Q&A

> How does it work?

Your webcam detects your facial expression using face-api.js that runs entirely in your browser. There are 2 chatrooms: smile for #happy or look sad for #sad.

> Can other people see my face?

No. Your camera feed is never transmitted. All detection happens locally on your device.

> Is my facial data stored?

No. No images or facial data are saved or sent anywhere. The AI model processes frames in real-time and discards them immediately.

> What if my expression changes?

You automatically move to a new chatroom. The system requires you to hold an expression for a few seconds before switching, so you won't flip between rooms accidentally.

> What if no face is detected?

You stay in your current room and can continue chatting. The display will show "NO FACE DETECTED."

> Who made this?
