Презентация на тему The Oculus Rift

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.

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?

Displayed stereoscopic 3D images in a wide-frame view •

Supplied stereo sound

EARLY INVENTIONS IN VR FIELD

head tracking

Sword Of Damocles by Ivan Sutherland

in 1968

graphics • Used hand gestures to interact with a

virtual world

The Eyephone in 1984

that could display “true 3D graphics” • Monochromatic display

• Used oscillating mirrors to create a 3D effect

Nintendo Virtual Boy
released in 1995

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

via HDMI cable. • It also includes USB, which

carries data and power to the device.

THE CABLE

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

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

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

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

a 960 x 1080 display to each eye. •

Its refresh rate of 60 Hz keeps things smooth

THE SCREEN

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

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.

THE AUDIO

• Left 4 Dead • Skyrim • Half-Life 2

• BioShock • Star Citizen • Elite: Dangerous 20

ADOPTION

not very glass friendly. • Heavy Weight Design. •

High Cost.
