Area of Science:

  • Vision science
  • Neuroscience
  • Experimental psychology

Background:

  • Dichoptic presentation is crucial for 3D vision and interocular suppression research.
  • Pupillary and oculomotor measures offer unique insights into interocular suppression.
  • Existing methods for combining dichoptic presentation and eye tracking are often limited by hardware interference.

Purpose of the Study:

  • To describe and guide the construction of an experimental setup integrating dichoptic presentation with infrared eye tracking.
  • To provide an affordable and accessible solution for researchers studying 3D vision and interocular suppression.
  • To overcome hardware limitations that compromise eye-tracking quality in dichoptic studies.

Main Methods:

  • Utilized infrared-transparent mirrors to combine a standard dichoptic presentation system with a video-based infrared eye tracker.
  • Ensured compatibility with standard monitors and eye trackers.
  • Focused on a cost-effective implementation (approx. US$1,000).

Main Results:

  • The described setup allows for high-quality eye tracking during dichoptic presentation.
  • The system is compatible with standard equipment and does not require specialized hardware.
  • It imposes minimal limitations on the nature and quality of visual stimuli.

Conclusions:

  • The developed setup offers a practical and affordable solution for integrating dichoptic presentation and eye tracking.
  • This facilitates advanced research in 3D vision and interocular suppression by enabling precise oculomotor measurements.
  • The method is easy to implement and broadly applicable to vision research.
