100%. Wonder how soon this will become automated though? Since ASL seems like an image recognition task, and AI models are getting pretty good at that.
in practice that's all difficult, if at all possible -- but just sayin; we have decently good speech interpretation at this point, perhaps we aren't far from self-training ASL against something similar.
One of the more common examples from teachers is the sign for SLOW. On the west coast, we sign it as the flat palm being pulled slowly back along the extended non-dominant arm. But in the south and parts of the east, it is signed as the Y sign, thumb against the cheek, being tilted forward.
The way you fix this casually is to ask the other person to finger spell or mime what they meant. I can't see AI being able to do that well for a while but maybe..?
Not trying to be trite, but I imagine you don't know ASL. It is an extremely loose and context dependent language really. I am sure it can be done eventually, but I still think it's very far off in terms of recognition. Would love to find out more about the state of the art for ASL or BSL recognition though.
