The first step in the evolution of virtual reality came in the 1830s when Charles Wheatstone invented the stereoscope. This device enabled a person to look at two separate pictures which appeared in 3D when viewed with a stereoscope.
The same principle was used later by Morton Heilig but instead of having two pictures he had one picture split into two sections and each section was shown on a TV screen at different angles, creating the illusion of 3D.
In 1968 Ivan Sutherland created the first head-mounted display (HMD), which was a device that displayed graphics on a monitor and allowed the wearer to look around. He also developed a two-handed controller for moving objects around in 3D, called a “wand”. In 1987 Jaron Lanier, who was working on a virtual reality project for NASA at the time, created a head-mounted display that incorporated goggles with two LCD screens and a motion tracking system.
The wearer could look around by turning their heads and moving objects around in 3D with either an analog joystick or by using their hands. Lanier later created a company called VPL Research, which was the first company to sell VR products for commercial use.
In 1991 Michael Naimark created a head-mounted display that used infrared tracking of the user’s eye movements to create a virtual environment. This led to the development of 3D environments since it allowed users to look around 360 degrees and see objects from different perspectives.
The Oculus Quest 2 is having a bit of a moment. While still the best value VR headset on the market for the majority of players, an August 2022 price hike has increased the final cost to $399 / £399 for the 128GB model, which is $100 / £100 more than the previous $299 / £299 MSRP. This increase is also reflected in the 256GB version, pushing it up to $499 / £499. That’s a considerable blow, especially considering the Quest 2 was the only VR headset catering to this sub-$300 / £300 market particularly well. Still, this remains one of the cheapest mid-range options out there, so if you didn’t manage to scoop up the old price it’s still worth investigating. While we were a little disappointed to find the Oculus Quest 2 felt a little cheaper than its predecessor in the hands, we found it more comfortable in our testing overall. That’s thanks to its lighter form factor (503g vs the original 571g) and the wider surface area of the thumb rest of the controller. We were also impressed by just how much sharper than resolution is once we strapped this headset on. You’re free to roam your surroundings with no limiting tracking area and a super flexible setup overall. This is an all-in-one self-contained unit with a speedy processor and plenty of RAM for today’s games to boot. That means you won’t need to invest in a high-end gaming PC to keep things running smoothly here – you’re all good to go straight out of the box. And it’s difficult to understate just how important that is to Oculus Quest 2’s value. With so many of the best VR headsets costing well over $500 / £500 (and still requiring a separate PC brain to function), packing the tracking features, high-resolution display, 90Hz framerate, and comfortable experience into a sub-$300 / £300 price point are incredibly impressive. We’ve even started seeing more and more Oculus Quest 2 deals entering the marketplace in recent months as well.
“Sacrifices have been made, but it’s an improvement on its predecessor in almost every sense.”
History of VR (Virtual Reality):
1838: Sir Charles Wheatstone was the first to describe stereopsis in 1838 and was awarded the Royal Medal of the Royal Society in 1840 for his explanation of binocular vision, a research which led him to construct the stereoscope. The research demonstrated that the brain combines two photographs (one eye viewing each) of the same object taken from different points to make the image appear to have a sense of depth and immersion (3-dimensional). This technology enabled Wheatstone to create the earliest type of stereoscope. It used a pair of mirrors at 45-degree angles to the user’s eyes, each reflecting a picture located off to the side.
1935: In 1935 American science fiction writer Stanley Weinbaum presented a fictional model for VR in his short story Pygmalion’s Spectacles. In the story, the main character meets a professor who invented a pair of goggles that enabled “a movie that gives one sight and sound taste, smell, and touch. You are in the story, you speak to the shadows (characters) and they reply the story is all about you, and you are in it.”
1956: Cinematographer Morton Heilig created Sensorama, the first VR machine (patented in 1962). It was a large booth that could fit up to four people at a time. It combined multiple technologies to stimulate all of the senses: there was a combined full-color 3D video, audio, vibrations, smell, and atmospheric effects, such as wind. This was done using scent producers, a vibrating chair, stereo speakers, and a stereoscopic 3D screen. Heilig thought that the Sensorama was the “cinema of the future” and he wanted to fully immerse people in their films. Six short films were developed for it.
1960: Heilig also patented the Telesphere Mask which was the first head-mounted display (HMD). This provided stereoscopic 3D images with wide vision and stereo sound. There was no motion tracking in the headset at this point.
1961: Until Headlight was created by Comeau and Bryan, two Philco Corporation engineers. The head sight was the first motion-tracking HMD. It had built-in video screens for each eye and a head-tracking system. However, this wasn’t used for virtual reality; it was developed for the military to allow them to remotely look at hazardous situations. A remote camera imitated the head movements so the user could look around the setting.
