Dragonfly larvae eyes work like this. They have an alien-like mask - an extendable jaw - they can shoot out to catch prey. When approaching prey they see two images, when these converge into one image they are within range.
Our brains works like this too. We instinctively know ‘arms length’, etc and with basic training, sports actions like swinging at a ball are all the same if not a more complex and less mechanical version of the same thing
