So far, Apple has been very cool on VR, but that's slowly starting to change, at least from a software development side. OS X High Sierra enables VR development on three major VR software platforms: Steam, Unity, and Unreal. It also uses Apple's Metal 2 framework, which the company says provides the performance necessary for VR. No plans for any Apple-branded VR headset have been announced—we'll much more likely see Rift or Vive compatibility added to Macs. https://www.youtube.com/watch?v=71JUbb7QT1w&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.[4] 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".[5] 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.[2] The first references to the more modern concept of virtual reality came from science fiction. https://www.aliexpress.com/item/Firecore-3D-12Lines-Laser-Levels-Self-Leveling-360-Horizontal-And-Vertical-Cross-Super-Powerful-Green-Laser/32738065693.html
The Vive Pro sports a 2,880 x 1,600 resolution on a dual-OLED display, up from the Vive's 2,160 x 1,200 resolution. There's also dual cameras on the front that'll help track your hands and a 90Hz refresh rate with 70 sensors, giving you 360-degree head-tracking. It's not a leap to say that the Vive Pro is a monster. This is easily the most advanced VR headset out there, but it's also incredibly expensive, sitting at £799. If you don't need that added clarity, the Vive has all the same tricks. https://www.aliexpress.com/item/Insta360-Nano-360-Degree-Dual-3K-lens-VR-Video-Camera-Real-Time-Seamless-Stitching-for-iPhone/32819111754.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
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.

Originally funded as a Kickstarter project in 2012, and engineered with the help of John Carmack (founder of Id Software, of Doom and Quake fame), Oculus became the early leader in Virtual Reality hardware for video games. Facebook bought Oculus in 2014, and brought the company’s high-end VR HMD to market for consumers. More recently, Oculus has seen success with the lower-price, lower-powered Oculus Go, and 2019 will see the release of multiple new iterations on the hardware, including the tethered Rift S and the stand-alone Oculus Quest.
There are few worse feelings than putting on a VR headset and having someone else's sweat drip down your face. That's why, if you're likely to be sharing your headset with others, we'd recommend some sort of cover. The company VR Cover does exactly what it suggests, selling covers for the Rift, Vive, Gear VR and Windows Mixed Reality headsets. You can get a couple of machine-washable covers or, if you prefer, some cheaper disposable ones.
By the 1980s, the term "virtual reality" was popularized by Jaron Lanier, one of the modern pioneers of the field. Lanier had founded the company VPL Research in 1985. VPL Research has developed several VR devices like the DataGlove, the EyePhone, and the AudioSphere. VPL licensed the DataGlove technology to Mattel, which used it to make the Power Glove, an early affordable VR device.
From the different headsets we've tested, the hardware is sound and the setup is simple, but position tracking isn't as accurate as tethered headsets with external sensors or the Rift S' new outward-facing tracking cameras. Also, the Windows Mixed Reality store doesn't have as many compelling VR experiences as the Rift and SteamVR stores, though you can use SteamVR games on Windows Mixed Reality headsets, again with some software wrestling. https://www.aliexpress.com/item/AUKEY-360-Degree-Universal-Car-Holder-Magnetic-Air-Vent-Mount-Smartphone-Dock-Mobile-Phone-Holder-for/32580819279.html
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
Virtual Reality is a fascinating way to travel using nothing more than the power of technology. With a headset and motion tracking, VR lets you look around a virtual space as if you're actually there. It's also been a promising technology for decades that's never truly caught on. That's constantly changing with the current wave of VR products, especially as the biggest names in the industry are starting to really hone and tweak their headsets.
In 2014, Sony announced Project Morpheus (its code name for the PlayStation VR), a virtual reality headset for the PlayStation 4 video game console.[37] In 2015, Google announced Cardboard, a do-it-yourself stereoscopic viewer: the user places their smartphone in the cardboard holder, which they wear on their head. Michael Naimark was appointed Google's first-ever 'resident artist' in their new VR division. The Kickstarter campaign for Gloveone, a pair of gloves providing motion tracking and haptic feedback, was successfully funded, with over $150,000 in contributions.[38] Also in 2015, Razer unveiled its open source project OSVR.
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.

