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
