Various studies have been conducted to assess the effects of 3D contents with glasses using electroencephalogram (EEG), but there is a limited research for 3D contents using autostereoscopic display. In this study, we focused to study for sub-b wave frequencies, covering, SMR, M-beta, and H-beta frequencies and various indices of the EEG was used to evaluate stress, attention, relaxation, and vigilance upon quality variation of autostereoscopic 3D images. There were statistical significance for M-beta and H-beta powers when watching for low-quality 3D images were higher than those for high-quality. For various EEG indices, stress and attention indices show statistically significant differences between low and high resolution of 3D images. Stress and attention indices were increased when watching for low-quality 3D images. These results suggest that subjects viewing low-quality 3D contents through lenticular lens experience more discomfort or fatigue than those for high-quality, which resulting from the greater M-beta and H-beta powers for those watching low-quality 3D contents. In conclusion, these results confirm that EEG analysis can be used as a tool for evaluating visual fatigue or stress when watching autostereoscopic display with lenticular lens type. |
