Query: Who created the first virtual reality headset?
Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland, with the help of many students including Bob Sproull, created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and 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.
Recently there have been some advances in the field of virtual reality medicine. Virtual reality is a complete immersion of the patient into a virtual world by putting on a headset with an LED screen in the lenses of the headset. This is different from the recent advancements in augmented reality. Augmented reality is different in the sense that it enhances the non-synthetic environment by introducing synthetic elements to the user's perception of the world. This in turn "augments" the current reality and uses virtual elements to build upon the existing environment. Augmented reality poses additional benefits and has proven itself to be a medium through which individuals suffering from specific phobia can be exposed "safely" to the object(s) of their fear, without the costs associated with programming complete virtual environments. Thus, augmented reality can offer an efficacious alternative to some less advantageous exposure-based therapies.
Open Source Virtual Reality (OSVR) is an open-source software project that aims to enable headsets and game controllers from all vendors to be used with any games. It is also a virtual reality headset that claims to be open-source hardware using the OSVR software. However, as of October 2016 electrical hardware source files have not yet been made available. Since August 2018, the firmware files are available The hardware source files that have been released so far are under a proprietary, source-available license.
Still, the technical setup of the 2014 experiments was not feasible yet for a permanent installation. Most of all, mounting a computer on a coaster train would not have worked due to the continuous heavy vibrations; also the usual cable connection of a classical virtual reality headset like the Oculus Rift would have meant a serious safety hazard. Wagner and his team could eventually overcome these problems by deploying so called mobile virtual reality headsets like the Samsung Gear VR, where the entire image generation happens directly inside of the actual headset. The very first virtual reality roller coaster installations have been opened to the public in late 2015, starting at Europa-Park, Germany, followed by Canada's Wonderland and Universal Studios Japan, all of them developed by the startup company VR Coaster, which originated from Wagners Research Group.
VR is most commonly used in entertainment applications such as 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.[48] 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 .[7]
This is a list of virtual reality headsets, which are head-mounted displays used to present virtual reality environments.
In October 2017, Microsoft officially launched Windows Mixed Reality and a lineup of third-party headsets for use with the Windows 10 "Fall Creators Update" (including a launch lineup of headsets from Acer, Dell, HP, and Lenovo, and future products from Asus and Samsung), officially referred to as Windows Mixed Reality immersive headsets. Unlike HoloLens, these devices are only compatible with virtual reality software, but the underlying ecosystem is referred to as Windows Mixed Reality regardless of experience. All Immersive headsets feature integrated motion tracking (eschewing standalone sensors), and contain cameras that can be used to track handheld motion controller accessories, which may be bundled with the headset, or distributed as optional accessories.
The game may be played without a virtual reality headset, but not all functions of the game are accessible in this mode. In virtual reality mode, the game uses full 3D motion via the motion capture system of a virtual reality headset and two hand-held motion controllers. The hub room vaguely resembles the lobby of a YMCA or other recreational center (thus earning the game's title of "Rec Room") with doors that lead to various games and user-generated rooms. Players can explore the space around them within the confines of their physical floor-space, while roaming further by using controller buttons to teleport a short distance, with minimal or no virtual reality sickness. Sliding (so-called “walking”) is also an option, however it poses a higher risk of virtual reality sickness. Motion controllers are required to pick up and handle objects in the game world, including balls, weapons, construction tools, and other objects.
Virtual reality headsets and viewers have also been designed for smartphones. Unlike headsets with integrated displays, these units are essentially enclosures which a smartphone can be inserted into. VR content is viewed from the screen of the device itself through lenses acting as a stereoscope, rather than using dedicated internal displays. Google released a series of specifications and associated DIY kits for virtual reality viewers known as Google Cardboard; these viewers are capable of being constructed using low-cost materials, such as cardboard (hence the naming).
Virtual reality headsets are being currently used as a means to train medical students for surgery. It allows them to perform essential procedures in a virtual, controlled environment. Students perform surgeries on virtual patients, which allows them to acquire the skills needed to perform surgeries on real patients. It also allows the students to revisit the surgeries from the perspective of the lead surgeon.
The Oculus Rift is a virtual reality (VR) head-mounted display created by Palmer Luckey that the company Oculus VR is developing for virtual reality simulations and video games. The HTC Vive is a virtual reality head-mounted display. The headset is produced by a collaboration between Valve and HTC, with its defining feature being precision room-scale tracking, and high-precision motion controllers. The PlayStation VR is the only virtual reality headset for gaming consoles, for the PlayStation 4.
In October 2016 during a hardware event, Microsoft announced that multiple OEMs would release virtual reality headsets for the Windows Holographic platform, based on Microsoft reference designs enabling room-scale virtual reality without external sensors or components. In January 2017, prototypes were presented at Consumer Electronics Show for release later in the year, and Microsoft later announced that it planned to release development kits for such headsets during the Game Developers Conference. These devices would be supported by the Windows 10 "Creators Update". At the Game Developers Conference in 2017, Microsoft stated that it intended to support Windows Mixed Reality headsets on Xbox One in 2018, specifically noting the capabilities of the then-upcoming Xbox One X hardware revision, but the company later stated that it was initially focusing on PC platforms first, and that it wanted to focus on wireless VR solutions for consoles.
