A virtual environment should provide the appropriate responses – in real time- as the person explores their surroundings. The problems arise when there is a delay between the person’s actions and system response or latency which then disrupts their experience. The person becomes aware that they are in an artificial environment and adjusts their behaviour accordingly which results in a stilted, mechanical form of interaction. https://www.youtube.com/watch?v=d0yGdNEWdn0&t=1s
In medicine, simulated VR surgical environments under the supervision of experts can provide effective and repeatable training at a low cost, allowing trainees to recognize and amend errors as they occur. Virtual reality has been used in physical rehabilitation since the 2000s. Despite numerous studies conducted, good quality evidence of its efficacy compared to other rehabilitation methods without sophisticated and expensive equipment is lacking for the treatment of Parkinson's disease. A 2018 review on the effectiveness of mirror therapy by virtual reality and robotics for any type of pathology concluded in a similar way. Another study was conducted that showed the potential for VR to promote mimicry and revealed the difference between neurotypical and autism spectrum disorder individuals in their response to a two-dimensional avatar. https://www.youtube.com/watch?v=VkPnTaHl-0I&t=1s
Although we talk about a few historical early forms of virtual reality elsewhere on the site, today virtual reality is usually implemented using computer technology. There are a range of systems that are used for this purpose, such as headsets, omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality. https://www.youtube.com/watch?v=iNWHHhIsE00&t=1s
It's not without issues though. We've already discussed VR exercise equipment as a promising concept let down by being such an expensive, bulky and sweaty process. But if you really want to "get in" the game, and you have space, hopping into an Omni could be pretty neat. We've tried it since its early days at CES and it's been able to stick it out through the years, improving the base, harness and shoes to ensure the best possible experience. https://www.aliexpress.com/item/OHCOMICS-Harri-Potter-HP-Harry-HP-Hogwarts-Gryffindor-360-Degrees-Square-Ring-Stand-Mount-Holder-Mobile/32930948974.html
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.
Naming discrepancies aside, the concept remains the same - using computer technology to create a simulated, three-dimensional world that a user can manipulate and explore while feeling as if he were in that world. Scientists, theorists and engineers have designed dozens of devices and applications to achieve this goal. Opinions differ on what exactly constitutes a true VR experience, but in general it should include: https://www.youtube.com/channel/UCokPdW_udDtALG8Rd_u-hdg
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. https://www.youtube.com/watch?v=-FyjEnoIgTM&t=1s
The two images are then stitched together on the computer just after import. The stitched image (looks like the thumbnail for the above video) is called “equirectangular” format and looks like all 360° got compressed into a single 16:9 frame. Viewers and websites such as YouTube and Vimeo can detect this kind of footage in the file metadata and display it in VR form.
Basically, these AR headsets have transparent lenses that let you look at your surroundings, instead of completely replacing your vision with a computer-generated image. They can still project images over whatever you're looking at, but those images are designed to complement and interact with the area around you. You can make a web browser pop up in the middle of a room, for instance, or watch animals run around your coffee table. It's fascinating technology that could hint at the future of computing. https://www.aliexpress.com/item/New-Product-Brazilian-Virgin-Hair-360-Lace-Frontal-Straight-With-Baby-Hair-Lace-Frontal-Wig-360/32733906711.html
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.
The Oculus Rift was the first big name in the current wave of VR, and Oculus is still a major player. The Rift S has a higher resolution than the Vive (but not as high as the Vive Pro or, strangely, the Oculus Quest) and newer and lighter Oculus Touch motion controllers, and doesn't need external sensors to work. It does, however, need DisplayPort; if your PC only has an HDMI output, you might want to hunt for the previous Rift and deal with the extra cables. https://www.youtube.com/watch?v=kzoJcdVVG_I&t=1s
Bottom line, if you're looking for a VR experience that's closer to the Rift and the Vive without the big price tag and the setup, this is the one you want. The room tracking is fantastic, the controllers are the best we've used and while it won't play all of the top end Rift games, there's a good collection of games and experiences to try out already that will hopefully grow over the coming months. https://www.aliexpress.com/item/360-Action-Camera-Panoramic-Ultra-HD-360-Camara-Deportiva-Wifi-Sport-Cam-Driving-VR-Camera/32773401861.html
All this sounds fantastic and amazing, which it is, but it comes with its fair share of challenges when creating this content. Before I jump into those, take a look at the final product I created for the client, so you have a better understanding of what I’m talking about as I go (Note: For best experience, view on phone or tablet. If you’re on a computer, you can still view it just fine, just click and drag around the screen to change your view): https://www.youtube.com/watch?v=LEIg0xceJE4&t=1s
Oculus has both tethered and standalone headsets from the Go, to the Quest, to the Rift S. HTC has the Steam-friendly Vive and the developer-focused Vive Pro. Sony has the PS 4-focused PlayStation VR (that will apparently work with the PlayStation 5 if and when that system comes out), and Microsoft is supporting its Windows Mixed Reality platform with a variety of headsets from different manufacturers.

To a degree, I’ve made it sound harder than it actually is since software has compensated for much of this, but these were some of the questions I was asking when I was first learning. I then started learning that some standard editing procedures could still be done. For example, I can still create image masks in 360°. So in truth, I still stood behind the camera the whole time along with others and gear and then masked myself out with a separate cut of footage showing the empty room. And for the motion graphics, (I use Adobe software) the software has built-in accommodations for editing and viewing in the 3D space so as to create accurate graphics. So in truth, once I learned, it wasn’t that hard, but boy is it time-consuming. https://www.youtube.com/watch?v=FATfO8ScbCI&t=1s

The Oculus Touch controllers have made a world of difference since their arrival. Compared to the other headsets' controllers, they're our favourite – they conform to your hand and allow for some finger recognition, like a thumbs-up. Not just that, but when it comes to games Oculus has come on leaps and bounds. That's been largely helped by some developer cash injections from Facebook, giving us quality, polished titles like Lone Echo and Robo Recall. Room-scale support has been added too, though you'll need to purchase at least one additional sensor to get it to Vive-level tracking, and even then the Vive tracking experience is a little better in our experience. https://www.youtube.com/watch?v=fdNHr_lWIOo&t=1s

By 1994, Sega released the Sega VR-1 motion simulator arcade attraction, in SegaWorld amusement arcades. It was able to track head movement and featured 3D polygon graphics in stereoscopic 3D, powered by the Sega Model 1 arcade system board. Apple released QuickTime VR, which, despite using the term "VR", was unable to represent virtual reality, and instead displayed 360 photographic panoramas. https://www.youtube.com/watch?v=IapStzmiw1w&t=1s
