Contribute your signs
Help SignDarpan grow — one recording at a time.
What this is
SignDarpan teaches Indian Sign Language with videos of real Deaf signers. Right now it covers 262 signs. Your recordings help in two ways:
- Growing the free ISL dataset — more examples of each sign, from more people, make the coaching fairer and more accurate for everyone.
- Future expert references — recordings from Deaf signers and ISL teachers can become new reference material the app checks learners against.
Your privacy
Everything you record is stored privately. Nothing is published. The project owner reviews every contribution before it can be used for anything, and only what you consented to is ever used. By default we save only keypoints — stick-figure coordinates of your hands and body, not a picture of you. Real video is saved only if you switch it on yourself.
Consent
Please read each line.
Only used if you want to be thanked by name on the site one day. Never required.
