Notes from an online free-software conference

You always have a full avatar, though you could give yourself some floating hands if you really wanted to. An avatar can look like pretty much anything, but our default is a full human shape.

If you're in desktop mode, it looks like most any game. You move with WASD/controller, and the avatar has animations applied to it. Your legs move when you walk, your arms move when you speak or choose an animation.

If you're in VR with for instance the Oculus Touch controllers, you control your arms.

If you're in VR with full body tracking then you control your entire body.
