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

Posted by in categories: biotech/medical, life extension, Ray Kurzweil, virtual reality

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?

AI Is About to Completely Change the Face of Entertainment

Posted by in categories: entertainment, robotics/AI, virtual reality

Twenty years ago, entertainment was dominated by a handful of producers and monolithic broadcasters, a near-impossible market to break into.


And now, over 50 years later, AI is bringing stories to life like we’ve never seen before.

Converging with the rise of virtual reality and colossal virtual worlds, AI has begun to create vastly detailed renderings of dead stars, generate complex supporting characters with intricate story arcs, and even bring your favorite stars—whether Marlon Brando or Amy Winehouse—back to the big screen and into a built environment.

Did we evolve to see reality as it exists? No, says cognitive psychologist Donald Hoffman

Posted by in categories: evolution, neuroscience, virtual reality

What is reality and how do we know? For many the answer is simple: What you see — hear, feel, touch, and taste — is what you get.

Your skin feels warm on a summer day because the sun exists. That apple you just tasted sweet and that left juices on your fingers, it must have existed. Our senses tell us that reality is there, and we use reason to fill in the blanks — that is, we know the sun doesn’t cease to exist at night even if we can’t see it.

But cognitive psychologist Donald Hoffman says we’re misunderstanding our relationship with objective reality. In fact, he argues that evolution has cloaked us in a perceptional virtual reality. For our own good.

Virtual reality glove system takes shape in digital realm

Posted by in categories: electronics, virtual reality

A glove focused on user experience in interacting with virtual objects is in the news. This virtual reality glove is the topic of a research article. The researchers described their virtual reality glove in detail in their paper, “Pneumatic actuator and flexible piezoelectric sensor for soft virtual reality glove system,” in Scientific Reports.

No, this is hardly the first instance of researchers able to reproduce texture but this attempt is noteworthy. As pointed out in natureasia.com, the glove system in this instance is one that allows the wearer to manipulate a virtual hand, pick up an object in virtual reality and feel its shape.
