What you describe already exists, a CV driven cheat that uses mouse inputs / screen reading. Would also work for League of Legends "auto-hit" or "aura" cheats that will automatically trigger an ability aimed perfectly if someone enters a radius around you. However: This would possibly require a hardware peripheral and you could analyze the inputs a-la captchas.
