The nod is one of the most important signals a person can send. When made at the right time, it means “I am engaged in what you are saying” or “I understand”. For computer programs and robots that are designed to interact with people, being able to notice nods and respond with nods of their own (through an on-screen avatar in the case of a computer, and with actual nods in the case of robots) would be a boon. Unfortunately, nobody has yet been able to get it right.
