77-433: UDE's user interface philosophy is quite different from that of other desktop environments . It is designed to be used very efficiently after a short learning phase. There is no taskbar or desktop panel or equivalent. Windows lack a title bar and as such there are no buttons to close, resize, iconify or maximize windows on the window borders. These buttons are replaced by the so-called hex menu or honeycomb that appears when

154-411: A human–machine interface ( HMI ) that typically interfaces machines with physical input hardware (such as keyboards, mice, or game pads) and output hardware (such as computer monitors , speakers, and printers ). A device that implements an HMI is called a human interface device (HID). User interfaces that dispense with the physical movement of body parts as an intermediary step between the brain and

231-451: 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 an 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. Augmented reality (AR)

308-448: A 90-degree field of vision that was previously unseen in the consumer market at the time. Luckey eliminated distortion issues arising from the type of lens used to create the wide field of vision using software that pre-distorted the rendered image in real-time. This initial design would later serve as a basis from which the later designs came. In 2012, the Rift is presented for the first time at

385-413: A PC-powered virtual reality headset that same year. In 1999, entrepreneur Philip Rosedale formed Linden Lab with an initial focus on the development of VR hardware. In its earliest form, the company struggled to produce a commercial version of "The Rig", which was realized in prototype form as a clunky steel contraption with several computer monitors that users could wear on their shoulders. The concept

462-512: A collection of essays, Le Théâtre et son double . The English translation of this book, published in 1958 as The Theater and its Double , 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 . Widespread adoption of

539-405: A decade. Virtual reality Virtual reality ( VR ) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games ), education (such as medical, safety or military training) and business (such as virtual meetings). VR is one of

616-420: A history going back to 1902 and had already become well-established in newsrooms and elsewhere by 1920. In reusing them, economy was certainly a consideration, but psychology and the rule of least surprise mattered as well; teleprinters provided a point of interface with the system that was familiar to many engineers and users. The widespread adoption of video-display terminals (VDTs) in the mid-1970s ushered in

693-408: A job to a batch machine involved first preparing a deck of punched cards that described a program and its dataset. The program cards were not punched on the computer itself but on keypunches , specialized, typewriter-like machines that were notoriously bulky, unforgiving, and prone to mechanical failure. The software interface was similarly unforgiving, with very strict syntaxes designed to be parsed by

770-459: A real video. Users can select their own type of participation based on the system capability. In projector-based virtual reality, modeling of the real environment plays a vital role in various virtual reality applications, including robot navigation, construction modeling, and airplane simulation. Image-based virtual reality systems have been gaining popularity in computer graphics and computer vision communities. In generating realistic models, it

847-438: A relatively heavy mnemonic load on the user, requiring a serious investment of effort and learning time to master. The earliest command-line systems combined teleprinters with computers, adapting a mature technology that had proven effective for mediating the transfer of information over wires between human beings. Teleprinters had originally been invented as devices for automatic telegraph transmission and reception; they had

924-573: A result on magnetic tape or generate some data cards to be used in a later computation. The turnaround time for a single job often spanned entire days. If one was very lucky, it might be hours; there was no real-time response. But there were worse fates than the card queue; some computers required an even more tedious and error-prone process of toggling in programs in binary code using console switches. The very earliest machines had to be partly rewired to incorporate program logic into themselves, using devices known as plugboards . Early batch systems gave

1001-455: A service that shows panoramic views of an increasing number of worldwide positions such as roads, indoor buildings and rural areas. It also features a stereoscopic 3D mode, introduced in 2010. In 2010, Palmer Luckey designed the first prototype of the Oculus Rift . This prototype, built on a shell of another virtual reality headset, was only capable of rotational tracking. However, it boasted

1078-499: 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

1155-569: 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 . " Virtual " has had

1232-630: A virtual environment. This addresses a key risk area in rotorcraft operations, where statistics show that around 20% of accidents occur during training flights. In 2022, Meta released the Meta Quest Pro . This device utilised a thinner, visor-like design that was not fully enclosed, and was the first headset by Meta to target mixed reality applications using high-resolution colour video passthrough. It also included integrated face and eye tracking , pancake lenses , and updated Touch Pro controllers with on-board motion tracking. In 2023, Sony released

