This Bracelet from Meta Translates Hand Movements into Computer Actions

Meta’s Neuromotor Interface – credit, Reality Labs, via Springer PressA very sci-fi invention has been introduced by engineers from Facebook’s parent company that translates hand gestures into computer actions.This includes fine motor movements like dotting a lowercase i, and translating handwriting into computer text is something the interface is particularly good at.Designed inside Meta’s Reality Labs, it’s one of the first major offerings from the in-house moonshot department since the collapse of the company’s “Metaverse” concept which was once expected to “define the future of social connection” according to CEO Mark Zuckerberg, who renamed his company in its honor.The Metaverse ended up being less of a future-defining technology and more like a damp squib, with the Reality Labs division of Meta losing $14 billion in 2022 and $15 billion in 2023.Reality Labs was on the chopping block during Meta’s Year of Efficiency, with perhaps as many as 10,000 layoffs taking place in advance of a direction shift to what almost anyone would admit is a more exciting and marketable business direction: stuff that looks like it’s from Star Trek.The device can translate the electrical signals generated by muscle movements at the wrist into computer commands without the need for personalized calibration or invasive procedures.

This Wearable Device Monitors Health by Sensing the Gases Passing Through Your Skin

Credit: John A. Rogers / Northwestern University.Your skin is breathing. This wearable gas sensor can measure it.Northwestern University researchers have developed the first wearable device for measuring gases emitted from and absorbed by the skin.By analyzing these gases, the device offers an entirely new way to assess skin health, including monitoring wounds, detecting skin infections, tracking hydration levels, quantifying exposure to harmful environmental chemicals and more.The new technology comprises a collection of sensors that precisely measure changes in temperature, water vapor, carbon dioxide (CO2) and volatile organic compounds (VOCs), which each give valuable insight into various skin conditions and overall health. These gases flow into a small chamber within the device that hovers above the skin without actually touching it. This no-contact design is particularly useful for gathering information about fragile skin without disturbing delicate tissues.“This device is a natural evolution of our lab’s wearable electronic devices that collect and analyze sweat,” said Northwestern’s John A. Rogers, who co-led the study. “In that case, we were analyzing sweat to learn about the wearer’s overall health. While useful, that method requires pharmacological stimulation of sweat glands or exposure to a hot, humid environment. We...
