Wearable Brain-Machine Interface Turns Intentions into Actions - ELE Times

#artificialintelligence

A multi-institutional, international team of researchers at the Georgia Institute of Technology combined wireless soft scalp electronics and virtual reality in a BMI system that allows the user to imagine an action and wirelessly control a wheelchair or robotic arm. The major advantage of this system to the user, compared to what currently exists, is that it is soft and comfortable to wear, and doesn't have any wires. BMI systems are a rehabilitation technology that analyzes a person's brain signals and translates that neural activity into commands, turning intentions into actions. The most common non-invasive method for acquiring those signals is ElectroEncephaloGraphy, EEG, which typically requires a cumbersome electrode skull cap and a tangled web of wires. These devices generally rely heavily on gels and pastes to help maintain skin contact, require extensive set-up times, are generally inconvenient and uncomfortable to use.

A Novel Visualization System of Using Augmented Reality in Knee Replacement Surgery: Enhanced Bidirectional Maximum Correntropy Algorithm

arXiv.org Artificial Intelligence

Background and aim: Image registration and alignment are the main limitations of augmented reality-based knee replacement surgery. This research aims to decrease the registration error, eliminate outcomes that are trapped in local minima to improve the alignment problems, handle the occlusion, and maximize the overlapping parts. Methodology: markerless image registration method was used for Augmented reality-based knee replacement surgery to guide and visualize the surgical operation. While weight least square algorithm was used to enhance stereo camera-based tracking by filling border occlusion in right to left direction and non-border occlusion from left to right direction. Results: This study has improved video precision to 0.57 mm~0.61 mm alignment error. Furthermore, with the use of bidirectional points, for example, forwards and backwards directional cloud point, the iteration on image registration was decreased. This has led to improve the processing time as well. The processing time of video frames was improved to 7.4~11.74 fps. Conclusions: It seems clear that this proposed system has focused on overcoming the misalignment difficulty caused by movement of patient and enhancing the AR visualization during knee replacement surgery. The proposed system was reliable and favorable which helps in eliminating alignment error by ascertaining the optimal rigid transformation between two cloud points and removing the outliers and non-Gaussian noise. The proposed augmented reality system helps in accurate visualization and navigation of anatomy of knee such as femur, tibia, cartilage, blood vessels, etc.


CES 2021 Innovation Awards: Winners and trends

ZDNet

Each year, CES runs an extensive programme of innovation awards, calling out a subset of the thousands of products on show for excellence in engineering, aesthetics and design, uniqueness, the innovation they bring to the consumer market, and more. There are two levels of recognition: 'Honorees' are products that score above the threshold for a given category, while'Best of Innovation' is reserved for the highest-rated product(s) in each category (see the CES website for more details on the judging process and expert panel). As usual, there's a diverse range of products on view, from the mainstream (AMD's Ryzen 5000 desktop processors, Samsung's Galaxy Note 20 smartphones, for example) to the highly specialised (E2IP Technologies' Electromagnetic Engineered Surfaces that reflect/redirect/block specific radiofrequency waves, John Deere's X-Series robotic combine harvester, for example). The latter uses voxel-based graphics rendering to capture a person's physical appearance, convert it to digital and create live 3D holograms viewable with VR/AR headsets. Use cases include remote collaboration, gaming, telehealth, online education and live entertainment.


Man builds a bionic hand using AI after three years of research

Daily Mail - Science & tech

A Texan man has built his own bionic hand using artificial intelligence (AI) after three years of research. After finding most bionic hands can cost up to $150,000, Ryan Saavedra, 27, set out to create one at a fraction of the cost. The prosthetic he created, called the Globally Available Robotic Arm (GARA), measures electrical activity of muscle tissue – a method called electromyography (EMG) – and combines this with AI to predict hand movements. When attached to the limb of an amputee, it is capable of intuitive finger movements and clasping objects such as cups. Saavedra's company, Alt-Bionics, has already made a prototype that costs less than $700 (£520) to produce, and is now working to commercialise the device.


Healthtech Has Blossomed in Vietnam … the future is now

#artificialintelligence

Vietnam's response to COVID-19 is a perfect example of how a country with modest financial means can successfully address a grave health challenge. At the end of Vietnam's first pandemic wave, Politico, the US-based political news organization ranked Vietnam the world's best performer. Many in Vietnam have now begun to focus on the technology that will create better healthcare. Some of this is no doubt driven by the focus that COVID-19 has put on Vietnam's healthcare deficiencies, and on worldwide innovation in the delivery of solid healthcare. The case for augmented healthcare solutions has been growing, leveraging the use of artificial intelligence ("AI"), blockchain technology, virtual reality/augmented reality ("VR/AR"), 3D printing, and robotic applications.

Want to Decode the Human Brain? There's a New System for That, and It's Pretty Wild

#artificialintelligence

Even for high-tech California, the man strolling around UCLA was a curious sight. His motion capture suit, sensor-embedded gloves, and virtual reality eyewear were already enough to turn heads. But what stopped people in their tracks and made them stare was a bizarre headgear, tightly strapped to his head through a swimming cap-like device embedded with circular electrode connectors. Several springy wires sprouted from the headgear--picture a portable hard drive hooked up to a police siren enclosure--and disappeared into a backpack. Meet Mo-DBRS, a setup that could fundamentally change how we decode the human brain.


Scientists develop a real-life 'cyclops lens' with a laser pointer

Daily Mail - Science & tech

Scientists have taken inspiration from X-Men's Cyclops and created a contact lens that points a red laser at what the wearer is looking at. The regular-size contact lens is fitted with a vertical cavity surface emitting laser (VCSEL) which points in the direction the user is looking. French engineers used off-the-shelf components to create a working prototype which can be used for gaze recognition. Gaze recognition is a budding field of research and could be the next frontier for computer systems. Instead of using a touch screen or a mouse to control a device, gaze recognition would allow users to select options on a display just by looking at them.
