Final answer:
Smart technology, such as brain-computer interface (BCI), is used to assist people with disabilities by allowing them to control computer and other tools with their thoughts.
Step-by-step explanation:
Smart technology is being used to help people with disabilities in various ways. One notable application is brain-computer interface (BCI) technology, which allows paralyzed patients to control a computer or other tools using their thoughts. BCI technology can be used to help people communicate, interact with their environment, and perform daily tasks, even if they have limited physical mobility. For example, BCI technology has enabled paralyzed patients to use email, navigate the internet, and control a robotic arm.
