Analysis of Brain Wave Pattern among Different Individuals

Abstract

This paper presents the outcomes of a research that investigates human brainwave pattern among various individuals with the use of available technologies such as Electroencephalogram (EEG), Brain Computer Interface (BCI) system and Emotiv/Epoc+ Headband. Though the signals generated from human brain have common frequency categories, it has significant variation from person to person even for the same activities. The objective of this research is to analyse the variations of human brainwave patterns for similar activities among various individuals. The procedure of the experiment is to record data from 10 healthy participants. Each participant conducted three trials Thus; 40 recordings of raw EEG signals were collected with associated labels. Each trial started with a silent period of 30 seconds to 60 seconds, which will use as a baseline, then relaxation music and video for one minute. After completion of data acquisition, the saved data are plotted in to different graphs according to the channel. Finally, obtained wave patterns are analysed, in order to identify the variations. In general these human brain wave spectrums are varying person to person due to various reasons such as mind set of the person during an activity, healthy level of the person, placement of the electrodes on the head etc. In addition, the brain wave pattern corresponding to a similar human activity varies for different individuals.
