Visual Perception

Eye tracking is an established technique to study the nature of eye movements in how humans perceive, interpret, and operate in their environment.

Perfect for a variety of fields

Eye tracking is an effective tool to study different aspects of visual perception:

  • Understanding eye movements in natural tasks to see how people coordinate actions in real-life tasks revealing cognitive/perceptual processes and/or limitations
  • Looking into change blindness, inattentional blindness, and visual memory
  • Exploring navigation and guidance of visual attention

Making comparison easier

Eye tracking allows researchers to quantify the dynamics of eye movements in visual behavior. This is particularly useful for uncovering patterns and characteristics that are diagnostic of important states or conditions, such as in traumatic brain injury. This objective, quantitative information provides a basis for comparison to normative data, revealing differences that support particular diagnoses or identification of impairments. Examples include:

  • Saccadic performance, such as latency, over/undershoot, and suppression
  • Fixation stability and drift
  • Smooth pursuit, such as alterations of pursuit gain
  • Binocularity and vergence, such as strabismus (uncontrolled inward or outward eye movement) or amblyopia (lazy eye)
  • Nystagmus (rapid, uncontrolled eye movements), such as the slope of the slow phase and amplitude of the fast phase.


Driven by Caravaggio: eye tracking study reveals the artist’s intentions

Researchers at Scienza Nuova in Italy used eye tracking to test the hypothesis that Caravaggio understood how we perceive images and that he, while creating his art, took into account how the environment would affect the viewer’s visual experience.  Read more

Eye tracking used to compare tactile and visual reading strategies

Researchers from the Netherlands used Tobii Pro Glasses 2 and an infrared motion-capturing system in order to understand the reading strategies of both sighted and braille-dependent students when reading algebraic expressions.  Read more

Cardiff University

Cardiff University's School of Optometry and Vision Sciences used eye tracking from Tobii Pro to explore eye movement in people with sight issues. The researchers looked at how environmental factors affected vision deficits. Read more

University of Melbourne

This study conducted at the Department of Optometry & Vision Sciences at the University of Melbourne focused on eye movement disorders, in particular nystagmus, and the possibility of using eye tracking as an established form of diagnosis tool. Read more
