Abstract: Disclosed are a method for analyzing concentration and a device thereof capable of obtaining a bio-signal (brain wave) from a frontal lobe; and offering a current concentration state to a user through a data filtering process and a data classification process with the bio-signal. A method for detecting a frontal lobe attachment type brain wave signal and analyzing brain wave-based concentration obtains the brain wave data of the user by attaching an electrode for measuring the bio-signal of the user to the frontal lobe of the user and transmits the obtained brain wave data to a device for detecting the brain wave signal and analyzing the concentration. The device for detecting the brain wave signal and analyzing the concentration receives the brain wave data; inputs the brain wave data preprocessed through a preprocessing process performing noise removal and signal amplification to a predetermined algorithm; converts the brain wave data of time series signals into a frequency signal; and classifies the brain wave data according to the range of a converted frequency. The device for detecting the brain wave signal and analyzing the concentration detects the concentration by analyzing the classified brain wave data. After a step for detecting the concentration, a step for obtaining the brain wave data of the user is repeatedly performed because the result of the concentration detected in the step for detecting the concentration is changed in real time.

Abstract: 전두엽위치에서생체신호(뇌파)를획득하여이로부터데이터정제과정및 분류과정을거쳐사용자에게현재집중력상태를제공하는집중력분석방법및 장치를제시한다. 본발명에서제안하는전두엽부착형뇌파신호검출및 뇌파기반집중력분석방법은사용자의생체신호를측정하기위한전극을사용자의전두엽위치에부착하여사용자의뇌파데이터를획득하고, 획득된뇌파데이터를뇌파신호검출및 집중력분석을위한장치로전송한다. 뇌파신호검출및 집중력분석을위한장치는뇌파데이터를수신하여노이즈제거및 신호의증폭을수행하는전처리과정을통해전처리된뇌파데이터를기 설정된알고리즘에입력하여시계열신호의뇌파데이터를주파수신호로변환하고, 변환된주파수의대역에따라뇌파데이터를분류한다. 분류된뇌파데이터를분석하여집중력을검출한다. 집중력을검출하는과정에서검출된집중력의결과는실시간으로변하므로, 집중력을검출하는단계후, 다시사용자의뇌파데이터를획득하는단계부터반복수행한다.
