Chinese developers unveil brain-computer interface for typing text with thoughts

Chinese engineers have presented a device that allows users to create text messages using thought alone. The development works by reading brain signals and demonstrates a 94% accuracy rate. This brain-computer interface does not require craniotomy or the installation of implants.

Operating principle and user comfort

At the heart of the technology is a special headband equipped with new electrodes. The device records the brain's electrical activity when the user focuses their attention on an image of a virtual keyboard.

Signal stability and autonomy

The new electrodes ensure stable signal transmission for over eight hours of continuous use. This allows testers to walk, eat, and engage in routine activities without removing the device.
