Children with attention-deficit/hyperactivity disorder (ADHD) are highly vulnerable to visual distractions in therapeutic and home environments, often reducing the effectiveness of rehabilitation interventions. Eye-tracking technology offers a novel tool to objectively quantify visual attention and identify distracting stimuli. This study aimed to evaluate the feasibility and test–retest reliability of a desktop-based eye-tracking system in detecting distracting visual elements presented in simulated rehabilitation and home environments for children with ADHD.
Methods:
Sixteen children with ADHD (8–12 years, 10 boys, 6 girls) participated. Each child viewed a high-resolution panoramic image of a therapeutic room and home setting displayed on a monitor for 8 seconds in two repeated trials separated by a 15-minute interval. Eye-tracking metrics included fixation duration on task-relevant versus distracting stimuli, number of distractor fixations, and heat map distributions. Reliability was assessed using Pearson correlation and intraclass correlation coefficients (ICC).
Results:
Mean fixation duration on task-relevant areas was 4.3 seconds (SD = 0.5) in Trial 1 and 4.4 seconds (SD = 0.4) in Trial 2. Distractor fixations averaged 3.0 (SD = 1.2) in Trial 1 and 3.1 (SD = 1.1) in Trial 2. Reliability analyses revealed strong consistency: fixation duration (r = 0.83, ICC = 0.81), distractor fixations (r = 0.85, ICC = 0.84). Heat maps demonstrated nearly identical gaze patterns across trials.
Conclusion:
Eye-tracking technology demonstrated strong feasibility and reliability for detecting distracting visual stimuli in rehabilitation and home-like environments for children with ADHD. These findings support its application as an objective, repeatable tool for assessing environmental distractors in clinical and home-based rehabilitation contexts.
