시각적 정보 인지

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

다양한 시각 정보 연구

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

쉬운 비교 분석

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.
