This project uses the position of the tip of your nose relative to the point between your eyes to determine where you are looking on the screen. This can be used to maybe make something activate if you point your head at it or something. This is not an eye tracker. You have to turn your whole head to get an effect. 100% backpackable. Don't worry, there are no cloud variables. Nobody else can see your face. Only you can.
Use the "calibrate" block to recalibrate it. Mess around with the sensitivity to your liking. The variables of where you are looking at are called "LookingAtX"/Y. I had this idea entirely on my own and created all the code. I did not watch any tutorials and I have not seen anyone else do this. If my code is similar to anyone else's, it is simply a coincidence.
