title A is B, displacement: Exploring linking patterns within metaphor in the design process

summary Design educators often apply metaphor as a teaching tool to help novice designers in their design process. Richards(1936) defines metaphor as the form “A is B”. The most important operation in metaphor is displacement—the linking process of moving A to B. Linking ideas is the key mechanism in the design process. By linking ideas, a graph-like knowledge represents the individual memories with the nodes and arcs that are the ideas and the links between ideas respectively. Such linking knowledge provides an interesting way to understand the operation of displacement within metaphor. This research applies a computational tool (called DIM) to produce a graph-like knowledge. Protocol analysis is then used to understand how designers organize ideas. The objective of this research was to explore the linking patterns of idea displacement within metaphor in the design process.

summary Digital architectures are emerging because of the advancement of information and communication technologies. Rapid prototyping becomes important for digital design in the early conception stage because of the complexity of geometrical relations. The paper is aimed to examine the design teaching issues of dynamic structure by rapid prototyping in experimental studies. Our goal is to integrate the process with rapid prototyping in generating variety types of joints adapting different conditions. This study proposes the digital design process by “playing with parts and joints” approach for the educational purposes. By introducing in design studios, the findings and discussion are reported.

summary This paper contributes to the conference theme by looking at the human impact factors in the context of virtual reality interaction. The creation of architectural design drawings was done through pens and rulers in the beginning. Although the process is time-consuming, the connection of the mind and body is very close and every line drawn are done through the motion of the human body. The development of computer speed up the design process but the generation of the drawings are done with the keyboard and mouse. This human-computer interaction (HCI) disrupted the body-mind connection since the controls are now pointing, dragging and clicking. Architects were having a hard time accustoming to the new methods but gave up to the speed of its efficiency. However, architects never lose their skills to draw and sketch when brainstorming design. The coming of virtual reality (VR) provides an opportunity to bring back this connection. This paper explores the possibilities of human-virtual reality interaction (HVRI) through analysing the currently available VR tools and understand how close they are to this mind-body connection.

summary Fluctuating economies and changing family demographics have increased the complexity in meeting the spatial needs for contemporary housing. Digital systems that allow flexibility are growing in demand but its rate of development is not catching up with the rapid changes. This paper explores how digital interventions can limit or help the process of collaborative design in high-density mass housing context. One key factor in user-oriented design system is participation. Many researchers have looked into system usability, design simplification and realistic visualisation to provide an immersive experience for users to engage the design. This paper argues how gamification acts as a form of decision support within a bigger framework model for a user-oriented digital design system. Using three levels of rules: constitutive rules, operational rules and implicit rules, the aim is for users to generate a housing design outcome not only for themselves but also collaboratively with other users through gamification.

summary Through the lens of participatory mass housing the paper explores the conference theme of simplicity and complexity. A suitable home is a deep rooted desire in the heart of people, and everyone has their own vision of what is a suitable home. Yet the multi-faceted social needs of housing and how they are being designed and developed in mass housing buildings appear too complex and appear too costly that the process would involve direct user participations. The authors have developed a Computer Aided Participatory Housing Design System (CAPHDS) to allow end users (future occupants) become active stakeholders in the design process with the aid of computational design instruments. These tools allow end users to actively engage in the process. The paper describes how a mass housing design process can be broken down into a set of simple tasks that encourage the active engagement and joint development of end users and architects with the proposed design.

title Designing 'Action Trigger' for Architecture Modelling Design within Immersive Virtual Reality
source M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 545-552

summary Architectural modelling is radically evolving with time. The introduction of VR into gaming and education has also encouraged architecture to integrate VR into its course of the design process. However, the current integration of Augmented Reality (AR) and Virtual Reality (VR) components is mostly limited to enhancing visualisation, especially towards the corresponding design tasks. This opportunity lead to an increase in attempts to bring the modelling process into the immersive environment. This paper aims to challenge the current design capabilities within the immersive environment and introduce a new interaction method between the human and the virtual reality. The research in human-computer interaction (HCI) has been ongoing for years till present day to observe how humans interact with computers and design technologies. The appearance of the smartphone has extended this HCI research towards hand-carried devices. With VR, although the hardware is still considered 'computer', the interaction is very much different. Since the human is immersed in the virtual environment, the interaction is already beyond the traditional keyboard and mouse. This paper responds to the conference theme by capitalising the power of VR technology to bring new methods of HVRI to the architecture design process.

