Attention 👀 Gaze Tracker

A webcam eye-tracking version of the Trail Making Test. Click numbered circles in order while your webcam estimates where you're looking. Then see how distractions changed your gaze.

Calibrate: click 9 dots while looking right at them.
Round 1, Baseline: connect 1 to 12, nothing else on screen.
Round 2, Bottom-up: bright shapes flash and zip around. Ignore them!
Round 3, Spatial: targets spread across the whole screen.
Results: gaze heatmaps, completion time and gaze entropy.

Webcam eye tracking is approximate (often 100–200 px off) and works best with even lighting, your face centered, and your head still. Calibration may take a couple of tries. Video never leaves your browser.

Calibration

Look straight at each red dot and click it 5 times until it turns green. Keep your head still.

Click 1 → 2 → 3 … → 12 as fast as you can. Wrong clicks count as errors.

Here's where your attention went

How to read this. Spatial entropy measures how spread out your gaze was across an 8×8 grid (0 = one spot, 1 = evenly everywhere). Transition entropy measures how unpredictable your next glance was, given where you were looking. One run per round is noisy, and webcam tracking is approximate, so treat this as a demo, not a diagnosis. Rounds always run in the same order, so practice may make later rounds faster.
