"Smartglasses Utilize AI Sonar for Gaze and Facial Expression Tracking"

Researchers at Cornell University have developed two technologies, GazeTrak and EyeEcho, that use sonar-like sensing to track a person's gaze and facial expressions. These technologies, small enough to fit on smartglasses or VR/AR headsets, consume significantly less power than similar camera-based tools. GazeTrak is the first eye-tracking system that relies on acoustic signals, while EyeEcho continuously and accurately detects facial expressions and recreates them through an avatar in real-time. The devices have applications in VR interactions, aiding people with low vision, and potentially diagnosing or monitoring neurodegenerative diseases.

"Breakthroughs in Science: Uncovering Atmospheric Holes and Advancements in Smart Glasses"

This week in science news, SpaceX rockets have been creating temporary holes in the atmosphere, known as "SpaceX auroras," by releasing fuel into the ionosphere. Smart glasses that use sonar instead of cameras have been developed, providing improved privacy and accuracy. Chinstrap penguins have been found to take 10,000 micro sleeps lasting up to four seconds each day to remain vigilant against threats. Other news includes a new "baby volcano" off Japan, a mysterious blob near the Milky Way's central black hole, and various archaeological discoveries. In health news, there are positive developments for those who have lost their sense of smell due to COVID, as well as reports of a respiratory illness in dogs.

The Dangers of Sonar Pulses: Human Injuries Underwater

Sonar pulses are used by ships to navigate and "see" underwater. The Australian navy divers sustained minor injuries, likely due to sonar pulses from a Chinese navy vessel while clearing fishing nets. Sonar can cause discomfort and health impacts to humans, such as dizziness, disorientation, temporary memory and concentration impacts, or temporary hearing loss. Marine animals, especially marine mammals, can also experience hearing damage from sonar, disrupting their critical behaviors.

Possible Positive Sign: 'Banging' Sounds Detected in Search for Missing Titan Submersible.

Banging sounds have been detected underwater near where the Titan submersible went missing while on its way to view wreckage from the Titanic. The Canadian officials on board a specialized aircraft were the ones that detected the banging underwater. The news comes as there is less than 30 hours of breathable air left. The Joint Rescue Coordination Centre is working to find an underwater remote-operated vehicle through partner organizations to possibly assist. The Titan weighs 23,000 pounds and can reach a depth of nearly 2.5 miles underwater.
