The development, called sEMG-RD, uses the skin surface on the wrist to record electrical signals transmitted from the brain to the muscles. Thanks to sensitive sensors and a trained neural network, the bracelet accurately interprets commands. No individual calibration is required — the system works out of the box, relying on an extensive database collected from thousands of participants. sEMG-RD allows you to control the interface with gestures, including finger squeezes, thumb taps, and even writing in the air at speeds of up to 21 words per minute. This is almost comparable to the average typing speed on a phone.

The device can greatly simplify the use of technology for people with limited mobility or muscle weakness, as well as open up new, more natural ways of interacting with digital devices.

The device is not yet available for sale, but the developers are confident that it will find application in a wide variety of areas, from AR/VR to everyday tasks
