A Star Wars-style phone which allows users to see 3D hologram images of the person on the other end of the line has been pioneered by experts at Leia Display Systems, a Polish company named after the film’s heroine. To make a call, the person sits in front of a camera which has two lenses and a microphone. The two images formed by the lenses are streamed through to the person on the other end. A hologram machine then projects them onto a screen of water vapour. “At the moment, our holograms are made using machines that are more than six feet high but we are designing smaller versions. We hope to sell hologram telephone devices within the next five years,” Chief executive Marcin Panek said.

In existential news, Tupac isn’t the only one who may merely be a flat holographic projection. Via Nature:

A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.
In 1997, theoretical physicist Juan Maldacena proposed an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter, single dimensional cosmos where there is no gravity.
Maldacena’s idea thrilled physicists because it solved apparent inconsistencies between quantum physics and Einstein’s theory of gravity.
In two papers posted on the arXiv repository, Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues now provide, if not an actual proof, at least compelling evidence that Maldacena’s conjecture is true.
“As we have examined in this special series of Eyeopener reports on psychological warfare in recent weeks, Psychological Operations, or PSYOPS, are every bit as vital to military strategists today as they ever were. In fact, in this age of 24/7 online access and the possibilities for new battlegrounds in the “information battlespace” that it affords, Psyops may be even more important than they have ever been in “winning the hearts and minds” (or at least confusing and stupefying the hearts and minds) of enemies the world over.
In some ways, this is precisely the point. Psyops by their very nature tend to rely on mechanical and technological trickery to deceive enemies or sneak propaganda past their defenses. Some of the greatest military victories in history did not involve fighting or bloodshed at all, but merely intimidation through demonstration of technological superiority.”

Long gone are the days of pushing plastic armies around hand-drawn maps. Today’s military planners deserve technology of the future, and that means nothing less than 3-D holograms will do. Luckily, we have DARPA, ever-ready to step in with a solution. The Urban Photonic Sandtable Display (UPSD) allows up to 20 participants to simultaneously view and manipulate the 360-degree, 3-D image on the table, without having to wear 3-D glasses.
The display can be expanded to as large as six feet, and has a visual depth of up to 12 inches. UPSD is also interactive – battle planners can freeze, rotate and zoom in on the images. They can also print out two-dimensional representations of the 3-D data (seen above) that troops can carry with them on their missions.
Zebra Imaging won the contract to create the technology for UPSD, and DARPA is using LIDAR (Light Detection and Ranging) systems for the data.
In a decade or two, will people view two-dimensional television as outdated, much as we view black-and-white footage today? Japan hopes that the leap forward will occur twelve years from now, with the World Cup being presented in life-size, holographic form, BLDGBLOG writes:

Japan is distinguishing its bid to host the 2022 World Cup with a plan to broadcast the entire thing as a life-size hologram.
“Japanese organizers say each game will be filmed by 200 high definition cameras, which will use ‘freeviewpoint’ technology to allow fans to see the action unfold from a player’s eye view—the kind of images until now only seen in video games,” CNN reports.
British football theorist Jonathan Wilson puts an interestingly spatial spin on the idea: “Speaking as a tactics geek,” he said to CNN, “the problem watching games on television is it’s very hard to see the shape of the teams, so if you’re trying to assess the way the game’s going, if you’re trying to assess the space, how a team’s shape’s doing and their defense and organization, then this will clearly be beneficial.”
Watching a sport becomes a new form of spatial immersion into strategic game geometries.
Richard Gray writes in the Telegraph:
A recently granted patent reveals that Apple, the company behind the iPod and iPhone, has been working on a new type of display screen that produces three dimensional and even holographic images without the need for glasses.
The technology could be used to produce a new generation of televisions, computer monitors and cinema screens that would provide viewers with a more realistic experience.
The system relies upon a special screen that is dotted with tiny pixel-sized domes that deflect images taken from slightly different angles into the right and left eye of the viewer.
By presenting images taken from slightly different angles to the right and left eye, this creates a stereoscopic image that the brain interprets as three-dimensional.
