VR(Virtual Reality), also called virtual reality, simulates a virtual environment close to reality to users through information technology. Players need to wear special VR eyes and cool 3D experience to immerse players in the virtual world. AR(Augmented Reality), also known as augmented reality, is usually realized by head-mounted devices, the most famous of which is Google Glass, but some basic AR functions can also be realized by mobile terminals (such as Google's Project Tango) or even ordinary mobile phones. AR technology allows users to receive digital information and data related to the real world while observing the real world, thus helping users' work and behavior. Moreover, HTC vive, Oculus Rift and PS vr are all better vr glasses brands on the market. The first two are PC-side devices, and the latter is an all-in-one machine. There are also vr virtual reality devices such as gear vr, Storm Mirror, Da Peng, Ant Vision VR and Xiaomi Box. At present, htcvive has a good experience, followed by Oculus and psvr. A better mobile phone is gear vr, that's all. You can buy it for a few hundred dollars. If it is better, it must be thousands. If you want something good and don't care about the price, I suggest tens of thousands! You must have his reasons.
