Abstract

Sketching is considered a core activity in design and is a well-established practice in many areas of design. Interaction design is a new field of design that poses challenges for sketching, due to particular characteristics of the field such as being dynamic and "immaterial". In this study we focus on screen-based interactions, and particularly on rich interactions. To overcome these challenges one approach that has not been much explored is trying to improve sketches of interaction done on paper. With this in mind we propose ActionSketch, a technique that tries to accomplish this and is composed of four parts: frames, colors, symbols and rules. To validate the technique we conducted four workshops with 24 professionals, followed by a period of continued use of approximately three weeks. Our findings confirmed the need for better representations of interactions on sketches, offered insights into the benefits of using the proposed technique and indicated some opportunities for improvement. One major point for discussion is how the technique extends the current practice of sketching, and how it benefits from doing so.
