VR creates realistic simulated experiences using computer-generated programs, while AR superimposes computer images onto the real world. VR replaces reality with virtual images and immerses the user, whereas AR enhances reality. AR uses sensors, cameras, geotags and software on devices like smartphones and tablets. VR requires head and eye tracking sensors along with HMDs and uses 360 degree video and APIs. Both technologies can be created using development platforms and software and have applications in education, design, shopping, training, medicine, military and more.

2. VR & AR ?
Virtual reality : A technology in which computer – generated
programs that simulates a realistic experience.
Augmented reality : A technology that superimposes a
computer-generated image on user’s view of real world in 3D
structures.

3. AR VS VR
• A realistic experience with a sense.
• Immerse feeling of artificial world in VR but feels the same real
world in AR.
• VR replaces real with artificial where as AR enhances real life
with artificial images.

4. WORKING & REQUIREMENTS OF AR & VR
AR = Sensors + Camera + geotags + software/application
• It also make use of algorithms.
VR = API + Sensors + Application/software + 360 ̊ video.
• It uses head(x, y, z @50 msec), eye(infrared), motion
tracking.

5. SENSORS & TOOLS
Sensors : Gyroscope (360 view), Accelerometer ( speed &
motion), magnetometer (direction of magnetic field).
Tools : Smartphones, Tablets.(AR)
HMD(head mounted display), Gears.

6. HOW TO CREATE ?
AR : ARKit ( apple dev.), ARCore (google dev.), Vuforia,
Tango + 3D modelling software’s.
VR : A 360 ̊ camera and graphic designing software's.

7. APPLICATIONS
Education : A new way to demonstrate things.
Designing : Simple to create and test the design.
Shopping : Spotting the products.
Training : Industrial training takes a new leap.
Medicine : operating & observation at inner organs.
Military : Specifications of weapons & training simulation.
Driving : By using simulation programs.

8. CONCLUSION
Give your imagination a new way to express/feel with technology.
