Notbot ghost joystick

I’m not too sure what the logic is behind a joystick that plays by itself without any human input. What you see here is a demonstration of the Notbot (or so its called) taking a stroll through Quake 3. Looks pretty creepy, and I’d certainly be freaked out if I ever saw my own mouse moving by itself and my keyboard tapping away in the middle of the night without anybody else being at home. Perhaps Casper and his friendly cohort love gaming as much as we corporeal humans…
