What is Virtual Reality?

What is Virtual Reality?

“Why shouldn’t people be able to teleport wherever they want” – Palmer Luckey

Virtual Reality (VR) is the greatest performance of illusion known to man. Knowing the science behind it takes nothing from the enjoyment of it’s magic. Transported into a digital world that you can physically interact with, the only limit to what can be done is imagination. Jaron Lanier, one of the early pioneers of VR said “VR is a cross between cinema, jazz and programming”. It is easy to see how the form of VR entertainment and art can excites it’s users in a radical way.

Virtual reality is experienced through a headset, in a way we perceive as natural. Images are shown stereoscopically to each eye through lens. The lens are adjusted for the individual user, before the computer processes the images separately for each eye. The end result leaves us standing in a digital recreation of times square, or on the ocean floor.

Virtual Interaction

 The 3D viewmasters of old projected a fixed image. The way we interact with VR is a huge part of what makes it so special. VR uses your own moving gaze to change what you can see. Since these persistent environments mimic the way we see the physical world, we believe in VR more deeply. Holding a connection with your audience is nothing new, game or movie directors strive for this already, but VR offers the most gripping stage to do that from. For more on this read our Q & A with our head of new technologies, Peter Caddock.

Our sense of touch has merged with technology in recent years. It’s use within VR is a core sense that weaves the experience. Wireless controllers track hand positioning, motion and offer button interfaces. Most experiences and games allow you to reach out and interact with the world to make physical changes. Although not a consumer norm yet the use of a haptic glove matching the movements of the human hand identically is already in development.

The Future of VR

Virtual Reality is developing fast in the areas relating to the human experience. You can already see products appearing, some even for the consumer market. These include smell, motion mapping, taste, audio and even refinements like depth perception and eye tracking. While sense driven technology shapes the way we interact with the digital world, the future will seem ever closer.

Technology, humanity and Virtual Reality are a powerful combination. In conclusion we are on the verge of a social and technological revolution, something that may be akin to the internet, computers or the mobile.

The History of Virtual Reality

The History of Virtual Reality

“With appropriate programming such a display could literally be the Wonderland into which Alice walked.” – Ivan Sutherland

The Early Years

Virtual Reality is a new frontier. It has had many a pioneer claim to have first walked its paths. The concept as we know it, had its first references as early as the 1930’s. The book Pygmalion’s Spectacles by Stanley Weinbaum, contains almost direct references to the headset type VR we are familiar with today. The other late 30’s invention worthy of note was the stereoscopic photo viewers, these were researched by Charles Wheatstone and commercialised by the View-Master a year later in 1939.

The next big step forward was by the 1950s cinematographer Morton Heilig who developed the Sensorama. This large device that looked much like an arcade machine. It gave the viewer access to a variety of experiences, each tailored to include senses. These included smell, sound, wind and a wider angle of viewing to what was currently available. This was shortly followed by the first head mounted display (HMD), which he named the Telesphere Mask in 1960. This device did not track movement but featured stereo sound and still resembles the design of VR today.

The Birth of Interactive Virtual Reality

The 1960s started strongly for VR as it saw two Philco engineers develop the first motion tracking headset. This was designed for the viewing of dangerous military situations via a camera feed. In 1965 Ivan Sutherland published, The Ultimate Display,  theorising about the ultimate directions of VR, linking our physical connection to a world controlled by a computer.

The idea of using the rapidly developing computers, combined with visual displays has been called ‘the blueprint for the concept of VR today’. Ivan went on to develop a device called the ‘Sword of Damocles’, named for the pole that supported it hanging from the ceiling, thus the first computer driven display of its kind was created. The end of the decade saw Myron Kruegere make his mark, developing and researching the first interactivity of a digital environment. This culminated in the shared experience called VIDEOPLACE technology, where people could be miles apart but appear together.

Jumping to the 1980s creation of VPL Labs by Jaron Lanier, virtual reality finally started to gain momentum. VPL began to develop gloves and headsets. Developers used these to create and interact, exploring many amazing things in the virtual world. Many say Jaron was the ‘Father of VR’’ and coined VR as terminology.  The release of the film Tron in 1982 no doubt also helped drive the interest in the virtual world.

Consumer Virtual Reality

After a decade of more accessible VR technology the 90s exploded with interest for VR. 1991 birthed Virtuality Group Arcade Machines, this placed VR technology in front of the general public in a way it had never been before. The film Lawnmower Man by Brett Leonard soon followed, in part about Jaron Lanier (played by Pierce Brosnan) and even featured VPL labs equipment. Sega and Nintendo both attempted to develop consumer products at this time but with limited success due to development complications, the Virtual Boy did make it to market but was not easy to use and sat uncomfortably.

The Matrix in 1999 laid out the bold concept of what the virtual world could be and continues inspire conversation and interest. Rolling into the 21st Century and we now have major companies like Google, Facebook, HTC, Sony, Microsoft investing heavily in a future connected strongly to VR. we can surmise the reasons for this, linking mainly to the leap in affordable effective processing power and the miniaturisation of computing.

In conclusion the next chapter of VR history is likely to explode into the renaissance era of technology. Films like Ready Player One by Steven Spielberg and VR’s fantastical nature itself, lends to an artistic revolution as the first new canvas for media since the computer screen.
