Squid Games Body of Movement Detection

i decided to re pose a small project that was already done by somebody else, but i added a post detection to it. Using the worm cam fid, i cannot play this game where, you know, when i can move, i get closer to my computer. But when i'm not supposed to move, then i do some calculation in injava script to check that ther let's say the delta between the position of different points, my body is not moving too much. So and if i move, then I fail in the game. And if it detects that i'm not moving, so,you know, if i'm playing the game properly, then it lets me do another round until
