自動車模型分解における視線特徴の分析の試み

抄録

In recent years, advances in industry have improved technological capabilities, leading to increased functionality and complexity in products. During maintenance of complex products, it is rare to have work instructions for all components, and the absence of such instructions has led to occupational accidents, including those endangering lives. Consequently, in tasks such as disassembly for complex machinery maintenance, workers often need to determine the disassembly sequence themselves. Therefore, this study focuses on the eye movements of workers during product disassembly to discover insights that facilitate smooth disassembly operations. To analyze the characteristics of eye movements relevant to determining disassembly sequences, experiments were conducted where workers wore eye trackers and disassembled a model car with the objective of extracting specific components. Quantitative and qualitative analysis revealed a tendency for workers to begin disassembling from components they focused on, and to proceed to remove parts similar to those dealt with in the preceding steps.
