为增强现实 (AR) 应用程序制作用例原型有助于尽早找出功能需求，从而以目标导向的方式推动后续开发。这样做需要设计人员识别面向目标的交互，并在时空环境中映射这些交互之间的关联。考虑到映射可能产生的多种场景以及交互组件的具体性质，最近的 AR 原型方法缺乏支持来充分捕获和传达设计者和利益相关者在此过程中的意图。我们推出了 ImpersonatAR，这是一种基于移动设备的原型设计工具，它利用增强环境中的具体演示来支持多场景 AR 用例的原型设计和评估。该方法使用：(1) 使用化身和 3D 动画以具体演示的形式捕获事件或步骤，(2) 组织事件和步骤以构成多场景体验，最后 (3) 允许利益相关者通过与原型进行交互式角色扮演来探索场景。我们对 10 名参与者进行了一项用户研究，使用 ImpersonatAR 从两个不同的 AR 应用程序功能中构建用例原型。结果验证了 ImpersonatAR 通过不同场景的具体表示，促进了对多场景 AR 用例的多种设计可能性的探索和评估。
Prototyping use cases for augmented reality (AR) applications can be beneficial to elicit the functional requirements of the features early-on, to drive the subsequent development in a goal-oriented manner. Doing so would require designers to identify the goal-oriented interactions and map the associations between those interactions in a spatio-temporal context. Pertaining to the multiple scenarios that may result from the mapping, and the embodied nature of the interaction components, recent AR prototyping methods lack the support to adequately capture and communicate the intent of designers and stakeholders during this process. We present ImpersonatAR, a mobile-device-based prototyping tool that utilizes embodied demonstrations in the augmented environment to support prototyping and evaluation of multi-scenario AR use cases. The approach uses: (1) capturing events or steps in the form of embodied demonstrations using avatars and 3D animations, (2) organizing events and steps to compose multi-scenario experience, and finally (3) allowing stakeholders to explore the scenarios through interactive role-play with the prototypes. We conducted a user study with ten participants to prototype use cases using ImpersonatAR from two different AR application features. Results validated that ImpersonatAR promotes exploration and evaluation of diverse design possibilities of multi-scenario AR use cases through embodied representations of the different scenarios.
