Presentation by,NIKHITA SREEDHAR

Oculus Rift

A Virtual Reality head-mounted display.

Invented by a VR enthusiast named -

Palmer Luckey

Developed by Oculus VR, a division of facebook.

Virtual Reality

Simulations that provides the experience of a

physical presence

The recreation of human senses (sight, sound,

touch, taste, smell)

Primarily used to simulate real-life or imaginary

scenarios.

Virtual reality is a technology used for interaction with

a computer generated environment.

It is a simulated version of the real environment.

Can be experienced in three dimensions.

Virtual reality and immersion go side by side.

There are several applications for VR.....

Includes-

Movies

Video Games

Education and Training

The Oculus Rift, is true virtual reality which enhance the gameplay experience of the users and

helps users to experience games in 3D.

Oculus Rift

Oculus Rift is a personal virtual reality goggles for

everyone to use.

Ie, A virtual reality head-set that lets players step

inside their favourite games and virtual world.

Completely blocking our view of the real world and

seeing a new digital, virtual world in its place.

Oculus Rift is a lightweight virtual reality headset

that blocks your view of your surroundings and fully

immerses you in a virtual world.

Allows users to feel as if they are in the game.

Is a set of ski goggles- large mobile phone

screens- replaces the glass material.

Screen displays two images side by side- one

for each eye and focus and reshape pictures for

each eye.

Has sensors to monitor head motions and

adjust the image accordingly.

Creates a sensation of looking around a 3D

world.

Low Latency 360 head tracking

Using custom tracking technology.

Allows us to seamlessly look

around the virtual world as we

do in real life.

Subtle movement of our head is tracked using-

gyroscope and accelerometer.

Stereoscopic 3D view

Oculus Rift creates this view with excellent

depth, scale, and parallax

Unlike 3D on a television, this is achieved by

presenting unique and parallel images for each

eye.

Thus creates a more natural and comfortable

experience.

Ultra Wide Field of View

Provides an approximately 110 field of view

stretching the virtual world beyond the

peripheral vision.

The combination of the wide field of view

with head tracking and stereoscopic 3D creates

an immersive VR.

DEVELOPER VERSION

Oculus released two 'development kits'-

DK1 in late 2012

DK2 in mid 2014

To give developers a chance to develop

content in time for the Rift's release

Front view of Oculus Rift

It uses a 5.6 inch LCD display screen with a

resolution of 1280x800 pixels

DK1

Back view of Oculus Rift

Screen is divided into 640x800 pixels per eye, with a

fixed distance between lense centers.

User can view the screen through two lens cup.

Control Box

Used to hook the headset up to the computer.

Include HDMI port, mini USB port, DVI port and

mini DC power connection port

Contain five buttons for controlling contrast,

brightness and power.

DK2Features several improvements over the first

development kit -

higher-resolution (9601080 per eye) low-persistence

OLED display

higher refresh rate

head positional tracking

detachable cable

omission of the need for the external control box

CONSUMER VERSION Is in development- aimed at a general market and

feature improved components.

Features under consideration- Improved head

tracking, positional tracking, higher resolution, and

wireless operation.

Also integrated audio. The headphones will use

HRTF audio so that sounds can be better located in

a three-dimensional space

COMPARISON

System Requirements

The Oculus Rift device and Software

Development Kit (SDK) support Linux, Mac OS

and Windows operating systems.

The Oculus SDK is publicly available and open

source, meaning that anyone can obtain, use

and even modify and distribute the code.

WORKING The Oculus Rift works like a conventional HMD but packs

a few features that make it ideal for gaming. The Rift offers

Impressive head-tracking capabilities

Stereoscopic 3D rendering;

Wide field of view (110, most headsets only offer around

40)

Several inputs (DVI/HDMI and USB).

The Rift uses a 7- inch display

Lenses deflect the light of the two halves of the screen

to the left and right eye

Different distance between the eyes can be adjusted by

software

One of the most important aspects of VR glasses is to

achieve a large field of view as possible

The bigger it is the easier the brain will accept the new

reality and the more insight will be gained

It feels natural to turn your head to get a full

picture and to spot the details better than you

can with a mouse and keyboard.

The most impressive is the stereoscopic 3D

that simply works and its better than a simple

flat look in 3D television

Internal Structure of Oculus Rift

Orientation Tracking

The Oculus Rift headset contains a gyroscope,

accelerometer, and magnetometer.

To determine the orientation of the users head in the real

world- combine the information from these sensors by

process known as sensor fusion.

It is also used to synchronize the users virtual

perspective in real-time.

The data provided by these sensors help to accurately

track and portray yaw, pitch, and roll movements

Position Tracking

Opens new possibilities for more comfortable, immersive

experiences and gameplay elements

DK2 introduces 6-degree-of-freedom position tracking to

the Rift

Underneath the DK2s IR-translucent outer casing is an

array of infrared micro-LEDs, which are tracked in real

space by the included infrared camera

Positional tracking should always correspond 1:1 with the

users movements

The SDK reports a rough model of the users head in

space based on a set of points and vectors

The model is defined around an origin point

Give users the ability to reset the head models origin

point based on where they are sitting and how their Rift

is set up

Head model- simple model of the users head and neck

is useful in accurately translating sensor information

from head movements into camera movements.

The head model is primarily composed of three

vectors.

