중요사건기법(CIT) 기반의 건설기계 운전원을 위한 아이콘 디자인

다국어 초록 (Multilingual Abstract)

The advancement of technology and concerns regarding safety have led to increased interest in the field of smart construction machinery. However, most research in this area has primarily focused on the economic viability of specific equipment or environments, resulting in a significant lack of empirical studies that analyze user behavior based on design methodologies. Therefore, research into Human Machine Interface (HMI) design for the connectivity between construction machinery and operators, from a design perspective, is essential. In order to gather insights into the experiences and requirements of construction machinery operators, in-depth interviews were conducted with six operators, resulting in the collection of 44 accident case data. Additionally, 672 accident cases related to signaling from the National Safety Management Institute for Construction were selected and analyzed. The analysis involved using the Critical Incident Technique (CIT) as a significant event analysis tool to extract key elements for each case and select central phrases, which were then categorized into meaningful units. Based on these consolidated meaningful units, HMI icons were designed to flexibly represent various types of construction machinery and situations. Finally, the proposed icon designs were implemented in a virtual construction site using Unity3D, with the icons applied to the front windshield of virtual construction machinery. In order to assess the practical utility of the HMI icons in a real construction environment, in-depth interviews were carried out.
