These videos show an actor (in fact it is Luyuan Lin, the student who built the system) interacting with the emotionally aware handwashing system.
The system starts with the identities for client as shown (Elder with EPA of [1.67,0.01,-1.03] or Lonesome Elder with EPA of [[-0.64, -0.43, -1.81], significantly less "good", powerful and active than "elder"). The system has an identity of "assistant" (EPA [1.51,0.51,0.45]) except for in the last video where it is a "bossy assistant" (EPA [-0.89,0.52,0.53], significantly less good).
The system uses a Kinect camera and Stephen Czarnuch's hand tracker.
