The very first time I heard about VR technology was from online novel. Actually it's just a hat worked  like  VR  glasses once a player wear the hat his/her mind will come into the virtual world of online game.

I really heard about the word VR was just a few years ago I heard that SONY company tried to develop PS4.5 whose core is same as PS4 but has a new function which is VR. It uses VR glasses to replace game monitor so that player can feel like they are truly in this game not on
