If you think augmented reality is only fun and games, consider that we’ve already witnessed the first known police action taken against hologram technology. During the summer of 2015, a performance by controversial gangster-rapper, Keith Cozart, was shut down when local police discovered the musician was broadcast as a hologram into a benefit concert in Indiana—close to the border of his home state of Illinois.
Cozart, who goes by the stage name “Chief Keef,” is from a rough neighborhood in Chicago, and has ties to local gangs as well as a criminal record including felony gun charges. His music, which glamorizes a gang lifestyle and violence, has prompted public officials—including Chicago mayor Rahm Emanuel—to pressure music festivals to avoid inviting Cozart because they say it poses a “significant public safety risk.”

- A new phone concept designed by Philippe Starck and Jerome Olivet is a voice activated, gelatinous, transparent futuristic vision of where smartphones could go.
- Continuing with the trend of subtracting hardware, the phone contains no screen but will be capable of projecting 3D holograms.
The words gelatinous and smartphone might not seem like they belong in the same sentence together. In fact, they barely belong in the same dictionary together. But the Alo smartphone, an unfinished, unreleased technology, is described as a gelatinous, ergonomically shaped to fit the hand well, voice-activated and controlled smartphone. Designed by Jerome Olivet and Phillippe Starck, this design promises to be the future of smartphone technology.
This phone is unlike any current model, and its most notable feature (that we know of yet) is that it will be able to project holograms. Yes, you read that right. Any messages, photographs, or even movies would be able to be viewed as 3D holograms. And while an entirely voice-controlled smartphone might seem a little bit strange and difficult to use, it is supposedly designed to be remarkably user-friendly.

The advantage of Daqri’s chip, the company says, is that it can create holograms without the need for complex optics. On a silicon wafer, a tiny grid of tunable crystals is used to control the magnitude and time delay, or phase, of reflected light shined at the surface of the chip from a laser. Software adjusts the crystals to create patterns of interference in the light, resulting in a three-dimensional light field.
In experiments, the team has used the chip to create solid objects by projecting holograms into containers of various light-activated monomers. It can currently make small objects, such as a paper clip, in about five seconds—a process that could take a normal 3D printer several minutes.
A startup called Daqri has technology that can print solid objects faster and also powers a new kind of head-up display.

A wavefront-shaping technique has been used to create a dynamic 3D holographic image with a viewing angle of 35 degrees in a volume of 2 cm in length.

Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the ‘afterglow’ of the Big Bang), have found that there is substantial evidence of our universe being a vast and complex hologram. A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence supporting a holographic explanation of the universe. The researchers from the University of Southampton (UK), University of Waterloo (Canada), Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy) have published their findings in the journal Physical Review Letters.

As strange as it may sound, the universe actually may be a hologram, according to a recent study published in the journal Physical Review Letters.
Despite our knowledge of the universe, cosmologists have never been able to agree on a single unified model. This is because many current versions describe the cosmos with either general relativity or quantum theory, and neither of those work well together.
In an attempt to bridge this gap, a team of researchers from Canada, England, and the United States, argued that a holographic explanation of the universe could provide a set model, UPI reports. This is because it is able to account for irregularities in the echo of thermal energy leftover from the Big Bang, known as the cosmic microwave background.
