Extraction of tacit knowledge as expert engineer's skill based on mixed human sensing

We present a mixed human sensing method to extract tacit knowledge of skillful operation from expert engineers in the manufacturing industry. The 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. By returning and confirming the results of the analysis to the subjects, tacit knowledge is effectively extracted. Through the examinations applying the method to subjects operating in an industrial factory, the effectiveness of the method is shown.
