ELECTROENCEPHALOGRAM (EEG) STUDIES ON HUMAN PERCEPTION IN COLOURS
Abstract
This manuscript presents an investigation of human perception on colors using the Electroencephalogram (EEG) device. Studies of the human perception using EEG is expanding in various discipline that links electronics to many fields of study interest. The aim of this study is to observe the human perception and its level of calmness in the brain. Observation was made on the alpha band that was generated from various kinds of colors to different human. This study further focused on the EEG frequency of Alpha brainwaves and its relation to the brain lobes. In this experiment, the low-cost Emotive Epoch EEG neuroheadset device with 16 channels of electrodes were used. Subjects were instructed to look into different colors displays during the experiment. The EEG data was analyzed using the Fourier transform of Power Spectral Density (PSD). The results were observed from all the lobes but focusing were made on the occipital lobe and the averages of the alpha waves Power Spectral Density in two channels of the occipital were obtained. The analysis result from this study showed that the alpha wave produced from different participants are affected through different colors. This observation further depicted that human are calm through their color of interest.
