可用性研究通常使用侧重于产品参数的方法。测试设计在实验室进行，评估通常由专家意见进行。对于验证性研究，我们想指出实地研究以及面向用户和系统的评估的重要性。为此，我们想提出的方法论方法iFlow(信息流)作为在真实或准真实(模拟)情况下可用性问题的多重评估技术。IFlow的思想是通过视频和音频记录结合工作负荷的主观和客观测量技术来评估输入和输出工作负荷。在这一贡献中，介绍了iFlow方法和麻醉学中的一项评价性研究。已经存在的方法和途径的附加值被考虑在iFlow的敏感性中，以描述性的方式识别超载情况。对于设计干预，参考iFlow图表来推断因果关系将是很有帮助的。
Usability studies often use methods focused on product parameters. Test designs are processed in laboratories and evaluation is commonly performed by expert opinions. For validation studies we want to point out the importance of field studies and user and system oriented evaluation. For this purpose we want to present the methodological approach iFlow (information flow) as multiple assessment technique for usability issues in real or quasi-real (simulated) situations. The idea of iFlow is to assess input and output workload via video and audio recordings combined with subjective and objective measurement techniques of workload. In this contribution the iFlow method and an evaluative study in anesthesiology are presented. The added value to already existing methods and approaches is considered in the sensitivity of iFlow to identify situations of overload in a descriptive way. For design interventions it would be helpful to consult the iFlow chart to deduct cause and effect relations.
