Surya Yadav

You don’t need rocket science to understand that the digital world is getting more advanced day by day. Imagine a technology where you can control a machine or computer with your thoughts. In this case, we have to mention Ai eeg by BrainAccess. Yes, there are some outstanding companies that are working on Brain Computer Interface systems. 

As research is getting advanced day by day, there are so many possibilities in the future. On the other hand, this technology is designed to improve skills related to brain activities. Well, all of these things can be confusing for you. That’s why we will cover everything you have to know about the BCI system. So, let’s get started.

About Brain Computer Interface System

In simple words, the BCI system is designed to quantify and detect brain signals to read users’ intentions. After that, the system will translate the features to the device’s real-time command. In this case, the system works with four sequential components. Let’s find out about them:

  • Signal Acquisition

It’s a procedure to measure analog signals from the brain using different sensors. The received signals are filtered to remove noise from the signal. Next, the signals will be digitalized by using a digital converter.

  • Feature Extraction

Next, feature extraction is a crucial process that helps extract the unique features of the received brain signals. Well, these features have strong correlations with the user’s intent. 

  • Feature Translation

After the feature is extracted, it will pass through the feature translation algorithm. The key task of this process is to convert the received signals to commands to the BCI output device.

  • Device Output

The feature translation unit will be provided to a specific output device. Well, the feature operates the external device providing various functions.

Now, you have a clear idea about how the Brain Computer Interface system works. Read more here to get everything cleared. It can be challenging to understand everything, but you can learn the technology with proper research. 

Types of BCI System

The best part is there are different types of BCI systems available. All of these machines are designed for doing different things. Let’s find out about the best BCI systems in the following section:

Invasive BCIsThis is the most popular one. The key advantage of using invasive BCIs is they provide an accurate reading. However, it has some cons as brain signals can be weaker. Plus, some researchers said that implanting electrodes causes some medical complications as well.

Semi-Invasive BCIsThe semi-invasive BCI device can be implanted inside the skull. In this case, this technology provides better results as compared to non-invasive BCIs. Plus, it provides more accurate signals as well. Unlike invasive BCIs, semi-invasive BCIs have a lower risk of scar tissue forming.

Non-invasive BCIsAs the name suggests, a non-invasive BCI device doesn’t need to be implanted in the skull. Sure, most non-invasive BCIs rely on electrodes because they are placed on the area of the scalp to record brain activities. 

Brain Computer Interface System Application

Many people have some misconceptions about the BCI system. However, it’s not limited to the medical field. The application for the BCI system is spread in diverse fields including education, gaming, entertainment, advertisement, and more. As technologies are getting advanced, we can witness more from this system in the future. 

When we are talking about the BCI system, we have to mention its significance in the medical field. There are some crucial disorders such as epilepsy, brain state during sleep, and sleep disorders that can be detected and diagnosed by this system. 

Besides the medical field, this system is getting popular for making smart environments that can be helpful for transportation, workplaces, and smart houses. In fact, BCI technology is getting popular in the marketing world. Simply put, the possibilities of this system are too good.


Finally, you have an idea about the Brain Computer Interface System. You see, this technology will get more advanced with time. As we are discovering this technology, there are so many things to explore. If you want to know more, you can do your research. In fact, you can also get help from an expert.