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.aliexpress.com/item/10PCS-RC-Airplane-Module-Mini-360-DC-DC-Buck-Converter-Step-Down-Module-4-75V-23V/32683517524.html

Samsung's Gear VR doesn't look much different year-to-year, but the Korean company has given it enough of a boost to keep it on the top of the mobile VR heap. However, it did skip out on updating it in 2018 and in 2019 (so far), and the 2017 edition is the latest version. It's getting a little long in the tooth, but it does now come with a controller. https://www.aliexpress.com/item/Baseus-Car-Phone-Holder-for-iPhone-8-7-6-5S-360-Degree-GPS-Mobile-Phone-Stand/32850702869.html
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. https://www.aliexpress.com/item/100-OEM-NEW-Power-Supply-for-Xbox-360-Charger-For-xbox-Item-NO-PXB005-Internal-Wholesales/32297418013.html
No, this isn't a VR-ready look into the huge court case between Uber and Waymo. It's a 360 video that lets you see how Google's fleet of self-driving cars sees the world. You'll "sit" right on top of the car's LIDAR systems and view the world as machine vision sees the world, complete with lots of little graphics pointing out absolutely everything in sight. There is no better way to learn about self-driving technology than this. https://www.youtube.com/watch?v=8IQbF0IK-f4&t=1s
In 1991, Sega announced the Sega VR headset for arcade games and the Mega Drive console. It used LCD screens in the visor, stereo headphones, and inertial sensors that allowed the system to track and react to the movements of the user's head.[11] In the same year, Virtuality launched and went on to become the first mass-produced, networked, multiplayer VR entertainment system that was released in many countries, including a dedicated VR arcade at Embarcadero Center. Costing up to $73,000 per multi-pod Virtuality system, they featured headsets and exoskeleton gloves that gave one of the first "immersive" VR experiences.[12] https://www.youtube.com/watch?v=eLbY1W-ursw&t=1s

But the competition is closer than ever. Vive is also excellent (and still offers the best room scale), while the Sony PlayStation VR is a big seller thanks to its significantly lower price and the ubiquity of PlayStation 4 consoles ready to run it. There are now better standalone VR headsets too if you want a hassle-free route to the immersive realms. https://www.youtube.com/watch?v=1udaCG1JiWU&t=1s
Desktop-based virtual reality involves displaying a 3D virtual world on a regular desktop display without use of any specialized positional tracking equipment. Many modern first-person video games can be used as an example, using various triggers, responsive characters, and other such interactive devices to make the user feel as though they are in a virtual world. A common criticism of this form of immersion is that there is no sense of peripheral vision, limiting the user's ability to know what is happening around them. https://www.aliexpress.com/item/Panoramic-Action-Camera-360-Degree-Panorama-Camera-With-WIFI-1-5-HD-Screen-14-Mage-VR/32719151259.html
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.
The Virtual Reality Modelling Language (VRML), first introduced in 1994, was intended for the development of "virtual worlds" without dependency on headsets.[43] The Web3D consortium was subsequently founded in 1997 for the development of industry standards for web-based 3D graphics. The consortium subsequently developed X3D from the VRML framework as an archival, open-source standard for web-based distribution of VR content.[44] WebVR is an experimental JavaScript application programming interface (API) that provides support for various virtual reality devices, such as the HTC Vive, Oculus Rift, Google Cardboard or OSVR, in a web browser.[45] https://www.youtube.com/watch?v=ASwABnJjBkA&t=1s
David Em became the first artist to produce navigable virtual worlds at NASA's Jet Propulsion Laboratory (JPL) from 1977 to 1984.[8] 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=EPyNwTmkvIc&t=1s
At some point the 2.0 Lighthouse sensors will arrive with a new curved design and support to add up to four at once (right now it's just two). Meanwhile, the Vive's Trackers enable you to bring any object into VR, and some developers have already found some creative uses for them. These, combined with the TPCast's wireless adapter, gives the Vive the advantage in the tech battle. However, if you wait a little while you can get your hands on the new Vive Pro Eye, which adds new eye-tracking technology (more on that further below). https://www.youtube.com/watch?v=lTsLkUqDcz0&t=1s

Vuzix Blade is compatible with iOS and Android devices, and will set you back a cool $999. https://www.youtube.com/channel/UCyKa1YNZLio6XfjMR7fw45Q

In 1968, Ivan Sutherland, with the help of his students including Bob Sproull, created what was widely considered to be the first head-mounted display system for use in immersive simulation applications. It was primitive both in terms of user interface and visual realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles.