1965: Ivan Sutherland, a computer scientist, presented his vision of the Ultimate Display. The concept was of a virtual world viewed through an HMD which replicated reality so well that the user would not be able to differentiate it from actual reality. This included the user being able to interact with objects. This concept featured computer hardware to form the virtual world and to keep it functioning in real-time. His paper is seen as the fundamental blueprint for VR. “The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal. With appropriate programming, such a display could be the Wonderland into which Alice walked.”
1966: Thomas Furness, a military engineer, created the first flight simulator for the Air Force. This assisted in the progression of VR because the military subsequently provided a lot of funding for producing better flight simulators.
1968: Sutherland, with his student Bob Sproull, created the first virtual reality HMD, named The Sword of Damocles. These head mounts connected to a computer rather than a camera and was quite primitive as they could only show simple virtual wire-frame shapes. These 3D models changed perspective when the user moved their head due to the tracking system. It was never developed beyond a lab project because it was too heavy for users to comfortably wear; it had to be strapped in because it was suspended from the ceiling.
1969: Myron Krueger, a computer artist, developed a succession of “artificial reality” experiences using computers and video systems. He created computer-generated environments that responded to the people in them. These projects led to VIDEO PLACE technology which is mentioned later.
1972: General Electric Corporation built a computerized flight simulator that featured a 180-degree field of vision by using three screens surrounding the cockpit.
1975: Krueger’s VIDEO PLACE, the first interactive VR platform, was displayed at the Milwaukee Art Center. It used computer graphics, projectors, video cameras, video displays, and position-sensing technology and it didn’t use goggles or gloves. VIDEO PLACE consisted of dark rooms with large video screens to surround the user in “VR”. The users could see their computer-generated silhouettes imitating their movements and actions – the users’ movements were recorded on camera and transferred onto the silhouette. Also, users in different rooms could interact with other user’s silhouettes in the same virtual world. This encouraged the idea that people could communicate within a virtual world even if they weren’t physically close.
1977: Aspen Movie Map was created by MIT. This program enabled users to virtually wander through Aspen city in Colorado, like with Google Street View. There were three modes: summer, winter, and polygons. It was created using photographs from a car driving through the city. There were no HMDs but it was the use of first-person interactivity and it suggested that VR could transport people to other places.
1979: McDonnell-Douglas Corporation integrated VR into its HMD, the VITAL helmet, for military use. A head tracker in the HMD followed the pilot’s eye movements to match computer-generated images.
1980: StereoGraphics Company created stereo vision glasses.
1982: Sayre gloves were created by Sandin and Defanti. These gloves were the first wired gloves. They monitored hand movements by using light emitters and photocells in the gloves’ fingers. So, when the user moved their fingers the amount of light hitting the photocell varied which then converted the finger movements into electrical signals. This may have been the beginning of gesture recognition. Furness created a working model of a virtual flight simulator, for the military, called the Visually Coupled Airborne Systems Simulator (VCASS).
1983: Jaron Lanier and Thomas Zimmerman founded VPL Research, Inc. This company is known as the first company to sell VR goggles and gloves. They developed a range of VR equipment, such as the DataGlove, EyePhone HMD, and the Audio Sphere.
1986: Furness developed a flight simulator between 1986-1989 known as the Super Cockpit. The training cockpit featured: computer-generated 3D maps, and advanced infrared and radar imagery, and the pilot could see and hear in real-time. The helmet’s tracking system and sensors allowed the pilot to control the aircraft using gestures, speech, and eye movements. Read more about Thomas Furness.
1987: British Aerospace used the HMD similar to Furness’ Super Cockpit and developed the Virtual Cockpit which also featured speech recognition. Jaron Lanier popularized the term “Virtual Reality” while at VPL Research. The VR and graphics-related patents were later bought by Sun Microsystems. The company Dimension International created software that could build 3D worlds on a PC.
1989: Scott Foster founded Crystal River Engineering Inc. after receiving a contract from NASA to develop the audio element of the Virtual Environment Workstation Project (VIEW) – a VR training simulator for astronauts. Through this company, real-time binaural 3D audio processing was developed. Mattel, Inc. released the Power Glove, based on VPL’s DataGlove. The Power Glove was a controller accessory for the Nintendo Entertainment System, but it never took off as it was difficult to use.
1990: Jonathan Waldern exhibited Vitality, a VR arcade machine, at the Computer Graphics 90 exhibition in London.
1991: Antonio Medina, a NASA scientist, designed a VR system to drive the Mars robot rovers from Earth in supposed real-time despite signal delays between the planets. This system is called “Computer Simulated Teleoperation”. The Vitality Group launched Vitality. These were VR arcade machines where gamers could play in a 3D gaming world. This was the first mass-produced VR entertainment system. A Vitality pod featured VR headsets and real-time immersive stereoscopic 3D images. Some of the machines could be networked together for multiplayer games. Eventually, some of the very popular arcade games, like Pac-Man, had VR versions. SEGA announced that they were working on the SEGA VR headset which would be available for the general public to purchase. This headset was meant to be used for arcade games and the Mega Drive console. It had a visor-like look due to the influence of popular films, such as Robocop. LCDs were placed in the visor, as well as stereo headphones and sensors for tracking head movement. However, it was never released even though four games were made for it. One of the explanations for the termination was SEGA’s concern about people injuring themselves as the VR effect was too realistic. However, this seems unlikely due to the limited processing power.
