The demo doesn't seem to work on my chromebook. Maybe it's too underpowered? Web page doesn't say anything after `Warming up...` and the latest message in the browser console is: Setting up wasm backend. I expected to see a message from my browser along the lines of "Do you want to let this site use your camera", but I saw no such message.

Thank you for the feedback. I would like to fix this but I neither own a Chromebook nor does it seem like I can use a platform like browserstack to reproduce the issue (didn't find Chromebook as available device there). If you would like to help debugging the issue you can open a GitHub issue here: https://github.com/handtracking-io/yoha/issues

Demo keeps crashing on iOS.

Thank you for the feedback. I can confirm there seems to be an issue with iOS/Chrome and created a GitHub issue for it (https://github.com/handtracking-io/yoha/issues/5).

Note that if you were trying iOS/Safari and not iOS/Chrome there is nothing that can be done due to a limitation that is documented in the section "Discussion" here: https://developer.apple.com/documentation/webkitjs/canvasren... Will document this.

Could it be used to translate sign language signs to written or spoken words, I wonder.

Thank you for the question. Since a similar question was asked already let me refer you to this comment: https://news.ycombinator.com/item?id=28830943

Thank you for the pointer that I had overlooked.

Earlier quoted context omitted.

Thank you for this inspiring question. For interpreting sign language you need multi-hand support which YoHa is currently lacking. Apart from that you likely also need to account for the temporal dimension which YoHa also does not do right now. If those things were implemented I'm confident that it would produce meaningful results.

It's worth noting that movements of the mouth are extremely important in ASL (and other sign languages) and so this probably isn't as useful as it might seem at first.

Indeed! TIL. https://en.wikipedia.org/wiki/Mouthing
