1, AR technology is a computer in the real image superimposed on the corresponding image technology, the use of the virtual world into the real world and interact with it, to achieve the purpose of "enhanced" reality.
VR technology is on the computer to generate a three-dimensional space, and the use of this space to provide users with visual, auditory, tactile and other sensory virtual, so that the user as if they were there.
2. The difference between AR devices and VR devices is pretty much the difference between computer vision and graphics.
Augmented Reality, is to understand on the real scene, the virtual scene is just a supplement to the real scene, or to facilitate interaction.
3, and whether the real scene is relevant.
VR equipment is often immersive, the typical device is oculus rift.
But now with the development of real-time 3D modeling technology, vision and graphics a lot of technology began to integrate more and more closely, AR and VR, the two are bound to be more and more intersections in the future.
AR, VR, MR: to clarify the three "R":
One, the real world (Reality)
Reality, that is, the real three-dimensional space that we live in the ordinary people, every day to see, hear, smell, contact with this real world.
The reason why the technical control emphasizes ordinary people is because there are views in the academic community that, in addition to the four-dimensional space after the superimposed time, there are actually other multi-dimensional space, which gives rise to the theory of time travel. Of course, at present, the multi-dimensional space said only stay in the academic research level, not reflected in the actual life of our ordinary people.
Two, Augmented Reality (AR)
Augmented Reality, as the name suggests, augments reality. Augmented with what? With parts of the virtual world.
A common application is to use the cell phone camera, scanning the real world of specific physical objects, through the image recognition technology, in the cell phone terminal to present the corresponding pictures, audio and video, 3D models, etc., so as to give the physical object more information, to achieve the role of augmentation.
