Introduction To Oculus Rift and Virtual Reality....History Of Virtual Reality Inventions.

1. OCULUS RIFT

2. OCULUS RIFT
• The Oculus Rift is an upcoming virtual reality head-mounted
display, being developed by Oculus VR
• Oculus Rift was invented by a virtual reality enthusiast named
Palmer Luckey and later developed with the help of John
Cormack.

3. WHAT IS VIRTUAL REALITY?
• Virtual Reality (VR), is a computer-simulated environment that
can simulate physical presence in places in the real world or
imagined worlds.
• Virtual Reality Simulations have widespread uses in the fields of
Fine Arts, Music, Gaming, Military Training, etc.
• It involves the recreation of human senses (sight, sound, touch,
taste, smell)

4. EARLY INVENTIONS IN VR FIELD
• Sensorama by Morton Heilig in 1962
• Displayed stereoscopic 3D images in a wide-frame view
• Supplied stereo sound

5. • Sword Of Damocles by Ivan Sutherland in 1968
• First virtual reality head-mounted display
• Supported head tracking

6. • The Eyephone in 1984
• First consumer head-mounted display
• Displayed colour graphics
• Used hand gestures to interact with a virtual world

7. • Nintendo Virtual Boy released in 1995
• Marketed as the first portable game console that
could display “true 3D graphics”
• Monochromatic display
• Used oscillating mirrors to create a 3D effect

8. OCULUS RIFT
• Uses lenses and a split screen to
display 3D graphics
• It uses a 7 inch LCD display screen with a
resolution of 1280 by 800 pixels.
• Screen is divided into 640 by 800 pixels per
eye, with a fixed distance between lens
centers.
• 110 degree field of view

9. HOW DOES IT WORK?

10. STEREOSCOPIC 3D IMAGES

11. THE CABLE
• Video is sent to the Oculus
Rift via HDMI cable.
• It also includes USB, which
carries data and power to the
device.
11

12. THE POSITIONAL
TRACKER
• Tracking the position of your head
in 3D space is critical to the way
the Rift works.
• One of the ways it achieves this is
with a series of infrared LEDs
embedded in the headset, which
are monitored by a webcam-like
camera placed nearby
12

13. THE HEADSET
• Feed is send into the headset, which connects to your head via
vertical and horizontal straps, with the uppermost strap including
the HDMI and USB cable.
• Further customisation is achieved with two pairs of lenses, which
magnify the screen so it fills your field of view.
13

14. THE COMPONENTS
• Within the headset sits a single custom motherboard, which
includes an ARM (Advanced RISC Machines) processor and control
chips for the LEDs.
• The “Adjacent Reality Tracker" which was developed
independently of the Oculus Rift, but has since become a key
component.
14

15. THE COMPONENTS(CONTD.)
• The ART features a magnetometer, a gyroscope and an
accelerometer, all of which combine to accurately track the rift
across all three dimensions of three-dimensionality.
• The ART can track infinitesimally tiny head movements, even if
you're on a rollercoaster during an earthquake.
15

16. THE SCREEN
• Its 1920 x 1080 HD resolution delivers a 960 x 1080 display to each
eye.
• Its refresh rate of 60 Hz keeps things smooth.
16

17. THE FEEDBACK LOOP
• A huge amount of data is continually sent back and forth between
the positional tracker, the headset, the computer and its software.
• It results in an incredibly smooth VR experience.
• Adjustments such as brightness and contrast are made via Oculus'
software.
• It also includes the ability to calibrate the Rift, set your height and
enter your interpupillary distance (IPD), i.e., the size of the gap
between your pupils.
17

18. THE AUDIO
• Oculus Audio SDK allows the use of Head-Related Transfer
Function (HRTF) technology.
• HRTFs simulate the changes to a sound when it reaches your head
from a point in space.
• It does this by referencing data that represents changes that
would happen to a sound coming from that direction.
