This paper proposes a framework for sketches analysis that could be useful for sketch-based interfaces development, in the particular context of preliminary activity-centred design. We will first describe our previous works on sketch-based support tools for the preliminary design phases and the context of these researches. The next chapter declares the concrete objectives of our approach, then the methodology of sketches analysis we propose is presented with a concrete example, and finally the last section is dedicated to the expected results and specifications of a sketch-based support tool that would follow our framework.

This paper presents a new supporting tool for distant collaborative design, named SketSha. This prototype supports the early stages of design and more particularly the initial and crucial step of free-hand sketching. SketSha and its particular interface, named the virtual desktop, aim to keep from Front-To-Front collaborative work all the benefits and to appoint to them some of the nowadays IT facilities, in order to manage in a realistic and efficient way a long distance collaboration and to effectively serve the designers’ needs. Our hope is to re-introduce the social aspects and group interactions, crucial for real system efficacy and adaptation to the business world. The paper presents the fundamental assumptions made to implement SketSha, that are questioned and analyzed through a real-size experimentation featuring 30 architecture and building engineering students, working together in real-time in different locations (Belgium and France). This experiment and the necessary survey open up interesting fields of investigations, such as the relevance of the sketch stage and the proposed device to support distant collaborative design in architecture and the benefit it represents for students, in a pedagogical point of view, to merge the IT aspects and the design studio. The methodology and the replicability are analyzed to increase the level and quality of our students’ formation and, finally, a critic of SketSha constitutes a benefit for the developing teams.

This paper introduces new supporting tools in the field of distant collaborative design, namely DCDS and CRTI-weB. These prototypes respectively support: the early stages of design, through the support of the crucial initial step of free-hand sketches shared in real-time, and the asynchronous collaborative activities. The main goal of this paper is to propose the use of these innovative tools as an efficient and realistic way of managing long distance collaboration, to effectively serve the designers’ needs. This proposition is analyzed and questioned through a real-size experiment featuring 30 architecture and architectural-engineering students, working together in real-time in different locations (Belgium and France). This experiment and the necessary survey open up interesting fields of investigation, such as the relevance of the proposed devices in supporting distant collaborative design in architecture and the benefit this represents for students to merge the IT aspects and the design studio. The methodology and the replicability are analyzed to increase the level and quality of formation of our students and, finally, a critique of the tools confirms a benefit for the developing teams.

An increasing number of large scale projects requires that distant teams collaborate together remotely. At the same time, the current CAD tools only offer minimal support for partial and asynchronous interactions. The application we propose enables full synchronous and remote sketch-based collaborative design. This setup is a combination of a virtual desktop (a remote meeting table), a standard videoconference system, a gesture recognition module and a networked, real-time, collaborative drawing software (SketSha). The solution as a whole is multimodal in essence (gestures, speech, drawing…) supporting immersive remote collaborative design. [less ▲]

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.
