Hello, I was trying various things, algorithms, neuron networks, took too much time and I am already running out of ideas.
So what I have problem with turning wall surface (or something atleast near surface < 10 cm) touchable!
I can't use depth camera. Or something that is expensive. Probably simple camera, securities cameras with various functions.
What I tried: neuron networks for hand detection (it stops working when projector falls onto hand), opencv finding shadow and hand and trying to determine how each other is close (cause when hand is near wall it shadow almost disappear), various algorithms from removal of backgrounds(objects), differences, motion detection, segmentation and various other which might take too much to explain.
My next idea is to find and figure out how to make it maybe with IR sensors or Ultrasounds sensors that I could put them on ground and point to ceiling and detect when object passes their field of "line" and detect as touch.
