Your avatar represents you in the VR world. With your avatar you can walk around and interact with the world.
Use your keyboard to walk. You can use W,A,S,D or the arrow keys to walk forward, backward, left, and right.
You can control the direction that you look. To turn your field of view, "left-click" and drag your mouse across the screen in any direction.
It is strongly recommended that all desktop users use a mouse for dexterity and control.