In projector-based virtual reality, modeling of the real environment plays a vital role in various virtual reality applications, such as robot navigation, construction modeling, and airplane simulation. Image-based virtual reality system has been gaining popularity in computer graphics and computer vision communities. In generating realistic models, it is essential to accurately register acquired 3D data; usually, camera is used for modeling small objects at a short distance. https://www.aliexpress.com/item/2017-newst-HD-3D-360-degree-panoramic-driving-support-syste-Surround-View-System-Bird-View-Panorama/32804279638.html
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.aliexpress.com/item/LED-Display-Smart-Home-Water-Shower-Thermometer-Flow-Self-Generating-Electricity-Water-Temperture-Meter-Monitor-for/32854362335.html

Many other companies are developing Virtual Reality headsets and other peripherals. Upcoming hardware includes the GenBasic Quad HD, StarVR StarOne, Vrgineers XTAL and Pansonite VR Headset. As more and better hardware hits the market, it will continue to power a growing ecosystem of hardware manufacturers, software developers, and content providers. https://www.youtube.com/watch?v=sh9giaTKbv4&t=1s
When it comes to moving your feet, most peripherals are stuck in traditional gaming mode: You jump with 'A' or use a joystick to walk, ignoring immersive motion from the waist down. Believing VR should have some more mobility options, the folks at 3DRudder created a VR footpad that allows the user to control all movement – horizontal, vertical and turning – using only their feet. (No word on realistically jerky jumping as of yet, though.)

Leap Motion has been around for a while but now it's got a new lease of life as a VR peripheral compatible with both the Rift and HTC Vive. It attaches with an add-on mounted to the front of the headset and adds hand gesture controls to your virtual reality gaming. It's super precise, tracking each finger – the question is, how precise are your dumb human hands? https://www.youtube.com/watch?v=HcVv9R1ZR84&t=1s
Answering “what is virtual reality” in technical terms is straight-forward. Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions. https://www.youtube.com/watch?v=UMq6DhHdRN4&t=1s
Standalone headsets were at first a useful novelty that offered a taste of VR without an investment into a gaming PC or a flagship phone. The Oculus Go and the Lenovo Mirage Solo are both capable headsets that work well on their own, but they have the same limited controls as mobile headsets. The recently released Oculus Quest, however, has really sold us on this category. The Quest uses similar outward-facing cameras to the new Rift S to provide 6DOF motion tracking, and uses the same Oculus Touch motion controls. Combined with a faster Snapdragon 835 processor compared with the Oculus Go's Snapdragon 821, the Quest offers a much more compelling and immersive VR experience, all without the unwieldy cable or PC requirement of the Rift S. We hope to see more standalone 6DOF, dual motion controller headsets in the future, like the upcoming HTC Vive Focus Plus.
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.

Bees are, like, super important to how our ecologies work. You probably learned all of this in elementary school, but have you ever seen the process, from beginning to end?

By 1994, Sega released the Sega VR-1 motion simulator arcade attraction,[18][19] 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.[20] Apple released QuickTime VR, which, despite using the term "VR", was unable to represent virtual reality, and instead displayed 360 photographic panoramas. https://www.aliexpress.com/item/Rxy-360-Lace-Frontal-Wigs-For-Black-Women-Straight-Pre-Plucked-100-Human-Hair-Wig-With/32810709791.html

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.[13][14] 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.[15] https://www.youtube.com/watch?v=mOEyGEGypvs&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.[16][17] https://www.aliexpress.com/item/LINGCHEN-Car-Phone-Holder-360-Rotation-Holder-for-Phone-in-Car-Air-Vent-Mount-Car-Holder/32862359004.html
Magic Leap has been an investor and media darling since 2014, when Google dumped $540 million in seed money into its sizable coffers. The company has been a source of much fascination and hand-wringing by industry observers ever since. Magic Leap fed the public appetite for information with a string of vaporware demos before finally unveiling the Magic Leap One in 2018. Instead of a magical breakthrough device, the Magic Leap One was more of an updated Hololens, which produced good (but not great) 3D imagery that mixed decently (but not spectacularly) with the real world. The Magic Leap One remains more of a developer tool in search of a consumer application — much like the Hololens. Despite all the doubts now surrounding the company and their technology, Magic Leap’s presence in the industry continues to challenge well-established brands, making them an unusual, but a noteworthy company.

