有意义的人为因素应用于人机任务的设计需要一个定量的数据库，该数据库将操作员的行为描述为各种自变量的函数。三类指标(操作员满意度评分、工作抽样程序和嵌入式绩效测量)被描述为评估用于输入和更新人员记录的人机界面的重要指标。使用多项式回归程序来生成这些度量中的每一个与代表系统延迟、显示速率、键盘回声速率和键盘缓冲区长度的四个自变量之间的函数关系。这22个独立的因变量中的每一个都显示了四个系统变量之间不同的函数关系，但总体系统延迟和键盘回声速率是操作员行为的主要决定因素。此外，这三类指标被组合成与操作员生产、等待和计划活动相关的三个基本接口维度。
Meaningful human factors applications to the design of human-computer tasks require a quantitative data base that describes operator behavior as a function of various independent variables. Three classes of metrics (operator satisfaction ratings, work-sampling procedures, and embedded performance measurement) are described as important measures in evaluating a human-computer interface used to enter and update personnel records. Polynomial regression procedures were used to generate functional relationships between each of these metrics and four independent variables representing system delay, display rate, keyboard echo rate, and keyboard buffer length. Each of the 22 separate dependent variables showed different functional relationships among the four systems variables, but overall system delay and keyboard echo rate were the major determiners of operator behavior. Additionally, the three classes of metrics were combined into three underlying interface dimensions relating to operator production, waiting, and planning activities.
