Leveraging ergonomics and computer science in the construction industry: Effectivity of digital tools-based training for technicians

Abstract

This study addresses the labor shortage and aging workforce in Japan’s construction industry by exploring the effectiveness of training with digital tools that visualize the “knack” of skills through superimposed eye-gaze points during a machine excavation task. The gazing point video of excavator during work was taken prior to the test. A web-based questionnaire test was conducted, with the Test Group watching the eye-gaze superimposed video and the Control Group watching the same video without gaze points. While overall responses between the groups were similar, question-level analysis revealed variations, suggesting that the eye-gaze visualization method shows potential effectiveness, although further exploration is needed to improve methods to express and convey these insights.
