Scientists have succeeded in a wonderful experiment. This is called brain computer interface. This means that whatever you think in the mind, even if you remain silent, the computer will understand it immediately. Then the cracker will give necessary orders to fulfill your wish. This technique is being described as a major success for the communication of paralyzed people.
This technique directly acts as a bridge between your brain and computer. That is, whatever you are thinking in the mind, it will be recorded immediately on the computer. A recent study of the University of Stanford decoded a person’s ideas directly on a computer without any gesture or voice. In this technique, electrodes are placed in the person’s head. Subsequently, whatever happens in the brain, these electrodes start recording it and through the computer, understand those things and tell it. This technique is very useful for disabled people. Especially for those who cannot write or say their words.
Scientists recorded signs on shaking mouth, tongue, lips and vocal in the motor cortex of the brain of people unable to speak earlier. Then used to turn them into voice. But now a new study of Stanford University has sidelined the voice of the body. He has shown that work can be done easily even without it.
What is a brain-computer interface?
Brain Computer Interface or BCI is a technique in which computer directly understands your brain activity. Changes it into action. Our brain is made up of nerve cells or neurons, which communicate with each other through electrical signals. When we think of something, a pattern of these signs is formed in our brain. The BCI catchs these signs and analyzes them and then orders the computer. The computer starts recording them.
Imagine that you are sitting in your room and want to turn on the TV, but you cannot use your hands or voice. In this way, BCI will understand your mind that you want to turn on the TV. Then the computer will understand that order and turn on the TV.
How does this technique work?
For this, small electrodes are placed on the head. These electrodes catch the electrical activity of the brain. The most common method is EEG or Electro Ensafelography, with sensors in a cap like hat. The signs obtained from the brain are very complex and brief. Therefore, computer programs are used to convert them into clear and useful signals. These programs try to understand your way of thinking. This command starts generation work. In this, the computer converts the processed signal into a command. For example, if your brain sends a sign of turning on the TV, the computer turns that signal to the command of ‘TV turn’. The computer then executes that command on your home smart device, robot, computer or mobile phone. You will be without whatever you want, without hands, feet or voice.
Is this technique still used?
Yes, this is a very fast emerging technique. It is not yet fully available to the general public, but many research labs and companies around the world are developing it. This technique is proving revolutionary especially for those whose hands and feet do not work. It opens a new world for them, where they can run computers, wheelchairs, robotic arms and mobile devices only with their ideas.
Elon Musk’s company is working on it
Neuralink is one such company of Elon Musk, which is trying to take BCI to a new level. Their plans are to grab signals directly into the brain through small chips, so that highly accurate orders can be given. Brain-computer interfaces are being used in many hospitals to treat paralysis, motion disorders or patients suffering from other neurological diseases.
This technique will be even easier in future
In the future, we can see that this technique will become even more convenient. We will be able to control our smartphones, TV, robot, car, air conditioner etc. with our ideas only. Through this technique, areas such as making the lives of disabled people easier, giving voice to deaf and mental health will develop areas such as improvement and improvement in mental health.
But it is also dangerous
This technique is very beneficial, but some challenges are also associated with it. Since your thoughts reach the computer directly, your privacy may be in danger. Understanding brain waves correctly is still a big challenge.
This is a technical challenge. Wrong commands can also arise on the wrong signal.
If these chips are used for a long time without caution, it can also affect health.
Well, researchers from Stanford have developed a password-security system that prevents the technique from decoding a person’s internal voice until he thinks the first password.