In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double,[2] is the earliest published use of the term "virtual reality". The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s. The term "virtual reality" was first used in a science fiction context in The Judas Mandala, a 1982 novel by Damien Broderick. https://www.aliexpress.com/item/Insta360-ONE-X-Sports-Action-Camera-Insta-360-One-X-5-7K-VR-Video-Panoramic-Camera/32954757912.html
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. https://www.youtube.com/watch?v=rOaG-ICXq0k&t=1s

One place Microsoft has succeeded in how easy it is to set up its WMR headsets. It uses inside-out tracking, so you won't need to go plug in a bunch of sensors to make sure your headset is being seen. These headsets have built-in cameras and sensors that handle all of that. They'll even track the Windows Mixed Reality controllers, which suffer a bit because they rely on the headset being able to see them clearly to properly track. https://www.aliexpress.com/item/Insta360-ONE-X-Sports-Action-Camera-5-7K-Video-VR-360-For-iPhone-and-Android/32944157625.html
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. https://www.aliexpress.com/item/Mini-CCD-HD-Night-Vision-360-Degree-Car-Rear-View-Camera-Front-Camera-Front-View-Side/1539864047.html
The HTC Vive has been one of the best VR HMDs on the market since its consumer release back in 2016. Manufactured by HTC, the Vive was the first VR HMD to support SteamVR. The Vive has been locked in fierce competition with the Oculus Rift since release, as both headsets aimed at the same top end of the VR enthusiast market. The Vive has proven itself a durable workhorse for enterprise solutions, while also delivering one of the best consumer VR experiences available. The Vive was first released back in 2016, and has gone through several iterations, with the addition of a wireless module. The Vive Pro came out in 2018 and the Vive Pro Eye and the HTC Vive Cosmos are both slated for release in the second half of 2019. https://www.aliexpress.com/item/Insta360-Air-360-Degree-Dual-3K-lens-VR-Video-Camera-Real-Time-Seamless-Stitching-for-Android/32816542852.html
Answering “what is virtual reality” in technical terms is straight-forward. Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions. https://www.youtube.com/watch?v=UMq6DhHdRN4&t=1s

So far, Apple has been very cool on VR, but that's slowly starting to change, at least from a software development side. OS X High Sierra enables VR development on three major VR software platforms: Steam, Unity, and Unreal. It also uses Apple's Metal 2 framework, which the company says provides the performance necessary for VR. No plans for any Apple-branded VR headset have been announced—we'll much more likely see Rift or Vive compatibility added to Macs. https://www.youtube.com/watch?v=CZc87WFsg0A&t=1s


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=xgPHXP6x3kc&t=1s

The trade-off, besides the clunky cables, is the price. The least expensive tethered options are currently around $400. And that's before you address the processing issue; the Rift S and the Vive both need pretty powerful PCs to run, while the PS VR requires a PlayStation 4. If the cost isn't a deal breaker but the cables are, HTC offers a wireless adapter for the Vive, but it requires a desktop PC with a free PCIe slot to work. There are also third-party wireless adapters for the Rift, but we can't guarantee how well they work. https://www.youtube.com/watch?v=rG4jSz_2HDY&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=YJnsXH4Lghs&t=1s
Despite being one of the big three in high-end VR, the PS VR is a noticeable step down from the Rift and Vive. It's got a 120Hz refresh rate, which is higher than the others, but it's not as crisp with its 1920 x 1080 resolution, which means things are a little more blurry. Plus, its PS Move controllers feel very long in the tooth; they're repurposed motion controllers from the days when the Nintendo Wii was popular, and feel very outdated when compared to the Rift's Touch controllers. https://www.youtube.com/watch?v=LrObZ_HZZUc&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.[53] 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.[54] A 2018 review on the effectiveness of mirror therapy by virtual reality and robotics for any type of pathology concluded in a similar way.[55] 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.[56] https://www.aliexpress.com/item/360-Degree-Rotating-Tie-Rack-Belt-Hangers-Scarf-Holder-Hook-for-Closet-Organizers-Home-Hanging-Necktie/32962345186.html
In 1979, Eric Howlett developed the Large Expanse, Extra Perspective (LEEP) optical system. The combined system created a stereoscopic image with a field of view wide enough to create a convincing sense of space. The users of the system have been impressed by the sensation of depth (field of view) in the scene and the corresponding realism. The original LEEP system was redesigned for NASA's Ames Research Center in 1985 for their first virtual reality installation, the VIEW (Virtual Interactive Environment Workstation) by Scott Fisher. The LEEP system provides the basis for most of the modern virtual reality headsets.[9] https://www.aliexpress.com/item/SVPRO-hd-vr-camera-double-720p-virtual-reality-vr-box-android-phone-3d-vision-camcorder-for/32761261760.html

