Description
Hi!I have relatives that speak sign language, and always found it odd that despite unbelievable advances in AI in recent years, the problem still felt somewhat neglected.Especially with the advent of wearable tech; to my knowledge, this is the first project that integrates the meta glasses w/ fingerspelling translation software.As for the technical aspect, I trained a neural net on Google's FSboard dataset modeling a CNN + GRU temporal encoder architecture (trained with CTC), and then decoded the output with CTC beam search and a KenLM language model to solve some of the deficiencies with my model.I've also made it cross-platform (web + iOS, with both web screen sharing and the ability to use non smart-glasses). The project is entirely FOSS.I'm currently working on making the on-device model work cleanly, but unfortunately performance takes a bit of hit on lower-end devices so for now I've opted for hosting the model on Modal.There's so much room for improvement, but I'm happy with this starting point. Let me know what you think, and check out the YouTube demo!

Could you build this?
Partial Building the client integration to fetch frames from smart glasses is approachable, but real-time continuous sign language translation requires specialized video-based gesture recognition models that go beyond standard LLM vision APIs.
What it would actually take: Architecture involves a mobile relay app streaming camera frames from Meta smart glasses to an edge or cloud pipeline combining MediaPipe or a custom spatial-temporal graph convolutional network (ST-GCN) trained on sign language datasets (e.g., WLASL). The hard part is low-latency continuous recognition of rapid finger-spelling, motion trajectory, and facial expressions, requiring custom ML computer vision engineering.
Discussion
14 comments analyzed.
Competitors mentioned: DeepMind's multilingual sign-language-to-text model
Concerns raised: Conflating fingerspelling with full sign language, Oversimplifying sign language complexity (facial expressions, body positioning, classifiers, non-manual markers), Risk of perpetuating misconceptions about Deaf culture without community input, Over-promising capabilities beyond what the model actually does, Lack of understanding of disability community needs before building for them
Feature requests: Encode facial expressions and non-manual markers in model, Handle full sign language beyond fingerspelling (handshapes, orientation, movement, location), Support multiple sign languages with proper cultural context
