“What we see in films and call holograms are typically volumetric displays,” said Bouzbib, the lead author of the work. “These are graphics that appear in mid-air and can be viewed from various angles without the need for wearing virtual reality glasses. They are called true-3D graphics.”
Here is a link to the PDF that details the work: hal.science/…/FlexiVol___CHI25 (2).pdf

i took “touchable” to mean you could literally feel the shape with your senses, but it appears what they are saying is it’s a way to interact with it, via pass through in various ways, etc. still pretty cool though
Perhaps pokable is a more apt description.
“Pokable” was my first hope too, but it doesn’t look so.

That’s rich coming from the ghost fucker.
Don’t judge until you try some ghost dick for yourself.
Words to live by, brother
i guess they just mean like a 2D “touch”screen.
There are touchable graphics at the expo in Osaka. I think they‘re created by sonic waves and feel „fluffy“.
you look lonely… I can fix that.
I’m working on a 3d realtime hologram that you can fuck, with the obvious tech limitation that, since you can’t touch it, it feels like slamming your dick into open air
i call it “your mom”
Enter the fleshlight. No, please! C’mon in! The gears are churning and the gel is moist!

Second Technician Arnold J Rimmer reporting for duty.
Nerd here. That's soft-light Rimmer. He didn't get the hard-light drive until they met Legion in season 6.
The only things he could physically interact until then were other holographic things provided by Holly or whatever his light bee was programmed to supply.
E-e-except where the script writers made a mistake. At one point he was able to smell something burning which definitely shouldn't have been possible. Unless Holly simulated it for him anyway. That sort of shenanigan would be right up Holly's alley now that I think about it.
(For the uninitiated, Holly is the sarcastic and dry witted AI in charge of supervising all ship computer operations. And he's allegedly senile after 3 million years in deep space. Allegedly.)
I could not find a hard light Rimmer saluting, so I wad forced to use soft light Rimmer. And I had just watched S6E2 Legion a couple hours before posting this.
that is old. remember 2014: newatlas.com/…/35032/
That research was more about the haptics. This new research is more about projecting a volumetric hologram that can also be interacted with directly.
This one projects the image onto a bunch of vibrating rubber bands. I don’t think there’s a long term market for this. It’s a clever idea though that fixes the hazards of a solid diffuser (like those godawful fan-based volumetric displays).
I’m not sure touching is important. Have a touchpad for rotation if you are too lazy to physically move around object. Buttons for 45^*^ rotations at a time would be even cheaper. Then, if purpose of display is to have many people around it, for “presentation purposes”, then a 2d screen and 3d rotation software will show objects in much better resolution and cheapest of all, while focusing on angle that matches presentation point.
