Notre recherche s'inscrit dans le cadre du développement de logiciels basés sur le dessin à main levée dans le domaine de l'architecture. Dans cet article, nous étudions l’activité de "mise au net" de dessins lors de la phase d'esquisse préliminaire et cherchons à identifier des modifications de cette activité in-duites par un environnement logiciel. Nous observons quatre activités de conception, deux sur papier-crayon et deux sur environnement numérique et déduisons des conclusions opérationnelles pour le dé-veloppement de logiciels destinés à supporter le croquis d'architecture.

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.

In architectural design process, the human error has a particular status. The later it is detected, the more expensive it is. Moreover, some errors can not be detected given the current state of the design process and object definition. In this paper, we propose a model based on cognitive theories about human errors, applied to architectural preliminary design. In this model we classify the consequences of a design decision (direct, indirect, detected and undetected), we describe the steps of decision in architecture in relation to the process of errors detection and we introduce the concept of evolutive context.

This contribution aims to show a multidisciplinary method to understand and formalize design process, from a cognitive point of view, in the particular case of human errors in architectural preliminary design process. We first emphasize the importance of error detection and recovery in the sketching phase in architecture. After the description of our methodology, we explain the general theory and model on human error, the short study we made and our proposition of a model on hu- man error in architectural design. We finally conclude by giving some first re- quirements from this model in order to improve to the development of sketch- based CAD tools. [less ▲]

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 ▲]

This article examines the usefulness and impact of a new generation of sketch-based environments on the preliminary or conceptual stages of architectural design. It also contemplates new directions in the field of digital sketch interpretation, particularly in architecture. Our qualitative and exploratory study compares three different forms of preliminary architectural design activities: one architecture student in a conventional pencil and paper situation, and two other architecture students using different versions of EsQUIsE software on a Virtual Desktop. Our observations lead to three major conclusions: (1) An automatically generated 3D model is a useful feature for checking the volumes of a planned building. (2) In spite of imposing some limits, the EsQUIsE environment enables the user to make modifications in the nature of architectural representations. (3) Several “superposition design” approaches exist, partly structured by the design environment. [less ▲]

This article is the synthesis of the ICC research project, aiming at the development of a multimodal and portable interface supporting in real time scale setting of an architectural measurement sketch. Based on a participative process, we first expose and make a model of the traditional activities of measure taking and scale setting. We then describe the ICC software and show how the retooled activity changes, taking into account the help functions it brings. We describe the new structure of measurement activity with scale setting, the new drawing modes it induces. We conclude proposing some tracks for the software improvement. [less ▲]
