“…As a result, Robertson and Radcliffe [3] note that use of CAD can result in premature fixation because of a reluctance to incorporate ideas that will result in too many changes to a constructed design model or its underlying structure. Fundamentally, this issue manifests because digital design models impose a distance between designers and the representations that they work with, a distance which does not arise with physical design media, such as sketches [15].…”

“…Pen (cil) and paper remain the media of choice for ideation and creative design [2]. For example, Robertson and Radcliff [3] report the outcomes of a survey that questioned CAD users concerning the impact of CAD on creative problem solving. They found that use of CAD results in enhanced visualisation and communication but also an increase in circumscribed thinking and premature fixation.…”

Throughout the history of CAD, a variety of interfaces have been employed with the aim of supporting designers' construction and manipulation of digital models. This paper explores the potential of eye tracking as a CAD interface, and presents a prototype that uses collected gaze data to support shape exploration in a two-dimensional vectorbased sketch editor. The eye tracking interface uses the visual interactions of users to identify interpretations of constructed shapes, according to recognised parts identified using methods from shape grammar research. It can therefore be argued that it supports construction and manipulation of shapes according to user intent. The prototype has been evaluated in a user study where design students carried out controlled shape exploration exercises which involved interpretation and manipulation of shapes. In the paper, key concepts of eye tracking methodology are introduced; the methods used to implement the eye tracking interface are described; and the user study and its outcomes are reported. The results are positive and indicate the potential for eye tracking as an interface for supporting shape exploration in CAD. Research Highlights• Explores the potential of eye tracking as an interface for computer aided-design• Describes methods for inferring user intent with respect to digital shape manipulation, based on gaze data • Presents a prototype eye tracking interface that supports dynamic shape interpretation in a vector-based sketch editor • Reports the outcomes of a user study that evaluates how successful the eye tracking interface is at inferring users' intent with respect to shape manipulation

“…Initialement conçus afin d'optimiser, d'évaluer et de mettre en plan de production des objets dont la conception en tant que telle est considérée comme achevée, ces outils ont rapidement vu leur utilisation détournée et adaptée à d'autres fins par leurs utilisateurs. Ils sont devenus support à la communication, argument de vente par les visualisations qu'ils outillent et même support à la créativité pour certains concepteurs les convoquant de plus au plus tôt au sein du processus de conception (Robertson et Radcliffe, 2009 ;Elsen et al, 2010). S'ils bouleversent effectivement les pratiques quotidiennes de ces métiers, plusieurs études révèlent cependant que l'esquisse à main levée reste bien, pour la plupart des ces domaines, l'outil favori pendant les phases déterminantes de conception préliminaire (Leclercq et Elsen, 2007 ;Elsen et al, 2010).…”

RESUMECet article traite de la passation graphique d'une intention et révèle, par l'intermédiaire d'expérimentations ciblées, quels composants graphiques soutiennent particulièrement bien ou mal cette passation. Les résultats suggèrent d'apporter une attention toute particulière, que l'on soit concepteur--collaborateur ou développeur d'interfaces de soutien à la collaboration distante, aux courbes dites « principales ». Celles--ci semblent effectivement être garantes d'une intention graphique potentiellement mieux transmise et mieux capturée -l'essence graphique d'une collaboration distante efficace. ABSTRACTThis paper deals with the graphical transfer of an intention and underlines, through several controlled experiments, which graphical components are better adapted to support this transfer. Results suggest that one should pay particular attention to « principal curves », being either collaborating designer or software engineer in charge of designing new--generation interfaces to support distant collaboration. Those principal curves indeed seem to insure better transmission (and better capture) of graphical intentions -the fundamental graphic essence of an efficient distant collaboration.

“…Such tools can scaffold the design thinking process and help them accomplish a task that is beyond their current abilities 5 . A survey of CAD designers revealed that CAD tools support creative problem solving process by supporting "enhanced visualization and communication, circumscribed thinking, premature design fixation and bounded ideation" (p.136 ) 6 . However, the focus on developing such skills and the use of such tools in the classroom context is not widespread and often overlooked by educators 7 .…”

Manaz is a Master's student in Computer Information Technology at Purdue University who's research is focused on CAD simulations' effect on students' design thinking skills when tackling messy problems. Dr. Chandan Dasgupta, Purdue UniversityDr. Chandan Dasgupta received his Ph.D. in Learning Sciences from the University of Illinois at Chicago (UIC) where he was awarded the Chancellor's graduate research fellowship for his dissertation work on scaffolding students' productive disciplinary engagement with engineering design activities using suboptimal models. His research interests include the use of counterexamples as primary generators for supporting productive disciplinary engagement, integration of design thinking and scientific inquiry into K-12 education, and designing learning environments that help students generate and use design heuristics and make effective tradeoff decisions.John Alexander Mendoza-Garcia MSSEC, Purdue University, West Lafayette John Mendoza-Garcia is a Colombian Systems Engineer, and currently a Ph.D. candidate in Engineering Education at Purdue University. His advisors are Dr. Monica E. Cardella and Dr. William C. Oakes. In his dissertation, he is interested in understanding the development of the ability to deal with problems in Engineering complex socio-technical systems via variation theory. Other interests are curriculum development for mathematical thinking, design thinking, and human-centered design. He is currently on a leave of absence from the department of systems engineering at Pontificia Universidad Javeriana in Colombia. He worked as a software engineer in different companies for seven years before transitioning to academia. INVESTIGATING THE IMPACT OF AN EDUCATIONAL CAD MODELING TOOL ON STUDENT DESIGN THINKING AbstractIn this work-in-progress paper we present preliminary results of a study on the use of computeraided design (CAD) software to develop informed designers at the first year undergraduate level.There is a need for first-year undergraduate engineering students to engage productively with engineering design practices while using a CAD software in a group setting in a classroom environment. Existing research has classified students as mostly beginning designers or informed designers. The data collected are reflections written by 10 students in an introductory design course, one reflection after working individually in a design of an energy efficient house and another after working as part of a team on the same problem. The data were analyzed using as conceptual framework the informed design teaching and learning matrix developed by Crismond and Adams. Findings suggest the presence of a continuum consisting of four levels and highlight the shift in students' design practices towards higher expertise levels after using the CAD software in a group setting. While these are preliminary findings, they highlight the potential value of engaging first year engineering students with a CAD software in a group setting within formal classroom environment.
