Cool but how is the math used to recognize gestures?
It appears to be a dot product of a vector field and the curve vector (i.e. a line integral). I think this approach can't handle certain cases where a path is retraced in opposite directions, like with the handwritten letter 't' or 'i'. Perhaps curvature integrals could be added as well to improve it. Overall seems to work quite well!

I think it works quite poorly: https://imgur.com/a/oDpVkZ6

Looks like you draw your digits differently. It's "trained" to my style. Try making your own glyphs and see how it does.
Perhaps, but how does that 9 I drew ever map to a 6?
It was ridiculously hard to get 4 to work, is this a limitation of the algorithm or just something with the implementation?
How do you draw your 4? The one I used is the "one stroke" 4 where you draw it from left, top, and then down.

I think I found out the trick though: if you make a sharp 4 like the font you get random results but if you just make smooth loop of it (almost looks like a tilted roller coaster) it gets it every time.
