Self appearance

• The feeling of being present in the virtual world and the ability to judge scale in it are enhanced if the user is able to see her corresponding body in VR.
• A simple virtual body is much better than having none at all.
• Unexpected differences between the virtual body and real body may be alarming. They could have a different gender, body type, or species. This could lead to a powerful experience, or could be an accidental distraction.
• If only head tracking is performed, then the virtual body should satisfy some basic kinematic constraints, rather than decapitating the user in the virtual world (Section 9.4).
• Users' self-appearance will affect their social behavior, as well as the way people around them react to them (Section 10.4).
