Tacit knowledge extraction of skillful operation from expert engineers

We propose a novel method to extract tacit knowledge of skillful operation from expert engineers in the manufacturing industry. The data fusion analysis method that consists of the field-oriented interview, the human motion capture and the video analysis is applied for experts and beginners, and the operational differences between those are analyzed. The tacit knowledge is effectively extracted by returning and confirming the results of the analysis to the subjects. Through examinations applying the method to subjects operating in an industrial factory, the effectiveness of the method is shown.
