But her right hand is moving, and her avatar's left hand is moving

You have to image controlling it yourself.  When you are standing in front of that image and the menu item is to the right of your body, you will move your right hand to activate it.  The avatar on screen will be moving the left hand.  Just like looking at a mirror.
