Application Possibilities of the BCI Tools in Justice

Abstract

The wording “brain-computer interface” was used first in the 1970’s by Jacques Vidal, to describe any system whose function is to give us a detailed information of the brain activities. The brain-computer interface (BCI) provides direct communication channel between the human brain and the computer using electro-enchephalograpy (EEG), which helps today in practice in communication and movement to persons with disabilities. BCIs are appeared in many other territories, such as: medicine, military, security, transport, data processing and even education. Studying and researching the brain waves had begun on the end of the XIX. century. In the last more than 100 years, many attributes of the brainwaves has been obtained. Including the so-calle. P300 wave, whose role is still unknown, but researches have shown that it is triggered when the observed person finds himself in familiar situation. On that basis, the P300 signal is suitable to control brain’s cognitive functions in clinical situations when it is not possible in other ways. In addition, it can be used to construct BCI devices which can help users to enter characters into the computer. Over the last decade, there are researches published which are examining the applicability of the BCI in the justice system. The most effective application in that area of them is lie detection.
