PopSign

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 sign.
Without access to naturally occurring language acquisition during their critical language-learning years, these children are at risk for Language Deprivation Syndrome (LDS) which can have serious impact on different aspects of these children's lives, such as relationships, education, and employment. 
PopSign is a smartphone game that makes learning American Sign Language fun, interactive, and accessible for anyone who wants to learn. Players match videos of ASL signs with bubbles containing written English words to pop them.
