To stream VR videos on the Oculus Quest 2, you'll need a VR video player app that supports streaming from a remote server. There are several options available on the Oculus Store, but some popular choices include Skybox VR Player, Pigasus VR Media Player, and Moon VR Player.

First, you can use Google Cardboard. It's a more affordable alternative to a VR headset, but still a good one. Another one is to use a VR app on your smartphone, then look for a 360-degree video. You can also use a computer with special software that simulates a VR environment.

PCVR, or PC Virtual Reality, uses a powerful computer to make the VR experience possible. So basically your VR headset is a monitor you put on your head, but it doesn't do any of the rendering of the game.

You move as if you were really in the game. Some VR headsets have sensors you can hang in the room, which accurately follow your movements. With other VR headsets, the sensors are in the headsets. You can also set up a digital play zone before you start.
