This paper describes an innovative approach to the evaluation of the user interface and vocabulary of a medical information system. The use of video recording for collecting usability data is detailed. The technique employed involves the collection of data consisting of transcripts of physicians as they "think aloud" while interacting with the system, along with a video record of the complete user-computer interaction. Using methods of analysis from cognitive science, the study was able to distinguish the source of physician problems in using the system's interface and in interacting with its controlled medical vocabulary. Analysis of the protocols indicated that all subjects encountered several generic problems, the most common ones indicative of a need for greater consistency in the interface design. Based on this evaluation, parts of the user interface have been re-implemented in an ongoing process of iterative system development.
本文描述了一种评估医学信息系统用户界面和词汇表的创新方法。详细介绍了使用视频记录来收集可用性数据的情况。所采用的技术包括收集数据，这些数据由医生在与系统交互时“边思考边说”的文字记录以及完整的用户与计算机交互的视频记录组成。通过运用认知科学的分析方法，该研究能够辨别医生在使用系统界面以及与系统的受控医学词汇交互时出现问题的根源。对这些记录的分析表明，所有受试者都遇到了几个常见问题，其中最常见的问题表明在界面设计中需要更高的一致性。基于这一评估，在持续的迭代系统开发过程中，用户界面的部分内容已重新实现。
