PopSign: learn sign language by playing, with AI that sees your signs

PopSign helps hearing parents of deaf children, educators and anyone curious learn sign language through a bubble shooter game. You sign, the phone's camera recognises it instantly, and the bubble pops. No special hardware, no internet needed for recognition.
