Indian Sign Language · for hearing families of Deaf children
A mirror that
teaches your hands
to sign.
दर्पण means mirror. SignDarpan shows you a real Deaf signer, then watches you on your webcam and coaches your handshape, place and movement — so families can start signing correctly, fast, inside the window that matters most.
Real Deaf-signer video · runs in your browser · your camera never leaves your device.
Why this exists
So the bottleneck isn't translation — it's a family learning to sign right, quickly. That's the gap SignDarpan fills.
How it works
- 01
Watch a real signer
Every sign is demonstrated by a real Deaf signer — never an avatar, never invented.
- 02
Mirror it
Your webcam puts you beside the teacher, with a target outline to fit your hand into.
- 03
Get coached
An on-device check compares your handshape, place and movement and gives a plain tip.
Built with care, not hype
- Free & non-commercial. No charge, no ads, no selling data.
- Real Deaf-signer content. Videos from the AI4Bharat INCLUDE dataset (CC BY 4.0).
- Private by design. The webcam runs entirely in your browser; video never leaves your device.
- Honest. A self-check coaching aid — not a replacement for a Deaf teacher or interpreter.

HELLO
VIDEO_BASE_URL in js/config.js.Every camera and every signer is different — teach the AI yours. Tap "Teach the AI your signing" once per sign: 3 quick takes teach it your hands, your camera and your room, so it can recognise you.
- Watch the teacher video first, then sign the same sign, honestly, all 3 times — the takes teach the AI, so a wrong take teaches it wrong.
- Sit like the teacher: waist up in the frame, about an arm-and-a-half away, hands big and clear.
- Sign it the way you naturally would — your size, your speed. The AI is learning your signing, so natural beats perfect.
