Proctoring engine · demonstration
A browser-side exam proctor you can actually watch work.
A frontend-only exam-proctoring engine that runs entirely in your browser. Take a short dummy quiz while a real computer-vision loop watches your webcam and flags exam violations live — multiple faces in frame, looking away, downward gaze, poor lighting, a blocked camera, and more. Each flag feeds a weighted risk score with a TTL-debounced warning system. No uploads, no server, no recording — everything runs on-device.
Real webcam, on-device
Your camera feed never leaves the browser. No upload, no server, no recording stored.
MediaPipe detection loop
A real FaceLandmarker model runs ~once a second; pixel math runs in a Web Worker.
Weighted risk scoring
Flags feed a capped, time-decaying 0–100 score — the same model the production engine uses.
TTL de-bounce in localStorage
Each violation type is rate-limited by a stored timestamp, so warnings don't spam.
