Researchers at the Massachusetts Institute of Technology developed a method to produce holograms instantaneously. The method relies on deep learning and can be run on a smartphone. The team used deep learning to accelerate computer-generated holography, allowing for real-time hologram generation. The researchers designed a convolutional neural network and built a custom database of 4,000 pairs of computer-generated images. To create the holograms in the new database, the researchers used scenes with complex and variable shapes and colours, with the depth of pixels distributed evenly from the background to the foreground, and with a new set of physics-based calculations to handle occlusion.

Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick. Nausea and eye strain can result because VR creates an illusion of 3D viewing although the user is in fact staring at a fixed-distance 2D display. The solution for better 3D visualization could lie in a 60-year-old technology remade for the digital world: holograms. Holograms deliver an exceptional representation of 3D world around us.

MIT researchers have developed a way to produce holograms almost instantly. They say the deep learning-based method is so efficient that it could run on a smartphone. A new method called tensor holography could enable the creation of holograms for virtual reality, 3D printing, medical imaging, and more -- and it can run on a smartphone. Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick.
