本文概述了常用的HCI原型方法（从低保真到高保真）的空间，并断言，随着对这个空间的更好理解，HCI从业者将更好地将稀缺的原型资源用于可能产生特定结果的工作。它提出了一组五个维度，沿着这些维度可以对原型进行规划和表征。论文随后描述了NASA艾姆斯人机交互小组成员在考虑火星任务规划和调度工具的一套新工具的原型方法时对该空间进行的分析。本文描述了一个原型，该原型演示了设计解决方案，这些解决方案在传统的低保真度或中保真度原型方法下特别难以测试。所创建的原型是“混合保真”的，也就是说，在某些维度上高保真，而在其他维度上低保真。将原型与先前存在的正在重新设计的工具和使用原型开发的工具进行比较。实验数据表明，该原型可以很好地预测最终应用的最终用户性能。考虑到开发原型的相对成本，为了更精确地分配设计和开发资源，更好地描述保真度空间是至关重要的。
This paper presents a summary of the space of commonly-used HCI prototyping methods (low-fidelity to high-fidelity) and asserts that with a better understanding of this space, HCI practitioners will be better equipped to direct scarce prototyping resources toward an effort likely to yield specific results. It presents a set of five dimensions along which prototypes can be planned and characterized. The paper then describes an analysis of this space performed by members of the NASA Ames Human-Computer Interaction Group when considering prototyping approaches for a new set of tools for Mars mission planning and scheduling tools. A description is presented of a prototype that demonstrates design solutions that would have been particularly difficult to test given conventional low- or mid- fidelity prototyping methods. The prototype created was "mixed-fidelity," that is, high-fidelity on some dimensions and low-fidelity on others. The prototype is compared to a preexisting tool being redesigned and to a tool that has been developed using the prototype. Experimental data are presented that show the prototype to be a good predictor of eventual user performance with the final application. Given the relative cost of developing prototypes, it is critical to better characterize the space of fidelity in order to more precisely allocate design and development resources.
