Brain-Computer Interface | How Can Computers be Controlled by Human Brains?

If you are asked to think about future technologies, what kind of imagination will you have in mind? — Changing tv channels without doing anything or changing the remote? Playing computer games with command with mind? Or play games directly in the head without playing games on the monitor? Going into the world of computer games? What’s the mind of a man? Your imagination is on the computer screen? — All these ideas are crazy but brain-computer interfaces can make things all busy with brain-computer interfaces.

Modern computers are improving day by day, and they are trying to understand the human brain more. And that’s what makes our imagination’s science fiction so busy. In this article, let’s start with how BCI works and discuss the potential of this technology.

Electric Signal of the Brain


Why do we compare human brains and computers and connect to each other? See the computer is an electronics division made of plastics, transistors, Ics, etc., but the human brain is a living thing; Each nerve cell is connected to each other by Dendrites and Axon, which is composed of a number of small cells of about 100 billion.

It is obvious that computers and brains are completely different structures. But the brain’s working style is like a computer. Neuron works work when we talk, work, think, or do anything — to accomplish it. And during this work, the neuron creates a kind of electrical signal and is shared from the neuron to the neuron. And you know, electronics also work on electric signals. Based on this electric signal, the brain can be connected to the computer or to the brain.

Artificial neural networks and mind uploading technology work on this idea. However, the electrical signal that is produced in the brain is able to be reed by scientists, meaning that the different types of signals that are produced in our brain during different tasks, scientists can capture the signal and understand what is produced for the purpose. For example, if you see red or green in front of your eyes, the optic nerve from your eyes will send a kind of electrical signal to the brain. And the signal is zipped in the information, your eyes see exactly which color.

Now if you can read that signal and send the same signal directly from the camera to the brain, your brain will see the same color, thus making the signal with the camera and turning the blind person’s attention back. No matter how bad the blind’s eyes are, their ability to recognize the signal of the brain is not lost.

Brain-computer Interface


Demo Brain Computer InterfaceYou can call the brain-computer interface a direct connection to the computer and the human brain. This is the latest development of human computer interface. Mouse, keyboard or other input divisions are used to provide some input on the computer, but the BCI can provide input directly from the brain to the computer. You don’t have to write anything, just bring it to mind, and the screen will be all typed, even the mouse cursor you can move through the brain.

BCI’s potential and applications are thousands. Everything possible between people and computers can be done by improving this technology. Think about Next Generation Gaming, where gaming doesn’t have to be held on a keyboard or console. The head may have a wireless chip attached, and it will be connected directly to the computer, the direct brain will be able to control the game.

Think again about disabled patients who cannot hear or see. They can be shown and heard by creating electric signals from live cameras and mics to the brain –what could be a bigger discovery than this in the human computer interface? Moreover, BCI will provide more details about brain activity and neural networks, which will enable further improvement and accuracy in the artificial neural network and mind uploading technology. —No, we can make the human brain as much as we know it, making the computer as much as possible.

Think about social media where you can post your feelings, memories, feelings and feelings with photos after uploading photos and feel like you. This is how we begin to understand the brain and improve the application. The BCI application system works by accounting for the entire brain’s function. Below is a discussion on the input and output of the BCI;

BCI Input/Output


How BCI WorkThe basic idea of making this technology work properly has put the researchers in a lot of trouble, not because our brain is so simple, it has a billion neurons and millions of signals are being generated all the time. Human brains work in the most complex way. To read the signal from the brain, you must have something in your head that captures the signals and sends them to the computer.

Electrodes are used for this purpose, which is called electroencephalograph; And it needs to be attached to the scalp. Electrodes can read electrical signals in the brain but the problem is that the brain receives a lot of weak signals and most of the signals are blocked by the skull.

So to get better signal quality, the researchers can plant electrodes directly on the scalp and install electrodes directly into the brain’s surface to provide better signal quality than before. However, the top floor of the skull is not four words of electrodes, it requires extensive surgery. Once successfully performed surgery, the electrodes start to capture the electrical signal from the brain, since the signals are too weak to filter and apply signals to work properly.

These electric signals are saved by a computer program, which looks like an audio wave form. First, the brain is re-read the signal for a function and then the reverse signal from the BCI program on the computer is generated and then applied to the neuron of the brain. For example, if your eyes are seeing some objects, it is sure to be a signal reaching the brain, if you can use the same signal to plant the neuron after taking a picture from the camera, then the brain will be able to see it, the brain will create visual images.

Application of Brain-computer Interface (BCI)


I said before, the possibility of BCI is not over. You can be busy with many things you can imagine. However, reading a lot of articles on this issue, I found that this technology is being developed primarily to help the disabled, though there is much more to be done. Yet there is nothing more noble than that.

Using cameras can restore the blind’s eyesight. This technology will also bring blessings to those who have lost their hands or feet since birth or due to various accidents. They can be applied to robotic hands, which will work by receiving signals from the brain, but those who are assigned robotic organs will need exercise to do the right thing. Also, it’s possible to move a computer cursor by thinking of moving a subject in the brain, everything will be mind control. Also, if you can read the brain in more detail, you may also type something using your mind, and you can change the TV channel without doing anything. Note that once all processes are done properly, there will be no limit to the potential for brain-computer interfaces.

How Far Away Are We From BCI?


So far, the most important question is, the brain-computer interface has understood all the basics; How late is the brain-computer interface still from the technology in front of our eyes? Look, the brain-computer interface is no longer a science fiction, it’s a living science! But BCI has not yet been able to perfect. Look, our brain is not that simple, our brain is more complex than any complex machine in the world; It contains billions of neurons that are constantly receiving and receiving electric signals from each other, and electrodes have not been able to capture the signal so finely.

Besides, not only electric signals in the brain but also chemical reactions and that cannot be captured by electrodes. Also, there are a lot of weak signals coming from the brain that capture is like standing ten feet away from the fish market and talking to someone. And the biggest problem is that the brain-computer interface still uses wires, with the size of the computers as giant, if portable and wireless technology can be combined here, the technology will only be developed. But I’m sure we can.

Last words


I don’t want to end it with something so extraordinary. Yet, the article is too long to finish. So what do you think about such a great technology? What is the possibility? Can it be improved at all? – Let us comment below.
