抄録

Today we live in a highly technological and information-oriented society. Information access, including the Internet has made noticeable developments and grown on a worldwide level. In such a social background, it is a widely known fact that major changes from the use of manpower dependence type work to VDT work is taking place in major businesses today. This paper describes some design factors for a reasonable working enuironment which supports a combination of manmachine system for VDT work. The method of research notes "fragrance" and "lighting" as factors to be explored when designing a working environment. It also considers the influence which these factors have on productivity and workload from an experimental approach. The evaluation indexes in the experiment are obtained by measuring working efficiency and working quality in VDT work, mental changes (stability)-recorded by an EEG (electroencephalograph) measurement, and workload degree determined by a survey of subjective symptoms and a accommodation time. The results of this paper indicated the efficiency of "fragrance" and "lighting", resulting in the effect from interaction "fragrance" and "lighting" on working environment in VDT work.
