Hand Wave turns sign language into text and speech using the camera on Meta smart glasses. It also works cross-platform (iOS + web). Under the hood is a lightweight, open-source neural network trained on Google’s FSBoard dataset and built to run locally across devices (wip).
I’m building Hand Wave to make sign-language conversations more accessible with the camera already on Meta glasses (and other devices too). Let me know what you think!
Love that you built this on an open-source local-first model, since accessibility tools like this should never depend on a paywall or a connection to work.
FSBoard is a fingerspelling dataset if I remember right, individual letters rather than full signs. so is this reading fingerspelled words letter by letter, or does it also handle actual ASL signs and grammar? those are pretty different problems and "sign language into speech" reads like it's promising the second one.
