“…Various approaches have been developed for the assessment of individual sketches [17,68] and design reports and journals [72,[172][173][174][175]. Some studies employ expert judges [10,108,[176][177][178][179]. In social sciences, it is common to see multiple judges so as to remove bias.…”

Understanding how designers think is core to advancing design methods, tools, and outcomes. Engineering researchers have effectively turned to cognitive science approaches to studying the engineering design process. Empirical methods used for studying designer thinking have included verbal protocols, case studies, and controlled experiments. Studies have looked at the role of design methods, strategies, tools, environment, experience, and group dynamics. Early empirical studies were casual and exploratory with loosely defined objectives and informal analysis methods. Current studies have become more formal, factor controlled, aiming at hypothesis testing, using statistical design of experiments (DOE) and analysis methods such as analysis of variations (ANOVA). Popular pursuits include comparison of experts and novices, identifying and overcoming fixation, role of analogies, effectiveness of ideation methods, and other various tools. This paper first reviews a snapshot of the different approaches to study designers and their processes. Once the current basis is established, the paper explores directions for future or expanded research in this rich and critical area of designer thinking. A variety of data may be collected, and related to both the process and the outcome (designs). But there are still no standards for designing, collecting and analyzing data, partly due to the lack of cognitive models and theories of designer thinking. Data analysis is tedious and the rate of discoveries has been slow. Future studies may need to develop computer based data collection and automated analyses, which may facilitate collection of massive amounts of data with the potential of rapid advancement of the rate of discoveries and development of designer thinking cognitive models. The purpose of this paper is to provide a roadmap to the vast literature for the benefit of new researchers, and also a retrospective for the community.

“…Visual displays with structural similarities are reported to be superior to surface similarities (Gassmann & Zeschky, 2008). Multiple kinds of distant text stimuli involving emotional words (Nagai & Noguchi, 2003), high level general verbs (Chiu & Shu, 2007), incongruent words (Chiu & Shu, 2008), sound-symbolic words (Mougenot & Watanabe, 2011), text of non-obvious semantic meanings (Chiu & Shu, 2012), and text describing distant related objects (Gonçalves, Cardoso, & Badke-Schaub, 2012), are reported to enhance the creativity of ideas.…”

Sketching is widely used in design to generate creative ideas. Design studies present stimuli during sketching to enhance creativity. This study examines the effect of stimuli presented during different sketching states, especially of those presented during the stuck period. It conducted a sketching experiment that enrolled 41 students with an average of 5.7 years' practice in industrial design. The sketching with stimuli presented at regular intervals, those with stimuli presented during the stuck period, and those without stimulus were compared. Eye movements during the sketching processes were recorded. The attention to stimuli, and the direct applications of stimuli to design ideas, and the idea connection and idea differentiation were analyzed. Participants sketching with stimuli presented during the stuck period had a higher sketching quality, compared with those in other experimental conditions. They fixated longer on stimuli, built more links among related ideas, and had a more differentiated and balanced exploration. This study then proposed the mechanisms of stimuli processing. The stimuli presented at regular intervals were stored and acted as additional memory. The stimuli presented during the stuck period were dissected and acted as supporter, inducing a more creative sketching.

Depth impressions are an inward associative layer of the expressed impressions of humans. To analyze tactile interaction, it is essential to examine what users feel and imagine and how they create depth impressions by touching and looking at different materials. On the basis of tactile interactions, this study captures and analyzes users' depth impressions on materials. We propose impressionable new tactile material for design from the viewpoint of depth impressions and emotional engineering. We employed a concept networks-based method to analyze the experimentally obtained verbalized protocols and to identify the depth impressions. We found that the feel of materials' tactile naturalness is related to the depth impressions and concept networks' complexity. The depth impressions and concept network of the proposed micro-print material are distinct and beyond that of existing natural or artificial materials. These findings will help in employing new analysis tools and developing better tactile materials for designing products.
