Growing the practice of vocal sketching

Sketch-thinking in the design domain is a complex representational activity, emerging from the reflective conversation with the sketch. A recent line of research on computational support for sound design has been focusing on the exploitation of voice, and especially vocal imitations, as effective representation strategy for the early stage of the design process. A set of introductory exercises on vocal sketching, to probe the communication effectiveness of vocal imitations for design purposes, are presented and discussed, in the scope of the research-through-design workshop activities of the EU project SkAT-VG. 1. BACKGROUND In many everyday life situations, people find more effective and economical to support their reasoning by backing or even replacing verbal communication with sketches. In most cases, this inherently knowledge-based activity takes the form of drawings, that is visual representations of direct percepts or mental images, aimed at quick recording and processing of information, and its communication. The etymology of the word “sketch” goes back to the ancient Greek term σχ´ eδιoς 1 , which means “done or made offhand, on
