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.youtube.com/watch?v=MmCYZZwO3hg&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).[citation needed] https://www.youtube.com/watch?v=slQwVCm0XTc&t=1s
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=zgdo7-RRjgo&t=1s
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. https://www.youtube.com/watch?v=86tl7K_MAmM&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=8COaMKbNrX0&t=1s
Tethered headsets like the Oculus Rift S, the HTC Vive, and the PlayStation VR are physically connected to PCs (or in the case of the PS VR, a PlayStation 4). The cable makes them a bit unwieldy, but putting all of the actual video processing in a box you don't need to directly strap to your face means your VR experience can be a lot more complex. The use of a dedicated display in the headset instead of your smartphone drastically improves image fidelity, and either external sensors or outward-facing cameras on the headset provide full 6DOF movement tracking. https://www.youtube.com/watch?v=BXlnrFpCu0c&t=1s

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.
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.youtube.com/watch?v=BCYhcFVgCKg&t=1s
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
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=IAyWOgcnJTY&t=1s

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.
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=UaXjcIl-6q8&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.youtube.com/watch?v=ZVUfnJipFh0&t=1s


The big upside to Oculus is that its ecosystem is pretty robust. There are over 1,000 apps and games available to you for the Go. Now you're not going to get some of the more high-end experiences, like Robo Recall, but you're not going to be hurting for content. Oculus' home screen is also probably the best in VR, even on the standalone Go. Finally, you're going to get about 1.5 hours of battery life if you're gaming and 2.5 hours if you're watching videos. The basic version comes with 32GB of storage, you camp bump up to 64GB of storage for a cool £50 more. https://www.aliexpress.com/item/BESDER-Mini-360-Degree-VR-Panoramic-Camera-IP-Wifi-Indoor-Widest-Viewing-Angle-Two-Way-Audio/32841853156.html
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.youtube.com/watch?v=VkPnTaHl-0I&t=1s
Samsung’s approach to VR was different right from the beginning, and the Gear VR was an impressive piece of tech when it was first released in November of 2015. The Gear VR was a far more common sight than an Oculus Rift or HTC Vive in 2016 and 2017, largely because Samsung often gave the device away free with the purchase of a Samsung Galaxy smartphone. Samsung’s VR HMD delivers a stripped-down VR experience, using Oculus head-tracking technology in combination with Android smartphones to power mobile VR experiences. Instead of dedicated display technology, lenses allow the phone’s screen to act as a stereoscopic display, making the device simpler and less expensive than other options. Samsung has added hand controllers to the Gear VR experience, bringing it more in line with current VR content. https://www.youtube.com/watch?v=JsuyAIANYnw&t=1s
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. https://www.youtube.com/watch?v=RCXGpEmFbOw&t=1s

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=ViWpM4D5Ktw&t=1s
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.
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. https://www.youtube.com/channel/UC3VBuU-Ywv1qJGXLk05R-Dg
Augmented reality (AR) is a type of virtual reality technology that blends what the user sees in their real surroundings with digital content generated by computer software. The additional software-generated images with the virtual scene typically enhance how the real surroundings look in some way. AR systems layer virtual information over a camera live feed into a headset or smartglasses or through a mobile device giving the user the ability to view three-dimensional images. https://www.youtube.com/watch?v=JI-ectchft8&t=1s
