“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: https://hal.science/hal-04981007v1/file/FlexiVol___CHI25%20%282%29.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.

Don't judge until you try some ghost dick for yourself.

There are touchable graphics at the expo in Osaka. I think they‘re created by sonic waves and feel „fluffy“.

i guess they just mean like a 2D “touch”screen.
