eyetrackingmenetelmät

Eyetrackingmetelmät refers to a range of techniques used to measure and record where a person is looking or the movement of their eyes. These methods are employed across various fields, including psychology, human-computer interaction, marketing, and neuroscience, to understand visual attention and cognitive processes.

The fundamental principle behind most eyetracking methods is to determine the direction of gaze. This is typically achieved by tracking the reflection of infrared light off the cornea and the pupil. Different types of eyetrackers exist, varying in their precision, portability, and application. Remote eyetrackers are mounted on a desk and track gaze from a distance, commonly used for usability studies of websites or software. Head-mounted eyetrackers are worn by the participant and offer greater freedom of movement, suitable for observing behavior in more naturalistic environments.

Data generated by eyetrackingmetelmät includes fixation points (where the eye remains relatively still), saccades (rapid eye movements between fixations), and scanpaths (the sequence of fixations and saccades). These metrics provide insights into what information is being processed, how quickly, and in what order. For instance, in marketing, eyetracking can reveal which product features or advertisements capture consumer attention. In cognitive psychology, it helps researchers understand attentional biases and information processing strategies. The analysis of eyetracking data often involves visualizing gaze patterns on an image or video, or calculating metrics such as dwell time and fixation counts.
