Eye Tracking¶
The instrumented measurement of eye position, eye motion, or point of gaze relative to a declared head, display, or scene frame, using calibration and qualified interpretation.
Core Idea¶
Eye tracking turns signals from an eye into a time series of ocular position, movement, or estimated gaze. Eye-attached sensors, video-based optical systems, and electrooculography acquire different observables; video trackers commonly use pupil center and corneal reflections. A calibration model then maps sensor features into eye rotation or coordinates in a head, display, or world reference frame.

Scope of Application¶
- Vision and reading research. Fixations, saccades, regressions, and task-dependent scan paths test accounts of visual behavior.
- Human–computer interaction. Gaze records support usability studies and can act as an input channel.
- Assistive control. Calibrated gaze can select targets or control interfaces when other motor channels are limited.
- Applied observation. Design, driving, cartography, and other fields use gaze patterns with domain-specific validity controls.
Clarity¶
Reports should name device type, sampling rate, accuracy, precision, calibration, reference frame, event-detection rule, missing-data treatment, and participant task. A heat map without these details can hide whether a pattern comes from actual gaze, head motion, calibration drift, smoothing, or aggregation. Cognitive claims need independent theory or corroboration beyond the coordinate trace.
Manages Complexity¶
Eye tracking compresses high-frequency sensor signals into gaze coordinates and then into events or spatial summaries. Each layer removes detail and introduces assumptions: optical feature extraction, calibration geometry, fixation thresholds, and aggregation across people. Keeping those transformations visible makes a complex trace usable without treating a visualization as raw observation.
Abstract Reasoning¶
- Choose a sensing method appropriate to the required precision, movement freedom, and participant burden.
- Define the head, display, or world reference frame and perform participant-specific calibration.
- Record signals with synchronized task and scene information while monitoring tracking loss and drift.
- Map sensor observations to eye or gaze coordinates and quantify quality.
- Derive fixations, saccades, or scan paths using a stated algorithm and thresholds.
Knowledge Transfer¶
Eye tracking transfers among research, interface, assistive, and applied settings when ocular signals, calibration, coordinates, and quality controls remain intact. A cursor trail or head orientation can be correlated with gaze but is not literal eye tracking. The broader measurement pipeline transfers widely; the physiological target and gaze geometry make this domain-specific.

Neighborhood in Abstraction Space¶
Eye Tracking sits in a crowded region of the domain-specific corpus (33rd percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
