Study demo

Participation is voluntary. Webcam access is required to capture reaction signals during the study.

We will process raw webcam frames and derived features (for example AU traces, blink dynamics, coarse gaze-on-screen proxy, and quality/confidence metrics). We do not claim direct dopamine measurement or precise eye tracking.

If enabled for this study, post-view chat reflections may be processed by a language model provider to generate follow-up questions.

Raw media and derived features follow study retention/deletion policy. You can stop at any time.

Flow: consent, camera check, passive first viewing, timeline annotation, then survey.
