A brain-computer interface (BCI)

A brain-computer interface (BCI) is a system that records brain activity and translates it into a signal that can be used to control a computer or other devices.

BCI systems are used by people with paralysis or other conditions that prevent them from using conventional input devices. BCIs bypass damaged nerves and muscles to allow direct communication between the brain and the device.

BCIs are still in the early stages of development, and most are experimental. Current BCI systems can only control basic functions, such as moving a cursor or opening and closing a prosthetic hand.

Despite these limitations, BCIs hold great promise for people with disabilities. In the future, BCIs may be used to restore lost abilities, such as the ability to walk or talk.

There are also potential risks associated with BCIs. For example, BCIs could be used to hack into devices or steal sensitive information. In addition, BCIs could be used to control people against their will.

To avoid these risks, it is important to carefully consider the security and privacy implications of BCIs before they are deployed.
