New Algorithms Give Digital Images More Realistic Color

In Optica, The Optical Society’s (OSA) journal for high impact research, Qiu and colleagues describe a new approach for digitizing color. It can be applied to cameras and displays — including ones used for computers, televisions and mobile devices — and used to fine-tune the color of LED lighting.

“Our new approach can improve today’s commercially available displays or enhance the sense of reality for new technologies such as near-eye-displays for virtual reality and augmented reality glasses,” said Jiyong Wang, a member of the PAINT research team. “It can also be used to produce LED lighting for hospitals, tunnels, submarines and airplanes that precisely mimics natural sunlight. This can help regulate circadian rhythm in people who are lacking sun exposure, for example.”

New Way To Generate Light Through Pre-Existing Defects in Semiconductor Materials

The discovery demonstrates a practical method to overcome current challenges in the manufacture of indium gallium nitride (InGaN) LEDs with considerably higher indium concentration, through the formation of quantum dots that emit long-wavelength light. The researchers have uncovered a new way t.


A type of group-III element nitride-based light-emitting diode (LED), indium gallium nitride (InGaN) LEDs were first fabricated over two decades ago in the 90s, and have since evolved to become ever smaller while growing increasingly powerful, efficient, and durable. Today, InGaN LEDs can be found across a myriad of industrial and consumer use cases, including signals & optical communication and data storage – and are critical in high-demand consumer applications such as solid state lighting, television sets, laptops, mobile devices, augmented (AR) and virtual reality (VR) solutions.

Ever-growing demand for such electronic devices has driven over two decades of research into achieving higher optical output, reliability, longevity and versatility from semiconductors – leading to the need for LEDs that can emit different colors of light. Traditionally, InGaN material has been used in modern LEDs to generate purple and blue light, with aluminum gallium indium phosphide (AlGaInP) – a different type of semiconductor – used to generate red, orange, and yellow light. This is due to InGaN’s poor performance in the red and amber spectrum caused by a reduction in efficiency as a result of higher levels of indium required.

In addition, such InGaN LEDs with considerably high indium concentrations remain difficult to manufacture using conventional semiconductor structures. As such, the realization of fully solid-state white-light-emitting devices – which require all three primary colors of light – remains an unattained goal.

New deep reinforcement learning technique helps AI to evolve

Hundreds of millions of years of evolution have produced a variety of life-forms, each intelligent in its own fashion. Each species has evolved to develop innate skills, learning capacities, and a physical form that ensures survival in its environment.

But despite being inspired by nature and evolution, the field of artificial intelligence has largely focused on creating the elements of intelligence separately and fusing them together after the development process. While this approach has yielded great results, it has also limited the flexibility of AI agents in some of the basic skills found in even the simplest life-forms.

In a new paper published in the scientific journal Nature, AI researchers at Stanford University present a new technique that can help take steps toward overcoming some of these limits. Called “deep evolutionary reinforcement learning,” or DERL, the new technique uses a complex virtual environment and reinforcement learning to create virtual agents that can evolve both in their physical structure and learning capacities. The findings can have important implications for the future of AI and robotics research.

UPDATED: Facebook changes parent company name to ‘Meta’

Facebook chief Mark Zuckerberg on Thursday announced the parent company’s name is being changed to “Meta” to represent a future beyond just its troubled social network.

The new handle comes as the social media giant tries to fend off one its worst crises yet and pivot to its ambitions for the “metaverse” virtual reality version of the internet that the tech giant sees as the future.

Facebook, Instagram and WhatsApp will keep their names under the rebranding.

Facebook changes its corporate branding to Meta

Well, it’s official. After 17 years of being called Facebook, the social networking parent company behind Facebook, Instagram, WhatsApp, and Oculus has a new name.

Facebook’s corporate entity is now **Meta**.

Facebook creator Mark Zuckerberg announced the change at the company’s AR/VR-focused Connect event, sharing that the new title captured more of the company’s core ambition: to build the metaverse.

“To reflect who we are and what we hope to build, I am proud to announce that starting today, our company is now Meta. Our mission remains the same — it’s still about bringing people together. Our apps and our brands — they’re not changing either,” **Zuckerberg **said. “From now on, we’re going to be metaverse-first, not Facebook-first.”

