ALIGNMENT ISSUES.

14. ISSUES
PERFORMANCE ISSUES
 REAL TIME PROCESSING OF IMAGES CAN BE A CHALLENGE
CHALLENGE AND OFTEN CAN SLOW DOWN AUGMENTED
REALITY SYSTEMS.
INTERACTION ISSUES
 USERS WITHIN A MIXED ENVIRONMENT BECAUSE OF
AUGMENTED REALITY HAVE DIFFICULTIES INTERACTING WITH
WITH THE ENVIRONMENT AS NORMAL.
ALIGNMENT ISSUES
 PEOPLE WORKING IN AN AUGMENTED REALITY ARE MORE
SENSITIVE TO ALIGNMENT ERRORS. PROPER CALIBRATION AND
AND ALIGNMENT WITH THE REFERENCE FRAME OF THE
WORLD IS CRUCIAL

15. CONCLUSION
 AUGMENTED REALITY IS ANOTHER STEP FURTHER INTO THE
DIGITAL AGE AS WE WILL SOON SEE OUR ENVIRONMENTS
CHANGE DYNAMICALLY EITHER THROUGH A SMARTPHONE,
GLASSES, CAR WINDSHIELDS AND EVEN WINDOWS IN THE NEAR
FUTURE TO DISPLAY ENHANCED CONTENT AND MEDIA RIGHT IN
FRONT OF US.
 THIS HAS AMAZING APPLICATIONS THAT CAN VERY WELL ALLOW
US TO LIVE OUR LIVES MORE PRODUCTIVELY, MORE SAFELY, AND
MORE INFORMATIVELY.
