设计智能交互式文本输入系统通常依赖于使用传统HCI设计和评估方法难以估计或评估的因素。我们引入了一个互补的方法，通过适应工程设计的功能结构模型。我们通过从功能结构模型中提取可控和不可控参数并使用包络分析可视化其影响来扩展其使用。功能结构模型允许设计者从功能和功能之间的流程的角度理解系统，并将功能与功能载体分离。包络分析允许设计人员进一步研究参数如何影响感兴趣的变量，例如，精度，节省成本和其他因变量。我们提供的功能结构模型的例子，并说明了一个完整的信封分析，通过调查预测文本输入的参数化功能结构模型。我们讨论的影响，这种设计方法的文本输入系统的设计和批评系统的贡献。
Designing intelligent interactive text entry systems often relies on factors that are difficult to estimate or assess using traditional HCI design and evaluation methods. We introduce a complementary approach by adapting function structure models from engineering design. We extend their use by extracting controllable and uncontrollable parameters from function structure models and visualizing their impact using envelope analysis. Function structure models allow designers to understand a system in terms of its functions and flows between functions and decouple functions from function carriers. Envelope analysis allows the designer to further study how parameters affect variables of interest, for example, accuracy, keystroke savings and other dependent variables. We provide examples of function structure models and illustrate a complete envelope analysis by investigating a parameterized function structure model of predictive text entry. We discuss the implications of this design approach for both text entry system design and for critique of system contributions.
