This paper describes a research project which aims at studying the ergonomic and cognitive value of EsQUIsE, a freehand design environment for architects. This sketch-based modeling software is implemented on a Tablet PC. The EsQUIsE software provides architects with the possibility to generate automatically 3D views from the freehand drawings. The first part of the paper deals with the usability of such a digital environment for sketching, and especially the use of the drawing areas. The second part of the paper is dedicated to the analysis of how 3D views are generated and used for exploring alternative solutions. Although in interviews architects rate 3D highly, in fact they do not produce a large volume of 3D sketches. Issues about visual and spatial reasoning in design are thus highlighted. Finally, the benefit of such a tool for creativity is questioned. [less ▲]

Teaching cooperation-related issues to AEC (Architecture, Engineering and Construction) students is a major stake nowadays. There are many reasons for that: construction projects become more and more complex and cooperation practices are evolving in both organizational and IT-based ways. It is notably for these reasons that the issue of IT is addressed in most of the AEC-oriented schools and universities. Traditionally IT is taught to support the tasks of each specific construction field (e.g. CAD for architects, simulation tools for static engineers etc.). The Digital Cooperative Studio, presented in this article, considers IT as a support to cooperation and especially its communication and coordination dimensions. Moreover, we describe here a living lab involving students, teachers and researchers. This strong link between research and teaching allows both the students to be “analysts” of their real project situations and the researchers to experiment their development in real project situations.

This paper is interested in the extent to which sketches and 3D representations are important in today's design process, particularly during the preliminary creative phases of product design. We question the relevance of sketches within systems of external representations and amongst the infinite possibilities offered by CAD tools. This exploratory research is conducted through 3 steps: an information gathering step where we assess the current state of art, a direct contact with designers through interviews and the testing of the existing theories through pragmatic experimentation. The project’s goal is to objectivize a Human Machine Interaction that could effectively and efficiently support the product designers in their creative phases. [less ▲]

Ce projet s’intéresse à la place que tient aujourd’hui l’esquisse et les représentations 3D au sein du processus de conception, et plus particulièrement au sein des phases amont de la création chez les designers de produit. La question posée est la pertinence de l’esquisse au sein du système global des représentations externes et sa place actuelle dans le monde des possibles offerts par la CAO. La finalité de la recherche est l’objectivation d’un concept IHM pouvant effectivement et efficacement supporter les designers en phase créative. [less ▲]

The goal of this work is to analyse the product designers’ main habits in creation and cognition, to study the sketches’ contributions to early stages of design processes (these sketches being one common feature in creation that designers have with architects) in order to evaluate if EsQUIsE could support product design. Several questions sequence this evaluation: i) What are the main product designers’ work’s methods? What type of projects do they usually approach? What kind of issues, constraints do they have to confront? ii) What are the cognitive processes involved during the design phases? iii) When and how do sketches enter these processes? What are their effectiveness, their main contributions and on the opposite their main limitations? iv) Assuming that sketches constitute for product designers an effective support for the early creative phases, what are their principal characteristics? What do they content? What are their predominant graphic codes in this particular domain? v) What are the nowadays Computer-aided design tools’ appointed functions in product design? What are their advantages and drawbacks? How could they become better adapted to preliminary design phases? These interrogations are considered thanks to the following work methodology: • First an information collecting through a short state of art. The following subjects are: projects and constraints analysis; technical background; summary of the principal creative and cognitive processes in design; study of sketches potentials; advantages and limitations of actual CAD tools and short listing of the main software used in product design. • Then a straight contact with designers through interviews in order to collect their points of view on the previous subjects. • Follow the appreciation of the previous theories and collected information thanks to the pragmatic character of two experiments. These experiments bring new elements. They afford a better understanding of the general design theories, they confirm the sketches’ and 3D representations’ contributions to the design processes and furnish the first basis of graphic codes’ and sketches contents’ analysis. • Finally, the observation of graphic designers during the modelling of a simple object permits the deeper analyse of the relationship the user maintains toward nowadays CAD tools. A summary of the multiple aspects EsQUIsE should present to efficiently support the early conception phases in product design concludes this research. [less ▲]

Cet article propose une réflexion relative au croquis synthétique utilisé en conception architecturale. Après avoir rappelé sa définition, nous illustrons et détaillons les caractéristiques de cette production graphique, intermédiaire entre l'esquisse conceptuelle et le plan net. Nous montrons ensuite l'intérêt à considérer cette production graphique spécifique comme un mode d'interface privilégié avec le monde numérique en conception. Le logiciel prototype IC&C - Interaction par Croquis de Composition - est ensuite succinctement décrit pour démontrer l'innovation et la pertinence de ce concept et montrer son niveau d'opérabilité actuel en DAO architecturale.
