You're welcome!

good explanation, a query, in addition to the detection, we can count the number of hands that are in the video or in an image, for example, if several people appear, yes, how would the count be carried out or within which ml5 variable is this data stored?

[@pippinbarr]

Hey Miguel - hmm, at least in my memory Handpose in ml5 will only do one hand at a time. It's worth looking at something like MediaPipe if you want to do more sophisticated hand tracking.

[@mariangelrivero7687]

This is amazing! If I wanted to make the dot stay in place for example when I close my hand and make a new dot appear opening my hand again do you think I could make it happen with ml5?

[@pippinbarr]

Oh for sure. You could, for instance, calculate the distance between all the tips of the fingers and if it's small enough consider that a "closed hand" and lock in the current dot? Honestly I often recommend getting to grips with the MediaPipe hand model stuff just because it's a bit smoother and more reliable; but you could get that idea done with ml5 I think, yeah.

@@pippinbarr Do you think there is a way I could contact you to have a more in deep explanation? I have been stuck and I am scared I wont be able to accomplish the goal and I have tried everything

[@avirads]

Is the model downloaded each time from internet? Can it be made offline to preserve bandwidth?

[@pippinbarr]

Hey sorry I missed this. Yeah, it'll be cached by the user's browser. But you can also store the model offline I believe with a bit of tinkering.
