PROBLEM TO BE SOLVED: To enable a worker's adaptability to steps in a manufacturing line to be objectively evaluated.SOLUTION: An adaptability evaluation device obtains information on body conditions of a worker at each point of time, in a state where steps to be measured are modelled in a simplified way by: detection points corresponding to s plurality of body sites of the worker who performs the steps to be measured; and lines connecting the detection points. The adaptability evaluation device compares the obtained information regarding the detection points or the lines with reference information set for the step to be measured to calculate an adaptive value for the step of the worker. Then, based on a result of the calculation, the adaptability evaluation device generates adaptability evaluation information to perform controls to be presented.SELECTED DRAWING: Figure 9
