David Em became the first artist to produce navigable virtual worlds at NASA's Jet Propulsion Laboratory (JPL) from 1977 to 1984. The Aspen Movie Map, a crude virtual tour in which users could wander the streets of Aspen in one of the three modes (summer, winter, and polygons), was created at the Massachusetts Institute of Technology (MIT) in 1978. https://www.youtube.com/watch?v=ORWsm8qMaZ4&t=1s

In 2010, Palmer Luckey designed the first prototype of the Oculus Rift. This prototype, built on a shell of another virtual reality headset, was only capable of rotational tracking. However, it boasted a 90-degree field of vision that was previously unseen in the consumer market at the time. Distortion issues arising from the lens used to create the field of vision were corrected for by software written by John Carmack for a version of Doom 3. This initial design would later serve as a basis from which the later designs came. In 2012, the Rift is presented for the first time at the E3 gaming trade show by Carmack. In 2014, Facebook purchased Oculus VR for what at the time was stated as $2 billion but later revealed that the more accurate figure was $3 billion. This purchase occurred after the first development kits ordered through Oculus' 2012 Kickstarter had shipped in 2013 but before the shipping of their second development kits in 2014. Zenimax, Carmack's former employer, sued Oculus and Facebook for taking company secrets to Facebook; the verdict was in favour of Zenimax, settled out of court later. https://www.youtube.com/watch?v=MB-ROjqPiUM&t=1s
To create a feeling of immersion, special output devices are needed to display virtual worlds. Well-known formats include head-mounted displays or the CAVE. In order to convey a spatial impression, two images are generated and displayed from different perspectives (stereo projection). There are different technologies available to bring the respective image to the right eye. A distinction is made between active (e.g. shutter glasses) and passive technologies (e.g. polarizing filters or Infitec). https://www.aliexpress.com/item/Insta360-EVO-5-7K-Video-180-3D-VR-Panoramic-360-Camera-for-Android-and-iPhone-XS/32989155438.html
While audio-visual information is most easily replicated in Virtual Reality, active research and development efforts are still being conducted into the other senses. Tactile inputs such as omnidirectional treadmills allow users to feel as though they’re actually walking through a simulation, rather than sitting in a chair or on a couch. Haptic technologies, also known as kinesthetic or touch feedback tech, have progressed from simple spinning-weight “rumble” motors to futuristic ultrasound technology. It is now possible to hear and feel true-to-life sensations along with visual VR experiences. https://www.youtube.com/channel/UCLMLTE5R-LR26VKfnaDQtEA
Expand your media adventures and social gaming communities with accessories and peripherals created for virtual reality. For example, a VR controller offers seamless integration with virtual reality games to give you more control over your virtual environment. Beyond PC gaming, virtual reality experiences also encompass other forms of video. Virtual reality-compatible cameras capable of filming in 360 degrees offer you the chance to view and edit your footage, along with other VR-ready components.
HTC has branched out beyond tethered headsets with the standalone Vive Focus series. Originally launched only in China, the Vive Focus came to North America late last year, and its 6DOF follow-up, the Vive Focus Plus, will see worldwide release later this year. Both are completely self-contained VR headsets similar to the Lenovo Mirage Solo, capable of full motion tracking and room mapping. The Vive Focus headsets are currently being aimed at the enterprise market rather than consumers, emphasizing their ability to offer virtual training and conferencing in a business context. https://www.aliexpress.com/item/Anker-SoundCore-Dual-Driver-Portable-Wireless-Bluetooth-Speaker-with-24-Hour-Playtime-66-Foot-Bluetooth-Range/32718503055.html
As of the end of 2018, the three best selling Virtual Reality headsets were Sony’s PlayStation VR (PSVR), Facebook’s Oculus Rift and the HTC Vive. This was not a surprise, seeing as the same three HMDs had also been best sellers in 2017. 2019 sees the VR landscape broadening with Google, HP, Lenovo, and others looking to grab a piece of the still-burgeoning market. https://www.youtube.com/watch?v=hXnw8gjbk5I&t=1s
The emphasis here is future, as in several years away. That brings us to the second biggest reason the HoloLens and Magic Leap One aren't on this list: They aren't consumer products. Both devices are purely intended as development hardware, so AR software can be made for their platforms. Even the just-announced HoloLens 2, the second iteration of Microsoft's AR headset, is aimed specifically at developers and enterprise users rather than consumers. https://www.aliexpress.com/item/Professional-Double-Head-Metal-Sheet-Cutter-Drill-Attachment-360-Degree-Rotating-Cutting-Head-For-Cutting-Plate/32948224653.html
Virtual Reality’s most immediately-recognizable component is the head-mounted display (HMD). Human beings are visual creatures, and display technology is often the single biggest difference between immersive Virtual Reality systems and traditional user interfaces. For instance, CAVE automatic virtual environments actively display virtual content onto room-sized screens. While they are fun for people in universities and big labs, consumer and industrial wearables are the wild west.
Currently standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates auditory and video feedback, but may also allow other types of sensory and force feedback through haptic technology. https://www.youtube.com/watch?v=3V15IB3pc94&t=1s
