A tactile 3D display, created with sound

[@spawnundead]

I'm from Brazil and I really enjoyed the study! Something that came to mind would be how interesting and beautiful it would be to simulate our Solar System in this scientific study! It would be beautiful!!

[@evilovesperry]

Why? Thats a waste for everyone. Leave that to a third party dev this is one of the few ways I'll accept ai existing

[@L3AF]

Holy shit just imagine the possibility of the future for this tech!

[@Innomen]

I feel like this is gonna be the approach that sticks.More beads, faster, larger area, better speakers. Large room for improvement from every direction. Imagine stepping into a room of these.

[@SeeNickView]

Yeah safety would be paramount. Depending on the refresh rate/particle velocity of the hologram, though, as well as the particle rigidity, it might hurt I can imagine a person walking into a room where water droplets are used as the particle so that impact isn't too harmful. They can put their hand in front of the sound pattern and "feel" the presence of simulated object at that point. Obviously the water droplets arrested by their hand would need to be replaced by some sort of emitter with constant particle/image parity monitoring

[@franciscopoblete1609]

Imagine this technologic evolves to holograms calls in the future

[@kanishka.b8550]

Francisco Poblete yeah those beads will fly through ears!

[@BManStan1991]

It probably will lead to holograms tbh. Give it a couple years to get out of the lab.

[@vinamerica]

The technology is amazing. The problem is the cinematographer that doesn't know how to set up the shutter of the camera to show how it really looks. We are living a time in our society where everyone wants to do something without the basic knowledge. That's our decay as humans. Spoiled Ego.

[@AndyPorter79]

@@kanishka.b8550 more like instead of having a video call on your laptop you'll have a holo-call standing in your living room facing a hologram of the person you're having a call with. Kinda like a Star Wars Princess Leah hologram recorded msg played by R2D2

Will be dope af for edm raves bro ! So psyched for this to become a new technological feat. Only the future knows what other applications will derive from this method

[@Personnenenparle]

Is there some materials that are "transparent" to some frequencies? Could you levitate 2 beads using different standing waves frequencies?

[@TheOtherSun]

Absolutely

[@cryptoworldgames]

yes you can make 1 bead with stealth reflection technology and normal bead is 1 and stealth bead is 2. if anyone uses this idea, i want 10% of the royalties

[@AgentPothead]

This is awesome. I can't wait to see where this technology ends up.

[@hftoday]

This is quite intriguing. I can't wait to see what the future holds for us.

[@gibohnee]

This was 4 years ago... where are we now? That's an eternity in tech! My current thoughts: Each vertical shaft created by the lower and upper ultrasonic emitter (speaker) are like strands of string. You can have multiple 'voxels' by adding more beads vertically. We should technically be capable of 1000s of voxels by now, perhaps using extreme light-weight RGBWW LEDs custom designed into a hollow spherical structure that has wireless power receivers built into them. This would allow them to be activated by varying magnetic field induction, and the cameras tracking the voxels in real-time would feed that data into the color map for the 3D 'scene'.

[@marielizysurourcq]

This tech can only move one bead very fast and then uses color flashes at the right moment. Still limited but we also have to remember that the effect is better when seen with your eyes than filmed

[@sergiosierra6849]

i don't think This would work in space or vacuum because sound waves don't propagate there, so i guess the best option is still the laser one wich got them inspired.

[@jalexanderevans]

How scientists at BYU can invent something like that laser display and then carry on believing the angel Moroni traveled to upstate NY to give Brigham Young gold plates to translate is beyond me. That's same high-level compartmentalizing of intelligence.

[@Ellocox70]

Yo, imagine seeing this to display videos and advertisements like on akira or bladerunner.

[@imranbug81]

How do they get funding for all these stuff?

[@okashaarshad2371]

Do you any plans to release the FPGA code?

[@magscorp13]

Plot twist, a technology similar to this, applyied at the smallest scale is what allow this simulation (our world) to create all kind of 3D shapes and experiences. Just instead of small plastic beads, we have quantum waves/particles.

[@bigchungus1592]

incredible

[@mitchmagno29]

can this thing create a touchable hologram?

