  2. What is relevance to HCI ? - 1 • Our face is an human-human interface • Interfaces are complicated • Interfaces are subtle • Role in HCI for subliminal effects ? • User response can be hard to judge • Face hard to interpret, at times

  3. What is relevance to HCI ? - 2 • Cultural differences pertain to HCI design • Useful HCI design info ? • HCI diffs: Japan v. USA • Humans have special processors • Useful HCI design info ? • Physiological principles pertain to HCI • Human behavior principles pertain to HCI

  4. What is relevance to HCI ? - 3 • Human response is highly variable • Inputs not accepted well in some excited states • Understanding facial communications can lead to better HCIs • Can we use this special processor?

  5. What is relevance to HCI ? - 4 • Nonverbal, nontextual communications can dominate effect • Emotion has a role in interfaces • How ? • Some people have phobia • Be aware of idiosyncratic behavior • 13th floor?

  6. What is relevance to HCI ? - 5 • Face-to-Face is preferred to machine mediated communications • What are design implications ? • Anthropomorphic designs • Evocative? • Context plays significant role in human response
