What is AR /VR /MR /XR

   Nowadays, With widespread technology, several concepts start to show. And augmented reality (AR), as well as virtual reality (VR), mixed reality (MR) and extended reality (XR), are not exceptions. So, what do these concepts mean?!

Augmented Reality (AR)

Augmented Reality is a live, direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. AR allows the user to interact with both the real world and digital elements or augmentations. it is the overlaying of digitally-created content on top of the real world.

As Augmented Reality exists on top of our own world it provides as much freedom as you are given within your normal life. AR utilizes your existing reality and adds to it utilizing a device of some sort. Mobile and tablets are the most popular mediums of AR now, through the camera, the apps put an overlay of digital content into the environment. Custom headsets are also being used. As popular AR examples, there are Pokemon Go and Snapchat’s new AR emojis.

Augmented Virtuality  (VR)

in short, it refers to bringing real-world objects into virtual worlds where they can be interacted with. It could be seen as a reversal of – or mirror to – what augmented reality is.

Virtual Reality is an immersive experience also called a computer-simulated reality. It refers to computer technologies using reality headsets to generate realistic sounds, images and other sensations that replicate a real environment or create an imaginary world. VR is a way to immerse users in an entirely virtual world. A true VR environment will engage all five senses (taste, sight, smell, touch, sound), but it is important to say that this is not always possible.

Mixed Reality (MR)

This is where things get interesting because removes the boundaries between real and virtual interaction via occlusion. that means the computer-generated objects can be visibly obscured by objects in the physical environment—like a virtual robot scurrying under your coffee table.

Mixed Reality shortly is the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time. It means placing new imagery within a real space in such a way that the new imagery is able to interact, to an extent, with what is real in the physical world we know. The key characteristic of MR is that the synthetic content and the real-world content are able to react to each other in real time.

Extended Reality (XR)

Extended Reality refers to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. Extended Reality includes all its descriptive forms like the Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR). In other words, XR can be defined as an umbrella, which brings all three Reality (AR, VR, MR) together under one term.

XR covers the hardware, software, methods, and experience that make virtual reality, mixed reality, augmented reality, cinematic reality and others a reality. Most definitions of XR encompass platforms and content where the user can take digital objects into reality, or, conversely, see physical objects as present in a digital scene.
