Microsoft HoloLens is shaping up to be another formidable competitor in the HMD market. Unlike VR tech, Microsoft based their display on holographic technology. The original Hololens was more proof of concept than consumer device, and the recently announced Hololens 2 is again eschewing the public in favor of enterprise/government uses. The Hololens 2 will feature upgraded visuals, including a much-expanded field of view — music to fans of the original device, who settled on the limited FOV as the main drawback of the device.
Virtual reality (VR) is an experience taking place within simulated and immersive environments that can be similar to or completely different from the real world. Applications of virtual reality can include entertainment (i.e. gaming) and educational purposes (i.e. medical or military training). Other, distinct types of VR style technology include augmented reality and mixed reality. https://www.youtube.com/watch?v=ouqtjetglwI&t=1s
Virtual reality, or VR, is a technology that lets you figuratively step inside a computer-generated 3D world. You can explore and sometimes even manipulate objects in that world. Imagine virtually stepping inside a video game, where the game world feels as real as the non-game world. In fact, video games are one of the most exciting and engaging ways to enjoy VR today. https://www.youtube.com/watch?v=BpPcm3qze5I&t=1s

According to CEO Stanislas Chesnais, the 3DRudder was designed for "existing games where two hands aren't enough [for] VR, where you don't actually have any solutions today to move in a nice way while sitting." A circular device that you control with both feet by tilting in the direction you want to move, the 3DRudder's latency-free design means that response to your movements is instant and requires little thought. "It's like in real life," says Chesnais. "When you do something [like] set the table… you don't think about your feet moving around. Your hands are what matter." https://www.youtube.com/watch?v=HNOT_feL27Y&t=1s
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 a 90-degree field of vision that was previously unseen in the consumer market at the time. Distortion issues arising from the lens used to create the field of vision were corrected for by software written by John Carmack for a version of Doom 3. 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 the E3 gaming trade show by Carmack. In 2014, Facebook 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; the verdict was in favour of Zenimax, settled out of court later. https://www.youtube.com/watch?v=MB-ROjqPiUM&t=1s
As of the end of 2018, the three best selling Virtual Reality headsets were Sony’s PlayStation VR (PSVR), Facebook’s Oculus Rift and the HTC Vive. This was not a surprise, seeing as the same three HMDs had also been best sellers in 2017. 2019 sees the VR landscape broadening with Google, HP, Lenovo, and others looking to grab a piece of the still-burgeoning market.
While they can offer a taste of VR, mobile headsets don't provide the full experience. They tend to offer three-degrees-of-freedom (3DOF) motion tracking, following your direction but not your position. They also only come with one motion controller, which is also 3DOF-only. You don't get the same immersiveness you do with six-degrees-of-freedom (6DOF) motion tracking and dual motion controllers, which might be why Google and Samsung have been largely quiet lately about their mobile headsets. The Nintendo Labo VR Kit is its own unique case, but it's more of a novelty for Switch owners. https://www.youtube.com/channel/UC6IVy__hc9NgrBYqpgfIQeg
It's also got a bunch of doodads to help you customise your mobile experience. Adjust the lenses all you want, click two buttons to interact with your content; pop out the front window in case you ever need to use it for mixed/augmented reality purposes. Speaking of which, Merge now also sells the AR Merge cube, which lets you put mixed reality experiences in the palm of your hand. https://www.youtube.com/watch?v=L0bzBxxDQzs&t=1s