title ModRule: A user-centric mass housing design platform
source The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 325.
summary This paper presents a novel platform, ModRule, designed and developed to promote and facilitate collaboration between architects and future occupants during the design stage of mass housing buildings. Architects set the design-framework and parameters of the system, which allows the users to set their space requirements, budgets, etc., and define their desired way of living. The system utilizes gamification methodologies as a reference to promote incentives and user-friendliness for the layperson who has little or no architectural background. This enhanced integration of a both bottom-up approach (user-centric/player) with a top-down approach (architect-centric/game-maker) will greatly influence how architects design high rise living. By bridging the gap between the architect and the user, this development aims to instill a greater sense of belonging to people, as well as providing architects with a better understanding of how to give people more control over their living spaces. The paper also presents an evaluation of a design process that employed ModRule.

title Enhancing Immersion in Virtual Spaces: PhytualBlend - a real-time interaction system for seamless physical feedback
source Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 2, pp. 129–138

summary As an extension of physical space, VR and MR technologies offer convenient solutions for spatial and product design by providing immersive user experiences. Nevertheless, these technologies are limited in their ability to provide physical feedback, which can lead to a perceived disconnection between visual, auditory, and bodily sensations. This paper introduces PhytualBlend, an innovative real-time interaction system designed to enhance the physical feedback experience within virtual environments. The system employs perceptual and executive hardware driven by development boards as its hardware components. User’s operation on physical entities can be synchronized seamlessly to server-based virtual world through a local information hub, including position, orientation, and haptic interaction. Diverse interaction modes within the virtual world trigger corresponding feedback in the physical space, encompassing tactile vibrations, thermal sensations, visual illumination, and object deformations. Our prototypical demonstrates remarkable performance, achieving a frame rate exceeding 60 frames per second with imperceptible network latency. The modular design of PhytualBlend enables efficient and scalable expansion of various physical feedback, interactive modes, and new virtual environments. PhytualBlend bridges the gap between the virtual and physical worlds, enabling remote collaboration participants to experience and interact with virtual contents in a more tangible and realistic manner.

source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary The foreshadowing and transfiguration of architectural space using digital technologies proposes a new order among the physical, symbolic and digital interrelations, where these entities coexist, not only as part of the process that orchestrates thought, but as important mechanisms within the creative process. So we accept that the potentiality of a computerized diagrammatic model expresses more that simply functional aspects, becoming the representation of thought, problems solving and communication, developing images that allow us to explore and to evaluate alternatives, bringing closer objects that we perceive by means of the senses, as well as those that we imagine or dream of.

summary Since March 2020, architecture schools in the world took significant decisions to abandon face-to-face learning; overnight, for security reasons, institutions around the world had to close their doors, confining professors, and students at home to teach online. Education before the Covid-19 pandemic was moving towards digitalization and online teaching, so the emergency exponentially detonated this phenomenon, bringing the Virtual Design Studio (Virtual Design Studio, VDS) as a practical-pedagogical option for distance education. Therefore, defining the concept of Emergency Remote Teaching (ERT). Firstly, the identification and intercession of the previous notions, this work approaches an applicative case with the realization of a workshop, which under the modality Multilevel Workshop -also called Vertical Workshop-, the Faculty of Architecture of the UMSNH proposed to integrate knowledge, skills, and competences under the scheme of Problem Based Learning (PBL).

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 221-228
summary Attempts to address interoperability issues in digital design information have become stilted. A lack of any real success is more indicative of the questions asked rather than the solutions proposed. If design information is the progenitor of design representation, and representation is a method by which to encode, store, and distribute design information, then the issues associated with digital design information can be seen as special cases of the general the problems associated with communication. Considering a representation by asking: ‘What is the information that needs to be communicated?’ and, ‘With whom is this information being communicated?’ may provide a better perspective from which to assess specific technological problems such as software interoperability. The goal of this paper is a call to attention – an exercise in critical thought and a provocation. Can re-conceptualizing the problems with the representation and interoperability of digital design information as generic problems of communication offer insight on novel solutions? A brief overview of the challenges posed to interoperability is presented along with current and past efforts to address this issue. An alternative methodology for the communication of design information via process rather than state descriptions is proposed, followed by a summary conclusion.

