Eye-tracking is the process of monitoring the motion of the globes, changes in pupil size, or refractive error of the lens. Detailed quantification of the eyes can lead to further understanding of the oculomotor and visual system and indirectly various neural systems. The eyes and their motion can be a conduit to the brain. Due to the somewhat relative ease and multiple methods available for eye-tracking, compared to other measurement techniques, eye-tracking can be a portable and dependable tool for understanding and studying the fundamentals of neural function, plasticity, and degradation.

This collection brings together a wide range of techniques and unique applications for eye-tracking. Techniques may include utilizing consumer-grade cameras such as those available in webcams or phones to ones embedded in virtual reality heads to research-grade high frame rate cameras monitoring the slightest of displacements and changes. Applications in this collection may include visual processing dysfunctions, binocular dysfunctions, visual field related disorders such as glaucoma, traumatic brain injuries including concussions, neurodegenerative disorders such as multiple sclerosis, Alzheimer’s disease, or Parkinson’s disease, and developmental disorders such as autism spectrum disorder.
