A STUDY ON DRIVER'S BRAIN WAVE CHARACTERISTICS OVER THE CHANGE OF THE HEADLAMP'S BRIGHTNESS

摘要

In this study, tests of brain waves were carried out to investigate the driver's physiologicalcharacteristics by the change of the headlight. The participants were 20 men in their 20s and twenty-three different conditions in combinations of waveform of light, voltage, and alteration time were used. The measurement of the brain waves was performed by internationally standardized 10-20 method using LXE3232-RF. The results were as follows. 1. From the results of the Brain wave Map analysis, it was suggested that waveform A increases mental stress and waveform B affects mental and visual stress. The longer the stimulation time, the more stress level was detected. 2. The voltage alteration time of B waveform should be kept less than 1500msec, and the voltage should not fall below 11.5V.
