L'article présente la démarche de développement d’une méthode logicielle de modélisation architecturale, développée à l'intention des acousticiens chargés de formuler les options technologiques nécessaires pour assurer les performances acoustiques d’un bâtiment (salle de concert, auditoire, théâtre, etc.). Basé sur une approche "centrée utilisateur", l'outil facilite grandement la description géométrique et technologique de l'espace intérieur en conception. Nous présentons d’abord l’analyse d’activité d’un acousticien qui nous a permis de poser les grandes options du modeleur. Nous décrivons ensuite les principes d’interaction qui sous-tendent l’application et nous illustrons ses atouts et parti-cularités par rapport aux méthodes actuelles. Finalement, nous commentons une première évaluation et nous discutons de la pertinence du développement d’outils de modélisation spécialisés. [less ▲]

Cette étude s’intéresse à l’assignation des propriétés technologiques des parois dans un modeleur architectural 3D. Nous proposons une méthode originale basée sur le principe de groupements sémantiques de faces par requêtes géométriques. Nous décrivons la méthode et les résultats d’entretiens menés auprès d’architectes pour identifier les groupements pertinents, listons les requêtes géométriques simples pour la sélection de ces groupements et rendons compte de l’efficacité de la méthode sur un cas. Nous concluons sur les avantages et limites de l’approche. [less ▲]

Motivation – To analyse how Augmented Reality associated to video may affect collaborative design and multimodal interactions. Research approach – An exploratory study that aims to compare 2 pairs of last year students in co-presence with 1 distant pair. Each pair had to solve an architectural design problem. Collected video has been coded with a systematic method of protocol analysis. Findings/Design – When using an AR desktop-based CAD, distance may not affect the design process itself whereas it may affect how the process is distributed across the various modalities of collaboration. Furthermore, collaborating and architectural experiences influence collaboration and/or design. Research limitations/Implications – Only 3 pairs of students participated in the study resulting in 12 h of video protocol, which limits generalisation of the findings. Originality/Value – The research makes a contribution in providing a detailed view on how external (e.g. situation, technology) and individual factors may affect the activity of collaborative design. Furthermore, we propose a coding method usable beyond design in a wide range of collaborative activities to underline how they are affected by technology and other situational constraints. Take away message – Technology constraints as well as personnal characteristics of designers result in designing with specific forms of multimodal collaboration. [less ▲]

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.

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.

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 ▲]
