Here, we're putting on the latest prototype of Sony's PlayStation VR headset.
It uses magnifying lenses to stretch a smartphone-sized screen across your field of view, letting you see a virtual world.
Putting on the headset is easy: you just pull back on the rear portion of the band, then pull it over your head like a baseball cap.
Then, you twist the clicky dial around back to cinch it up. Just like a bike helmet.
There's a button underneath the front of the headset, too. Push it, and you can slide the optics toward your face or away from it to accomodate glasses or take a breather.
The PlayStation VR headset has a host of bright glowing blue LEDs which get tracked by the PlayStation Camera to help determine which way you're facing in the virtual world.
You can look up, down, left, right, over your shoulder and anywhere to see a corresponding view of the virtual world.
LEDs around back keep your head visible to the system even if you turn all the way around.

Some games use controllers, but other ones simply rely on where you're looking at any given moment.
The PlayStation VR headset doesn't yet have any built-in headphones, so we had to plug in external ones for the demo.
