Effect of Oxygen Concentration and Odors on the Driving Fatigue in a Graphic Driving Simulator

다국어 초록 (Multilingual Abstract)

In this study, it was observed how 40% highly concentrated oxygen and lavender, peppermint affect the stress and fatigue which happen during driving performance and heart rate(HR). 12 male university students were selected as the subjects of this study. As a driving task, they were made to drive on the two-lane road for 5 minutes. While driving, addition tasks were added to increase the stress and fatigue. The driving performance like the above was implemented 6 times in total in the conditions of oxygen concentration (21%, 40%) and odors(normal, lavender, peppermint). For analysis, the findings were extracted by 30sec in three sections (Control, Driving, Driving + Task) and were compared. When the findings from three sections (Control, Driving, Driving + Task) were compared to identify driving fatigue , Driving +Task increased, showing a significant difference((p<0.01), compared with Control, That is, the subjects were made tired by addition tasks while driving. When highly concentrated oxygen (40%) and lavender, peppermint were presented to them, all of them showed the reduction of HR. That is, it can be said that highly concentrated oxygen and lavender, peppermint reduced the Fatigue of the drivers. When highly concentrated oxygen and lavender, peppermint were given simultaneously, there was no synergy effect.
