Abstract

In recent years, with the introduction of O. A. equipment in most offices, the computer has become indispensable to enhance work efficiency. Especially, in our time, it is a surfeit of the information society. Human beings are always exposed to things that stimulate them. Under such conditions, they begin to feel both physical and emotional stress. Exceeding the stress limit can cause psychosomatic problems. So it is important to design an efficient work environment that causes a minimal burden in terms of human health. Therefore, this paper discusses design factors for a reasonable work environment regarding visual display terminal (VDT) work in consideration of the influence of work environment factors on productivity and workload. The method of research was to observe and measure the influence of number of workers and fragrance on workers involved in using VDT. The evaluation index used in this study considered productivity (quantity, quality), workload (EEG), a survey of subjective symptoms and eye fatigue. As a result of research, the number of workers (one person) and fragrances to stimulate awareness, at a 20% density, are important as reasonable work environment factors in VDT work.
