(via sciencedaily.com) Original source Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published Innovations in depth from focus/defocus pave the way to more capable computer vision systems
(via sciencedaily.com) Original source In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, model-based methods fail when texture-less surfaces are present, and learning-based methods require the same camera settings during training and testing. Now, researchers have come up with an innovative strategy for depth estimation that combines the best of both the worlds to solve these limitations, extending the applicability of depth from focus/defocus.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles
(via sciencedaily.com) Original source Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published A sleeker facial recognition technology tested on Michelangelo's David
(via sciencedaily.com) Original source Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.
Published Bringing together real-world sensors and VR to improve building maintenance
(via sciencedaily.com) Original source A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Artificial intelligence helps unlock advances in wireless communications
(via sciencedaily.com) Original source A new wave of communication technology is quickly approaching and researchers are now investigating ways to configure next-generation mobile networks.
Published AI discovers that not every fingerprint is unique
(via sciencedaily.com) Original source Engineers have built a new AI that shatters a long-held belief in forensics -- that fingerprints from different fingers of the same person are unique. It turns out they are similar, only we've been comparing fingerprints the wrong way!
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Non-toxic quantum dots pave the way towards CMOS shortwave infrared image sensors for consumer electronics
(via sciencedaily.com) Original source Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.

(via sciencedaily.com) Original source Engineers developed a technology that delivers centimeter-level accuracy for real-time tracking in extended reality (XR) applications. It uses wireless signals to ensure precise asset localization and smooth tracking, promising to enhance virtual gaming experiences and workplace safety.
Published 360-degree head-up display view could warn drivers of road obstacles in real time
(via sciencedaily.com) Original source Researchers have developed an augmented reality head-up display that could improve road safety by displaying potential hazards as high-resolution three-dimensional holograms directly in a driver's field of vision in real time.
Published Could an electric nudge to the head help your doctor operate a surgical robot?
(via sciencedaily.com) Original source People who received gentle electric currents on the back of their heads learned to maneuver a robotic surgery tool in virtual reality and then in a real setting much more easily than people who didn't receive those nudges, a new study shows.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com) Original source Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Immersive VR goggles for mice unlock new potential for brain science
(via sciencedaily.com) Original source New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published Scientists propose a model to predict personal learning performance for virtual reality-based safety training
(via sciencedaily.com) Original source In Korea, workers are being provided with virtual reality (VR)-based safety training content to mitigate the increase in occupational accidents.
