Abstract
This paper deals with the most suitable distribution of working hours with rest pauses for VDT workers from view points of their psycho-physiological reactions and work efficiency through the two series of the experiments.
From the results obtained, it can clearly be concluded that 60 minutes work with 10 minutes rest is the most recommendable for VDT workers to keep their fatigue level minimum and to increase their comfortability and productivity. And, it is also recommendable for those VDT workers working over 2 hours in a day should preferably take at least 15 minutes rest every 60 minutes work.
