Improving touch screens with AI

Posted by in categories: mobile phones, robotics/AI

ETH Computer scientists have developed a new AI solution that enables touchscreens to sense with eight times higher resolution than current devices. Thanks to AI, their solution can infer much more precisely where fingers touch the screen.

Quickly typing a message on a smartphone sometimes results in hitting the wrong letters on the small keyboard or on other input buttons in an app. The touch that detect finger input on the have not changed much since they were first released in mobile phones in the mid-2000s.

Mind over matter: brain chip allows paralysed man to write

Posted by in categories: computing, mobile phones, neuroscience

Tokyo (AFP)

Paralysed from the neck down, the man stares intently at a screen. As he imagines handwriting letters, they appear before him as typed text thanks to a new brain implant.

The 65-year-old is “typing” at a speed similar to his peers tapping on a smartphone, using a device that could one day help paralysed people communicate quickly and easily.

Singapore researchers control Venus flytraps using smartphones

Posted by in categories: mobile phones, robotics/AI, space

Researchers in Singapore have found a way of controlling a Venus flytrap using electric signals from a smartphone, an innovation they hope will have a range of uses from robotics to employing the plants as environmental sensors.

Luo Yifei, a researcher at Singapore’s Nanyang Technological University (NTU), showed in a demonstration how a signal from a smartphone app sent to tiny electrodes attached to the plant could make its trap close as it does when catching a fly.

“Plants are like humans, they generate electric signals, like the ECG (electrocardiogram) from our hearts,” said Luo, who works at NTU’s School of Materials Science and Engineering.

Faster, More Secure Memory Storage: Physicists Find a Novel Way to Switch Antiferromagnetism On and Off

Posted by in categories: computing, mobile phones, physics, security

The findings could lead to faster, more secure memory storage, in the form of antiferromagnetic bits.

When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of “bits” to represent and encode that image. Most transistors today are made from silicon, an element that scientists have managed to switch at ever-smaller scales, enabling billions of bits, and therefore large libraries of images and other files, to be packed onto a single memory chip.

But growing demand for data, and the means to store them, is driving scientists to search beyond silicon for materials that can push memory devices to higher densities, speeds, and security.

IBM unveils 2-nanometer chip technology for faster computing

Posted by in categories: business, computing, mobile phones

The pace of those improvements has slowed, but International Business Machines Corp on Thursday said that silicon has at least one more generational advance in store.

IBM introduced what it says is the world’s first 2-nanometer chipmaking technology. The technology could be as much as 45% faster than the mainstream 7-nanometer chips in many of today’s laptops and phones and up to 75% more power efficient, the company said.

Nano flashlight enables new applications of light

Posted by in categories: mobile phones, nanotechnology

In work that could someday turn cell phones into sensors capable of detecting viruses and other minuscule objects, MIT researchers have built a powerful nanoscale flashlight on a chip.

Their approach to designing the tiny light beam on a chip could also be used to create a variety of other nano flashlights with different beam characteristics for different applications. Think of a wide spotlight versus a beam of light focused on a single point.

For many decades, scientists have used light to identify a material by observing how that light interacts with the material. They do so by essentially shining a beam of light on the material, then analyzing that light after it passes through the material. Because all materials interact with light differently, an analysis of the light that passes through the material provides a kind of “fingerprint” for that material. Imagine doing this for several colors — i.e., several wavelengths of light — and capturing the interaction of light with the material for each color. That would lead to a fingerprint that is even more detailed.
