Unlocking the Power of Pupillometry with the Gazepoint GP3 Eye Tracker

Pupillometry, the study of pupil size and reactivity, has emerged as a valuable tool in fields ranging from neuroscience and psychology to market research and human-computer interaction. By analyzing changes in pupil diameter, researchers can uncover insights into cognitive load, emotional states, and autonomic nervous system activity. The Gazepoint GP3 eye tracker is uniquely equipped to support such investigations, offering precise, reliable, and cost-effective tools for pupillometry studies.

What is Pupillometry?

Pupillometry focuses on the measurement of pupil size and its dynamic responses to various stimuli. The dilation and constriction of the pupil, controlled by the autonomic nervous system, provide a window into mental processes and physiological states. For example:

  • Cognitive Load: Increased cognitive effort is often associated with larger pupil dilation.
  • Emotional Responses: Pupil size can indicate arousal or engagement levels.
  • Neurological Conditions: Pupillometry aids in diagnosing and monitoring disorders such as traumatic brain injury, glaucoma, and Parkinson’s disease.
