It is part of myÂ ongoing PhD discussions related to the use of external and internal representations.
Abstract. Previous empirical studies in sketches and mental imagery showed thatÂ there is no significant difference in overall quality and possibility to use mentalÂ imagery as design tool. This preliminary study explores distinctions between twoÂ kinds of sessions in terms of how ideas are generated. Four design sessions ofÂ two novice designers are used to unveil differences. Based on preliminary results,Â physical properties of sketches underlie differences, also the availability of visualÂ cues apart from the drawings itself. During interpretation stage, sketches providesÂ an additional dialogue which is not available in mental imagery session. The useÂ of mental imagery as design tool in novice designers vary and may not asÂ effective as in experts. Pauses and gesture in both sessions are found to beÂ fundamental designing aspects, including in environment when sketches areÂ allowed. When crucial differences are no longer assumed, interplaying rolesÂ between the two can then be explored further.
