Auxel: Auditory Pixel. Arrange auxels in space to generate auditory screen of generative rather than reflective sound patterning.
Some species, like dolphins, have advanced echolocation capabilities,
suggesting the ability to form crisp images from ultrasound reflection
Being that their auditory cortex is so much larger than ours, and that they
it primarily for understanding the world around them, the true
way to share
worlds may be through translation of videos and 3D CAD models into
To do that, we could arrange tiny underwater ultrasound speakers
into a large fine-resolution sheet or film, that produces sounds emanating
them following the clicks of a simulated sound emitter on a Dolphin's head,
it's own click (but much lower amplitude than would be required to produce
reflection), to trick the brain into expecting for a reflection.
The dolphin's brain may then interpret the simulated click as its own
"flashlight", and expect for reflections, which would come after the precise
time expected based on the speed of sound under water, but with
delays from each Auxel, simulating a 3D surface.
The 3D surface thus simulated, may be perceived by a dolphin as a thing
or an immersive environment. So,
we can simulate 3D objects. We could even try to simulate letters, and see
what resolution can a dolphin capture. Can it understand complex CAD
More importantly, if dolphins are able to produce directional sounds, we
also use the Auxels as microphones, and implement an auditory touch
that dolpins could interact with much more naturally.
And, who knows what they could do then.
"Clicks and burst-pulse signals were highly directional" [Mindey, May 03 2019]
"Bottlenose dolphins produce directional, broadband clicks in sequence. Each click lasts about 50 to 128 microseconds. Peak frequencies of echolocation clicks are about 40 to 130 kHz." [Mindey, May 03 2019]

||How would the touchscreen work? Can dolphins project images of sound for it to pick up?
||If dolphins really capable of directional clicking (or at least, with the
distribution maximum at a given point), we should be able to to pick
Similar to how a single finger produces a lot of touches, but we take
distribution maximum or mean that, to resolve to a single pixel.
||With that, different modulation patterns chosen by a dolphin to produce
operation codes. E.g., zoom-in, zoom-out, etc., just like a mouse
||But are they capable of that? I would think they'd just send out an omnidirectional pulse, and listen to what directions the echo comes back from.
||Apparently yes, they are. See links [scitation.org], [seaworld.org]. So,
considering that they can do it sufficiently granularly, one could imagine
them shooting coordinates at the screen.
||Alright then. Good to know.
||But a visual screen is often used to render 2D representations of 3D objects. Could this auditory screen similarly generate 2D representations of 3D objects?
||Also a visual screen can display moving or still images. Could this device use tone generators to create static sound-fields?
||Could you create a VR headset for a dolphin that would
receive the clicks and send back clicks at a time delay to
simulate objects at certain distances?
