THEMATIC APPERCEPTION TEST SYSTEM BASED ON BCI

摘要

The present invention relates to a BC eye-based psychological test and a mental disease diagnosis system using EEG, and more particularly, to present a subject to an illustration on a monitor, and at the same time, collect EEG and voice data of a subject to be used during psychological diagnosis. Voice data is quantified using Balken index method, classified into subject group according to psychological state, and statistically analyzed by frequency band and EEG-induced potential analysis of EEG data simultaneously collected during psychological examination for subject group classified by syndrome Characteristic classification is performed by classifying the subjects by feature analysis to construct a feature vector and reference value database.In the case of a practical psychological test, the EEG data of the subject and the pre-classified feature vectors and criteria are used during the psychological test using the quantitative classification results. Compare and analyze with numerical database The present invention relates to BC eye based psychological test and mental disease diagnosis system using EEG to enable the basic psychological diagnosis. BC eye-based psychological examination and mental disease diagnosis system using the present inventors, An illustration database 110 for storing and managing TAT illustration information; An illustration providing unit 120 extracting a TAT illustration from the illustration database and providing the extracted TAT illustration on a display screen; EEG data extraction unit 130 for extracting the EEG data of the subject measured by the EEG measuring unit; A voice data acquisition unit 140 for acquiring voice data of the subject; A Balken index analyzer 150 for classifying the acquired voice data into a group of subjects according to a psychological state by using a Balken index; The EEG data extracting unit 160 acquires EEG data extracted by the EEG data extracting unit and analyzes EEG data for each mental disorder (OCD, converting hysteria, anxiety state) classified using the Balken index analysis method. ; And a feature vector and a reference value database 170 for storing the feature vector and the reference numerical value for each mental disorder analyzed by the EEG data analysis unit. The present invention is presented to the subject on the monitor through the present invention. At this time, the brain wave and the voice data of the subject to be used at the time of psychological diagnosis are collected at the same time, and the voice data is quantified by using the Balken index method. , Group of subjects classified by syndrome, statistically analyze the EEG data collected at the time of psychological test by frequency band and EEG-induced potential analysis to classify the characteristics of each subject group to construct a feature vector and reference value database. In the psychological test, it is possible to provide basic psychological diagnosis by comparing and analyzing the brain wave data of the subject and the pre-classified feature vector and reference value database.