summary This paper presents the example of the reconversion of an important tram station from the origins of electricity in Portugal that was still in use until the late 1990’s but became redundant since then. Its significant urban presence and the importance of preserving the memory of the old trams that were still in use some years ago in Lisbon, led to an innovative solution, combining public value and heritage protection. In 2011, the Lisbon City Council agreed to give the building and its site for university use, namely to be transformed into a student’s facility, as a study, leisure, recreational and cultural space of the IST, open 24h a day. This new university building, located just one block away from the traditional IST compound, was called IST Learning Center and extended the notion of campus outside its walls and into the city’s urban fabric.

summary The paper discusses the intersection of two main agendas for Chilean governments that are BIM (Building Information Modeling) and BEAM (Building Environmental Assessment Methods). It shows the state-of-the-art in both fields in Chile as well as in the world, it discusses some previous efforts of integration; it found some new opportunities for collaboration and finally proposes a new framework that brings together BIM and BEAM. The development of the method includes BIM Models, databases and spread sheets for building energy Certification, it finally provides a semi-automatic environment where architects model their design in BIM and this Information is used as an input to the certification process. Potentials and risk of this method are discussed.

summary There is a variety of BIM brands present in the Latin American market, there are several questions about their performance in the Spanish language. BIM software companies with a presence in Latin America were appointed to a series of structured and sequenced workshop. At the end of each talk, a specialized audience responded to a series of structured surveys on both theoretical and practical aspects of the software presented. The demonstration consisted of two areas: one theoretical and one practical. The theory presented relevant historical attributes, brand visibility data and some known examples of its use. In the practical part, a live demonstration of the use of the basic tools and functions of the interface was requested. It was derived that: The companies fulfilled the expectation on the agenda in a dissimilar way, the responses to the surveys revealed a similar performance in general terms (modeling, prices), the workshops showed significant differences in theoretical aspects such as known examples, certification. There is a need to advance in the dissemination of the performance of the different BIM brands in the AEC industry in Latin America, the level of individual experience strongly influences the evaluation of the software, the user's profile and the type of project will determine the software to use.

source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary Our current research is focused on the optimization and evaluation of the architectural building design (gestalt), related and in balance to the inner organization of a building, the floorplan layout. This paper is focused on the impact of Space Layout Planning supported by Information and Communication Technologies (ICT) applied to Architectural Design. We present an overview and wide description of the „architectural design“, the classical definition and methods; and its evolution in practice since the ICT tools impact of the last forty years. Definition such as space program, space relationships, space function are wide discussed to understand the phenomena of architectural layout design, the parameters, variables, constraints and goals of each design. Second we present the state of the art and the current techniques and approaches (optimization, generative systems, artificial intelligence, genetic algorithms, physically based modeling, etc), a classification structure is generated to visualize the areas of impact and use of each technique (different areas from architectural design). Finally we described a complete framework to research and develop our own methodologies based on a specific case of architectural design, the current CAD tools and the possible develop of new tools using the impact of BIM systems.

title Reduce to Understand: A Challenge for Analysis and Three-dimensional Documentation of Architecture
source ENVISIONING ARCHITECTURE: IMAGE, PERCEPTION AND COMMUNICATION OF HERITAGE [ISBN 978-83-7283-681-6],Lodz University of Technology, 23-26 September 2015, pp.388-397
summary For nearly thirty years, the digital phenomenon has integrated many disciplines. Those involved in image processing and analysis took advantage of this major technological breakthrough to revisit the tools and methods of their discipline. In this context, the architectural field, and more specifically the one of heritage analysis and documentation, have greatly benefited from the development of acquisition and visualization techniques. Today, it is no longer unusual to document a building with millions of three-dimensional spatial coordinates. Nevertheless, until the last century, documentation by drawing corresponded to a work of reverse engineering in which it belonged to the architect to understand the object and to represent its key feature. Today, 3D data acquisition technology promotes an increasingly “figurative” representation of architecture. In this paper, we consider some epistemological avenues for the integration of those new approaches to the requirements of architectural representation.
