What is virtual reality?

Virtual reality is probably the highest known among the three technology types, whether it's Oculus Rift, HTC Vive, or Sony PlayStation VR, which has been on the headlines for a while.

VR devices are basically a head-mounted display that creates a completely virtual space with a built-in display. Its image generation and rendering is taken care of by connected computers, game consoles, or mobile phones, and the addition of motion sensors can project your actions into the virtual world to achieve an immersive feel.

TelePresence is the core of VR. By working with a range of hardware and software, VR devices have the ability to trick your brain and make you think you're really in another world. However, due to the immature technology, the actual effect of VR equipment is not particularly good at present, the user may experience the vertigo due to the delay (turning the movement and the actual angle of view).
