The document discusses the Oculus Rift virtual reality headset. It describes how the Oculus Rift uses stereoscopic 3D rendering and a 110 degree field of view to provide an immersive virtual reality experience. It also discusses how the Rift's ultra low latency positional tracking and low persistence allows it to track a user's head movements with no motion blur or lag. The document outlines several key features of the Rift's virtual reality technology and its advantages over other gaming systems in providing a natural and realistic virtual experience.

3. Introduction to Oculus

4. • Oculus Rift was invented by a virtual reality enthusiast named Palmer Luckey.
• The Oculus Rift is an upcoming virtual reality head mounted display, being
developed by Oculus VR, a division of Facebook.
• The Oculus Rift delivers a high-end virtual reality experience at an affordable
price. The Rift is also designed to be as comfortable and lightweight as possible
for long play sessions. The current Oculus Rift development kit is 369g.
• Creates an impression of immense environment with a small physical place –large
field view.
• Visual instinctive gameplay whereby enabling perspective base on head motion.
• Immersive virtual reality gameplay takes help of our brain’s sensor fusion, in
order to provide both realism and presence.
• Low Persistence
• Stable image as you turn - no motion blur
• Rolling shutter latency – Right-to-left – 3ms band of light – Eyes offset temporally
• Positional Tracking

5. Advantages:
The Oculus VR provides Immersive stereoscopic 3D rendering enabling
higher rate of depth into the virtual environment.
Extended diagonal field view of 110degrees provides the realism and
presence into the virtual environment.
The latency and 360 degrees head tracking mechanism enables moving
through rather than tracking dependent upon head gestures.
Refresh rate of 75Hz along with low persistence OLED display, eliminate
motion blur and judder, two of the biggest contributor to simulator
sickness.
The affordability plays a major role, the console is offered at 350$ higher
variance.

6. Immersive stereoscopic 3D rendering:

7. • The Stereoscopic 3D view is a technique for creating the illusion of
depth in an image.
• The Oculus Rift uses Stereoscopic 3D view and allows you to see
excellent depth, scale, and parallax.
• It is achieved by presenting unique and parallel images for each eye,
creating a much more realistic experience ("Next-Gen virtual
reality,").
• The Stereoscopic 3D rendering that is equipped on the Oculus Rift
allows you to feel that you are in the virtual world.

8. Ultra low latency positional tracking and low
persistance:

9. • In order for the consumer to completely feel as if they are in the virtual
world, the Oculus Rift uses a custom tracking technology to provide low
latency 360 degrees head tracking.
• This allows the consumer to look around the game as if he is in real life.
With every movement of the gamer’s head; it is tracked by the use of
sensors into the game and makes the virtual game feel natural.
• Every movement that the consumers head makes it is tracked in real time
and changes the orientation of the observer. This creates the most natural
experience a gamer can have with a headset.
• Low persistence provides rolling shutter( – Right-to-left – 3ms band of light
– Eyes offset temporally)

10. Field view and image synthesis:

11. • Ultra Wide Field of View The Oculus Rift provides an approximately 110°
field of view, stretching the virtual world beyond your peripheral vision.
Your view of the game is no longer boxed in on a screen and is only limited
by what your eyes can see.
• The combination of the wide field of view with head-tracking and
stereoscopic 3D creates an immersive virtual reality experience.
• Conventional planar projection – GPUs like this because
• Straight edges remain straight
• Planes remain planar after projection
• Synthesis takes “a while” – So we predict the position / orientation – A long
range prediction: ~10-30ms out

12. Conclusion:
• Every gaming company creates a game that will allow the consumer to feel
as if they are in the game.
• Companies try to make the gamer more involved in the game by creating
inventions such as the Wii, PlayStation Move, and Xbox Kinect.
• The Oculus Rift has become very interesting to with its different features,
creating the most possible natural experience for the virtual world
• The Oculus Rift has become an interesting trend in 2013 because of its
capability. There are no other headsets that feature an amazing immersive
stereoscopic 3D rendering, a massive field of view, and a low latency 360-
degree head tracking. The Oculus Rift allows you to experience the virtual
world from your own living room.
