How does a brain computer interface work?
• The brain produces millions of tiny electrical pulses every millisecond. • Electrodes placed on a person’s scalp can record this activity and transmit it to a computer. • Sophisticated software then processes the signals and translates them into a command. • The goal is usually for the person to attempt to influence an object on a computer screen by performing some sort of mental task. • Different BCI systems use different tasks, the ISRC system involves a person imagining moving either their left or right arm. • The system detects the brain waves associated with the imaginary left or right arm movement and moves the object on screen accordingly.
