| Interactive typeface for digital text Posted: 12 May 2021 11:35 AM PDT Researchers have developed a computer font that adapts its appearance based on the user's interaction with the text. ''AdaptiFont'' measures a user's reading speed and interactively changes the font's shape seamlessly and continuously to allow the user to read text more easily. By employing an artificial intelligence algorithm, new personalized fonts are generated on the fly in such a way that they increase an individual reader's reading speed. |
| Brain computer interface turns mental handwriting into text on screen Posted: 12 May 2021 08:56 AM PDT Researchers have, for the first time, decoded the neural signals associated with writing letters, then displayed typed versions of these letters in real time. They hope their invention could one day help people with paralysis communicate. |
| How smartphones can help detect ecological change Posted: 12 May 2021 08:56 AM PDT Mobile apps like Flora Incognita that allow automated identification of wild plants cannot only identify plant species, but also uncover large-scale ecological patterns. This opens up new perspectives for rapid detection of biodiversity changes. |
| Smaller chips open door to new RFID applications Posted: 12 May 2021 08:55 AM PDT Researchers have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies. |
| AI learns to type on a phone like humans Posted: 12 May 2021 05:34 AM PDT To really understand how people type on touchscreens, researchers have created the first artificial intelligence model that predicts how people move their eyes and fingers while typing. The AI model can simulate how a human user would type any sentence on any keyboard design. It makes errors, detects and corrects them, and also predicts how people adapt to a new auto-correction system or keyboard design. |
| Harnessing the hum of fluorescent lights for more efficient computing Posted: 12 May 2021 05:34 AM PDT The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity. |
| Tiny, wireless, injectable chips use ultrasound to monitor body processes Posted: 11 May 2021 02:41 PM PDT Researchers report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly. |
| Engine converts random jiggling of microscopic particle into stored energy Posted: 11 May 2021 01:07 PM PDT Researchers have designed a remarkably fast engine that taps into a new kind of fuel -- information. This engine converts the random jiggling of a microscopic particle into stored energy. It could lead to significant advances in the speed and cost of computers and bio-nanotechnologies. |
| Novel circuitry solves a myriad of computationally intensive problems with minimum energy Posted: 11 May 2021 01:07 PM PDT Instead of relying on software to tackle computationally intensive puzzles, researchers took an unconventional approach. They created a design for an electronic hardware system that directly replicates the architecture of many types of networks. |
| Focus on outliers creates flawed snap judgments Posted: 11 May 2021 01:07 PM PDT You enter a room and quickly scan the crowd to gain a sense of who's there - how many men versus women. How reliable is your estimate? Not very, according to new research. In an experimental study, researchers found that participants consistently erred in estimating the proportion of men and women in a group. And participants erred in a particular way: They overestimated whichever group was in the minority. |
| Online therapy effective against OCD symptoms in the young Posted: 11 May 2021 09:38 AM PDT Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited. According to a new study, internet-delivered cognitive behavioral therapy (CBT) can be as effective as conventional CBT. The study can help make treatment for OCD more widely accessible. |
