摘要:

为提升医生使用手术机器人辅助诊疗过程中的认知体验,完成机器人手术系统交互界面设计迭代优化,确保系统救治的高效性与安全性而进行系统研究分析。首先,选取肝癌消融手术机器人交互界面为研究对象,基于BERT模型形成的自然语言处理技术(NLP),完成用户口语报告关键词提取与认知关联词汇筛选与分类,并通过亲和图法归纳和完善用户需求描述;在ICE三维评分模型基础上创新性融合理想点矢量投影法获取专家对各需求项的权重赋值,并参考开发成本筛选出关键需求;结合认知机制原理与FAST模型进行需求分析,完成需求层到设计层映射转化,并对迭代前后方案分别进行可用性测试,收集主、客观评价数据验证设计合理性。然后,以认知特性为切入点,综合运用定性与定量分析完成肝癌消融手术机器人界面设计迭代与优化。最后,通过可用性测试得出迭代后方案能够显著降低任务操作时长与无效操作频次,同时获取用户更高的体验评分。在机器人手术系统界面设计领域引入认知理论作为指导,综合运用BERT自然语言处理模型以及ICE-理想点矢量投影相结合的需求分析法进行设计分析,并以此为基础形成的设计方案能够提升原有界面可用性,优化操作过程认知体验,在理论和实践层面为机器人手术系统界面设计提供指引与参考。

Abstract:

This study aims to enhance the cognitive experience of doctors using surgical robots during the diagnostic and treatment process, and to complete the iterative optimization of the interface design of the robot surgery system to ensure the efficiency and safety of the treatment. First, the interaction interface of the liver cancer ablation surgery robot was selected as the research object, and the natural language processing technology (NLP) based on the BERT (bidirectional encoder representation from transformers) model was used to extract key words from the user’s spoken report and select and classify cognitive related vocabulary. User needs were summarized and refined through the affinity diagram method. The expert’s weight assignment for each demand item were calculated using an innovative combination of the ICE (impact confidence ease) three-dimensional scoring model and the ideal point vector projection method. The key needs were selected based on the development cost and reference to the cognitive mechanism principles and FAST (function analysis system technique) model. User requirements were analyzed and transformed into design layers through a combination of cognitive mechanism principles and FAST model. The schemes before and after iteration were subjected to usability testing, collecting objective and subjective evaluation data to verify the rationality of the design. Then, the cognitive characteristics were taken as the entry point, and the design iteration and optimization of the liver cancer ablation surgery robot interface were completed through a combination of qualitative and quantitative analysis. Finally, the usability test demonstrated that the post-iteration design can significantly reduce the operation time and the frequency of ineffective operations, while achieving higher user experience scores. Introducing cognitive theory as a guide in the interface design of robot surgery systems, and combining the BERT natural language processing model with the ICE-ideal point vector projection demand analysis method, this approach enhanced the usability of the original interface, optimized the cognitive experience of the operation process, and provide guidance and reference in theory and practice for the interface design of robot surgery systems.
