Keyboard for decades been a reliable helper to enter information in computer. Studies conducted by scientists from Princeton University (USA), under favorable circumstances can change things . A team of university scientists found a way to match a person's thoughts .
Scientists gave the volunteers a picture of some real object (for example - at home, or a tree) and took pictures MRI (Magnetic Resonance Imaging) of their brain. Pictures differed from one to other, the closer the subject area , the smaller was the difference in brain activity displayed in the pictures. Images of hands and eyes (of human body parts) caused significantly less change than the image of arms.
Although these studies are at an early enough stage, and scientists will have to teach a computer to recognize images of brain activity when dealing with abstract concepts, actions, and many others, over time they can become the base of devices designed to capture human thought. They can be used in speech device for completely paralyzed, or as core module of niversal translator.