1309-462: A year later) initially required users to log in with a Facebook account in order to use the new headset. In 2021 the Oculus Quest 2 accounted for 80% of all VR headsets sold. In 2021, EASA approved the first Virtual Reality-based Flight Simulation Training Device. The device, made by Loft Dynamics for rotorcraft pilots, enhances safety by opening up the possibility of practicing risky maneuvers in

1386-447: Is a graphical user interface (GUI), which is composed of a tactile UI and a visual UI capable of displaying graphics . When sound is added to a GUI, it becomes a multimedia user interface (MUI). There are three broad categories of CUI: standard , virtual and augmented . Standard CUI use standard human interface devices like keyboards, mice, and computer monitors. When the CUI blocks out

1463-418: Is a general principle in the design of all kinds of interfaces. It is based on the idea that human beings can only pay full attention to one thing at one time, leading to the conclusion that novelty should be minimized. If an interface is used persistently, the user will unavoidably develop habits for using the interface. The designer's role can thus be characterized as ensuring the user forms good habits. If

1540-408: 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

1617-400: Is better described as a direct neural interface . However, this latter usage is seeing increasing application in the real-life use of (medical) prostheses —the artificial extension that replaces a missing body part (e.g., cochlear implants ). In some circumstances, computers might observe the user and react according to their actions without specific commands. A means of tracking parts of

1694-454: Is essential to accurately register acquired 3D data; usually, a camera is used for modeling small objects at a short distance. Desktop-based virtual reality involves displaying a 3D virtual world on a regular desktop display without use of any specialized VR 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

1771-436: Is given a complete sensation of reality, i.e. moving three dimensional images which may be in colour, with 100% peripheral vision, binaural sound, scents and air breezes." In 1968, Harvard Professor 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, called The Sword of Damocles . It

1848-844: Is instead branded as a “ spatial computer ”. In 2024, the Federal Aviation Administration approved its first virtual reality flight simulation training device: Loft Dynamics' virtual reality Airbus Helicopters H125 FSTD —the same device EASA qualified. As of September 2024, Loft Dynamics remains the only VR FSTD qualified by EASA and the FAA. Modern virtual reality headset displays are based on technology developed for smartphones including: gyroscopes and motion sensors for tracking head, body, and hand positions ; small HD screens for stereoscopic displays; and small, lightweight and fast computer processors. These components led to relative affordability for independent VR developers, and led to

1925-420: Is only possible using a three-button mouse. As of 2004, UDE offers only very basic support for keyboard shortcuts. The window manager is uwm (unrelated to the older uwm from 1985 or previous). User interface In the industrial design field of human–computer interaction , a user interface ( UI ) is the space where interactions between humans and machines occur. The goal of this interaction

2002-449: Is the number of senses interfaced with. For example, a Smell-O-Vision is a 3-sense (3S) Standard CUI with visual display, sound and smells; when virtual reality interfaces interface with smells and touch it is said to be a 4-sense (4S) virtual reality interface; and when augmented reality interfaces interface with smells and touch it is said to be a 4-sense (4S) augmented reality interface. The user interface or human–machine interface

2079-492: Is the part of the machine that handles the human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples of the physical part of the Human Machine Interface which we can see and touch. In complex systems, the human–machine interface is typically computerized. The term human–computer interface refers to this kind of system. In the context of computing, the term typically extends as well to

2156-534: Is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems , hand tools , heavy machinery operator controls and process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology . Generally,

2233-550: The E3 video game trade show by John Carmack . In 2014, Facebook (later Meta) purchased Oculus VR for what at the time was stated as $ 2 billion but later revealed that the more accurate figure was $ 3 billion. This purchase occurred after the first development kits ordered through Oculus' 2012 Kickstarter had shipped in 2013 but before the shipping of their second development kits in 2014. ZeniMax , Carmack's former employer, sued Oculus and Facebook for taking company secrets to Facebook;

2310-705: The Meta Quest 3 , the successor to the Quest 2. It features the pancake lenses and mixed reality features of the Quest Pro, as well as an increased field of view and resolution compared to Quest 2. In 2024, Apple released the Apple Vision Pro . The device is a fully enclosed mixed reality headset that strongly utilises video passthrough. While some VR experiences are available on the device, it lacks standard VR headset features such as external controllers or support for OpenXR and

