PUPIL DIAMETER

A correlation between the diameter of the pupil and the mental workload of the brain has been found as early as in the 70s.

With the simple detection of the pupil size in modern eye tracking systems it is now possible and practical to study this measurement systematically.

  • Significance for the emotional intensity: high
  • Informative value on the kind of emotion: low
  • Informative value on the mental workload: high
  • Effort: measurements through standard eye tracking systems
