What are the different patterns of Eye Tracking?
Eye tracking patterns refer to the various types of eye movements and gaze behaviors that individuals exhibit when observing or interacting with visual stimuli. These patterns can provide insights into attention, cognition, and visual processing. Here are 6 different patterns of eye tracking.
- Smooth Pursuit
Nystagmus is an involuntary, rhythmic oscillation of the eyes that typically results from a neurological or vestibular disorder.
Unlike other eye tracking patterns, nystagmus is an unintentional, uncontrolled movement rather than a purposeful, functional eye movement.
A person with nystagmus might have difficulty maintaining a stable gaze on a stationary object, causing their eyes to drift and oscillate.
Saccades are rapid, ballistic eye movements that occur when the eyes shift focus from one point to another.
Saccades differ from other eye tracking patterns in their speed and purpose; they are the fastest eye movements and serve to quickly redirect the gaze.
When reading a sentence, our eyes make saccadic movements to jump from one word to another.
Scanning is a pattern of eye movement that involves a series of short, deliberate saccades and fixations to explore a visual scene or search for specific information.
Scanning is a purposeful, organized eye movement pattern aimed at gathering information, unlike other patterns that may serve different functions or be involuntary.
When looking for a friend in a crowd, we scan the faces with a series of quick eye movements and brief fixations.
Smooth pursuit is a slow, continuous eye movement that maintains focus on a moving object, keeping it centered on the fovea, the area of sharpest vision.
Unlike saccades, smooth pursuit is a slow, steady movement designed to track moving objects rather than rapidly shifting the gaze.
When watching a bird fly across the sky, our eyes engage in smooth pursuit to keep the bird in focus.
Vergence is the simultaneous inward or outward rotation of both eyes to maintain single, binocular vision as an object moves closer or farther away.
Vergence differs from other eye tracking patterns in that it involves coordinated eye rotation to maintain depth perception, rather than individual eye movements.
When focusing on a finger moving closer to the nose, our eyes engage in convergence (inward rotation) to maintain a single, focused image.
Fixations are brief moments when the eyes are relatively stable and focused on a specific point or object, allowing the brain to process and interpret the visual information.
Fixations involve the eyes being stationary, while other eye tracking patterns, such as saccades and smooth pursuit, involve eye movement.
When examining a painting, we make fixations on specific details, pausing momentarily to process the visual information before moving on to the next point of interest.
How does Eye Tracking vary by demographic?
Eye tracking can vary by demographic due to factors such as age, cultural background, and cognitive abilities, which can influence gaze patterns, attention, and visual processing.
As individuals age, changes in visual acuity, cognitive processing, and attention can lead to variations in eye tracking patterns. For example, older adults may exhibit longer fixations and slower saccades compared to younger individuals, possibly due to reduced visual acuity or cognitive processing speed.
Different cultural backgrounds can influence how individuals perceive and process visual information, resulting in variations in eye tracking patterns. For instance, people from Western cultures may exhibit more left-to-right scanning patterns due to the influence of reading direction, while individuals from East Asian cultures may demonstrate more holistic scanning patterns.
Individual differences in cognitive abilities, such as attention span, working memory, or information processing speed, can also affect eye tracking patterns. People with higher cognitive abilities may exhibit more efficient gaze patterns, rapidly identifying relevant information, while those with lower cognitive abilities might display more scattered or disorganized eye movements.
Eye-tracking patterns can vary across demographics due to factors like age, cultural background, and cognitive abilities, which can influence how individuals attend to and process visual stimuli.
What type of research is Eye Tracking?
Eye tracking is primarily a quantitative research method that uses specialized equipment to record and analyze eye movements and gaze patterns during engagement with visual stimuli. This method generates numerical data, such as fixation duration and gaze location, to study attention, cognition, and decision-making. While mainly quantitative, eye tracking can be combined with qualitative methods like interviews or think-aloud protocols for a more comprehensive understanding of participants’ thought processes and behavior.
