With the EO signal, researchers can measure various eyelid movements and benefit from an improved gaze signal quality in their eye tracking study. Here are the key benefits of EO signal:

  • Driver’s drowsiness estimation (e.g., PERCLOS, blink rate, eyelid closing/opening duration, and speed)
  • Insights into human psychology, physiology, and cognitive processes
  • Assessment of eyelid movement-related dysfunctions
  • Accurate blink artifact detection for improved pupil diameter and saccades measurements
  • Easier eyelid artefact detection in EEG data, especially where EOG measurements are not available

The reports provide information about the overall performance of the eye openness signal in Tobii Pro Spectrum and Tobii Pro Fusion. It is based on a quality test performed with 100 participants.
