PEN-Ivory is a pen-based computer system that uses structured data entry for creating patient progress notes. Users make simple gestures such as circles, lines, and scratch-outs to enter medical findings from a controlled vocabulary. The result of an interaction with PEN-Ivory is a computer-generated patient progress note in English prose. We designed PEN-Ivory's user interface in a principled way. We first created multiple working prototypes, each differing in one of three user-interface characteristics. Then we empirically evaluated the prototypes in a controlled, experimental setting for their efficiencies in enabling users to create patient progress notes. The prototype that allowed the fastest data entry had the following three user-interface characteristics: it used a paging form, used a fixed palette of modifiers, and made available all findings from the controlled vocabulary at once.
PEN-Ivory是一种基于笔的计算机系统，它使用结构化数据录入来创建患者病程记录。用户通过诸如画圈、画线和删除等简单手势，从受控词汇表中输入医学检查结果。与PEN-Ivory交互的结果是一篇用英文散文形式生成的计算机化患者病程记录。我们以一种有原则的方式设计了PEN-Ivory的用户界面。我们首先创建了多个工作原型，每个原型在三个用户界面特征中的一个方面有所不同。然后我们在一个受控的实验环境中对这些原型进行了实证评估，以考察它们在帮助用户创建患者病程记录方面的效率。允许最快数据录入的原型具有以下三个用户界面特征：它使用分页表单、使用固定的修饰符调色板，并一次性提供受控词汇表中的所有检查结果。
