PopSign is a bubble shooter style game that teaches basic American Sign Language vocabulary. It is developed and maintained by the Center for Accessible Technology in Sign at the Georgia Institute of Technology.
This game can be built and run on Android/iOS devices using the latest version of Unity 2021 LTS. Newer versions of Unity may not be compatible with PopSign.
