“…As mentioned throughout this paper, the use of mental imagery is an entirely internal process, meaning that designers live within their own catalogue of images and design can rely on the interaction between this internal process and external processes, such as sketching (Athavankar, 1997;Bilda & Gero, 2008;Tedjosaputro et al, 2014). Most designers would argue that sketching is an essential step in the design process ICED23 (Athavankar, 1997) and it is a simple yet reliable method of communication and reasoning which encourages the development of ideas (Goldschmidt, 1991;Bilda & Gero, 2008;Tedjosaputro et al, 2014). Sketching is particularly useful within design teams as it increases communication by allowing ideas and images to be shared more easily (Goldschmidt, 2007).…”
