It’s just a sheet of glass. With AI.
A new paradigm for machine vision has just been demonstrated.
- Scientists have invented a way for a sheet of glass to perform neural computing.
- The glass uses light patterns to identify images without a computer or power.
- It's image recognition at the speed of light.
When we think of artificial intelligence (AI), we think of advanced computational hardware running code that allows a processor to see patterns in raw information. A team of researchers from University of Wisconsin-Madison has just published a paper in Photonics Research that describes a very different type of AI system they've invented and demonstrated. "We're using optics to condense [one might even say "replace"] the normal setup of cameras, sensors and deep neural networks into a single piece of thin glass," says senior author Zongfu Yu. While the notion of embedding some kind of AI into a simple object like glass may be head-spinningly different, their proof-of-concept demonstration shows that their smart glass can identify numbers. Their invention may provide the foundation for future artificial vision.
How it works

The system leverages the manner in which light bends, and the differences in the light reflected off of different shapes.
The scientists began by identifying the ways in which light aimed at specific shapes would bounce into and travel through their sheet of glass. (For their demonstration, they used numerical digits written on paper.) When light matches a particular shape's profile, carefully placed air bubbles and light-absorbing materials such as graphene redirect it to, and thus light up, an identifier on the far side of the glass.
To put the results of their proof-of-concept demo another way: By matching a digit's light to a known pattern, the glass intelligently identified the digit and directed it to the correct identifier. It was even smart enough to detect and correctly identify, in real time, a handwritten "3" being turned into an "8." Paper co-author Erfan Khoram marvels, "The fact that we were able to get this complex behavior with such a simple structure was really something."
That this identification occurs, after all, at the speed of light makes it a truly compelling advance. "The wave dynamics of light propagation provide a new way to perform analog artificial neural computing," says Yu.
Could this be useful? Oh, yes.
One obvious application could be image-recognition glass on the face of phones. The hardware and software currently required for facial recognition is expensive to manufacture, and it eats up scarce battery power in use. "We could potentially use the glass as a biometric lock, tuned to recognize only one person's face" according to Yu. Since the way their system works involves passive interaction with glass, he notes, "Once built, it would last forever without needing power or internet, meaning it could keep something safe for you even after thousands of years."
Concludes Yu, "We're always thinking about how we provide vision for machines in the future, and imagining application specific, mission-driven technologies. This changes almost everything about how we design machine vision."
Step inside the unlikely friendship of a former ACLU president and an ultra-conservative Supreme Court Justice.
- Former president of the ACLU Nadine Strossen and Supreme Court Justice Antonin Scalia were unlikely friends. They debated each other at events all over the world, and because of that developed a deep and rewarding friendship – despite their immense differences.
- Scalia, a famous conservative, was invited to circles that were not his "home territory", such as the ACLU, to debate his views. Here, Strossen expresses her gratitude and respect for his commitment to the exchange of ideas.
- "It's really sad that people seem to think that if you disagree with somebody on some issues you can't be mutually respectful, you can't enjoy each other's company, you can't learn from each other and grow in yourself," says Strossen.

Scientists make an important discovery for the future of computing.
- Researchers find a new state of matter called "topological superconductivity".
- The state can lead to important advancements in quantum computing.
- Utilizing special particles that emerge during this state can lead to error-free data storage and blazing calculation speed.
Erik Verlinde has been compared to Einstein for completely rethinking the nature of gravity.
- The Dutch physicist Erik Verlinde's hypothesis describes gravity as an "emergent" force not fundamental.
- The scientist thinks his ideas describe the universe better than existing models, without resorting to "dark matter".
- While some question his previous papers, Verlinde is reworking his ideas as a full-fledged theory.
As tempting as it may be to run away from emotionally-difficult situations, it's important we confront them head-on.
- Impossible-sounding things are possible in hospitals — however, there are times when we hit dead ends. In these moments, it's important to not run away, but to confront what's happening head-on.
- For a lot of us, one of the ways to give meaning to terrible moments is to see what you can learn from them.
- Sometimes certain information can "flood" us in ways that aren't helpful, and it's important to figure out what types of data you are able to take in — process — at certain times.
