1. Definition:
What is VR?
VR refers to the virtual reality (Virtual Reality, referred to as VR, also translated as spiritual environment, magic really), is a high-tech in recent years, also called Virtual Reality technology or artificial environment. Virtual reality is a three-dimensional space using the virtual world of computer simulation generated, providing the user simulation for visual, auditory, tactile and other sensory, allowing users as immersive general, in time, there is no limit to observe within the three-dimensional thing.
What is AR?
AR refers to the Augmented Reality (Augmented Reality, referred to as AR), also known as mixed reality. It is through computer technology, virtual information to the real world, the real environment and virtual objects in real time superimposed on the same screen or space exist.
The difference 2.VR and AR:
Simply put, virtual reality (VR), to see the scenes and characters are all false, is your sense of substituting a virtual world. Augmented Reality (AR), see scenes and characters are part of the real part is false, is the virtual information into the real world.
(1) the difference between interactive
VR equipment: Because VR is pure virtual scene, so more interactive VR equipment is used for user interaction with the virtual scene, more use is: position tracker, data glove (5DT and the like) , motion capture system, data helmets and the like.
AR Equipment: Because AR is a combination of real-life scenarios and virtual scene, so basically we need a camera, the screen base taken by a camera on the combination of the virtual screen to display and interact with, such as GOOGLE GLASS these (in fact, strictly speaking, IPAD, mobile phones these products only with a camera, can be used for AR, AR just install the software on it.)
(2) technical difference
is similar to game production, to create a virtual environment for people to experience, its core is the technology of graphics play. And we have the most contact is used in the game, it can be said to be an upgraded version of the traditional game entertainment devices, whether focused on virtual scene have a good experience. And is associated with the real scene, they do not care. VR equipment is often submerged, the typical equipment is oculus rift.
AR applications a lot of computer vision technology. AR device to emphasize the function of restoring human vision, such as automatic tracking to identify the object, rather than to point out that I manually; independent tracking and the surrounding real scene 3D modeling, rather than shining I opened the Maya scene to do a very similar. Typical AR device is an ordinary mobile phone terminal, such as an upgraded version of Google Project Tango.