One vector roughly maps onto the users neck,

which begins at the origin of the position tracking

space and points to the center eye, a point

roughly at the users nose bridge.

Two vectors originate from the center eye, one

pointing to the pupil of the left eye, the other to the

right

Low Persistence

How quickly the displays refresh

DK2 uses a low persistence OLED display to

eliminate motion blur and judder

The goal of the Oculus team is to accomplish

greater resolutions and attain even lower latency

Oculus VR defines latency as the total time

between movement of the users head and the

updated image being displayed on the screen

Reducing latency is critical to a comfortable

and immersive VR experience

One of the unique points that separate Rift from

its competitors is its low latency head tracking

SIMILAR TECHNOLOGIES

Google Glass

Wearable technology with an optical HMD

Developed by Google producing a mass market

ubiquitous computer.

Used to record videos, take pictures, show messages,

find information, show maps, live video sharing etc

Oculus Rift vs Google Glass

Both are a type of HMD

They are completly different- built for different

purpose and for different audience

Oculus Rift is designed explicitly for gaming

purposes

Google glass is built for a more general purpose

of mobility and connectivity

Sonys Project Morpheus

Project Morpheus is the codename for an

upcoming virtual reality headset produced by Sony

Computer Entertainment

It is designed to be fully functional with the Sony

PlayStation 4 and work with the PlayStation Vita

Oculus Rift vs Project Morpheus

Considered to compete with Oculus Rift

Like Oculus Rift, Project Morpheus- designed

primarily for gaming purposes and also both the

products will be targeted to the same audience

Oculus Rift compatible with most popular

games incorporating virtual reality

Project Morpheus appears to suffer from image

persistence, so Oculus Rift wins in this area

The latest Rift delivers a 110 viewing angle

over Morpheus' 100, which means it has a

bigger field of vision

Oculus Rift is for PC and Project Morpheus is

for Play Station 4

The Sixth Sense Technology

Sixth Sense is a wearable gesture based device

Augments the physical world with digital

information

Lets people use natural hand gestures to interact

with that information

Oculus Rift vs Sixth Sense Oculus Rift and Sixth Sense are by no means

competitors

In fact, there is a possibility that both technologies

can work in unison and complement each other.

The introduction of the Oculus Rift virtual reality

headset is a particularly exciting development for

Sixth Sense because the headset is a natural match

for the 3D input devices

ADOPTION

Several titles are playable on rift Games currently with full or partial support include:

Skyrim

Portal 2

Half Life 2

Bioshock

Dhoom 4

Left 4 Dead

MERITS Incredible sense of presence

The ability to visually explore the virtual world

Natural feeling experience

Oculus offer low latency, fast head-tracking

performance

Adjustable focus for near-or-far-sighted gamers

Better gaming experience

Mind-blowing Oculus Rift experiments that reveal

VR's practical potential

The Oculus Rift's official consumer release is still

months away.....

Though the device has huge implications for the

gaming industry, its potential stretches way beyond games

The Rift headset is already promising to transform more

practical fields like tourism, filmmaking, medicine,

architecture, space exploration, and the battlefield

For Remote Interactions Virtual tourism

When Google Street View debuted in 2007, it amazed everybody.

It was the natural next step after satellite map technology,

and the Oculus Rift will drive that evolution one step further.

This helps for those who are physically unable to travel

It could also allow us to explore places of the world that are

inherently dangerous or impossible to reach

Patient care

It can be a real pain for incapacitated or unstable

patients to constantly travel back and forth to doctors and

therapists.

At first, the Oculus Rift could provide a way for doctors

and patients to meet regularly for sessions, but as the

technology advances, it could even allow for remote

examinations.

For Education Classrooms

The Oculus Rift might be the key to provide a

better environment for remote learners.

Combining the virtual tourism, classrooms could

embark on high-tech field trips to foreign lands for

a fraction of the cost.

Creative exploration

The Rift opens up dozens of new ways for

children to explore creative education.

Special learning

The Rift has also shown to be an effective tool

in situations that involve special needs children

or kids with social anxiety

For Training and Simulation

Simulation aspect of the Oculus Rift can be put to

use as a tool for training.

Its one of the more obvious non-gaming

applications for the device, mostly because non-

VR simulations already exist in many fields, but

the quality of simulation is whats important here.

Medicine

A tool for showing student surgeons the perspective of a

surgery-in-progress

Ie, a first persons view of actual surgery is obtained

Its basically just a widescreen video playing in front of your

eyes, with the ability to lean in for a closer view of the action.

But compared to just watching the video on a computer screen,

the Oculus video is arguably better at blocking distractions

It shows you exactly what the operating surgeon was seeing

during real-world procedures

For Architecture and Modeling Architecture

The Oculus Rift allows architects to build and explore their

creations in a virtual environment without the need for any

physical resources.

The idea is to let architects create their building plans

Upload them into the Oculus Rift-based platform

Then walk through the building or landscape and experience

their designs before pouring a single slab of concrete.

Modeling

Virtual sculpting is another way in which the

Rift provides an outlet for creative exploration

The virtual environment allows for a unique

approach to 3D modeling, which has

implications for digital art

DISADVANTAGES

Not a wireless device

Heavy weight

CONCLUSION

Oculus Rift enhance the gameplay experience

of the users

Oculus Rift helps user to experience games in

3D

Allows to experience the virtual word from your

own living room