1994: SEGA released SEGA VR-1, a motion simulator arcade machine. VictorMaxx released a VR headset called CyberMaxx.
1995: Nintendo launched the Virtual Boy console which played 3D monochrome video games. It was the first portable console to display 3D graphics. But it was a commercial failure due to: The lack of color graphics lack of software support wasn’t comfortable to use one year later it was discontinued. Affordable home VR headsets were released: Virtual IO released the I-Glasses.VFX1 Headgear was released by Forte.
1997: Georgia Tech and Emory University researchers used VR to create war zone scenarios for veterans receiving exposure therapy for PTSD. This was known-as Virtual Vietnam
2001: SAS Cube was the first PC-based cubic room. It led to Virtools VR Pack.
2007: Google introduced Street View. Immersive Media was identified as the contractor that captured the imagery for four of the five cities initially mapped by Street View, using its patented dodecahedral camera array on a moving car.
2010: Google introduced a stereoscopic 3D mode for Street View. Palmer Luckey, an 18-year-old entrepreneur, created the prototype of the Oculus Rift headset. It featured a 90-degree field of vision, which had never been seen before, and relied on a computer’s processing power to deliver the images. This new development boosted and refreshed interest in VR.
2012: Luckey launched a Kickstarter campaign for the Oculus Rift which raised $2.4 million.
2014: Facebook bought the Oculus VR Company for $2 billion. This was a defining moment in VR’s history because VR gained momentum rapidly after this. Sony announced that they were working on Project Morpheus, a VR headset for the PlayStation 4 (PS4). Google released the Cardboard – a low-cost and do-it-yourself stereoscopic viewer for smartphones. Samsung announced the Samsung Gear VR, a headset that uses a Samsung Galaxy smartphone as a viewer. More people started exploring the possibilities of VR, including adding innovative accessories, for example, Cratesmith, an independent developer, recreated a hoverboard scene from Back to the Future by pairing the Oculus Rift with a Wii balance board.
2015: VR possibilities started becoming widely available to the general public, for example, The Wall Street Journal launched a VR roller coaster that followed the ups and downs of the Nasdaq Stock Market. The BBC created a 360-degree video where users view a Syrian migrant camp. The Washington Post released a VR experience of the Oval Office at the White House Correspondents’ Association Dinner.RYOT, a media company, exhibited Confinement, a short VR film about solitary confinement in US prisons.Etc.Gloveone was successful in its Kickstarter campaign. These gloves let users feel and interact with virtual objects.
2016: By 2016 hundreds of companies were developing VR products. Most of the headsets had dynamic binaural audio. Haptic interfaces were underdeveloped. Haptic interfaces are systems that allow humans to interact with a computer using their touch and movements – like the Gloveone gloves that were being developed. This meant that handsets were typically button-operated.HTC released its HTC VIVE SteamVR headset. This was the first commercial release of a headset with sensor-based tracking which allowed users to move freely in space.
2017: Many companies are developing their own VR headsets, including HTC, Google, Apple, Amazon, Microsoft Sony, Samsung, etc. Sony may be developing a similar location tracking tech to HTC’s VIVE for the PlayStation 4.
2018: At Facebook F8, Oculus demonstrated a new headset prototype, the Half Dome. This is a varifocal headset with a 140 degrees field of vision. Virtual reality has significantly progressed and is now being used in a variety of ways, from providing immersive gaming experiences to helping treat psychological disorders, teaching new skills, and even taking terminally ill people on virtual journeys. VR has many applications and with the rise in smartphone technology, VR will be even more accessible. See other applications of VR
2019: Forbes describes this as The Year Virtual Reality Gets Real. Oculus Quest, Facebook’s standalone headset, created a lot of interest and momentum, selling out in many locations and generating $5 million worth of content sales. The shift from tethered to standalone VR headsets represented a shift within the immersive ecosystem, as standalone headsets are much easier to use for the average consumer. Road to VR reported that the monthly-connected VR headsets on Steam had surpassed 1 million for the first time. Nintendo entered the VR market with the Labo: VR kit for Nintendo Switch on April 12. In March, Beat Saber became the first application to sell over 1 million copies in under a year.
2020: The Oculus Quest 2 was unveiled on September 16, 2020, during the Facebook Connect 7 event. The Quest 2 received mostly positive reviews as an incremental update to the Quest and continues to sell in the millions around the world.
2021: Pico launches the Pico Neo 3 headset, a competitor to the Oculus Quest 2 headset. The Chinese company ByteDance, which owns TikTok, acquired Pico in a push to diversify its business. Facebook (now Meta) plans to spend at least $10 billion this year on Facebook Reality Labs, its metaverse division tasked with creating AR and VR hardware, software, and content.
