Look the other way.

Anti-saccade experiment. When a blue target appears, look to the opposite side. The camera estimates the direction of your gaze.

Exploratory prototype, not a validated oculography instrument. Sessions pause if center fixation drifts; recalibrate before restarting. Gaze estimates from Face Landmarker may not resolve fast saccade timing. Latency and error metrics are marked unavailable if sample coverage is inadequate. Camera frames remain on this device; model assets load from Google CDN. No video is uploaded. Results are saved only when you export them.
