The process of interaction design involves multiple stages beginning from user research and ideation that lead to working prototypes and user evaluation. Sketching is considered to be important in the early interaction design stages as a way to explore, store, but also communicate ideas. Sketching is, however, a graphical process and it is not always easy to integrate sound to it, even though sound is an important part of interaction. Sketching sound, on the other hand, has received significant attention in sound design. Here, we contrast sketching in interaction design with sketching sound in order to understand whether ideas from sound sketching can be relevant when sketching interaction. The literature indicates that sketching sound has been done almost exclusively in the auditory modality and takes place in a largely independent process that is not entirely harmonized with traditional graphical sketching and interaction design practices. While this may make sense when designing sonic interactions, it is not as supportive for other interaction design contexts. We discuss this finding while taking into account graphical approaches to sketching sound in the literature.
