Conversational composites: a method for illustration layering

The conversational nature of sketches is a widespread topic of research. Understanding drawing as a cognitive activity is commonly accepted, and many of the most extensively used methods within Human-Computer Interaction recruit sketching as a technique for ideation, explanation, documentation, and conversation. To further develop the use of this illustration process as a tool of knowledge production, we suggest a novel sketching method. We present Conversational Composites: a flexible method grounded in the material and tangible qualities of sketching in different forms and media, creating physical and digital layers of conversation between participants. We present and reflect on the proposed method through an applied case of a conversation between a PhD student and her supervisor, and offer suggestions on how it may be adapted and appropriated by other researchers in the HCI community.
