I played a student project game a long time ago that based itself around this kind of mechanic. It was a horror game set entirely in the dark, and the only way of seeing was by echolocation - you'd click to send out a pulse, and you'd get brief ghostly glimmers of your environment. Importantly, you couldn't directly see anything moving - you'd have to send out another ping if you wanted to see something in motion.

Given that monsters could hear your pings too, it was a wonderful little game of cat-and-mouse deduction trying to figure out where monsters were with as few pings as possible, remembering their patrol paths in the dark, and so on. Really cool and I'd love to see that mechanic in a full game production.

(edit: apparently that full game exists, it's called Perception, and I'm absolutely giving it a shot!)
