Play and Learn

Learn ASL with PopSign

Teaching an infant sign language accelerates their language skills, whether they are hearing or deaf.

PopSign is an educational bubble shooter game developed by the Georgia Institute of Technology and RIT/NTID’s Center on Access Technology. The game teaches over 500 American Sign Language (ASL) signs based on the MacArthur-Bates Communicative Development Inventories, which are the first concepts used to teach a language to a child. 95% of deaf infants are born to hearing parents, who often do not know ASL.

PopSign is in beta testing! If you'd like to try it out, download it here for Android from our SignData website. We'd love to hear your comments.

If you notice any bugs, please report them through the in-game form!

Or, you could send us an email at popsigngame@gmail.com

 Worldwide Sign Language Efforts

Our Partners

ISL
Indian Sign Language | BITS Pilani Goa campus

The research team at BITS Pilani Goa campus is interacting with the deaf children, their parents and individuals who regularly interact with them to understand communication gaps encountered. The team is using learning techniques via games to reduce this communication gap. We aim to create a framework to allow mobile app developers to use on-device sign language recognition for educational software for Deaf children, their families, and classmates.

JSL
Japanese Sign Language | The University of Tokyo  

We implemented a sign language learning game on tablets, allowing users to learn sign language anywhere during their free time. Existing Japanese Sign Language (JSL) learning games are limited because they do not recognize sign language, preventing users from practicing effectively, which reduces learning efficacy. To execute this project, we need deep access to the sign language community, know-how for large-scale data collection, and expertise in AI model training. Together, we will capture videos of Deaf signers across Japan, recording targeted concepts without geographic constraints.

Auslan
& SLSL
Australian Sign Language & Sri Lankan Sign Language | The University of Sydney

The SignPlay initiative, developed by researchers at the University of Sydney's AID-LAB, focuses on making Australian Sign Language (Auslan) acquisition more engaging by teaching it through interactive mobile games.
The project's vision is to bridge communication gaps by transforming traditional sign language education into accessible digital play. By leveraging gamification, the initiative aims to empower more people to build and practice their Auslan skills in a natural and fun environment.
