What is BCI?
Brain-computer interface (BCI) is a new technology that allows people to control devices using only their minds. A special headset picks up brain signals and sends them to a computer, in order to control a device. The main advantage is that BCI does not rely on physical movements. This makes BCI a unique assistive technology for people who have no other way to control devices. Many kinds of devices can be used with BCI, such as video games, robots, remote-controlled cars, smart home technology, and even power wheelchairs.
How Does it Work?
BCIs detect signals coming from the brain, and then process them to decide what the user is intending to do. The BCI unit is a headset that sits on the user’s head and monitors brain activity. With guidance from a therapist, the user learns how to think in a certain way. A computer learns to recognize the brain activity patterns. Once the computer has a good idea what the intent is, then it can tell the device what to do.
