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
While they can offer a taste of VR, mobile headsets don't provide the full experience. They tend to offer three-degrees-of-freedom (3DOF) motion tracking, following your direction but not your position. They also only come with one motion controller, which is also 3DOF-only. You don't get the same immersiveness you do with six-degrees-of-freedom (6DOF) motion tracking and dual motion controllers, which might be why Google and Samsung have been largely quiet lately about their mobile headsets. The Nintendo Labo VR Kit is its own unique case, but it's more of a novelty for Switch owners. https://www.youtube.com/watch?v=xYemnKEKx0c&t=1s
The exact origins of virtual reality are disputed, partly because of how difficult it has been to formulate a definition for the concept of an alternative existence. The development of perspective in Renaissance Europe created convincing depictions of spaces that did not exist, in what has been referred to as the "multiplying of artificial worlds". Other elements of virtual reality appeared as early as the 1860s. Antonin Artaud took the view that illusion was not distinct from reality, advocating that spectators at a play should suspend disbelief and regard the drama on stage as reality. The first references to the more modern concept of virtual reality came from science fiction. https://www.aliexpress.com/item/Xiaomi-Mijia-Panoramic-Camera-Mi-Sphere-360-Camera-Sports-Cam-Ambarella-A12-23-88MP-Camera-3/32836659846.html
Morton Heilig wrote in the 1950s of an "Experience Theatre" that could encompass all the senses in an effective manner, thus drawing the viewer into the onscreen activity. He built a prototype of his vision dubbed the Sensorama in 1962, along with five short films to be displayed in it while engaging multiple senses (sight, sound, smell, and touch). Predating digital computing, the Sensorama was a mechanical device. Heilig also developed what he referred to as the "Telesphere Mask" (patented in 1960). The patent application described the device as "a telescopic television apparatus for individual use...The spectator is given a complete sensation of reality, i.e. moving three dimensional images which may be in colour, with 100% peripheral vision, binaural sound, scents and air breezes." https://www.aliexpress.com/item/Global-PROTRULY-V10S-Smartphone-360-Degree-26MP-3D-VR-Full-View-Android-7-1-Snapdrago
According to CEO Stanislas Chesnais, the 3DRudder was designed for "existing games where two hands aren't enough [for] VR, where you don't actually have any solutions today to move in a nice way while sitting." A circular device that you control with both feet by tilting in the direction you want to move, the 3DRudder's latency-free design means that response to your movements is instant and requires little thought. "It's like in real life," says Chesnais. "When you do something [like] set the table… you don't think about your feet moving around. Your hands are what matter." https://www.youtube.com/watch?v=LD4XfM2TZ2k&t=1s
If you have compatible phones, these headsets offer functional 3DOF VR experiences for just $60 to $130. You slide your phone into one, put it on your head, and start tapping away with the included remote. It's interesting, but underwhelming next to tethered and 6DOF standalone VR experiences. Perhaps we'll see some 6DOF updates, but we aren't counting on it. https://www.youtube.com/watch?v=EqcdU9wT5EI&t=1s
Virtual reality is most commonly used in entertainment applications such as video gaming and 3D cinema. Consumer virtual reality headsets were first released by video game companies in the early-mid 1990s. Beginning in the 2010s, next-generation commercial tethered headsets were released by Oculus (Rift), HTC (Vive) and Sony (PlayStation VR), setting off a new wave of application development. 3D cinema has been used for sporting events, pornography, fine art, music videos and short films. Since 2015, roller coasters and theme parks have incorporated virtual reality to match visual effects with haptic feedback.
Google and Samsung still offer phone-based VR headsets in the form of the Daydream View and the Gear VR, and even Nintendo has gotten into the game with its Labo VR Kit for the Nintendo Switch. However, these shell-like headsets, which require a phone or some other device physically inserted into them, feel like novelties next to more powerful headsets that can provide more immersive experiences. https://www.youtube.com/watch?v=gFiZ7cZcuQo&t=1s
Fast Five and Star Trek Beyond director Justin Lin put together this short film for Google's Spotlight Story program in 2016, and it's still one of the more ambitious live action VR shorts out there. Lin opts to use 360 cameras to put you in what feels like a big budget blockbuster, with an alien hellbent on chasing you through the subway. It's absolutely thrilling. https://www.youtube.com/watch?v=x88RLbi0kzk&t=1s
Like the Go, you'll need the companion app on your smartphone to set the headset and the controllers up, but it doesn't take very long at all to do. Then you can start downloading apps, games and experiences from the app or through the headset and there's familiar titles here that have already popped up on the pricier Rift. So, Beat Saber, Thumper, Space Pirate Trainer, and Creed: Rise to Glory all make the cut. https://www.aliexpress.com/item/VR-Camera-Build-in-Wifi-Mini-Panoramic-Camera-360-Degree-Waterproof-Sport-Driving-360-Action-Camera/32812534715.html
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).

Independent production of VR images and video has increased by the development of omnidirectional cameras, also known as 360-degree cameras or VR cameras, that have the ability to record 360 interactive photography, although at low-resolutions or in highly-compressed formats for online streaming of 360 video. In contrast, photogrammetry is increasingly used to combine several high-resolution photographs for the creation of detailed 3D objects and environments in VR applications. https://www.youtube.com/watch?v=me5LJSyQvv4&t=1s
It's also got a bunch of doodads to help you customise your mobile experience. Adjust the lenses all you want, click two buttons to interact with your content; pop out the front window in case you ever need to use it for mixed/augmented reality purposes. Speaking of which, Merge now also sells the AR Merge cube, which lets you put mixed reality experiences in the palm of your hand. https://www.youtube.com/watch?v=I7fp4UoJ9PY&t=1s
In 1992, Nicole Stenger created Angels, the first real-time interactive immersive movie where the interaction was facilitated with a dataglove and high-resolution goggles. That same year, Louis Rosenberg created the virtual fixtures system at the U.S. Air Force's Armstrong Labs using a full upper-body exoskeleton, enabling a physically realistic mixed reality in 3D. The system enabled the overlay of physically real 3D virtual objects registered with a user's direct view of the real world, producing the first true augmented reality experience enabling sight, sound, and touch. https://www.youtube.com/watch?v=pMRO2dl9z3w&t=1s

One of the cool things about VR and 360 video is that it can put you in an experience you wouldn't be able to get before. In the case of this video from MythBusters, that's a couple yards away from a postal van filled with explosives. Not only do you get to experience the explosion from the safety of your own home, the video guides you through the explosion frame by frame, millisecond by millisecond. https://www.youtube.com/watch?v=VrI9In6PqCI&t=1s
Virtual Reality (VR) is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences are the availability of content and cheap computing power.

The newest breed of mobile headsets can also be considered "tethered," because instead of inserting your phone into the headset itself, you physically connect your phone with a USB-C cable. Qualcomm has been emphasizing the VR and augmented reality capabilities of its Snapdragon 855 processor, and is promoting a new ecosystem of XR viewers (including both AR and VR devices). These use the aforementioned USB-C connection to run all processing from a smartphone, while keeping the display technology built separately into the VR headset or AR glasses. https://www.youtube.com/watch?v=jLtcPTm5dTg&t=1s
