Transcript of Virtual Reality

Present Day Virtual Reality
Developed in 1995 by Nintendo veteran Gunpei Yakoi
The system utilized an HMD that was mounted on a stand rather than strapped to the head.
The Virtual Boy used a monochromatic (red and black) visor that simulated three dimensional view, similar to a simpler version of Virtual Reality.
The console had several flaws including a rushed development period, caused headaches, neck strain and eye strain.
The Virtual Boy
Virtual Reality in the past included many of the aspects modern Virtual Reality tech boasts today, just on a more simplistic level
Invented in 1965 by computer scientist Ivan Sutherland.
He envisioned what would be called the Ultimate Display
Viewed through an HMD and augmented through three-dimensional sound and tactile stimuli.
Tethered to a computer that maintains the world in real time.
Users could manipulate virtual objects in a realistic, intuitive way.
Similar to the Headsight, the camera was adjusted by the user moving their head.
Rather than Virtual Reality, the Ultimate Display is more Augmented Reality (changes already existig environment rather than creating a whole new one)
Ultimate Display
Past Virtual Reality Technology
What is Virtual Reality?
Computer generated simulation of a three dimensional image or environment.
Is interacted with in a seemingly real or physical way.
Uses special electronic equivalent, such as a helmet with a screen inside, or gloves fitted with sensors.
The ability to track a user's motions particularly their head and eye motions.
Correspondingly adjusts the images on the user's display, to reflect the change in perspective.
Many different models of Virtual Reality work in different ways, but typically most VR technology works in the same way
How Does Virtual Reality Work?
The most innovative advancements of virtual reality for the time period was the Headsight.

The Headsight
The Oculus Rift is a high powered gaming peripheral mostly focused towards PC gaming.
Most advanced piece of virtual reality technology readily available to the public.
There are 2 versions of the Oculus Rift currently available: The original Oculus Rift, and the DK2 (Development Kit 2).
The original Oculus Rift is a more publicly available Oculus, while the DK2 is more for game developers.
The Oculus allows stereoscopic three dimensional view, excellent depth, scale, and parallax
Achieved by presenting unique and parallel images for each eye. This is the same way your eyes perceive images in the real world.

Hardware used in Virtual Reality
Virtual Reality
In a virtual reality environment a user experiences immersion
Immersion is experienced through stereoscopic view, and sound
Sensory output from the virtual environment adjusts in real time as a user explores an environment
Graphics are usually handled by graphics cards with the gaming community in mind.
The hardware used in conjunction with Virtual Reality has changed in complexity over the years, but has generally stayed the same.
HMDs (Head Mounted Display) are typically used.
Some form of controller in generally used
Treadmill like devices can sometimes be used as a controller.
In future models, a human may be the only controller needed.
A tracker attached to the HMD is used to track the users movements.
Most VR tech utilized an HMD, usually very big in size.
In the mid 1950's, Morton H Eilig built a single user console titled "Sensorama".
Included stereoscopic display, fans or emitters, stereo speakers and a moving chair.
These devices were used for watching films, rather than using them for immersive video games.
Developed in the 1960's by Philco Corp
The Headsight was the first ever HMD ever developed
The helmet included a screen and tracking system
Linked to a closed circuit camera system.
The intended use for the Headsight was to train soldiers for dangerous situations.
A user could observe a real environment remotely, adjusting the camera angle by moving their head.
Not all Virtual Reality inventions were a success. Nintendo developed a VR console that was a total failure!

Virtual Reality technology has come a long way since the 20th century, the technological range of devices has become much more complex.
Virtual Reality developers today have been producing more immersive technology through more complex HMD's, trackers and controllers.
Several inventions include the Oculus Rift, Google Glass, and the Viruix Omni.

Oculus Rift Specs
The specs included in the Oculus Rift are second to none in the world of Virtual Reality
360 degree head tracking.
Comfortable, lightweight.
The Oculus Rift provides and approximate 160 degree field of view stretching the virtual world beyond your peripheral vision.
Resolution: 12800x800 (640x800 per eye)
Platforms include PC and mobile.
Weight: ~o.22 kilograms
Virtuix Omni
The Virtuix Omni is used in conjunction with the Oculus Rift, and is an incredible advancement in Virtual Reality immersion.
Developed by Jan Goetgeluk in 2013.
A treadmill like device.
Promises a future where players will be able to physically walk, run, jump and crouch.
Players use special shoes bearing pins that slip into the groves of the treadmill.
The Virtuix Omni is compatible with any PC game that uses keyboard input.
Jan Goetgeluk predicts that the Virtuix Omni will hit the mainstream in 2-3 years.

The Future of Virtual Reality
The future of Virtual Reality hold technology far beyond any of the devices we have seen.
Some developers are producing technology that will further immerse a player in the environment they are put in.
Most Virtual Reality technology today is based around gaming peripherals, while future Virtual Reality Technology will be more self contained, all in one, and wireless.
Future Virtual reality models include the GameFace, and Sony's Prohect Morpheus.
GameFace Labs
This VR device focuses more on an all in one gaming experience rather than a peripheral add-on
In development by GameFace Labs.
The HMD runs on an Android operating system.
The display specs are approximately the same as the Oculus Rift (12800x800)
Unlike the Oculus Rift, this device is portable, since it isn't a peripheral.
Along with a VR experience, the GameFace allows an augmented reality experience and has full app support.

Project Morpheus
Sony's PlayStation brand has an HMD in development, which promises Virtual Reality to Console Gamers.
Project Morpheus is currently in development by Sony.
Project Morpheus will most likely be available in early 2015.
This HMD will be compatible with both the PlayStation Vita, and PS4
Features a high field of view, stereoscopic three dimensional view, and low latency.
A current model for third party developers is not yet available.
Project Morpheus
Current Prototype
Morpheus used with PlayStation Move
Conclusion
Many developers believe that the event of Virtual Reality hitting the mainstream is coming closer than we think. Whatever the case, these technologies are some of the most revolutionary technological gaming and entertainment advances since the 20th century.