[@gibohnee]

Not this iteration, but yes, about 100+ iterations down the line it is certainly possible. The voxels will most likely evolve from styrofoam beads into custom RGBWW LEDs powered wirelessly. And from there, a method for 'attaching' voxels to other voxels, magnetically or mechanically will be realized. Then we wouldn't be too terribly far from having the tech to pull off a full size Star Trek style holodeck.

[@shtml54]

If you film or edit at 25 frames per second. There will be no flicker.

[@artemirrlazaris7406]

I agree Overunity. The scifi novels in the 80's and some movies, demonstrated a troph filled with liquid, sand, or using interference light patterns, to create holograms. each has been brought into reality as an act. Liquid, offers an interesting glass and solid field. Sand/dust/ dependent size mater offers, touch feed back so one could create an entire room, Real challenges is structure supports so make a vibrating bridge and then put an object on it, and see x surface area for fall through or giving buoyance, because technically its a solid mimicking a liquid state, one could then drown in sand, but its the limited language ot describe these, its detests e greatly is the lack of terms that describe teh active dance of matter properly.. Technically everything behaves like a liquid, so we have state changes at temperatures, but this is difference ot movement, there isa word that comes ot mind but it disappeared... The level of matter dissociation from 0 to 1 and everything as a fraction between. 1 being solid, 0 is to such a spread state that its like colorless gas. LIght doesn't give back feed back, other then heat... Newtonian fluid is of interest to this application. It gives a new level to gaming, and exploration and a mapping systems. Allowing to give a map that convey information without having ot read the plateau lines. Including tracking Here's an error of word, but 2800-3400... year... just state how far away, because this would go through a process of learning... then the system... there is a energetic state with magnetic sound vibration... could create entire rooms looking realistically.. but maybe it already exists. lol Dangers are what is the reaction to falling through microvibrations? I don't think muchcould happen, unless prolonged into it, but hmm.

In 3D image you can't See the whole picture in just a look from a particular position....

[@OverUnity7734]

I could see this using the already existing dust in a room to create the images rather than having to supply polystyrene beads.

[@davidandrex2]

it would be a cool way to clean your house. put a sound box in a room, turn it on and all dust gets drawn up to it. makes a hologram show then bags it up for you.

[@SeeNickView]

Plasma could be feasible. I reminisce about plasma globes that you see at museums where putting your hand or finger on the globe surface draws the plasma to that location. Those plasma arcs are mainly electrons, no? I wonder if matter decay would be a bigger issue when trapping the plasma for a long time rather than actually trapping it in the first place Light itself could also be feasible, given that I think it was UCLA a couple years ago who were able to slow down a light ray enough to capture its propagation (albeit in a fluid/medium and not just vacuum). You might need strong magnetic fields to steer the waves into specific interference patterns, or the right kind of cavity. But then again we see light in our eyes/through a camera because waves excite our receptors therein, so I'm not sure if that fact would undermine any wave patterns we could manage to actually create. Not sure if the wave itself, if trapped, would reach our eye and allow us to register/perceive that the wave is actually trapped there. It might still be invisible. Another way to do it would be to create miniscule (at micro- or even pico-level) spherical 3D "pixels". You could have these things either be electronic LED emitters that emit different RGB colors depending on some sort of RF/microwave signal, or just make the 3D pixels out of a material that reacts to the local Infrared wave pattern it experiences at each location of its movement. So, what I'm saying is layering an IR field on top of the acoustic field so that as the 3D pixel moves in space according to the acoustic pattern, but then change colors according to the heat pattern. These 3D pixels would work better than trapping light itself because they theoretically *emit* light themselves, which then has a chance to reach our retinas and be processed by our brains into color Edit: finished my thoughts Edit 2: I just realized that you could similarly overlay an RF/microwave field on top of the acoustic field just as much as the IR one, in theory. Then yes you could either have "electronic" spheres or cubes as the 3D pixels, or conversely some sort of organic/inorganic compound structure that rearranges itself and emits different frequencies of light according to the localized IR field it experiences The RF/microwave idea may or may not be the same as the plasma idea, if my assumption is right in that plasma is actually composed of electrons and that the electrons take the place of the "inorganic compounds". So many possibilities!
