Gesture recognition

Created Thursday 09 November 2023

My idea is to create tiny gesture recognition modules that can be easily used with Arduino, provide reliable readings and do not require any libraries. But how to achieve best gesture recognition ratio using APDS9960 or similar infrared gesture sensors? I've tested several approaches, and finally created an algorithm with nearly unbeatable recognition performance.

Here are aprroaches I've tested:

There are many approaches to pattern recognition. My approach is basically projects four photodiodes amplitude vector waveforms (a1,a2,a3,a4) to other dimensions:
