This research work is an explorative study to measure efficiency, effectiveness and user satisfaction of a prototype called Infobiotika aiming to support antibiotic use in intensive care. The evaluation was performed by combining traditional usability testing with eye-tracking technology. The test was conducted with eight intensive care physicians whereof four specialists and four residents. During three test phases participants were asked to perform three types of tasks, namely navigational, clinical and tasks to measure the learning effect after 3-5 minutes free exploring time. A post-test questionnaire was used to explore user satisfaction. Based on the results and overall observations, Infobiotika seems to be effective and efficient in terms of supporting navigation and also a learnable product for intensive care physicians fulfilling their need to get an accurate overview of a patient status quickly. Applying eye-tracking technology during usability testing has shown to be a valuable complement to traditional methods that revealed many unexpected issues in terms of navigation and contributed a supplementary understanding about design problems and user performance.
本研究工作是一项探索性研究，旨在衡量一款名为Infobiotika的原型的效率、有效性和用户满意度，该原型旨在支持重症监护中的抗生素使用。评估通过将传统可用性测试与眼动追踪技术相结合来进行。测试是在八位重症监护医生中进行的，其中四位是专家，四位是住院医生。在三个测试阶段中，要求参与者执行三种类型的任务，即导航任务、临床任务以及在3至5分钟的自由探索时间后测量学习效果的任务。使用测试后问卷来探究用户满意度。基于结果和总体观察，Infobiotika在支持导航方面似乎是有效且高效的，并且对于重症监护医生来说是一款可学习的产品，能够满足他们快速准确了解患者状况的需求。在可用性测试期间应用眼动追踪技术已证明是对传统方法的宝贵补充，传统方法揭示了许多在导航方面意想不到的问题，并有助于对设计问题和用户表现有补充性的理解。
