įoveated rendering is a new technique to reduce the rendering workload. Oculus cited the limited processing power of Xbox One and PlayStation 4 as the reason why they targeted the PC gaming market with their first devices. The graphics processing unit (GPU) also needs to be powerful enough to render the required amount of frames. According to a Valve engineer, the ideal latency would be 7-15 milliseconds. If the system is too sluggish to react to head movement, then it can cause the user to experience virtual reality sickness, a kind of motion sickness. Virtual reality headsets have significantly higher requirements for latency-the time it takes from a change in input to have a visual effect-than ordinary video games. In June 2019, Valve released their own headset, the Valve Index, without a partnership with HTC.Ĭonstraints Latency requirements ![]() In 2019, Oculus and PlayStation VR dominated the VR headset market. In 2017, Chinese company Tencent announced it was preparing to launch its virtual reality headset that year. Asian hardware manufacturers like Xion and Kolke have developed inexpensive virtual reality headsets. Samsung Electronics partnered with Oculus VR to co-develop the Samsung Gear VR (which is only compatible with recent Samsung Galaxy devices), while LG Electronics developed a headset with dedicated displays for its LG G5 smartphone known as LG 360 VR. 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 (and a smartphone with a gyroscope), such as cardboard (hence the naming). VR content is viewed from the screen of the device itself through lenses acting as a stereoscope, rather than using dedicated internal displays. Unlike headsets with integrated displays, these units are essentially enclosures which a smartphone can be inserted into. Virtual reality headsets and viewers have also been designed for smartphones. The Vive was released in April 2016 and PlayStation VR in October 2016. In 2014, Valve demonstrated some headset prototypes, which led to a partnership with HTC to produce the Vive, which focuses on "room scale" VR environments that users can naturally navigate within and interact with. In March 2014, Sony demonstrated a prototype headset for PlayStation 4, which was later named PlayStation VR. The final consumer-oriented release of Oculus Rift began shipping on 28 March 2016. In March 2014, the project's parent company Oculus VR was acquired by Facebook for $2 billion. In 2012, a crowdfunding campaign began for a VR headset known as Oculus Rift the project was led by several prominent video game developers, including Carmack who later became the company's CTO. However, these early headsets failed commercially due to their limited technology, and they were described by John Carmack as like "looking through toilet paper tubes". These VR headsets gave MechWarrior 2 players a new visual perspective of seeing the battlefield from inside the cockpit of their craft. Sony, another pioneer, released the Glasstron in 1997, which has an optional positional sensor, allowing the wearer to view the surroundings, with the perspective moving as the user's head moves, giving a deep sense of immersion. The VFX-1 has stereoscopic displays, 3-axis head-tracking, and stereo headphones. Another early VR headset, the Forte VFX1, was announced at CES in 1994. The Sega VR, announced in 1991 and seen in early 1993 at the Winter CES, was never released for consoles, but was utilized for the Sega VR-1 motion simulator arcade attraction in 1994. History The PSVR headset for the PlayStation 4 video game console, released in 2016 ![]() Still, it does offer an immersive experience. ![]() The technology may not be perfect, as there is latency if the head moves too fast. The VR glasses use a technology called head-tracking, which changes the field of vision as a person turns their head. Some VR headsets also have eye-tracking sensors and gaming controllers. 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. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. Head-mounted device that provides virtual reality for the wearerĪn Oculus Rift CV1 VR headset, that must be wired to a PC and uses external trackingĪ virtual reality headset (or VR headset) is a head-mounted device that provides virtual reality for the wearer.
