Multimedia and Knowledge-based Computer-aided Architectural Design

It appears by now fairly accepted to many researchers in the field of the Computer Aided Architectural Design that the way to realize support tools for these aims is by means of the realization of Knowledge Based Assistants. This kind of computer programs, based on the knowledge engineering, finds their power and efficaciousness by their knowledge bases. Nowdays this kind of tools is leaving the research world and it appears evident that the common graphic interfaces and the modalities of dialogue between the architect and the computer, are inadequate to support the exchange of information that the use of these tools requires. The use of the knowledge bases furthermore, presupposes that the conceptual model of the building realized by others, must be made entirely understandable to the architect . The CAAD Laboratory has carried out a system software prototype based on Knowledge Engineering in the field of hospital buildings. In order to overcame the limit of software systems based on usual Knowledge Engineering, by improving architect-computer interaction, at CAAD Lab it is refining building model introducing into the knowledge base two complementary each other methodologies: the conceptual clustering and multimedia technics. This research will make it possible for architects navigate consciously through the domain of the knowledge base already implemented

The role of boundary objects in the co-evolution of design and use: the KMP project experimentation

Nowadays, it is widely recognized that an ICT tool cannot be built without knowing who will use it and what they will do with. In this perspective, Human-Computer Interaction community (Carroll, 1990; Jarke, Tung Bui and Carroll, 1998; Young and Barnard, 1987; Young and al., 1989) developed a scenario-based approach contrasting with the traditional information system design. The scenario describes an existing or envisioned system from the perspective of one or more users and includes a narration of their goals, plans and reactions (Rosson and Carroll, 2002). As a result, design is founded on the use of scenarios as a central representation for the analysis and design of use. The scenario-based design appears to be a first step in the integration of users in the design of ICT tool. However, we would like to underline in this paper a more active role of users in the design process. According to Orlikowski (2000) while a technology can be seen to have been constructed with particular materials and inscribed with developers' assumptions and knowledge about the world at a point in time, it is only when this technology is used in recurrent social practices that it can be said to structure user's action. The use of technology in recurrent social practices must be considered because how technological properties will for the moment be used or appropriate is not inherent or predetermined. Finally, this approach leads us to dissociate the designers' world from the users' world. In this perspective, the design project is the result of the co-evolution and the convergence of both worlds: on the one hand, the world of design and a first integration of users by scenarios; on the other hand, the world of users where innovation is the art of interesting an increasing number of allies who will make the world of design stronger and stronger. The objective of this paper is to understand the mechanisms of interaction between the world of design and that of users i.e. between loops of co-design and loops of uses. Indeed, according to Akrich, Callon and Latour (1988) we adopt a whirlwind model of innovation. In this perspective, “innovation continuously transforms itself according to the trials to which it is submitted i.e. of the “interessements” tried out » (Akrich and al., 2002: 7). We will demonstrate that the key success of an innovation depends on the co-evolution and convergence of design and use around boundary objects developed during this process (see Figure 1). More specifically, we will show the role of boundary objects on the integration and on the involvement of users in the design process. In order to do so, we carried out an empirical research – the Knowledge Management Platform project - located in the scientific park of Sophia Antipolis (Alpes-Maritimes, France), focusing on the Telecom Valley® (TV) association which gathers the main actors of the Sophia Antipolis Telecom cluster. Indeed, the KMP project aims to build a semantic web service of competencies in order to enhance exchange and combination dynamics of knowledge within the Telecom cluster thanks to an interactive mapping of competencies. This paper will comprise three parts: Based on the researches of Akrich, Callon and Latour (1988), Hatchuel and Mollet (1986), Orlikowski (2000), Romme and Endenburg (2006) we will identify and analyse in a first part the process of design. The combination of these approaches leads us to distinguish the design' world from the users' world. In this perspective, the success of an innovation may be explained by the co-evolution and the convergence of these two worlds. In this process, we suggest that boundary objects play a key role in the convergence of these two worlds. We will present in a second part the empirical study of the KMP project within the TV network. The KMP project involved researchers from socio-economic sciences (GREDEG Laboratory, UNSA-CNRS, Rodige and Latapses teams), cognitive sciences and artificial intelligence (INRIA, Acacia team), telecommunications (GET) and users (TV) for a total force of 187 men per month for a two-year period (2003-2005). At this present time this project is being set up in a pre-industrialization phase, supported by TV and the PACA region. Here, we will analyse the specific process of design experimented by KMP. Finally, the third part discusses the role of boundary objects in the KMP experimentation. In this part, we will show the evolution of boundary objects during the loops of design. More specifically, the focus will be on the emergence of compromises between designers and users, their materialisation in boundary objects and finally their evolution during the design' process.boundary objects, IS development, actor network theory

Research Project as Boundary Object: negotiating the conceptual design of a tool for International Development

This paper reflects on the relationship between who one designs for and what one designs in the unstructured space of designing for political change; in particular, for supporting “International Development” with ICT. We look at an interdisciplinary research project with goals and funding, but no clearly defined beneficiary group at start, and how amorphousness contributed to impact. The reported project researched a bridging tool to connect producers with consumers across global contexts and show players in the supply chain and their circumstances. We explore how both the nature of the research and the tool’s function became contested as work progressed. To tell this tale, we invoke the idea of boundary objects and the value of tacking back and forth between elastic meanings of the project’s artefacts and processes. We examine the project’s role in India, Chile and other arenas to draw out ways that it functioned as a catalyst and how absence of committed design choices acted as an unexpected strength in reaching its goals

The (New) roles of prototypes during the co-development of digital product service systems

This paper investigates different roles that prototypes play during the development of digital Product Service Systems (PSSs). A literature review reveals that prototyping supports designers during the design process, as well as during knowledge sharing processes with stakeholders. To create a better understanding of these two co-existing roles of prototyping, we executed a research-through-design project in the healthcare domain. This design project was centred around the development of four different prototypes that the designer sequentially developed. A major input into the design process was co-reflection sessions between the designer and different stakeholders. We analysed the prototyping process and the co-reflection sessions. Moreover, we executed a conversational analysis to understand the actual knowledge sharing processes between the designer and the different stakeholders. The results present a detailed overview of the different (co-existing) roles of the prototypes. We distinguished two new types of prototypes which were both related to the development of the intangible aspects of the digital PSS: (1) service interface prototrial aimed at exploring several options for detailing the different intangible aspects of the digital PSS, and (2) service provotype to stimulate collaborative creation of the intangible aspects of the digital PSS in an early stage

This report describes the data collection and requirements analysis effort of the Ground System Development Environment (GSDE) Interface Requirements study. It identifies potential problems in the interfaces among applications and processors in the heterogeneous systems that comprises the GSDE. It describes possible strategies for addressing those problems. It also identifies areas for further research and prototyping to demonstrate the capabilities and feasibility of those strategies and defines a plan for building the necessary software prototypes

Electronic prototyping

The potential benefits of automation in space are significant. The science base needed to support this automation not only will help control costs and reduce lead-time in the earth-based design and construction of space stations, but also will advance the nation's capability for computer design, simulation, testing, and debugging of sophisticated objects electronically. Progress in automation will require the ability to electronically represent, reason about, and manipulate objects. Discussed here is the development of representations, languages, editors, and model-driven simulation systems to support electronic prototyping. In particular, it identifies areas where basic research is needed before further progress can be made
