Human engineering design of hardware is especially important to reduce human error in earthquake. In this paper, at first, the degree of activity interference caused by sinusoidal vibration is clarified with objective indicator. Secondly, the factor which depresses working efficiency under sinusoidal vibration is clarified with objective and physiological indicator in VDT work. Finally, based on the consequences, we propose a method that enables quantitative evaluation for control/display layout. Then, the efficiency of the method in emergency situation is clarified with respective indicator under sinusoidal vibration and earthquake excitation of Hyogo-ken Nanbu (NS818gal, UD332gal). Main results obtained from this research are as follows. The greatest increment of respective indicator caused by vibration was observed at the resonance frequency of peak acceleration. The depression of working efficiency depended on the fatigue of vibration and workload. The method proposed in this paper could explain objective indicator in emergency situation.
