Virtual Reality Headsets
A virtual reality headset (or VR 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 (providing separate images for each eye), 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. Some VR headsets also have eye-tracking sensors and gaming controllers. The VR glasses use a technology called head-tracking, which changes the field of vision as a person turns their head. The technology may not be perfect, as there is latency if the head moves too fast. Still, it does offer an immersive experience. History The Sega VR, announced in 1991 and seen in early 1993 at the Winter CES, was never released for consoles, but was utilized for ...

ArsTechnica
''Ars Technica'' is a website covering news and opinions in technology, science, politics, and society, created by Ken Fisher and Jon Stokes in 1998. It publishes news, reviews, and guides on issues such as computer hardware and software, science, technology policy, and video games. ''Ars Technica'' was privately owned until May 2008, when it was sold to Condé Nast Digital, the online division of Condé Nast Publications.

VirtualLink
VirtualLink was a proposed USB-C alternate mode that was historically intended to allow the power, video, and data required to power virtual reality headsets to be delivered over a single USB-C cable and connector instead of set of three different cables as it was in older headsets. The standard was supported by Nvidia, AMD, HTC Vive, Oculus VR, Valve, and Microsoft. The VirtualLink Consortium was chaired by Rambo Jacoby representing Nvidia. VirtualLink never launched successfully. VirtualLink specifications According to its specifications, the VirtualLink cable consisted of: * DisplayPort: ** 4x DisplayPort balanced pair data path ** DisplayPort HPD (hot-plug detection pin) as a single wire. ** DisplayPort AUX signal as a balanced pair * USB 3.1 signals ** A USB TX balanced pair for USB 3.0 data ** A USB RX balanced pair for USB 3.0 data * I2C wire to control the USB Billboard interface, in case the cable is plugged into an unsupported interface. * VBUS carrying power to HMD v ...

Reality Labs
Reality Labs is a business of Meta Platforms (formerly Facebook Inc.) 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. Reality Labs is the corporate successor to Oculus, a company that was founded in 2012 by Palmer Luckey, Brendan Iribe, Michael Antonov and Nate Mitchell to develop a VR headset for video gaming known as the Oculus Rift. Before the acquisition, Oculus raised over $2.4 million for the project via a crowdfunding campaign on Kickstarter—nearly ten times the original goal of $250,000. Oculus was acquired by Facebook in March 2014. The company partnered with Samsung Electronics to release the Gear VR accessory for Samsung Galaxy smartphones in 2015. In March 2016, Oculus released the first consumer version of the Rift headset. In 2017, the company released a standalone mobile headset known as Oculus Go, produced by Xiaomi. In 2019, i ...

VG247
''VG247'' is a video game blog published in the United Kingdom, founded in February 2008 by industry veteran Patrick Garratt. In 2009, CNET ranked it as the third best gaming blog in the world. History Founded in collaboration on 1 February 2008 between games journalist Patrick Garratt and Eurogamer Network, ''VG247'' was set up to be a news-only blog, the first of its kind in the UK to have a specialist games blog found among the likes of American sites ''Kotaku'' and ''Joystiq''. At launch, ''VG247'' did not review video games and focused instead on news, interviews, and previews. Garratt was the only staff member at the time of launch, although grew in time with the addition of contributors Mike Bowden and Nathan Grayson. In early 2009, the site relaunched itself, rebranding from ''videogaming247.com'' to ''VG247''; at the same time the site changed its primary url to ''www.vg247.com'', and launched a new site design, with improved features, and staff. The site added additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

Accelerometer
An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards (by definition) of g ≈ 9.81 m/s2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero. Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise flight. ...

Touchpad
A touchpad or trackpad is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is made output to the screen. Touchpads are a common feature of laptop computers as opposed to using a mouse on a desktop, and are also used as a substitute for a mouse where desk space is scarce. Because they vary in size, they can also be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available as detached accessories. Operation and function Touchpads operate in one of several ways, including capacitive sensing or resistive touchscreen. The most common technology used in the 2010s senses the change of capacitance where a finger touches the pad. Capacitance-based touchpads will not sense the tip of a pencil or other similar ungrounded or non-conducting implements. Fingers insulated by a glove may also be problemat ...

Joystick
A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It often has supplementary switches to control various aspects of the aircraft's flight. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. Aviation Joystic ...
