Evaluation on the Effects of Visual Intervention on Emotion and Fatigue while Driving Using Brainwave Indicator

In this modern era, driving has become one of the most common habit that humans do. However, this phenomenon can lead to a big problem. The more people drive, the higher the chance of a traffic accident can occur. This study investigated the effects of visual intervention on emotion and fatigue in car driving simulation using brainwave indicator or changes in electroencephalography (EEG). Frontal Alpha Asymmetry (FAA) method were used to determine the effects on emotion while Ratio method were used to determine the effects on fatigue level. Twenty males were recruited to perform a 40 minutes car driving simulation while frontal channel of EEG was recorded. This was a within subject experiment where each participant was given both no intervention and visual intervention treatment. For the FAA method, the no intervention had a tendency to fluctuate. Therefore, inducing both positive and negative emotions. Meanwhile, the visual intervention remains on the positive side throughout the driving session indicating that the visual intervention induced a more positive emotion. The results for the repeated measure test also indicate that there is a significant difference between interventions. For the Ratio, the fatigue level was decreased for the first 30 minutes on visual intervention. Meanwhile, the fatigue level did not decrease at all for no intervention. Significant differences were found on the first 30 minutes while for the last 10 minutes there were no significant differences. These findings can be utilized as baseline for a more comprehensive research regarding traffic safety.
