Why sketching?
As an active way of thinking, the method of sketching becomes a tool, for illustrating new insight. From hand anatomy issues regarding rehabilitation to prototyping tactile stimulation, the sketching functions as a way to carry out research with no particular goal besides expressing input. To put down insight and information, stands as a principle for layering inspiration. To store research information by sketching is another way of documenting insight, and a discipline a designer for example, might seek more comfort in than others as it relies on drawing skills and visual transformation of knowledgeably facts.
To make visual information creates a method for the empathic design approach. By translating information in a user-friendly manner, the message could be perceived easier and thereby quicker accepted by its reader. As the authors of Universal Principles of Design put it, “Aesthetic designs are perceived as easier to use than less-aesthetic designs” (Butler, Holden and Lidwell, 2003, p. 18).
With a lot of insight gathered through design research, either handwritten, sketched, sound recorded or video filmed; I suggest this information should be visually transformed to be easily understood by its purpose.