In 2013, Valve Corporation discovered and freely shared the breakthrough of low-persistence displays which make lag-free and smear-free display of VR content possible.[31] This was adopted by Oculus and was used in all their future headsets. In early 2014, Valve showed off their SteamSight prototype, the precursor to both consumer headsets released in 2016. It shared major features with the consumer headsets including separate 1K displays per eye, low persistence, positional tracking over a large area, and fresnel lenses.[32][33] HTC and Valve announced the virtual reality headset HTC Vive and controllers in 2015. The set included tracking technology called Lighthouse, which utilized wall-mounted "base stations" for positional tracking using infrared light.[34][35][36] https://www.youtube.com/watch?v=LD4ryByjVyo&t=1s
HTC's Vive is a comprehensive package that includes a headset, two motion controllers, and two base stations for defining a "whole-room" VR area. It's technically impressive, and can track your movements in a 10-foot cube instead of just from your seat. It also includes a set of motion controllers more advanced than the PlayStation Move. PC-tethered VR systems like the Vive need plenty of power, with HTC recommending at least an Intel Core i5-4590 CPU and a GeForce GTX 970 GPU. https://www.aliexpress.com/item/New-360-Degree-Reflective-Prism-Set-for-Leica-ATR-Total-station-Replaces-MPR122/32918809914.html

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.youtube.com/watch?v=UlQt4HNIFXE&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. https://www.youtube.com/watch?v=APd9Nmcc3nU&t=1s
The more powerful Vive Pro offers a higher-resolution display, outward-facing cameras, and a handful of other enhanced features, but it isn't nearly as compelling as the regular Vive; it costs $300 more, and doesn't include the base stations and motion controllers needed to work, so you effectively need to already have a Vive or spend even more money to get set up with it. If that isn't enough power, the Vive Pro Eye adds built-in eye-tracking to the already advanced headset.
There's no wires here at all and no sensors to unlock the room scale tracking. Instead, you can draw out your VR space using the bundled Touch controllers, which are the same ones included with the Rift. The ability to draw multiple Guardians (as Oculus calls it) means you can freely move from different spaces and the headset will remember your safe VR territory.
From the different headsets we've tested, the hardware is sound and the setup is simple, but position tracking isn't as accurate as tethered headsets with external sensors or the Rift S' new outward-facing tracking cameras. Also, the Windows Mixed Reality store doesn't have as many compelling VR experiences as the Rift and SteamVR stores, though you can use SteamVR games on Windows Mixed Reality headsets, again with some software wrestling. https://www.aliexpress.com/item/Amkov-Mini-360-Video-Camera-V1-Action-Camera-Dual-Image-Stabilization-Mini-Panorama-Camera-360-Degree/32859282955.html

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=y4oWTABwBEY&t=1s


In September 2018, Oculus announced the Oculus Quest, the company’s latest stand-alone VR Headset. The Quest uses motion controllers similar to Oculus Touch, has four wide-angle cameras for positional tracking, and sports resolution of 1600×1440 per eye, with option to adjust the lens spacing. The headset launches first half of 2019 and will list for $399.

By 1994, Sega released the Sega VR-1 motion simulator arcade attraction,[18][19] 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.[20] Apple released QuickTime VR, which, despite using the term "VR", was unable to represent virtual reality, and instead displayed 360 photographic panoramas. https://www.aliexpress.com/item/Z-Flex-Tilt-Tripod-Head-Aluminum-Alloy-Folding-Z-Tilt-Head-360-Rotary-Quick-Release-Plate/32881546188.html

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
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.[13][14] 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.[15] https://www.youtube.com/watch?v=mOEyGEGypvs&t=1s
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.aliexpress.com/item/XM-Panoramic-360-VR-960P-1080P-3MP-HD-IP-Camera-Smart-LED-Lights-Cam-Starlight/32836066891.html
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.[39] https://www.aliexpress.com/item/3D-photo-display-rotating-turntable-360-degree-cake-photography-stand-base/32610711220.html
In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double,[2] is the earliest published use of the term "virtual reality". The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s. The term "virtual reality" was first used in a science fiction context in The Judas Mandala, a 1982 novel by Damien Broderick. https://www.youtube.com/watch?v=7-AQVxgadz0&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.youtube.com/watch?v=zO2LDn8_44M&t=1s

