Brunswikian Lens Model

1
Brunswikian Lens Model

• A framework for the study of emotional
  communication

2
The Lens Model

• is used in several fields to study how observers
  correctly and incorrectly use objective cues to
  perceive physical or social reality

• cues have a probabilistic (uncertain) relation to
  the actual objects
• a (same) cue can signal several objects in the
  environment
• cues are (often) redundant

Lens model research

• Developed for the study of visual perception
  Brunswik (1956)
• Immediately applied to judgment analysis
  (decision making, medical diagnosis, weather
  forecast) Hammond (1955)
• Rapidly oriented towards interpersonal perception
• Interpersonal dispositions (dominant,
  extraverted, agreeable ) Gifford (1994)
• Intelligence Reynolds Gifford (2001)
• Rapport Bernieri Gillis (2001)
• Emotions (but only in music) Juslin (1998)

  lens
• Scherer (1978)

Implications for HMI

• If matching is low

Important for ECAs
Important for Automatic Recog..

• ECA developers should focus on the relation of
  the cues to the perceived emotion

• Automatic recognition system developers should
  focus on the relation of the cues to expressed
  emotion

( Mind individual differences) ( Mind
broad/abstract categories)
