summary	The digital technology and the integration of knowledge between musicians and architects it’s presented as a unique platform to explore and give a new meaning to the bonds between Music and Architecture. The presentation describes the experience and the results of creative process that link a group of music and architecture students and teachers for a hypermedia composition. The processes are orientated to the simultaneous construction of products from two approaches: from music to the form (plastic or visual), and vice versa. The exploration begins from musical assignments and it’s limited to two types of situations and creative bonds with digital technology: • Independent actions of the subject-musician and subject-architect. • Conjoint actions of both subjects. // The conclusions allow to evaluate the degree of measurability of the process taken care and possible derivations of the particular interpretations of them in each situation.

title	Conjoint Analysis and Virtual Reality - A Review
source	Timmermans (ed.), 4 Ih Design and Decision Support Systems in Architecture and Urban Planning Conference.
summary	This paper describes a review of an ongoing research project which aims to develop a conjoint analysis and virtual reality (CA&VR) system as part of a design information system in virtual reality. The research project aims to develop a design system that can be used for interactive design and evaluation of design alternatives. A virtual environment model and dynamic virtual objects representing the different design aspects of interest can present a design. The different design aspects are called attributes. Each attribute level is a different state of the concerned virtual object. In the case of a virtual walk through a building design, the system can be viewed as a visual simulation of the environment. The CA&VR system has the potential advantage that individuals' preferences can be measured in designed hypothetical choice situations. As part of the ongoing research project, principles underlying the CA&VR system will be illustrated by simple examples. The status of this research project, both in retrospect and in prospect will be described.

title	The Application of Conjoint Measurement as a Dynamic Decision Making Tool in a Virtual Reality Environment
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 757-770
summary	This paper describes an innovative aspect of an ongoing research project to develop a virtual reality based conjoint analysis system. Conjoint analysis involves the use of designed hypothetical choice situations to measure subjects' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Hypothetical alternatives, called product profiles, are generated and presented to subjects. A virtual reality presentation format has been used to represent these profiles. A profile consists of a virtual environment model and dynamic virtual objects representing the attributes with their respective levels. Conventional conjoint choice models are traditionally based on preference or choice data, not on dynamic decision making aspects. The status of this new approach will be described.

title	Exploring the Possibilities of Conjoint Measurement as a Decision-Making Tool for Virtual Wayfinding Environments
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 61-71
summary	Virtual reality systems may have a lot to offer in architecture and urban planning when visual and active environments may have a dramatic impact on individual preferences and choice behaviour. Conjoint analysis involves the use of designed hypothetical choice situations to measure individuals’ preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives, called product profiles, are generated and presented to respondents, who are requested to express their degree of preference for these profiles or choose between these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of production profiles. Virtual reality systems offer the potential of moving the response format beyond these traditional response modes. This paper describes a particular aspect of an ongoing research project which aims to develop a virtual reality based system for conjoint analysis. The principles underlying the system will be illustrated by a simple example of wayfinding in a virtual environment.

summary	Conjoint analysis (also called stated preference analysis) involves the use of designed hypothetical choice situations to measure individuals' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives (product profiles) are generated and presented to respondents, who are requested to express their degree of preference for these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of product profiles. This paper describes a framework for a conjoint analysis system in a virtual environment. Product profiles are generated in a virtual environment and respondents are requested to choose in that virtual environment the product profile they prefer. Advantages of a virtual environment in this area of research include 3D presentation, improved experience and the possibility to include measurable attributes such as time and sound. This framework is a first attempt to explore the possibilities of virtual reality systems in conjoint analysis.

title	Measuring user satisfaction for design variations through virtual reality
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper describes Virtual Reality as an environment to collect information about user satisfaction. Because Virtual Reality (VR) allows visualization with added interactivity, this form of representation has particular advantages when presenting new designs. The paper reports on the development of a VR system that supports architects to collect opinions about their design alternatives in terms of user preferences. An alternative to conjoint analysis, that uses statistical choice variations to estimate user preference functions, is developed. Artificial Intelligence (AI) Agent technology will be implemented to build a model for data collection, prediction, and learning processes.

title	Towards A Decision Support System for the Planning, Design and Maintenance of Urban Green Space
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	As one of the domains of urban planning and design, that of green space is lagging behind in terms of the use of advanced computer technology, mo dels and design methodology compared to, for example, retail and transportation planning. However, recently, there is some evidence of the development and testing of tools such as visualization, GIS and conjoint analyses in this area, although not of more integrated Decision Support Systems. The purpose of this study is to outline ideas and needs for thedevelopment of a Decision Support System for the planning and design of green space. The objective is to provide planners with an integrated framework for the provision and management of these parts of urban areas.

title	Measure the Evacuees’ Preference on ArchitecturalCues by CAVE
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	An evacuees’ preference prediction function on architectural cues are described here as a crucial part of the evacuation model to simulate how the evacuees search the route to exit according to the architectural information in the public underground space. The model is developed to evaluate the egress design in the initial space design stage and to provide the existing compositive evacuation models a support on the usage of architectural information. First the over simplification on the architectural information in the existing evacuation models is discussed. Then a list of so-called architectural cues and the related evacuation model are introduced, in which the evacuees always egress to the seen or remembered architectural cue with the highest preference in every step. The emphasis of the paper is put on the analysis of the preference function including the CAVE-based conjoint analysis research method, the experiment design and implementation of the virtual drill, and the estimation of the parameters from the collected choices. The preference function for five architectural cue pairs, Doorway-Doorway, Stair-Stair, Exit- Exit, Doorway-Stair, Exit-Stair is built from the choice data of nearly one hundred Chinese subjects.

title	Conjoint Approaches to Developing Activity-Based Models
source	Eindhoven University of Technology, Faculty of Architecture and Urban Planning, The Netherlands
summary	Since the late 1950s, transportation models have played an important role in forecasting travel demand and evaluating the impacts of plans and policies. Planners use transportation models to learn about the behavior of transport systems. Over the past decades, the development of particular modeling approaches has closely followed planning needs, which in turn are closely related to dominant policy issues. The first generation of transportation models was developed during the late 1950s and early 1960s. Their purpose was to facilitate the prediction of future travel demand, such that road capacity programs could be based on predicted demand. The first generation models are commonly referred to as four-step models. These models are typically formulated and calibrated at the level of the traffic zones. Individuals are aggregated by traffic zone. Traffic is considered to be the result of four sequential decisions: trip generation, trip distribution, modal split and traffic assignment. These decisions are modeled separately at successive stages. Although the four-step models have been widely used, even institutionalized in literally thousands of applications (Stopher, et al., 1996), the major shortcoming of these large-scale, aggregate and supply-oriented models is their lack of behavioral content.
