@whale-av Hi, I have created the "field game", now the only thing I miss is the hands detector. My teaches suggest me to create something that observes the different position on my hand with one second or more delay; with this I can discover the strength to apply to the ball. But I don't know if there are already examples or something.
Please help me, I feel I'm so close to the solution but I'm so confuse
["tavolo" means table and "campo" means field]

Goodmorning everybody!
I'll be completely honest with you: I have to create a patch for a university exam and I have no idea how to do it; my project is a sort of air hockey table but, instead of playing with real objects, this game is played with the projection of the disk and the shadows of the hands. I'm asking your help because I don't know how to make pure data (linked with a webcam) interact with shadows…
I'd be so glad to receive son advices, thanks for your attention
