• 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.

Слайд 3

• 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)

WHAT IS VIRTUAL REALITY?

Слайд 4

Sensorama by Morton Heilig in 1962 • Displayed stereoscopic 3D

images in a wide-frame view • Supplied stereo sound

EARLY INVENTIONS IN VR FIELD

Слайд 5

• First virtual reality head-mounted display • Supported head tracking

Sword Of Damocles by Ivan Sutherland in 1968

Слайд 6

• First consumer head-mounted display • Displayed colour graphics • Used

hand gestures to interact with a virtual world

The Eyephone in 1984

Слайд 7

• Marketed as the first portable game console that could display

“true 3D graphics” • Monochromatic display • Used oscillating mirrors to create a 3D effect

Nintendo Virtual Boy
released in 1995

Слайд 8

• 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

HOW DOES IT WORK?

Слайд 10

STEREOSCOPIC 3D IMAGES

Слайд 11

• Video is sent to the Oculus Rift via HDMI cable.

• It also includes USB, which carries data and power to the device.

THE CABLE

Слайд 12

• 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

THE POSITIONAL TRACKER

Слайд 13

• 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

THE HEADSET

Слайд 14

• 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

THE COMPONENTS

Слайд 15

• 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.

THE COMPONENTS

Слайд 16

• Its 1920 x 1080 HD resolution delivers a 960 x

1080 display to each eye. • Its refresh rate of 60 Hz keeps things smooth

THE SCREEN

Слайд 17

• 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

THE FEEDBACK LOOP

Слайд 18

• 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.
