To gain a common understanding of an application’s layouts, dialogs and interaction flows, development teams often sketch user interface (UI). Nowadays, they must also define multi-touch gestures, but tools for sketching UIs often lack support for custom gestures and typically just integrate a basic predefined gesture set, which might not suffice to specifically tailor the interaction to the desired use cases. Furthermore, sketching can be enhanced with digital means, but it remains unclear whether digital sketching is actually beneficial when designing gesture-based applications. We extended the AugIR, a digital sketching environment, with GestureCards, a hybrid gesture notation, to allow software engineers to define custom gestures when sketching UIs. We evaluated our approach in a user study contrasting digital and analog sketching of gesture-based UIs.

AugIR 与 GestureCards 相遇：基于手势应用的数字素描环境

为了对应用程序的布局、对话框和交互流程有一个共同的理解，开发团队通常会绘制用户界面 (UI)。如今，他们还必须定义多点触控手势，但用于绘制 UI 的工具通常缺乏对自定义手势的支持，并且通常只集成一个基本的预定义手势集，这可能不足以专门针对所需用例定制交互。此外，素描可以通过数字手段得到增强，但在设计基于手势的应用程序时，数字素描是否真的有益尚不清楚。我们使用 GestureCards（一种混合手势符号）扩展了数字绘图环境 AugIR，以允许软件工程师在绘制 UI 时定义自定义手势。
