本文提出了一种解决计算机绘图/笔记程序中的模式问题的方法。传统上，在执行笔划之前，用户必须指定预期的“绘制”或“命令”模式。这种必要性已被证明是笔/指示笔系统可用性的障碍。我们提出了一种新颖的推理模式交互协议，避免了传统草图系统的模式麻烦。如果可能，该系统从笔轨迹的属性和轨迹的上下文中推断用户的意图。如果意图不明确，则向用户提供弹出按钮形式的选择调解器。为了最大限度地提高绘图的流动性，用户有权忽略调解人并继续绘图。我们给出了推断模式协议的决策逻辑，并讨论了在其开发过程中学到的细微之处。我们还给出了初步用户试验的结果，验证了该交互设计的可用性。
This paper offers a solution to the mode problem in computer sketch/notetaking programs. Conventionally, the user must specify the intended "draw" or "command" mode prior to performing a stroke. This necessity has proven to be a barrier to the usability of pen/stylus systems. We offer a novel Inferred-Mode interaction protocol that avoids the mode hassles of conventional sketch systems. The system infers the user's intent, if possible, from the properties of the pen trajectory and the context of the trajectory. If the intent is ambiguous, the user is offered a choice mediator in the form of a pop-up button. To maximize the fluidity of drawing, the user is entitled to ignore the mediator and continue drawing. We present decision logic for the inferred mode protocol, and discuss subtleties learned in the course of its development. We also present results of initial user trials validating the usability of this interaction design.
