Potential social interaction concepts

[gfodor]

• Add 'facial reactjis' which allow a user to send a directed facial expression which implies a certain social cue (eg, "I noticed you" or "I am thinking the same thing")

• Introduce a hand proxy for body control, where the non-dominant hand becomes a tool the user can use to orient their body or spatial posturing
