Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment, education and business. Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry.
A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. They may also control output to the display if the display driver is part of the graphics hardware. Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware.
Tegra is a system on a chip (SoC) series developed by Nvidia for mobile devices such as smartphones, personal digital assistants, and mobile Internet devices. The Tegra integrates an ARM architecture central processing unit (CPU), graphics processing unit (GPU), northbridge, southbridge, and memory controller onto one package. Early Tegra SoCs are designed as efficient multimedia processors. The Tegra-line evolved to emphasize performance for gaming and machine learning applications without sacrificing power efficiency, before taking a drastic shift in direction towards platforms that provide vehicular automation with the applied "Nvidia Drive" brand name on reference boards and its semiconductors; and with the "Nvidia Jetson" brand name for boards adequate for AI applications within e.g. robots or drones, and for various smart high level automation purposes.
Oculus Rift is a discontinued line of virtual reality headsets developed and manufactured by Oculus VR, a virtual reality company founded by Palmer Luckey that is widely credited with reviving the virtual reality industry. It was the first virtual reality headset to provide a realistic experience at an accessible price, utilizing novel technology to increase quality and reduce cost by orders of magnitude compared to earlier systems. The first headset in the line was the Oculus Rift DK1, released on March 28, 2013. The last was the Oculus Rift S, discontinued in April 2021.
Tango was an augmented reality computing platform, developed and authored by the Advanced Technology and Projects (ATAP), a skunkworks division of Google. It used computer vision to enable mobile devices, such as smartphones and tablets, to detect their position relative to the world around them without using GPS or other external signals. This allowed application developers to create user experiences that include indoor navigation, 3D mapping, physical space measurement, environmental recognition, augmented reality, and windows into a virtual world.
Reality Labs is a business and research unit of Meta Platforms that produces virtual reality (VR) and augmented reality (AR) hardware and software, including virtual reality headsets such as Quest, and online platforms such as Horizon Worlds. In June 2022, several artificial intelligence (AI) initiatives that were previously a part of Meta AI were transitioned to Reality Labs. This also includes Meta's fundamental AI Research laboratory FAIR which is now part of the Reality Labs - Research (RLR) division.
The PlayStation VR is a virtual reality headset developed by Sony Interactive Entertainment, which was released in October 2016.
Google Cardboard is a discontinued virtual reality (VR) platform developed by Google. Named for its fold-out cardboard viewer into which a smartphone is inserted, the platform was intended as a low-cost system to encourage interest and development in VR applications. Users can either build their own viewer from simple, low-cost components using specifications published by Google, or purchase a pre-manufactured one. To use the platform, users run Cardboard-compatible mobile apps on their phone, place it into the back of the viewer, and view content through the lenses.
The Samsung Gear VR is a virtual reality headset developed by Samsung Electronics, in collaboration with Oculus VR, and manufactured by Samsung. The headset was released on August 21, 2015.
Windows Mixed Reality (WMR) is a discontinued platform by Microsoft which provides augmented reality and virtual reality experiences with compatible head-mounted displays.
HTC Vive is a line of virtual and mixed reality headsets produced by HTC Corporation. The brand currently encompasses headsets designed for use with personal computers as well as standalone headsets such as the Vive Focus line, Vive Flow glasses, and the Vive Elite XR mixed reality headset.
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 developed by Razer and Sensics.
Oculus Touch is a line of motion controller systems used by Meta Platforms virtual reality headsets. The controller was first introduced in 2016 as a standalone accessory for the Oculus Rift CV1, and began to be bundled with the headset and all future Oculus products beginning in July 2017. Since their original release, Touch controllers have undergone revisions for later generations of Oculus/Meta hardware, including a switch to inside-out tracking, and other design changes.
A virtual reality headset is a head-mounted device that provides virtual reality for the wearer. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display, stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world.
Daydream is a discontinued virtual reality (VR) platform which was developed by Google, primarily for use with a headset into which a smartphone is inserted. It is available for select phones running the Android mobile operating system that meet the platform's software and hardware requirements. Daydream was announced at the Google I/O developer conference in May 2016, and the first headset, the Daydream View, was released on November 10, 2016. To use the platform, users place their phone into the back of a headset, run Daydream-compatible mobile apps, and view content through the viewer's lenses.
Foveated rendering is a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision.
A virtual reality game or VR games is a video game played on virtual reality (VR) hardware. Most VR games are based on player immersion, typically through head-mounted display unit or headset with stereoscopic displays and one or more controllers.
The Oculus Go is a standalone virtual reality headset developed by Meta Reality Labs in partnership with Qualcomm and Xiaomi. It is in the first generation of Facebook Technologies' virtual reality headsets, and the company's first device in the category of standalone VR headsets, which was a new category at the time of the Go's release. The Oculus Go was unveiled on October 11, 2017 during the Oculus Connect developer conference, and released on May 1, 2018. Xiaomi launched their own version of the headset in China as the Mi VR Standalone on May 31, 2018.
The first-generation Oculus Quest is a discontinued virtual reality headset developed by Oculus, a brand of Facebook Inc., and released on May 21, 2019. Similar to its predecessor, Oculus Go, it is a standalone device, that can run games and software wirelessly under an Android-based operating system. It supports positional tracking with six degrees of freedom, using internal sensors and an array of cameras in the front of the headset rather than external sensors. The cameras are also used as part of the safety feature "Passthrough", which shows a view from the cameras when the user exits their designated boundary area. A later software update added "Oculus Link", a feature that allows the Quest to be connected to a computer via USB, enabling use with Oculus Rift-compatible software and games.
