Scientists build 3D floating 'e-ink' display

The promising technology enables a three-dimensional image to be suspended in mid-air using sound waves.
Developed by researchers at the University of Sussex, the display is comprised of a grid of voxels which appear as multi-colored spheres that can be moved around and manipulated.

It works using a set of ultrasound speakers which "create high-pitched and high-intensity sound waves that are inaudible but forceful enough to hold the spheres in place."

While the technology is currently very limited, in the future it may be possible to create larger displays capable of showing highly detailed three-dimensional shapes and images.

"We also want to examine ways in which such a display could be used to deliver media on-demand," said researcher Sriram Subramanian. "A screen appears in front of the user to show the media and then the objects forming the display fall to the ground when the video finishes playing."

An in-depth demonstration of the technology can be viewed below.

wow, this is what a hologram should be .

Wow again! Way over my head re the technicalities but exciting stuff.

I wonder which are the side effects of being exposed for prolonged periods of time to high pitch, high frequency sound waves. For sure you wouldn't be able to watch the tv with your dog anymore!†

Unless I missed it in the article, it didn't say how large or how far the field goes outside the equipment.† Maybe it will be OK†† As the article said, this sin't ready for prime time yet.

I missed it too, †that's why I was wondering.† If I got it right, you should be able to interact with the hologram, so theoretically it should be "open" let's say, and thus my concerns about exposure.† † If you think about it, †we have high frequency devices to keep mosquitoes away, †so possibly it's harmless.† † I guess it depends on how powerful the sound waves are, but as you wrote, it's still in its infancy, so time will tell.†

How fun is that!?

This is very old news. This tech has been around for decades. It uses a standing wave to suspend styrofoam beads and is not practical for much of anything. All these guys did was make an array. You'd need tens of thousands of them working together to create any decent resolution and a slight breeze will disrupt the whole thing. There are many other more practical hologram technologies already in existence or in the works. It's neat, but will never be more than a novelty.
