Learning Goals
•How does affect play a role in human-computer interaction?
•…in design?
•…in anthropomorphic devices like robots?

Norman Levels of Design
• Visceral
• Behavioral
• Reflective
• Affect and Emotion– Affect is the basic human feeling
behavior
– Emotion involves perception and memory and always includes an environmental factor, present or past

Game design
• Overall sensory look and feel• Music and sound effects• Emotions are the key drivers
– Fear, Sex, Aggression,….
• Haptic/tangible (e.g,. For driving games)

Reflective Level: Message, culture, meaning
• Personal remembrances• Self image• Watches as an example

Visceral vs. Reflective
• Attractiveness is a visceral-level phenomenon– Beauty comes from the reflective level
• Sexy, powerful, seductive – visceral level– Prestige, rarity, exclusiveness –
reflective level
How does this apply to interaction design?

Emotional Machines
• What are emotions?– Emotion as an attribution that
explains behavior– States of readiness– Emotions allow us to translate
intelligence into action
Does your car have emotions?

Human-Robot interaction
• Anthropomorphism and expectations
• The uncanny valley• Displaying the machine’s
emotional state– Facial expressions– Fake vs. real emotions
CS147 - Terry Winograd - 19
Machines Assessing People’s Emotional State
• Facial expression• Physiological signals
– (blood pressure, galvanic skin response, facial expression....)
How and when should machines respond to your affect?
