| Abstract |
This study attempts to analyze characteristics of human EEG response to image stimulus to two media facade cases, the Galleria Department Store and the Seoul Square in Seoul, which have different expression methods of its contents. For this study, authors used the EEG(Electroencephalogram) measurement method and the study results are as follows. First, the image stimulus of the Galleria Department Store and the Seoul Square highly revitalized the theta band, compared to other bands, and other bands showed differences in the mean value of EEG as well. Second, our analysis of the activity of each brain part of the EEG band showed that each band and brain part showed differences to image stimulus. Furthermore, F4(t=2.558, p<0.5) channel in the frontal lobe of the alpha band, F4(t=-2.373, p<0.5) channel in the frontal lobe of the beta band and F3(t=-2.257, p<0.5) channel in the frontal lobe of the gamma band showed statistically significant differences, and all of them showed differences in the frontal lobe. Third, our analysis revealed that there was a significant correlation(significance level: p<0.05) between the parts of the EEG band influenced by image stimulus. In addition, 45 brain parts showed a high synchronicity of image stimulus to the Galleria Department Store and 50 brain parts showed a high synchronicity of image stimulus to the Seoul Square. Based on this result, authors conclude that more brain parts were used to process information of image stimulus for the Seoul Square. Lastly, our analysis of the EEG band activity between male and female groups influenced by image stimulus showed that the mean value of EEG is different in all the bands. |
