There’s a second class of Virtual Reality HMD that is really just a shell with special lens that pairs with a smartphone to deliver a VR experience. These devices can sell for almost nothing (and are often given away free), and deliver a scaled down VR experience that still approaches the immersive experiences generated by much-more expensive hardware. https://www.youtube.com/watch?v=xYz-fDX1bdM&t=1s
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.
In 2016, HTC shipped its first units of the HTC Vive SteamVR headset. This marked the first major commercial release of sensor-based tracking, allowing for free movement of users within a defined space. A patent filed by Sony in 2017 showed they were developing a similar location tracking technology to the Vive for PlayStation VR, with the potential for the development of a wireless headset.
The PlayStation VR is compelling thanks to Sony backing development for it and the affordability and availability of the PlayStation 4 compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles). There are some excellent games on PS VR like Moss, Rez Infinite, and Until Dawn: Rush of Blood, with Sony and other developers working on several more (including Five Nights at Freddy's VR). https://www.youtube.com/watch?v=8ieIar09dRk&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.
Virtual reality, or VR, is a technology that lets you figuratively step inside a computer-generated 3D world. You can explore and sometimes even manipulate objects in that world. Imagine virtually stepping inside a video game, where the game world feels as real as the non-game world. In fact, video games are one of the most exciting and engaging ways to enjoy VR today.
In 2014, Sony announced Project Morpheus (its code name for the PlayStation VR), a virtual reality headset for the PlayStation 4 video game console. 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. Also in 2015, Razer unveiled its open source project OSVR. https://www.aliexpress.com/item/Andoer-360-Degree-Video-Camera-4K-Ultra-HD-WiFi-VR-Camera-Handheld-Panoramic-Video-Camera-with/32894336986.html
The NBA has long been interested in virtual reality and 360 filmmaking, so it's no surprise that it would decide to take one of the most exciting events on All Star Weekend, the Dunk Contest, and turn it into a 360 video. In this case, you'll get to see all the dunks of winner Donovan Mitchell. Sit courtside as this mountain of a man charges to the hoop and seemingly defies the laws of physics. https://www.aliexpress.com/item/1PCS-Transmission-Solenoid-Valve-OEM-46313-3B030-463133B030-9360930002/32835810874.html
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.aliexpress.com/item/4K-Resolution-Lens-1-21mm-Fisheye-Lens-220-Degree-IR-1-2-3-Inch-16MP-M12/32837407907.html
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
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
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=sZvGJjeLUlg&t=1s
A head-mounted display (HMD) more fully immerses the user in a virtual world. A virtual reality headset typically includes two small high resolution OLED or LCD monitors which provide separate images for each eye for stereoscopic graphics rendering a 3D virtual world, a binaural audio system, positional and rotational real-time head tracking for six degrees of movement. Options include motion controls with haptic feedback for physically interacting within the virtual world in a intuitive way with little to no abstraction and an omnidirectional treadmill for more freedom of physical movement allowing the user to perform locomotive motion in any direction.
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. https://www.youtube.com/watch?v=mwENYk66q6M&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=y4oWTABwBEY&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.
VR headsets may regularly cause eye fatigue, as does all screened technology, because people tend to blink less when watching screens, causing their eyes to become more dried out. There have been some concerns about VR headsets contributing to myopia, but although VR headsets sit close to the eyes, they may not necessarily contribute to nearsightedness if the focal length of the image being displayed is sufficiently far away. https://www.aliexpress.com/item/360-Degrees-Car-Speed-Laser-Radar/32925663509.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.youtube.com/watch?v=3V15IB3pc94&t=1s
