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.

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.  자세히 보기

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.  자세히 보기

The zoo through the eyes of children

Tobii Pro Glasses 2 wearable eye tracker was used to study 6-to 12- year old's perception of the Nordhorn Zoo, in Germany. By collecting and analyzing eye tracking data from the children as they explored the outdoor environments, researchers from the University of Applied Sciences in Germany could provide unbiased insights on one of the zoo's most important group of visitors. 자세히 보기