This Hotshot AI Drone Can Speed Through Complex Environments Thanks To New Kind Of Virtual Training

A team from the University of Zurich has trained an artificial intelligence system to fly a drone in a virtual environment full of obstacles before setting it loose in the real world, where it was able to weave around obstacles at 40 kph (25 mph), three times as fast as the previous best piloting software. Lead researcher Davide Scaramuzza, Director of the Robotics and Perception Group, says the work, carried out in partnership with Intel, could revolutionize robotics by enabling machines to learn virtually.

A paper describing the project, Learning high-speed flight in the wild, was published this month in the journal Science Robotics.

“Our approach is a stepping stone toward the development of autonomous systems that can navigate at high speeds through previously unseen environments with only on-board sensing and computation,” the paper concludes.

Apparently, it’s the next big thing. What is the metaverse?

Facebook has just announced it’s going to hire 10,000 people in Europe to develop the “metaverse”.

This is a concept which is being talked up by some as the future of the internet. But what exactly is it?

**What is the metaverse?
**
To the outsider, it may look like a souped-up version of Virtual Reality (VR) — but some people think the metaverse could be the future of the internet.

In fact, the belief is that it could be to VR what the modern smartphone is to the first clunky mobile phones of the 1980s.

Instead of being on a computer, in the metaverse you might use a headset to enter a virtual world connecting all sorts of digital environments.

Unlike current VR, which is mostly used for gaming, this virtual world could be used for practically anything — work, play, concerts, cinema trips — or just hanging out.

Most people envision that you would have a 3D avatar — a representation of yourself — as you use it.

Virtual reality: A front-row seat to the impact of (un)sustainable behavior

Witness first-hand how your mountain of waste plastic expands over the years and what impact your food has on the rainforests. Virtual reality gives you a front-row seat to the impact of unsustainable behavior. Communication scientists Marijn Meijers and Hande Sungur have developed highly effective virtual worlds that give people an up-close and personal experience of how sustainable and unsustainable conduct make a substantial difference…


You walk around a supermarket and whenever you take a product from the shelves, a pop-up appears with information about the environmental impact of your choice, for example, clearcutting of tropical rainforest to cultivate the palm oil in your chocolate spread. You travel through time to see how much plastic waste your everyday products create in the future, and travel back to see how your mountain of waste shrinks when you make more sustainable decisions.

VR is shown to have a positive effect on sustainability.

The first findings from Meijers and Sungur’s projects are in and the results are positive. “Research into the VR supermarket shows it gets the message across more effectively and gives people the feeling that they have control over the problem,” says Meijers. “They clearly see how buying eco-friendly products contribute to a more sustainable world and that unsustainable choices have a negative effect. This positive effect on the participants’ behavior continued to be reflected in their real-world shopping habits after two weeks.”

Ray Kurzweil — Immortality by 2045

Ray Kurzweil — Singularitarian Immortalist, Director of Engineering at Google, famous inventor, author of How to Create a Mind http://GF2045.com/speakers/.

A world-class prolific inventor and leading futurist author, “the restless genius” (Wall Street Journal) points to 2045 for the technological singularity when A.I. will surpass human intelligence in his New York Times best seller The Singularity is Near, Amazon’s #1 book in science and philosophy.

In this video Ray Kurzweil discusses his predictions about radical life extension, singularity, life expansion and the imminence of physical immortality. He invites participants to the second international Global Future 2045 congress (June 2013) http://www.GF2045.com.

“If we have radical life extension only, we would get profoundly bored, we’d have profound existential ennui, running out of things to do, and new ideas, but that’s not what’s going to happen. In addition to radical life extension, we’re going to have radical life expansion, we’re going to have millions of virtual environments to explore, we’re going to literally expand our brains.”

“We’ll be routinely able to change our bodies very quickly, as well as our environments in virtual reality, but it will feel very real. We’ll ultimately be able to do that with real reality too, like self-organizing swarms of nanobots that can link themselves up into a virtual body.” says Ray Kurzweil.
