Virtual Reality
Virtual Reality (VR) refers to the technology that creates and places human into an artificial world that is similar but different from the real world.[1]
As a popular technology in the 21st century, virtual reality plays an important role in a wide variety of fields, including entertainment (VR games), social connections (remote meetings) and business(virtual offices). VR related technology includes augmented reality and mixed reality.[2]
Virtual Reality Technology can be classified into three general category based on the extent of human immersion: non-immersive VR, semi-immersive VR, and fully-immersive VR simulations. The non-immersive VR includes most 3D movie and games that portray a virtual world but the user does not enter the virtual world himself or herself. The semi-immersive VR indicates VR technology which provides an immersive virtual world for the user but the user is still somewhat exposed to the real world. The fully-immersive VR simulations refers to the VR technology that enables user to fully immerse in the artificial reality without direct visual contact to the real world.[3]

Definition and Etymology
The word 'virtual' can indicate a material created by computer technology and appearing to exist but not existing in the physical world.[4] The word 'reality' describe the state of things as they actually are. [5] Combining the meaning of the two words, 'virtual reality' refers to a set of images and sounds, produced by a computer, that seem to represent a place or a situation that a person can take part in.[6]
As a relative new terminology, the word 'virtual reality' is first used by Jaron Zepel Lanier, the founder of VPL Research, to refer the first business-grade hardware, which is invented by Jaron himself, that features the use of virtual reality systems.[7]
