Holograms who can be handled physically came out of science fiction And in real life thanks to a breakthrough in mixed reality technology.
In a new study downloaded on March 6 to the Hal Open ArchivesScientists explored how three -dimensional holograms could be seized and stung using elastic materials as a key component of volumetric displays.
This innovation means that 3D graphics can be interacted – for example, enter and move a virtual cube with your hand – without damaging a holographic system. Research has not yet been evaluated by peers, although scientists have demonstrated their results in a Video highlighting technology.
“We are used to directing the interaction with our phones, where we press a button or drag a document directly with our finger on the screen – it is natural and intuitive for humans. This project allows us to use this natural interaction with 3D graphics to take advantage of our innate 3D vision and manipulation capacities”, adre the study author of study author of the study author of the study ” Asier MarzoA computer teacher said at the Navarra public university in a statement.

Researchers will present their results at the CHI conference on human factors in computer systems in Japan, which takes place between April 26 and May 1.
Holographic media threshing
While holograms are not new today – increase public exhibitions or sit at the heart of intelligent glasses, for example – the ability to physically interact with them has been recorded in the field of science fiction, in films like “Iron Man” by Marvel.
The new research has been the first time that 3D graphics can have been handled in the air with human hands. But to achieve this, researchers had to deepen the functioning of holography in the first place.
At the heart of the volumetric displays that support holograms is a diffuser. It is a quick, generally rigid oscillation sheet on which thousands of images are projected synchronously at different heights to form 3D graphics. This is known as the hologram.
However, the rigid nature of the oscillator means that if it comes into contact with a human hand while oscillating, it could break or cause an injury. The solution consisted in using a flexible material – whose researchers have not yet shared the details – which can be affected without damaging the oscillator or cause the image deterioration.
From there, this allowed people to manipulate the holographic image, although the researchers also had to overcome the challenge of deformation of the elastic material when touched. To get around this problem, the researchers implemented the image correction to ensure that the hologram has been projected correctly.
Although this breakthrough is always at the experimental stage, there are many potential ways to be used if it is marketed.
“Screens such as screens and mobile devices are present in our lives for work, learning or entertainment. Having three -dimensional graphics that can be directly handled presents education applications – for example, visualize and assemble the parts of an engine,” the researchers said in the press release.
“In addition, several users can interact in collaboration without the need for virtual reality headsets. These displays could be particularly useful in museums, for example, where visitors can simply approach and interact with the content.”
