Learning goals
Learning Goals

  • How does affect play a role in human-computer interaction?

  • …in design?

  • …in anthropomorphic devices like robots?


Norman levels of design
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

  • Physical feel – Haptic feedback and tangibility



Game design
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
Reflective Level: Message, culture, meaning

  • Personal remembrances

  • Self image

  • Watches as an example




Visceral vs reflective
Visceral vs. Reflective

  • Attractiveness is a visceral-level phenomenon

    • Beauty comes from the reflective level

  • Sexy, powerful, seductive – visceral level

Emotional machines
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

  • Displaying the machine’s emotional state

    • Facial expressions

    • Fake vs. real emotions


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?

Manipulating Affect and Motivation

  • Captology is the study of computers as persuasive technologies. This includes the design, research, and analysis of interactive computing products created for the purpose of changing people's attitudes or behaviors.
