The brain-computer interface(BCI) is also called the brain-machine interface(BMI). It is a technology that allows the brain and computer and other digital devices to communicate. Brain-computer interface (BCI or BMI) is very helpful for people disabled by a neuromuscular disorder.

When sense organs communicate with the brain we feel the real world. But when computers will start to communicate with the brain we will also feel the virtual world.[READ MORE]

How is it possible?

There are a number of companies trying to develop this technology. The brain signal can be measured invasively or non-invasively. In case of invasive, an electrode is placed within or on the surface of the cortex (the part of the brain responsible for perception, sensation, memory thought, voluntary action, etc ). And in the case of the non-invasive, electrical signal is measured from the surface of the scalp. Some of the companies working on this technology are Neuralink, Neurable, Emotiv, Nextmind, etc.

According to a company called “Neuralink” very thin, micron-scaled threads are inserted into the areas of the brain that control movement. These threads contain a large number of electrodes to detect neural signals.

The thread is connected to the link. Link is a sealed implanted device that processes stimulates and transmits neural signals outside the brain for action.

Why do we need such a technology?

This is the ultimate question. If companies are investing a huge amount of money then there must be some goal to achieve.

BMI has applications in the field of healthcare, entertainment, virtual reality, education, self-driving cars. IN the field of healthcare this technology will enable a paralyzed person to walk and move. Dumb people will be able to communicate with others. A paralyzed person will be able to work on a computer (typing, internet browsing) just by thinking.

Other applications may be in the field of entertainment. We will realize virtual reality. People will feel the scenes of movies. They will get the feeling of the existence of the same environment around them as it will in the movie.

The other reason might be competition with machines. As machines are evolving very fast. Some scientists, entrepreneurs think that someday technologies like AI, robotics can become very powerful. In that case, humans should also have the capability to compete with them either they may enslave us.
