I am trying to code a project that will allow me to use PIR sensors or some kind of thermal sensor to detect hand gestures. I researched this and found that someone has done something very similar. I couldn’t insert the code directly without exceeding the character maximum so here is the code that is used in the project:
My question is how would I manipulate those many lines of binary to get it to detect gestures of my choice. I believe it just breaks down and reads each pixel of data using the TPA81 sensor output. I don’t know how this is possible as it seems some sort of neural network would be necessary for gesture detection. I’d also like to know if this project would be possible just using generic PIR sensors instead of the expensive TPA81 thermal sensor.
