It really is that simple. You do need the companion app on your phone first, which will make you log in. You'll also have to grant location access and pair the Go to your Wi-Fi. Once you've done that, and inserted and paired your controller, you're all good to go. There will be a little video that tells you a bit about safety, but that's it. That's how simple it is to set up.
Currently standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates auditory and video feedback, but may also allow other types of sensory and force feedback through haptic technology. https://www.youtube.com/watch?v=3V15IB3pc94&t=1s
