Physical Emotion Induction

  • Ears: music
  • Eyes: images, montage
  • Mind: storyline
  • Body?

CONCEPT

■■□□□□□□□□□□□□□□

slide3

Physical Emotion Induction

CONCEPT

  • Vibrating game controllers
  • Moving theatre seats
  • Mimicking other input
  • Targeting specific emotions

■■■□□□□□□□□□□□□□

slide4

Physical Emotion Induction

EMOTION

  • William James
    • “Emotion is a result of bodily changes”
  • Central network model(Philippot et al., 2002)
    • Emotions & bodily changes
    • Peripheral feedback
    • Implicit process

■■■■□□□□□□□□□□□□

slide5

Physical Emotion Induction

MODALITIES

  • Facial expression
    • Emotion-specific
  • Posture
    • Relaxed vs. tense
  • Respiration
    • Emotion-specific patterns
  • Temperature
    • Negative affect
  • Pulse
    • Arousal
  • Sweaty palms
    • GSR
  • Scent
    • Emotional memory

■■■■■□□□□□□□□□□□

Physical Emotion Induction

MODEL

  • Difficult to map to specific emotions
  • Pleasure-Activation model(Russel, 2003)

Physical Emotion Induction

EFFECT OF MODALITIES

  • Facial expression
    • Hard to manipulate
  • Posture
    • Influences arousal
  • Respiration
    • Unclear P-A seperation
  • Temperature
    • Influences pleasure
  • Pulse
    • Influences arousal
  • Sweaty palms
    • Relates to arousal
  • Scent
    • Too personal

■■■■■■■■□□□□□□□□

slide9

Physical Emotion Induction

IMPLEMENTATION

  • Chair
  • Three modalities:
    • Posture
    • Pulse
    • Temperature
  • Arduino I/O board,Processing, Max MSP

IMPLEMENTATION

■■■■■■■■■■□□□□□□

slide11

Physical Emotion Induction

EXPERIMENT

“An emotionally charged multimodal experience will be subjectively experienced as being more intense when the physical states related to those emotions are induced than when this is not the case.”

■■■■■■■■■■■□□□□□

slide12

Physical Emotion Induction

EXPERIMENT

  • 20 participants
  • 8 video fragments
  • With / without influence
  • Questionnaire

■■■■■■■■■■■■□□□□

slide13

Physical Emotion Induction

RESULTS

  • No significant effect on emotional intensity
  • Various issues
    • Subtlety
    • Video quality
    • Questionnaire
  • But: selected model seems applicable!
