What is VR
For a start lets look in to the “VIRTUAL” original meaning:
“Being something in effect, though not in actually or in fact”, this is from the 15th century, Douglas Harper Etymology Dictionary.
So, in plain 2020 language: Virtual Reality (VR) is approximation of our reality, that is digital but no real itself. VR encompasses all virtually immersive experiences. These could be created using purely real-world content (360 Video), purely synthetic content (Computer Generated), or a hybrid of both.
To make is easier, on one end you have WebVR, the simplest and most accessible form, and on the other you have Fully-Immersive VR, like Multi-sensory Cinema.
What is VR
Augmented Reality (AR) also know by some as mixed reality is totally different concept from VR. Its main purpose isn’t to cut out the real world and transport you to another one, but rather is to be enhancement of the world with magical objects in it. When a person real environment is supplemented or augmented with computer generated images, in a lot of cases motion tracked, then that is AR.
Fun fact, “Augmented” comes from the Latin word “Augere”, meaning “to increase” or “to add”.
In plain language, AR is an overlay of computer-generated (GC) content on the real world. AR doesn't recognize the physical objects within a real-world environment, so the CG content and the real-world content are not able to respond to one another.
What is VR
Mixed Reality (MR) removes the boundaries between real and virtual interaction via blending. Blending in this case means the computer-generated objects can be visibly obscured by objects in the physical environment—like a virtual robot disassembling the engine of your car.
In other words, in mixed reality, you interact with and manipulate both physical and virtual items and environments, using next-generation sensing and imaging technologies.
