Once you're inside a VR Space, you'll see the immersive 360º imagery and a set of blue circles.
Look left, right, up, down, and even behind you to explore the space.
You'll see a grey circle in the middle of your screen. The circle will grow or shrink to demonstrate depth.
Move to a new spot by lining up the grey circle on top of a blue circle and then waiting a few seconds.
Return to the home screen by looking at the ground.
