“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