In 2014, Sony announced Project Morpheus (its code name for the PlayStation VR), a virtual reality headset for the PlayStation 4 video game console.[37] In 2015, Google announced Cardboard, a do-it-yourself stereoscopic viewer: the user places their smartphone in the cardboard holder, which they wear on their head. Michael Naimark was appointed Google's first-ever 'resident artist' in their new VR division. The Kickstarter campaign for Gloveone, a pair of gloves providing motion tracking and haptic feedback, was successfully funded, with over $150,000 in contributions.[38] Also in 2015, Razer unveiled its open source project OSVR. https://www.youtube.com/watch?v=ecajlIKwlCg&t=1s

Visuals are delivered via an OLED display that offers 1,440 x 1,660 resolution per eye. There's also a built-in speaker with the option to plug in headphones for a more isolated experience. While the VR experience might be on par with those PC-powered headsets, it's still very good and a big step up from the Oculus Go. Games run nice and smooth, though the smartphone-like processing power does mean some titles can take slightly long to load up. https://www.youtube.com/watch?v=jYtGSt7a-s8&t=1s
In aviation, medicine, and the military, Virtual Reality training is an attractive alternative to live training with expensive equipment, dangerous situations, or sensitive technology. Commercial pilots can use realistic cockpits with VR technology in holistic training programs that incorporate virtual flight and live instruction. Surgeons can train with virtual tools and patients, and transfer their virtual skills into the operating room, and studies have already begun to show that such training leads to faster doctors who make fewer mistakes. Police and soldiers are able to conduct virtual raids that avoid putting lives at risk.
The Fove setup is an 5.7-inch, 1440p display; a 100+ degree field of view; 70fps frame rate; and eye-tracking measured at 120fps. With the redesigned developer kit, gone are the big side panels and quite a lot of the heft of the last prototype design. The company promises the new model offers "dramatically reduced weight, size and overall wearability, as well as better production efficiency." You might have to wait a bit though – Fove hasn't confirmed plans for the consumer version just yet.
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.aliexpress.com/item/GOXAWEE-360-Degrees-Rotary-5-Line-6-Points-Laser-Level-Vertical-Horizontal-3D-Automatic-Self-Leveling/32849026144.html
No conversation about Mixed Reality HMDs is ever complete until someone brings up Apple. Yes, the company has no available or announced devices in this space — but there isn’t a soul following technology trends that doesn’t believe the Cupertino giant isn’t a) working on some kind of AR glasses, b) acquiring companies that make lenses and materials that are perfect for some kind of AR glasses, and c) talking about AR as a transformational technology every time a microphone appears. The rumor mill says Apple’s glasses could appear in 2019, but we have our money on a 2020 launch, alongside a newly redesigned and reimagined iPhone that moves away from the “iPhone X design” for the first time since it launched. Stay tuned. https://www.youtube.com/watch?v=MGO4_8YRKro&t=1s

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.

However, because the Lighthouse sensors need good vantage points to track all your head and hand movements, it means mounting them up high. This makes setup for the Vive a bit convoluted compared to, say, the Rift or PSVR. For the Rift, you can just plop down the sensors on a desk, though to get the same 360 tracking you'll need to buy an extra sensor (the Touch bundle gets you two). However, when you get Lighthouse all ready the effect is next-level – enough to make using the PlayStation VR or Rift feel like a step back at times. https://www.youtube.com/watch?v=YwabP6B_UkE&t=1s

If the last applies to you, you're likely a computer scientist or engineer, many of whom now avoid the words virtual reality even while they work on technologies most of us associate with VR. Today, you're more likely to hear someone use the words virtual environment (VE) to refer to what the public knows as virtual reality. We'll use the terms interchangeably in this article.

Windows Mixed Reality is aimed at creating a more affordable version of high-end VR, and many of the headsets are built to run in two modes: one for PCs with dedicated graphics cards and one for PCs with integrated graphics. Many of these headsets start around $300, but at the top of the pile is the Samsung Odyssey. It has built-in spatial headphones from AKG, two 1400 X 1600 AMOLED displays, and a 110-degree field of view. https://www.youtube.com/watch?v=nORNftIHSAo&t=1s
