Responsible use

Please read

This is an experimental indicator, not a diagnosis. Lighting, camera angle, glasses, face movement and individual differences can cause missed detections or false alerts. A closed-eye cue alone cannot determine whether someone is asleep. Do not use this prototype to decide whether it is safe to drive or operate equipment. If you feel sleepy, stop what you are doing when safe and rest. Camera access generally requires HTTPS or localhost[cite: 2].
