On the Balance of Skill and Operation : 2 nd Report, The Relation between the Flicker Value and the Operational Ability of Workers during the Operation of the Simulator

抄録

This paper deals with the relation between the operational ability of workers and the work load shown by the flicker value measurement. The subjects are assigned to operate a simulator of the motor-man's platform of the automobile under working conditions, in which subjects are obliged to watch one, two or three vigilance objects. The flicker value and the frequency of missing objects are measured in working hours and analysed by the statistical multivariate method. It is made clear that the work load of a subject increases as the number of objects increases. And the subject who directs his attention to a certain vigilance object can direct also his attention to other objects and his operational ability is very high but his work load is very heavy. Further the work load on the subject, whose operational ability to all vigilance objects is medium, is lightest. Therefore, it is possible to select workers who are fit for work by these results.
