Maybe attempting a more realistic depiction of echolocation could lead to interesting gameplay. There are already some games interesting games based on lidar.
> Researchers from the 1940's through the present have found that normal, sighted people can echolocate - that is, detect properties of silent objects by attending to sound reflected from them. We argue that echolocation is a normal part of our perceptual experience and that there is something 'it is like' to echolocate. Furthermore, we argue that people are often grossly mistaken about their experience of echolocation. If so, echolocation provides a counterexample to the view that we cannot be mistaken about our own current phenomenology.
How Well Do We Know Our Own Conscious Experience? The Case of Human Echolocation
Philosophy aside, bat sonar is different from the senses we possess in an really interesting way. Our eyes have excellent spatial resolution (up/down, left/right), some rough depth resolution (from stereo), and no innate sense of speed. Our brain processes the signal to fake even better spatial resolution, infer more about depth (small vs far away) and more about speed (angle changes, among other things).
Bat sonar is completely different. Spatial resolution is poor. But they have first-class depth and speed information! They don't necessarily know where something is, but know exactly how far away it is, and how fast that distance is changing. One must suppose that their brains synthesize more spatial information from these senses, but that spatial information is still not going to feel reliable.
I'd love to be able to experience that for an hour. To live in this world where distance and speed are primary senses, and cross-range information is much fuzzier. What an incredibly different way to see the world.
