<p>PURPOSE: To make it possible to automatically estimate the degree of fatigue, the degradation in the degree of awakening and degree of concentration, etc., without manual labor. CONSTITUTION: The results detected by a detecting means 1a and detecting means 1c consisting of sensors respectively selected from a vital information sensor group are respectively subjected to calculation of the corresponding operation load by the kinds of the sensors and their utilizing means in an analyzing means 1b and 1d. At this time, the time for referencing the results of the detection is earlier in the detecting means 1a than in the detecting means 1c. In addition, the distance in the time between both corresponds to the rest period of the operator. A comparing means 1e compares the analysis values 1, 2 of the analyzing means 1b, 1d. The references for comparison meeting the sensors selected from the vital information sensor groups are used for the reference for comparison. The purposes of the reference for comparison are to make judgment as the the permissible conditions of the working load or the conditions exceeding the permission of the operation load.</p> |