2387-614: The PlayStation VR ), a virtual reality headset for the PlayStation 4 video game console. The Chinese headset AntVR was released in late 2014; it was briefly competitive in the Chinese market but ultimately unable to compete with the larger technology companies. 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

2464-461: The PlayStation VR2 , a follow-up to their 2016 headset. The device includes inside-out tracking, eye-tracked foveated rendering , higher-resolution OLED displays, controllers with adaptive triggers and haptic feedback, 3D audio , and a wider field of view. While initially exclusive for use with the PlayStation 5 console, a PC adapter is scheduled for August 2024. Later in 2023, Meta released

2541-491: The Power Glove , an early affordable VR device, released in 1989. That same year Broderbund 's U-Force was released. Atari, Inc. founded a research lab for virtual reality in 1982, but the lab was closed after two years due to the video game crash of 1983 . However, its hired employees, such as Scott Fisher , Michael Naimark , and Brenda Laurel , kept their research and development on VR-related technologies. In 1988,

2618-662: The Sega VR headset for the Mega Drive home 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. 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

2695-517: The Sensorama in 1962, along with five short films to be displayed in it while engaging multiple senses (sight, sound, smell, and touch). Predating digital computing, the Sensorama was a mechanical device . Heilig also developed what he referred to as the "Telesphere Mask" (patented in 1960). The patent application described the device as "a telescopic television apparatus for individual use... The spectator

2772-688: The VR-1 motion simulator ride attraction in Joypolis indoor theme parks, as well as the Dennou Senki Net Merc arcade game . Both used an advanced head-mounted display dubbed the "Mega Visor Display" developed in conjunction with Virtuality; it was able to track head movement in a 360-degree stereoscopic 3D environment, and in its Net Merc incarnation was powered by the Sega Model 1 arcade system board . Apple released QuickTime VR , which, despite using

2849-609: The Valve Index . Notable features include a 130° field of view, off-ear headphones for immersion and comfort, open-handed controllers which allow for individual finger tracking, front facing cameras, and a front expansion slot meant for extensibility. In 2020, Oculus released the Oculus Quest 2 , later renamed the Meta Quest 2. Some new features include a sharper screen, reduced price, and increased performance. Facebook (which became Meta

2926-416: The stereoscope invented by Sir Charles Wheatstone were both precursors to virtual reality. The first references to the more modern-day concept of virtual reality came from science fiction . Morton Heilig wrote in the 1950s of an "Experience Theatre" that could encompass all the senses in an effective manner, thus drawing the viewer into the onscreen activity. He built a prototype of his vision dubbed

3003-413: 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. By July 1994, Sega had released

3080-466: The 2012 Oculus Rift Kickstarter offering the first independently developed VR headset. Independent production of VR images and video has increased alongside the development of affordable omnidirectional cameras , also known as 360-degree cameras or VR cameras, that have the ability to record 360 interactive photography , although at relatively low resolutions or in highly compressed formats for online streaming of 360 video . In contrast, photogrammetry

3157-668: The Cyberspace Project at Autodesk was the first to implement VR on a low-cost personal computer. The project leader Eric Gullichsen left in 1990 to found Sense8 Corporation and develop the WorldToolKit virtual reality SDK, which offered the first real time graphics with Texture mapping on a PC, and was widely used throughout industry and academia. The 1990s saw the first widespread commercial releases of consumer headsets. In 1992, for instance, Computer Gaming World predicted "affordable VR by 1994". In 1991, Sega announced

3234-719: The basis for most of the modern virtual reality headsets. By the late 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 1984. VPL Research has developed several VR devices like the DataGlove , the EyePhone, the Reality Built For Two (RB2), and the AudioSphere. VPL licensed the DataGlove technology to Mattel , which used it to make

3311-464: The body is required, and sensors noting the position of the head, direction of gaze and so on have been used experimentally. This is particularly relevant to immersive interfaces . The history of user interfaces can be divided into the following phases according to the dominant type of user interface: In the batch era, computing power was extremely scarce and expensive. User interfaces were rudimentary. Users had to accommodate computers rather than

