Direct brain interfaces are devices that allow technology to communicate directly with the brain. Think of it like a translator between technology and your brain! These types of interfaces are designed to help people who have disabilities or injuries that prevent them from using traditional methods, like a keyboard or mouse, to communicate with technology.
The device is placed onto the scalp and uses electrodes to measure the electrical activity of the brain. This information is then sent to a computer, which analyzes it and takes action based on the user's thoughts. For example, a person could use their thoughts to move a cursor on a computer screen or control a robotic arm.
It's important to note that direct brain interfaces are still in the early stages of development and are not widely available for everyday use. However, researchers are working hard to improve the technology and make it more accessible to a larger number of people in need.
