This may seems like a lot of effort, and it is! What makes the development of virtual reality worthwhile? The potential entertainment value is clear. Immersive films and video games are good examples. The entertainment industry is after all a multi-billion dollar one and consumers are always keen on novelty. Virtual reality has many other, more serious, applications as well. https://www.youtube.com/watch?v=pwJXDrBik4I&t=1s
By 2016, there have been at least 230 companies developing VR-related products. Amazon, Apple, Facebook, Google, Microsoft, Sony and Samsung all had dedicated AR and VR groups. Dynamic binaural audio was common to most headsets released that year. However, haptic interfaces were not well developed, and most hardware packages incorporated button-operated handsets for touch-based interactivity. Visually, displays were still of a low-enough resolution and frame rate that images were still identifiable as virtual. https://www.youtube.com/watch?v=rvUzuK0ygI4&t=1s
That same year, Carolina Cruz-Neira, Daniel J. Sandin and Thomas A. DeFanti from the Electronic Visualization Laboratory created the first cubic immersive room, the Cave automatic virtual environment (CAVE). Developed as Cruz-Neira's PhD thesis, it involved a multi-projected environment, similar to the holodeck, allowing people to see their own bodies in relation to others in the room. Antonio Medina, a MIT graduate and NASA scientist, designed a virtual reality system to "drive" Mars rovers from Earth in apparent real time despite the substantial delay of Mars-Earth-Mars signals. https://www.youtube.com/watch?v=mOEyGEGypvs&t=1s
Virtual reality is the creation of a virtual environment presented to our senses in such a way that we experience it as if we were really there. It uses a host of technologies to achieve this goal and is a technically complex feat that has to account for our perception and cognition. It has both entertainment and serious uses. The technology is becoming cheaper and more widespread. We can expect to see many more innovative uses for the technology in the future and perhaps a fundamental way in which we communicate and work thanks to the possibilities of virtual reality.
Microsoft HoloLens is shaping up to be another formidable competitor in the HMD market. Unlike VR tech, Microsoft based their display on holographic technology. The original Hololens was more proof of concept than consumer device, and the recently announced Hololens 2 is again eschewing the public in favor of enterprise/government uses. The Hololens 2 will feature upgraded visuals, including a much-expanded field of view — music to fans of the original device, who settled on the limited FOV as the main drawback of the device. https://www.aliexpress.com/item/0-26mm-9H-tempered-glass-For-iphone-4s-5-5s-6-6s-plus-screen-protector-protective/32502557737.html
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=41RWJgIjlTA&t=1s
After doing this over and over, revision after revision, eventually I have a final draft to export. In the export window, it is important that I ensure the “VR” is still enabled. What this does is put that specification in the metadata file so that sites like YouTube and Vimeo know to play it as 360° VR footage. Then I can upload it and ensure the playback is the way I want it. https://www.aliexpress.com/item/Panoramic-360-VR-1080P-HD-IP-Mini-Human-Body-Camera-Smart-LED-Lights-Cam-Starlight-IR/32958531508.html
There remains a significant amount of confusion about the differences between Virtual Reality, Augmented Reality and Mixed Reality. (Check out our exhaustive primers on Augmented Reality and Mixed Reality for an in-depth look at the differences.) The public seems to think that AR is a phone experience, while only VR requires an HMD. Mixed Reality devices like the Microsoft Hololens use a headset to overlay 3D imagery on top of the real world. Very cool, but not Virtual Reality. https://www.youtube.com/channel/UCYoKN0FOSrHo1qf4ZqlM2CA

The Oculus Go is the least expensive way to jump into virtual reality. At $200 it's pricier than mobile VR headsets, but unlike those headsets, you don't need a compatible (and usually expensive flagship) smartphone to use it. The $200 investment gets you right into a Gear VR-like virtual reality experience, complete with an intuitive controller. It makes some compromises for the price, like using a dated Snapdragon 821 processor and offering only 3DOF motion tracking, but it's still enough to try out Netflix on a virtual theater screen or play Settlers of Catan in VR.
Special input devices are required for interaction with the virtual world. These include the 3D mouse, the wired glove, motion controllers, and optical tracking sensors. Controllers typically use optical tracking systems (primarily infrared cameras) for location and navigation, so that the user can move freely without wiring. Some input devices provide the user with force feedback to the hands or other parts of the body, so that the human being can orientate himself in the three-dimensional world through haptics and sensor technology as a further sensory sensation and carry out realistic simulations. Additional haptic feedback can be obtained from omnidirectional treadmills (with which walking in virtual space is controlled by real walking movements) and vibration gloves and suits.
To fully experience PC games and other software in 3D, you'll need a player or computer that is capable of delivering high-quality graphics to a virtual reality headset. This requires a player or computer with a powerful graphics card and processor. It's also recommended that your computer have at least 8GB of RAM in order to download VR content. The number of VR-ready PCs continues to grow, so you'll have a variety of options to choose from in order to enjoy smooth gameplay, even when running graphics-heavy games. https://www.youtube.com/channel/UC6NkTCJimTbM1KKCHkpL4uw
