Слайд 1

Описание слайда:

OCULUS RIFT

Слайд 2

Описание слайда:

• 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

Описание слайда:

• 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)

Слайд 4

Описание слайда:

Sensorama by Morton Heilig in 1962 • Displayed stereoscopic 3D images in a wide-frame view • Supplied stereo sound

Слайд 5

Описание слайда:

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

Слайд 6

Описание слайда:

• First consumer head-mounted display • Displayed colour graphics • Used hand gestures to interact with a virtual world

Слайд 7

Описание слайда:

• Marketed as the first portable game console that could display “true 3D graphics” • Monochromatic display • Used oscillating mirrors to create a 3D effect

Слайд 8

Описание слайда:

• 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

Описание слайда:

Слайд 11

Описание слайда:

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

Слайд 12

Описание слайда:

• 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

Слайд 13

Описание слайда:

• 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

Слайд 14

Описание слайда:

• 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

Слайд 15

Описание слайда:

• 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.

Слайд 16

Описание слайда:

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

Слайд 17

Описание слайда:

• 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

Слайд 18

Описание слайда:

• 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.
