holograms

Britney Spears invented hologram technology in 2001 to create a giant three dimensional projection of herself for her Dream Within a Dream tour. Hologram technology has many practical applications aside from 3D projection and can been seen on many state drivers licenses in a simple form as forgery prevention. This invention won Spears the Nobel Prize in Physics in 2002.

GUYS THIS IS IMPORTANT!

A company in Switzerland has figured out how to imprint holograms in chocolate, like the security ones on credit cards. And they’ve done it without additives.

There are microstructures on the surface of the chocolate which bend and scatter the light about, making the hologram image.

I want all of it.

Laser Light and Holograms // Matthew Schreiber

Schreiber’s large-scale light installations have been presented at the Museo Carlo Bilotti in Rome, Fort Lauderdale Museum of Art, Miami Art Museum, Hyde Park Art Center, Chicago, and in art venues in Basel, Switzerland, and Gwangju, South Korea.

Having lived and worked in Miami for decades producing inimitable and inventive sculptural forms with the use of lasers and managing the often intimidatingly grand projects of art icon James Turrell, Matthew moved both his studio and significant others to New York where he now works in close proximity to fellow nomad Daniel Arsham. As ever, Matthew is producing technologically symphonic and beguiling art

New reality: Invisible 3D holograms that can be touched and felt

Immersive, highly visual, 3D environments are now on the horizon after British scientists managed to recreate mid-air sensory experiences by controlling sound waves to project 3-D haptic holograms that can be seen and felt.

A team from the University of Bristol’s Interaction and Graphics research group, using the UltraHaptics, a system for creating haptic feedback in mid-air, were successful in testing several shapes, including spheres and pyramids.

“Touchable holograms, immersive virtual reality that you can feel and complex touchable controls in free space are all possible ways of using this system,” Dr Ben Long, Research Assistant from the Bristol Interaction and Graphics (BIG) group in the Department of Computer Science, said.

In a short time span the researchers managed to leap from simple 2- D outline in mid-air to full shapes, by introducing a LeapMotion which tracks the position of a user’s hands. Then the waves are calibrated to produce projection which, to human touch, feels like different objects of varying shapes. Users can feel 3-D projected objects, get feedback for mid-air gestures and interact with virtual shapes.

Researchers rely on pressure difference created by the machine using ultrasound waves displaced in the air to make the object know to the user. By making many waves arrive at a focal point at the same time, a detectable pressure difference is created at that point, which exerts on a user’s skin when they hit the hand.

"Without haptics, it’s like you’re in a dream and you cannot feel the environment," Sébastien Kuntz, a developers told New Scientists. "You can only look at it, you don’t have any feedback."

The research paper, published in ACM Transactions on Graphics will be presented on Wednesday at the SIGGRAPH Asia 2014 conference later this week. Research led by Dr. Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah and Tom Carter from the University of Bristol’s Department of Computer Science hopes to attract additional funding. Scientists expect the ultrasonic haptic technology to be licensed into various markets including consumer electronics, household appliances and the car industry as well as medicine.

For example, the new technology could “enable surgeons to explore a CT scan by enabling them to feel a disease, such as a tumour.”

“In the future, people could feel holograms of objects that would not otherwise be touchable, such as feeling the differences between materials in a CT scan or understanding the shapes of artefacts in a museum,” Ben Long said.

In November, Tom Carter, CTO at Ultrahaptics, said that, “The Ultrahaptics evaluation programme launch has received a very warm reception from those within the industry. A lot of interest has been registered from several blue-chip organisations and the additional funding will help us to meet the needs of our customers.”

Holocaust stories preserved through interactive 3D holograms

There are an estimated 500,000 Holocaust survivors alive today, but with an average age of 79, they comprise an ever-dwindling part of the world’s population. Their stories, however, will almost certainly live on, thanks in part to innovative efforts like New Dimensions in Testimony — an initiative that aims to record and preserve their harrowing histories through 3D holographic avatars.

Motion-controlled Holograms Are A Real Thing Now

If Minority Report and Iron Man have you pining for a future where we can control glowy blue holograms with the flick of a wrist, pine no more, my friends because the future is now! Robbie Tilton created a gesture-controlled hologram using a computer monitor, a prism and Leap Motion.

Check it out in action below:

Fingers crossed that we’ll all have sweet Tony Stark computer setups within the next two years.

Holograms are amazing technical achievements, but ethically troubling

Five years after his death, Michael Jackson stole the show. He always did when he was alive, and it was no different during Sunday night’s Billboard Music Awards, when a holographic MJ joined a five-piece band and 16 dancers onstage.

He wasn’t the first. When hologram technology emerged two years ago, it seemed like a fad. Now it’s a trend of resurrection so common it might just be the future of the industry.

Giant Hologram of Turkish Prime Minister Delivers Speech

Turkish Prime Minister Recep Tayyip Erdogan couldn’t attend a political party meeting in the city of Izmir on Sunday, so he decided to send the next best thing: a giant hologram of himself.

In a scene straight out of Star Wars, Erdogan’s shimmering avatar, whose real-life counterpart is under siege amid an ever-expanding corruption scandal and the resignations of multiple high-level officials, spoke to an astonished crowd of Justice and Development Party supporters on the need for resilience before municipal elections on March 30.

"We are going to elections in the shadow of attacks prepared by treasonous networks," said the towering, photon-based figure, according to the Turkish newspaper Hurriyet. “I urge all my mayoral candidates to not waste any of their time.”
