了解工程师在解决问题过程中的行为是必要的，以便提供合适的方法，支持工程师在日常工作中。为了观察和记录他们在实验研究中的行为，本文介绍了在研究设计中使用眼动仪观察工程设计师的综合驱动分析过程的经验。研究的设计任务旨在接近工程实践任务。因此，分析和综合没有被分离，并且可以观察到综合驱动的分析过程。一项探索性研究显示了实验设计的可能性和优势，使用眼动仪观察工程设计师在综合驱动的分析过程中的行为。几种类型的材料被提供给受试者，以便在其分析过程中不限制它们。实验设置应满足任务设计和任务分析的要求：客观性、信度、效度、实证相关性和适当的难度。跟踪的注视数据对满足这些需求有很大贡献。本文介绍了如何处理眼动数据的可能性，旨在了解工程师的分析过程。自上而下的刺激和重叠的利益领域的代表性，使一个灵活的观察对象的过程和行动方针。探索性研究能够满足实验和任务设计的客观性、信度、效度和实证相关性的要求。对于所选的受试者组，可以验证任务的适当难度。工程设计师在综合驱动分析过程中的行为差异是进一步实证研究的内容。
Understanding the engineers’ behavior during problem solving is necessary in order to provide suitable methods, which support engineers during their daily work. For observing and recording their behavior in experimental studies, this paper presents experiences in the study design using eye tracking for observing synthesis-driven analysis processes of engineering designers. The design task of the study aims to be close to tasks of engineering practices. Hereby, analysis and synthesis are not separated and the synthesis-driven analysis processes can be observed. An explorative study shows possibilities and advantages of the experimental design, using eye tracking for observing the engineering designers’ behavior in synthesis-driven analysis processes. Several kinds of materials are provided to the subject for not limiting them in their analysis processes. The experimental setup should meet the demands on the task design and task analysis: objectivity, reliability, validity, empirical relevance and adequate difficulty. The tracked gaze data contributes significantly to fulfil these demands. The paper presents possibilities how to process the eye tracking data with the aim to understand the analysis processes of engineers. A top-down representation of the stimulus and overlapping areas of interests enable a flexible observation of the subjects’ processes and courses of actions. The demands on the experimental and task design – objectivity, reliability, validity and empirical relevance – could be met in the explorative study. An adequate difficulty of the task can be verified for the chosen group of subjects. Differences in the behavior of engineering designers during synthesis-driven analysis are the content of further empirical studies.
