Usability must be defined specifically for the context of use of the particular system under investigation. This specific context of use should also be used to guide the definition of specific usability criteria and the selection of appropriate evaluation methods. There are four principles which can guide the selection of evaluation methods, relating to the information required in the evaluation, the stage at which to apply methods, the resources required and the people involved in the evaluation. This paper presents a framework for the evaluation of usability in the context of In-Vehicle Information Systems (IVISs). This framework guides designers through defining usability criteria for an evaluation, selecting appropriate evaluation methods and applying those methods. These stages form an iterative process of design-evaluation-redesign with the overall aim of improving the usability of IVISs and enhancing the driving experience, without compromising the safety of the driver.
可用性必须针对所研究特定系统的使用上下文进行具体定义。该特定使用上下文还应用于指导特定可用性标准的定义和适当评估方法的选择。有四个原则可以指导评估方法的选择，这些原则与评估所需的信息、应用方法的阶段、所需资源以及参与评估的人员有关。本文提出了一个用于评估车载信息系统 (IVIS) 上下文的可用性的框架。该框架指导设计人员定义评估的可用性标准、选择适当的评估方法并应用这些方法。这些阶段形成了一个设计-评估-重新设计的迭代过程，其总体目标是提高 IVIS 的可用性并改善驾驶体验，同时不影响驾驶员的安全。
