Published Building a better sarcasm detector
(via sciencedaily.com) Original source Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools. So researchers have now developed a multimodal algorithm for improved sarcasm detection that examines multiple aspects of audio recordings for increased accuracy. They used two complementary approaches -- sentiment analysis using text and emotion recognition using audio -- for a more complete picture.
Published First 'warm-blooded' dinosaurs may have emerged 180 million years ago
(via sciencedaily.com) Original source The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com) Original source Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be
(via sciencedaily.com) Original source New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Biomechanical dataset for badminton performance analysis
(via sciencedaily.com) Original source In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
Published Unveiling a polarized world -- in a single shot
(via sciencedaily.com) Original source Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
Published Feathers, cognition and global consumerism in colonial Amazonia
(via sciencedaily.com) Original source Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.
Published Virtual reality environment for teens may offer an accessible, affordable way to reduce stress
(via sciencedaily.com) Original source Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.
Published Researchers develop a new way to instruct dance in Virtual Reality
(via sciencedaily.com) Original source Virtual reality dance made easier with crowd wave technique. Open source code can be downloaded for Quest 2 and 3.
Published Holographic displays offer a glimpse into an immersive future
(via sciencedaily.com) Original source Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Published Child pedestrians, self-driving vehicles: What's the safest scenario for crossing the road?
(via sciencedaily.com) Original source Crossing roads for children can be a risky calculation, especially when the vehicles are self-driven. In a new study, researchers determined pre-teenage children are safest when self-driving vehicles signaled their intent to yield with a green light when they arrived at the intersection, then stopped.
Published Teaching a computer to type like a human
(via sciencedaily.com) Original source A new typing model simulates the typing process instead of just predicting words.
Published Mountain chickadees have remarkable memories. A new study explains why
(via sciencedaily.com) Original source Mountain chickadees have among the best spatial memory in the animal kingdom. New research identifies the genes at play and offers insight into how a shifting climate may impact the evolution of this unique skill.
Published Star Trek's Holodeck recreated using ChatGPT and video game assets
(via sciencedaily.com) Original source Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Published Waterproof 'e-glove' could help scuba divers communicate
(via sciencedaily.com) Original source When scuba divers need to say 'I'm okay' or 'Shark!' to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see. Now, researchers have constructed a waterproof 'e-glove' that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface.
Published Birdfeeders are designed to keep unwanted guests away
(via sciencedaily.com) Original source The first birdfeeders were made in the 19th century, and their design rapidly evolved during the 20th century. Researchers at the consider the evolution of the birdfeeder to be an example of multispecies design, where unwanted guests have shaped the human-made artifact.
Published Dinosaur study challenges Bergmann's rule
(via sciencedaily.com) Original source A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.
Published Early dinosaurs grew up fast, but they weren't the only ones
(via sciencedaily.com) Original source The earliest dinosaurs had rapid growth rates, but so did many of the other animals living alongside them, according to a new study.
Published We've had bird evolution all wrong
(via sciencedaily.com) Original source Genomic anamolies dating back to the time of the dinosaurs misled scientists about the evolutionary history of birds.
