How the Eye Tracking System Works
This page explains how your eye video is processed, what each graph means, and how the system converts your movements into measurable data.
1. Record Your Eye Video
Record a short slow‑motion video (ideally 120–240 FPS) of your eyes moving left and right. Trim it to 2–3 seconds for best results.
2. Upload & Preprocessing
The system detects your pupils frame‑by‑frame, stabilizes the video, and extracts the horizontal position of each eye over time.
3. Iris Tracking
Each frame is analyzed to locate the center of your iris. These positions form the basis for all graphs and metrics.
4. Graph Generation
- Iris Position Traces: Left/right movement over time.
- Binocular Mismatch: Difference between left and right eye positions.
- Velocity Curves: Speed and smoothness of eye movements.
- Version & Vergence: How well your eyes move together.
- Fixation Stability: Drift or wobble during still moments.
5. Interpretation
These metrics help quantify symptoms related to concussion, visual fatigue, or oculomotor dysfunction. Repeating the test over time allows you to track recovery objectively.
