METHOD AND APPARATUS FOR BRAINWAVE DETECTION DEVICE ATTACHED ONTO FRONTAL LOBE AND CONCENTRATION ANALYSIS METHOD BASED ON BRAINWAVE

摘要

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.
