Current holographic technologies are nowhere near capable of producing realistic, life-size projections that maintain quality from an array of viewing angles like those portrayed in movies like Star Wars. But things are moving in the right direction with researchers having developed a new type of 3D dynamic holographic display that they claim performs 2,600 times better than existing technologies.
One key limitation to current holographic display technology is that, despite two-dimensional display technologies with tens of millions of pixels, it takes a lot more information than is contained in all those megapixels to generate a sizable 3D image. Using existing display and wavefront modulator technology, which is an optical manipulation device that controls the direction of the light, a tiny hologram about 1 cm in size with a narrow viewing angle of 3 degrees is about as good as it gets.
The more impressive holograms in recent years, like a memorable one of Tupac Shakur, were actually two-dimensional projections, while others require special equipment like augmented reality goggles such as Microsoft’s HoloLens. In essence, these are really just optical illusions.

The researchers from the University of Southampton, working with colleagues in Canada and Italy, claim there is as much evidence for this theory as for traditional explanations for these irregularities.
A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D ‘reality’is contained in a 2D surface on its boundaries.
Until now the bizarre theory had rarely been tested, but recent mathematical models suggest that the mind-boggling principle could be true.

CAE Healthcare announced the release of CAE VimedixAR, an ultrasound training simulator integrated with the Microsoft HoloLens, the world’s first self-contained holographic computer. The announcment marks CAE Healthcare as the first company to bring a commercial Microsoft HoloLens application to the medical simulation market.
VimedixAR delivers an unprecedented simulation-based training experience, allowing learners to interact and move freely within a clinical training environment that is augmented with holograms. For the first time, students will be able to examine 3D anatomy inside the body of the Vimedix manikin. As learners practice scanning an animated heart, lungs or abdomen, they will observe in real-time how the ultrasound beam cuts through anatomy to generate a ultrasound image.
Learners can elevate the VimedixAR hologram above the body to gain an understanding of human anatomy and how its circulatory, respiratory and skeletal structures are integrated. The hologram of the heart, for example, can be isolated and enlarged, rotated, and turned as it floats at eye level. If a learner is struggling to understand a concept, he or she will be able to walk around the hologram to gain a different perspective.

Microsoft’s HoloLens hologram headset systems are already being used in the Australian, Ukrainian and Israeli military forces, and now the US military is also finding a use for Microsoft’s most advanced technology.
In recent exercises, forces from the Marines held a weeklong exercise called Spartan Emerging Technology and Innovation Week at North Carolina. The event featured various training technologies – from quadcopters to augmented reality developed with support from the Office of Naval Research (ONR) to accelerate the development of decision-making skills.

According to her profile, “She is a comforting character that is great to those living alone. She will always do all she can just for the owner.” How thoughtful and sweet. Except she comes with a $2,600 price tag (and her US version will be sold for $3,000). So, caring for her “owner” is the least she can do, right?
The hologram bot is based on a Japanese anime character, but she isn’t going to be the only character for Gatebox. From the looks of the website, the company is going to make other characters available, presumably also from anime.
Azuma’s hologram appears inside the main tube body of Gatebox, projected at a 1280 × 720 resolution. The hardware itself weighs 5kg, has stereo speakers, a microphone, and a camera mounted on top. Azuma is built with a machine learning algorithm, that helps her recognize her “master’s” voice, learn his sleeping habits, and send him messages through Gatebox’s native chat app.
