MLNI – Chinese Sign Language- Eszter Vigh

Southern Chinese Sign Language

I rode the metro with two ladies speaking sign language. I barely know enough Chinese to function, let alone Chinese Sign Language. So I did some research!

Turns out, just like China has many Chinese dialects, they have more than one sing language. Chinese sign language is split into North and South. Northern Chinese Sign Language is based off of American sign language, and Southern Chinese Sign Language is based off of French sign language. 

Since we live in Shanghai, in this case I am looking at Southern Chinese Sign language. I trained 20 different hand gestures basically using the Rock,Paper, Scissors base KNN. 

It kind of works? I works for one iteration and then stops. So I think this is because I have too many buttons but I cannot be sure! It’s okay! It is progress. At least the recognition is very accurate. 

It worked with the three buttons. I didn’t change any of the code other than adding additional buttons. Because I can’t get the confidence to work it is harder to get additional interface things to work. I am hoping to get the issues sorted out as soon as possible. 

Once those issues are sorted I will come back to this post and adjust with the final product. This issue with the code seems to be common. I want to see why it happens, as adding additional buttons seems rather straightforward.

So, upon meeting with Moon, I worked through the issue, discovering that the broken HTML was due to a single spelling error in terms of confidence detection with one of the signs. I subsequently fixed it and retrained the entire data set, with about… 100+ examples each. Some signs work standing up, others work sitting. 

I worked on some simple CSS to make the interaction clear, in this way it makes it less cluttered as well. The emojis are meant to be hints, and the detection is meant to show people that their actions, their hand gestures have meaning. 

I was going to add a guessing element… to have a randomized emoji appear, but I thought the learning part of this should happen with the video I included above. This is more just to practice different signs. 

That is something I would further improve if I were to make this into an actual project beyond just a homework.