3388-402: The computer pioneers of the 1940s. Just as importantly, the existence of an accessible screen—a two-dimensional display of text that could be rapidly and reversibly modified—made it economical for software designers to deploy interfaces that could be described as visual rather than textual. The pioneering applications of this kind were computer games and text editors; close descendants of some of

3465-446: The consumer headsets including separate 1K displays per eye, low persistence, positional tracking over a large area, and Fresnel lenses . 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. In 2014, Sony announced Project Morpheus (its code name for

3542-423: The currently running job the entire computer; program decks and tapes had to include what we would now think of as operating system code to talk to I/O devices and do whatever other housekeeping was needed. Midway through the batch period, after 1957, various groups began to experiment with so-called " load-and-go " systems. These used a monitor program which was always resident on the computer. Programs could call

3619-512: The designer is experienced with other interfaces, they will similarly develop habits, and often make unconscious assumptions regarding how the user will interact with the interface. Peter Morville of Google designed the User Experience Honeycomb framework in 2004 when leading operations in user interface design. The framework was created to guide user interface design. It would act as a guideline for many web development students for

3696-418: The driver the impression of actually driving a vehicle by predicting vehicular motion based on the driver's input and providing corresponding visual, motion, and audio cues. With avatar image -based virtual reality, people can join the virtual environment in the form of real video as well as an avatar. One can participate in the 3D distributed virtual environment in the form of either a conventional avatar or

3773-589: The earliest specimens, such as rogue (6), and vi (1), are still a live part of Unix tradition. In 1985, with the beginning of Microsoft Windows and other graphical user interfaces , IBM created what is called the Systems Application Architecture (SAA) standard which include the Common User Access (CUA) derivative. CUA successfully created what we know and use today in Windows, and most of

3850-401: The expression graphical user interface for human–machine interface on computers, as nearly all of them are now using graphics. Multimodal interfaces allow users to interact using more than one modality of user input. There is a difference between a user interface and an operator interface or a human–machine interface (HMI). In science fiction , HMI is sometimes used to refer to what

3927-554: The first "immersive" VR experiences. 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

4004-485: The first artist to produce navigable virtual worlds at NASA 's Jet Propulsion Laboratory (JPL) from 1977 to 1984. 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 MIT in 1978. In 1979, Eric Howlett developed the Large Expanse, Extra Perspective (LEEP) optical system. The combined system created

4081-614: 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. In 2019, Oculus released the Oculus Rift S and a standalone headset, the Oculus Quest . These headsets utilized inside-out tracking compared to external outside-in tracking seen in previous generations of headsets. Later in 2019, Valve released

4158-453: The goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability ). This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the user. User interfaces are composed of one or more layers, including

4235-482: The interface design include prototyping and simulation. Typical human–machine interface design consists of the following stages: interaction specification, interface software specification and prototyping: In broad terms, interfaces generally regarded as user friendly, efficient, intuitive, etc. are typified by one or more particular qualities. For the purpose of example, a non-exhaustive list of such characteristics follows: The principle of least astonishment (POLA)

4312-408: The key technologies in the reality-virtuality continuum . As such, it is different from other digital visualization solutions, such as augmented virtuality and augmented reality . Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate some realistic images, sounds and other sensations that simulate a user's physical presence in

4389-639: The machine use no input or output devices except electrodes alone; they are called brain–computer interfaces (BCIs) or brain–machine interfaces (BMIs). Other terms for human–machine interfaces are man–machine interface ( MMI ) and, when the machine in question is a computer, human–computer interface . Additional UI layers may interact with one or more human senses, including: tactile UI ( touch ), visual UI ( sight ), auditory UI ( sound ), olfactory UI ( smell ), equilibria UI ( balance ), and gustatory UI ( taste ). Composite user interfaces ( CUIs ) are UIs that interact with two or more senses. The most common CUI

4466-448: The meaning of "being something in essence or effect, though not actually or in fact" since the mid-1400s. The term "virtual" has been used in the computer sense of "not physically existing but made to appear by software " since 1959. In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in

