RNS: In a breakthrough study, scientists have demonstrated a technology that allows 3D holograms to be physically touched, grabbed, and pressed — without damaging the display system.
The research, recently uploaded to the HAL Open Archive, showcases the use of elastic materials as a key component in volumetric displays, enabling real-time physical interaction with holographic images.
Traditionally, holograms are generated on fast-oscillating rigid sheets called diffusers.
These are capable of synchronizing thousands of projected images at varying heights to create 3D visuals. However, contact with human hands during oscillation could damage the device or cause injury due to its rigid structure.
To overcome this, researchers integrated a flexible material into the display. Though details of this material remain undisclosed, it allows the holograms to be touched without harming the oscillator or distorting the visuals. This innovation also required the application of image correction techniques to compensate for the natural deformation of elastic materials under pressure.
According to the reports, this marks the first time 3D holographic graphics can be directly manipulated in mid-air by human hands — a milestone that brings science fiction-like interaction closer to reality.
The findings will be presented at the CHI Conference on Human Factors in Computing Systems, to be held in Japan from April 26 to May 1.
While the research has not yet been peer-reviewed, a demonstration video released by the team showcases the technology’s potential, it reported.
Though holograms have been widely used in exhibitions and smart devices, this study pushes boundaries, enabling users to physically engage with digital visuals — much like the interfaces imagined in futuristic films like Iron Man.
