New photonic liquid crystals could lead to next-generation displays

Posted by in categories: electronics, virtual reality

A new technique to change the structure of liquid crystals could lead to the development of fast-responding liquid crystals suitable for next generation displays—3D, augmented and virtual reality—and advanced photonic applications such as mirrorless lasers, bio-sensors and fast/slow light generation, according to an international team of researchers from Penn State, the Air Force Research Laboratory and the National Sun Yat-sen University, Taiwan.

“The liquid crystals we are working with are called blue-phase liquid crystals,” said Iam Choon Khoo, the William E. Leonhard Professor of Electrical Engineering, who is the corresponding author for this article. “The most important thing about this research is the fundamental understanding of what happens when you apply a field, which has led to the development of Repetitively-Applied Field technique. We believe that this method is almost a universal template that can be used for reconfiguring many similar types of liquid crystals and soft matter.”

Blue-phase liquid crystals typically self-assemble into a cubic photonic-crystal . The researchers believed that by creating other structures they could develop properties not present in the current form. After nearly two years of experimentation, they realized that by applying an intermittent electrical field and allowing the system to relax between applications and to dissipate accumulated heat, they could slowly coax the crystals into stable and field-free orthorhombic and tetragonal structures.

David Pearce — Experience Machines and Hedonic Treadmills

Posted by in categories: biotech/medical, ethics, virtual reality

“…consider Robert Nozick’s thought-experiment in conjunction with Felipe De Brigard’s inverse experience machine argument: “If you like it, does it matter if it’s real?”


Does Nozick’s experience machine prove anything?

The Ouroboros Code: Bridging Advanced Science and Transcendental Metaphysics

By contemplating the full spectrum of scenarios of the coming technological singularity many can place their bets in favor of the Cybernetic Singularity which is a sure path to digital immortality and godhood as opposed to the AI Singularity when Homo sapiens is retired as a senescent parent. This meta-system transition from the networked Global Brain to the Gaian Mind is all about evolution of our own individual minds, it’s all about our own Self-Transcendence. https://www.ecstadelic.net/top-stories/the-ouroboros-code-br…etaphysics #OuroborosCode

Virtual-reality applications give science a new dimension

Circa 2018


Virtual- and augmented-reality tools allow researchers to view and share data as never before. But so far, they remain largely the tools of early adopters.

Be the first to comment on “Engineers Solve 50-Year-Old Puzzle in Signal Processing – Inverse Chirp Z-Transform”

Posted by in categories: computing, information science, mobile phones, virtual reality

Something called the fast Fourier transform is running on your cell phone right now. The FFT, as it is known, is a signal-processing algorithm that you use more than you realize. It is, according to the title of one research paper, “an algorithm the whole family can use.”

Alexander Stoytchev – an associate professor of electrical and computer engineering at Iowa State University who’s also affiliated with the university’s Virtual Reality Applications Center, its Human Computer Interaction graduate program and the department of computer science – says the FFT algorithm and its inverse (known as the IFFT) are at the heart of signal processing.

And, as such, “These are algorithms that made the digital revolution possible,” he said.

Facebook Plans To Make A Mind-Reading Wristband

Posted by in categories: augmented reality, computing, neuroscience, virtual reality

By this time, we can all conclude that Facebook is really ambitious when it comes to the production of high-end gadgets. This when you consider the Oculus line of devices, a VR wristband and RayBan AR glasses. And if that wasn’t enough, a new device is up for development.

The company has now revealed plans to build a mind-reading wristband letting people control devices without touching them. This is after the company finally acquired CTRL-Labs, a startup that is currently venturing into brain-computer interfaces. The deal has been reported to value at $1 billion.

The deal was then announced by Andrew Bosworth, Vice President of AR and VR at Facebook. “We spend a lot of time trying to get our technology to do what we want rather than enjoying the people around us,” he said.

Augmented reality glasses may help people with low vision better navigate their environment

Posted by in categories: augmented reality, biotech/medical, virtual reality, wearables

Nearly one in 30 Americans over the age of 40 experience low vision—significant visual impairment that can’t be corrected with glasses, contact lenses, medication or surgery.

In a new study of patients with , an inherited degenerative eye disease that results in poor , Keck School of Medicine of USC researchers found that adapted augmented reality (AR) glasses can improve patients’ mobility by 50% and grasp performance by 70%.

“Current wearable low vision technologies using are limited and can be difficult to use or require patients to undergo extensive training,” said Mark Humayun, MD, Ph.D., director of the USC Dr. Allen and Charlotte Ginsburg Institute for Biomedical Therapeutics, codirector of the USC Roski Eye Institute and University Professor of Ophthalmology at the Keck School.

Ray Kurzweil: Enhanced Longevity by 2030

People say, well, but we’re going to stop being human if we merge with machines. No, that is what it means to be human.


Dr. Kurtzweil, I would like to ask you. You have made hundreds of predictions out of which many already have come true, and with no doubt many more will come through. But if you would have to single out your three most important predictions for the upcoming decade, what would they be?
