New Delhi, July 24 -- For many years, people have found new ways to interact with computers. Now, Meta is developing a wristband that allows users to control devices by reading muscle signals from the wrist. This new technology uses subtle hand movements to operate computers without the need for keyboards, mice, or screens, making interaction more natural and easier.

Meta's Reality Labs has been studying a technology called surface electromyography, or sEMG. This method measures tiny electrical signals produced by muscles in the wrist when the user moves their hand. By detecting these signals, computers can understand gestures such as tapping, swiping, and pinching. The system works without bulky equipment and does not require invasive s...
