Developers from the University of Navarra in Spain have created 3D hologram the machine floats in the air and is easily controlled by hands.
It is noted that the team of researchers led by Elodie Buzbib managed to create three-dimensional 3D graphics, which can be moved by hand.
«What we see in movies and call holograms are usually three-dimensional images It is a graphic that floats in the air and can be viewed from different angles without the need to wear virtual reality glasses. It’s called true 3D graphics», — explains Elodie Buzbib.
According to her, created by scientists display type uses a «comes and interacts» approach. That is, users can simply walk up and start interacting with the graphic projection. For example, companies such as Voxon Photonics and Brightvox Inc. are already developing and offering volumetric displays, but their designs do not allow direct interaction with images.
«We’re used to interacting directly with our phones, pressing a button or dragging a document directly with our finger on the screen – it’s natural and intuitive for people. This project allows us to use this natural interaction with 3D graphics to tap into our innate 3D vision abilities», — adds Elodie Buzbib.
The development was implemented as part of the InteVol project led by researchers from the University of Navarre and funded by the European Research Council. The display directs the projection onto a fast-moving surface called a diffuser, which oscillates at a speed of 2,880 images per second. The human eye perceives these multi-layered images as a full-fledged a three-dimensional object that floating in the air.
However, conventional diffusers are very hard. If you come into contact with them and try to touch a moving surface, you can break or injure your hand. For this reason, the developers replaced the rigid sheets with those made of more elastic materials Elodie Buzbib also noted that elastic materials deform quickly and the image needs to be corrected afterwards However, the team has developed a working system that ensures natural interaction The development of Spanish engineers allows you to compress and move a three-dimensional projection.
«Displays such as screens and mobile devices are appearing in our lives for work, study, or entertainment. The availability of three-dimensional graphics that can be directly manipulated has applications in education — for example, visualizing and assembling engine parts Several people can use these 3D displays simultaneously without any virtual reality headsets. This makes them ideal for collaborative work», — the developers note.
The results of the work are published on the website University of Navarre