Nintendo's Virtual Boy console was released in 1995.[29] Also in 1995, a group in Seattle created public demonstrations of a "CAVE-like" 270 degree immersive projection room called the Virtual Environment Theater, produced by entrepreneurs Chet Dagit and Bob Jacobson.[30] Forte released the VFX1, a PC-powered virtual reality headset in 1995.
Current VR technology most commonly uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary 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.
The virtual reality headset allows the military personnel to interact with virtual reality people to make it feel real. They can talk to one another and do varying actions to make the virtual reality world feel like they are actually in that situation. There are also disadvantages and advantages when military personnel use the headset. The disadvantage is the headset is made for an indoor area, with a cool environment, and away from any heat, so when military personnel have just the headset on, no military equipment, it is not like their basic training. The advantages consist of repeating the situations multiple times and the cost of having the headset is less, due to no military equipment being needed.
A virtual reality headset compatible with the console, tentatively titled the Jaguar VR, was unveiled by Atari at the 1995 Winter Consumer Electronics Show. The development of the peripheral was a response to Nintendo's virtual reality console, the Virtual Boy, which had been announced the previous year. The headset was developed in cooperation with Virtuality, who had previously created many virtual reality arcade systems, and was already developing a similar headset for practical purposes, named Project Elysium, for IBM. The peripheral was targeted for a commercial release before Christmas 1995. However, the deal with Virtuality was abandoned in October 1995. After Atari's merger with JTS in 1996, all prototypes of the headset were allegedly destroyed. However, two working units, one low-resolution prototype with red and grey-colored graphics and one high-resolution prototype with blue and grey-colored graphics, have since been recovered, and are regularly showcased at retrogaming-themed conventions and festivals. Only one game was developed for the Jaguar VR prototype: a 3D-rendered version of the 1980 arcade game "Missile Command", entitled "Missile Command 3D", though a demo of Virtuality's "Zone Hunter" was also created for Jaguar VR demonstrations.

A virtual reality roller coaster is a special kind of amusement park ride attraction, consisting of a roller coaster facility or ride that can be experienced with virtual reality headsets. The first publicly operated virtual reality roller coasters have been opened in late 2015. Since then, several theme parks all over the world have been adapting this technology to extend their existing coaster facilities.
Virtual reality therapy (VRT), also known as virtual reality immersion therapy (VRIT), simulation for therapy (SFT), virtual reality exposure therapy (VRET), and computerized CBT (CCBT), is the use of virtual reality technology for psychological or occupational therapy. Patients receiving virtual reality therapy navigate through digitally created environments and complete specially designed tasks often tailored to treat a specific ailment. Technology can range from a simple PC and keyboard setup, to a modern virtual reality headset. It is widely used as an alternative form of exposure therapy, in which patients interact with harmless virtual representations of traumatic stimuli in order to reduce fear responses. It has proven to be especially effective at treating PTSD. Virtual reality therapy has also been used to help stroke patients regain muscle control, to treat other disorders such as body dysmorphia, and to improve social skills in those diagnosed with autism.
Asian hardware manufacturers like Xion and Kolke have developed inexpensive virtual reality headsets. In late April 2017, the Chinese company Tencent announced it was preparing to launch its virtual reality headset that year.
In 2014, Sony announced Project Morpheus (its code name for PlayStation VR), a virtual reality headset for the PlayStation 4 video game console.[40] In 2015, HTC and Valve announced the virtual reality headset HTC Vive and controllers. The set included tracking technology called Lighthouse, which utilized wall-mounted "base stations" for positional tracking using infrared light.[41][42][43]
Nomadic is a virtual reality (VR) entertainment company based in San Rafael, California. Nomadic partners with film and gaming companies to create virtual reality "arcades", or various commercial brick and mortar locations such as malls and theaters, where participants' tactile and virtual realities are merged. Users wear headsets and computer backpacks to explore virtual environments, and often use physical props as part of the VR narrative. Venues host modular sets that can be easily adapted to accommodate regularly-updated VR content.
Cyber Danganronpa VR: The Class Trial is a free-to-play virtual reality adventure game in the "Danganronpa" series, developed and published by Spike Chunsoft for the PlayStation 4 for use with the PlayStation VR virtual reality headset. It was produced by Yoshinori Terasawa at Spike Chunsoft, who was inspired to create the game after playing Bandai Namco Entertainment's "Summer Lesson".
The virtual reality headset helps with therapy. People with mental health and addiction issues use therapy by virtual reality headsets to help get over these issues. The Virtual Reality Headset helped patients get over fear, anxiety, panic, and acrophobia. One patient was exposed to a virtual spider for 50 minutes a day over the course of a 12 week period. The Virtual Reality Headset also was used for exercising. Many exercising programs and sports games were created. When a patient is going through therapy, the patient has control over the exposure they have. During the exposure, the patients thoughts, feelings, muscle tension, and heart rate are all observed. Virtual Reality has psychological principles from cognitive-behavioral therapies, neurobiology, neurophysiology, existentialism, and psycho dynamic conceptualizations and knowledge in behavioral neuroscience. The Virtual Reality Headset helped patients get some emotional relief from their day-to-day medications.
