Basically, these AR headsets have transparent lenses that let you look at your surroundings, instead of completely replacing your vision with a computer-generated image. They can still project images over whatever you're looking at, but those images are designed to complement and interact with the area around you. You can make a web browser pop up in the middle of a room, for instance, or watch animals run around your coffee table. It's fascinating technology that could hint at the future of computing. https://www.aliexpress.com/item/Roofull-360-Degree-Action-Video-Camera-Wifi-Mini-2448-2448-16MP-Ultra-HD-Panorama-Camera-3D/32703486146.html
In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in 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. https://www.youtube.com/watch?v=v55zEjX-lRE&t=1s
Google and Samsung were the biggest names in mobile VR, with Google Cardboard and the Daydream View, and Samsung's line of Gear VR headsets. They respectively worked with Google's and Samsung's flagship phones, like the Pixel 3 and the Galaxy S9. However, both companies have been very quiet over the last year or so about the category, and we've yet to see a Gear VR headset compatible with the Galaxy S10 series. https://www.youtube.com/watch?v=9vgBDiDpLmU&t=1s
Microsoft has been promoting its partnership with multiple headset manufacturers to produce a series of Windows 10-ready "mixed reality" headsets. The distinction between virtual reality and mixed reality is so far dubious, but it indicates an integration of augmented reality (AR) technology using cameras on the helmet. Acer, Dell, HP, Lenovo, and Samsung are some of Microsoft's partners in this mixed reality program.
Oculus has both tethered and standalone headsets from the Go, to the Quest, to the Rift S. HTC has the Steam-friendly Vive and the developer-focused Vive Pro. Sony has the PS 4-focused PlayStation VR (that will apparently work with the PlayStation 5 if and when that system comes out), and Microsoft is supporting its Windows Mixed Reality platform with a variety of headsets from different manufacturers. https://www.youtube.com/watch?v=zt_qt6QuxKY&t=1s
The two images are then stitched together on the computer just after import. The stitched image (looks like the thumbnail for the above video) is called “equirectangular” format and looks like all 360° got compressed into a single 16:9 frame. Viewers and websites such as YouTube and Vimeo can detect this kind of footage in the file metadata and display it in VR form. https://www.youtube.com/channel/UC3VBuU-Ywv1qJGXLk05R-Dg
In 2016, HTC shipped its first units of the HTC Vive SteamVR headset. This marked 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. https://www.youtube.com/watch?v=zm3oZFu3rO4&t=1s
Virtual reality is most commonly used in entertainment applications such as video gaming and 3D cinema. Consumer virtual reality headsets were first released by video game companies in the early-mid 1990s. Beginning in the 2010s, next-generation commercial tethered headsets were released by Oculus (Rift), HTC (Vive) and Sony (PlayStation VR), setting off a new wave of application development. 3D cinema has been used for sporting events, pornography, fine art, music videos and short films. Since 2015, roller coasters and theme parks have incorporated virtual reality to match visual effects with haptic feedback.
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 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 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." https://www.youtube.com/watch?v=Vz5u547Kpi4&t=1s

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 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 a 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. https://www.aliexpress.com/item/Insta360-PRO-8-K-360-VR-Kamera-Video-4-K-100fps-Gerakan-Lambat-Anti-Shake-Kamera/32832297122.html
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
