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. 2
- 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) 3
- 4. EARLY INVENTIONS IN VR FIELD • Sensorama by Morton Heilig in 1962 • Displayed stereoscopic 3D images in a wide-frame view • Supplied stereo sound 4
- 5. • Sword Of Damocles by Ivan Sutherland in 1968 • First virtual reality head-mounted display • Supported head tracking 5
- 6. • The Eyephone in 1984 • First consumer head-mounted display • Displayed colour graphics • Used hand gestures to interact with a virtual world 6
- 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 7
- 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 8
- 9. HOW DOES IT WORK? 9
- 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. 18