4543-441: The monitor for services. Another function of the monitor was to do better error checking on submitted jobs, catching errors earlier and more intelligently and generating more useful feedback to the users. Thus, monitors represented the first step towards both operating systems and explicitly designed user interfaces. Command-line interfaces ( CLIs ) evolved from batch monitors connected to the system console. Their interaction model

4620-542: The more recent DOS or Windows Console Applications will use that standard as well. This defined that a pulldown menu system should be at the top of the screen, status bar at the bottom, shortcut keys should stay the same for all common functionality (F2 to Open for example would work in all applications that followed the SAA standard). This greatly helped the speed at which users could learn an application so it caught on quick and became an industry standard. Primary methods used in

4697-497: The other way around; user interfaces were considered overhead, and software was designed to keep the processor at maximum utilization with as little overhead as possible. The input side of the user interfaces for batch machines was mainly punched cards or equivalent media like paper tape . The output side added line printers to these media. With the limited exception of the system operator's console , human beings did not interact with batch machines in real time at all. Submitting

When the CUI does not block out the real world and creates augmented reality , the CUI is augmented and uses an augmented reality interface . When a UI interacts with all human senses, it is called a qualia interface, named after the theory of qualia . CUI may also be classified by how many senses they interact with as either an X-sense virtual reality interface or X-sense augmented reality interface, where X

4851-431: The room. 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. 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

4928-447: The second phase of command-line systems. These cut latency further, because characters could be thrown on the phosphor dots of a screen more quickly than a printer head or carriage can move. They helped quell conservative resistance to interactive programming by cutting ink and paper consumables out of the cost picture, and were to the first TV generation of the late 1950s and 60s even more iconic and comfortable than teleprinters had been to

5005-404: The smallest possible compilers and interpreters. Once the cards were punched, one would drop them in a job queue and wait. Eventually, operators would feed the deck to the computer, perhaps mounting magnetic tapes to supply another dataset or helper software. The job would generate a printout, containing final results or an abort notice with an attached error log. Successful runs might also write

5082-557: The software dedicated to control the physical elements used for human–computer interaction . The engineering of human–machine interfaces is enhanced by considering ergonomics ( human factors ). The corresponding disciplines are human factors engineering (HFE) and usability engineering (UE) which is part of systems engineering . Tools used for incorporating human factors in the interface design are developed based on knowledge of computer science , such as computer graphics , operating systems , programming languages . Nowadays, we use

5159-567: The term "VR", was unable to represent virtual reality, and instead displayed 360-degree interactive panoramas . Nintendo 's Virtual Boy console was released 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. Forte released the VFX1 ,

5236-411: The term "virtual reality" in the popular media is attributed to Jaron Lanier , who in the late 1980s designed some of the first business-grade virtual reality hardware under his firm VPL Research , and the 1992 film Lawnmower Man , which features use of virtual reality systems. One method of realizing virtual reality is through simulation -based virtual reality. For example, driving simulators give

5313-412: The user clicks on the window border (See picture). User interaction works entirely by using the different mouse buttons on window borders and the desktop background. Combinations of mouse clicks can trigger more complex actions such as moving a window from one workspace to another or loading multiple programs (or multiple instances of a single program) at a time. For that reason, efficient usage of UDE

5390-475: 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. 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

5467-616: The user the ability to view three-dimensional images. Mixed reality (MR) is the merging of the real world and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time. A cyberspace is sometimes defined as a networked virtual reality. Simulated reality is a hypothetical virtual reality as truly immersive as the actual reality , enabling an advanced lifelike experience or even virtual eternity. The development of perspective in Renaissance European art and

5544-445: The verdict was in favour of ZeniMax, settled out of court later. In 2013, Valve discovered and freely shared the breakthrough of low-persistence displays which make lag-free and smear-free display of VR content possible. 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

5621-496: Was a series of request-response transactions, with requests expressed as textual commands in a specialized vocabulary. Latency was far lower than for batch systems, dropping from days or hours to seconds. Accordingly, command-line systems allowed the user to change their mind about later stages of the transaction in response to real-time or near-real-time feedback on earlier results. Software could be exploratory and interactive in ways not possible before. But these interfaces still placed

5698-513: 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 . By 2016, there were 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

5775-462: 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. In 2016, HTC shipped its first units of the HTC Vive SteamVR headset.
