Developing a Framework for Heterotopias as Discursive Playgrounds: A Comparative Analysis of Non-Immersive and Immersive Technologies

The discursive space represents the reordering of knowledge gained through accumulation. In the digital age, multimedia has become the language of information, and the space for archival practices is provided by non-immersive technologies, resulting in the disappearance of several layers from discursive activities. Heterotopias are unique, multilayered epistemic contexts that connect other systems through the exchange of information. This paper describes a process to create a framework for Virtual Reality, Mixed Reality, and personal computer environments based on heterotopias to provide absent layers. This study provides virtual museum space as an informational terrain that contains a "world within worlds" and presents place production as a layer of heterotopia and the subject of discourse. Automation for the individual multimedia content is provided via various sorting and grouping algorithms, and procedural content generation algorithms such as Binary Space Partitioning, Cellular Automata, Growth Algorithm, and Procedural Room Generation. Versions of the framework were comparatively evaluated through a user study involving 30 participants, considering factors such as usability, technology acceptance, and presence. The results of the study show that the framework can serve diverse contexts to construct multilayered digital habitats and is flexible for integration into professional and daily life practices

Game-like interactive environment using BIM-Based Virtual Reality for the Timber Frame Self-Build Housing Sector

BIM, gamification, and Virtual Reality applications are more often used to serve the interests of Design for Manufacture and Assembly (DfMA). This paper presents a comprehensive study to exploit these technologies’ innovative approaches and capabilities. The study is specifically adopted to implement small and medium-size architectural and construction practices with a limited budget and time dedicated to visualisation creation. The collected evidence proved that a game-like platform combined with BIM could provide simplified data delivery to a client, leading to customer satisfaction, confidence and increased sales. The designed workflow and templates were tested in the case study of a small self-build construction company. The staff was trained to provide BIM data correctly and use supplied game templates. The case study demonstrated that automation of the VR House Configurator creation is achievable. The study’s outcome is an integrated solution to regenerate BIM models in the game environment and utilise the house configurator’s organised furniture library and costing interface. Furthermore, the usability tests confirmed the applicability, practicability, and validity of the developed framework and tools to deal with the revealed challenges in the self-build sector. Finally, the research provided a fresh approach for the companies in the sector, a step-by-step guide for implementing the innovative changes, and detailed descriptions of the methodologies and workflows

London is a globally recognised hub for technology, design and creative genius. While many cities around the world can claim to be hubs for technology entrepreneurship, London’s distinctive potential lies in the successful fusion of world-leading technology with world-leading design and creativity. As innovation thrives at the edge, where better to innovate than across the boundaries of these two clusters and cultures? This booklet tells the story of Fusion’s innovation journey, its partners and its unique business support. Most importantly of all it tells stories of companies that, having worked with London Fusion, have innovated and grown. We hope that it will inspire others to follow and build on our beginnings.European Regional Development Fund 2007-13

Virtual reality for the built environment: A critical review of recent advances

This paper reviews the current state of the art for Virtual Reality (VR) and Virtual Environment (VE) applications in the field of the built environment. The review begins with a brief overview of technological components involved in enabling VR technology. A classification framework is developed to classify 150 journal papers in order to reveal the scholarly coverage of VR and VE from 2005 to 2011, inclusive. The classification framework summarizes achievements, established knowledge, research issues and challenges in the area. The framework is based on four layers of VR: concept and theory, implementation, evaluation and industrial adoption. These layers encompass architecture and design, urban planning and landscape, engineering, construction, facility management, lifecycle integration, training and education. This paper also discusses various representative VR research work in line with the classification framework. Finally the paper predicts future research trends in this area

IM-sgi an interface model for shape grammar implementations

This research arises from the interest in computing as offering new paradigms in the design practice. Information technologies are the driving force for progress in the processes of design, enabling new forms of creativity. The increasing sophistication of computer applications, their easier access, and lower cost have had a significant impact on design practices and can be regarded as a paradigm shift. The invention and creativity are thus seen as knowledge processing activities and can, at least partially, be carried out with the support of computer applications. In this context Shape Grammars (SG) as production systems of designs through rules have the potential to create designs with variable user input and the ability to evaluate a large number of alternatives that may lead to innovative designs. Most architects and designers use computers on their daily practice as a representation tool for their projects, but not as a facilitator or increaser of the creative process. SG computational implementations have the potential to enhance creativity with the test of a wide range of design options, helping the appearance of new solutions, either through the emergence of new shapes or by stimulating the designer’s creativity with the possibilities presented. As Architects and Designers haven't adopted existing SG computational implementations, that take advantage of computation to facilitate and enhance their work, could the problem be on the communication between the applications and the user? If the interface of the SG implementation does not allow the user to understand how to use it or how to control and make use of its results, it can’t be successfully used. With interest in SG implementations as creative partners in the creative process, our research starts with the analysis of existing SG implementations, trying to understand if they had the potential to be adopted by architects and designers in their practice and, if not, what could be done to lead to that objective. User Interface Inspection Methods were used to perform this analysis and allowed us to understand that there are interactions and communication issues that need to be addressed for SG implementations to be adopted by designers. Taking this direction, we understood that models of interaction between the user and SG implementations have already been developed. The present research proposal started from the analysis of the interaction model of Scott Chase, where he defines the different levels of interaction between the user and SG implementation, with more or less input from the user, establishing different ways to combine synergies to obtain new creative solutions. Taking this interaction model as a starting point, next, we must assure the correct communication between user and implementation occurs. The means of communication between these two agents is the computational interface. Understanding the importance of the interface to allow the user to know how to use the computational implementation and be able to produce results, our research presents the development of an interface model for SG implementations to help to take a step towards the adoption of SG for creative projects. For this, we used methods from Human-Computer Interaction discipline, and we also took Bastien & Scapin's "List of Ergonomic Criteria Guidelines" as guiding lines to define the Criteria of our interface model, called IM-sgi, Interface Model for Shape Grammar Implementations. Thus, IM-sgi, an interface model for SG Implementations, has the purpose of helping SG implementations developers to address the interface on the right path to a correct communication with the particular type of user that architects and designers are. Interface prototypes following IM-sgi criteria are finally developed and presented to test the suitability of the IM-sgi Model to SG implementations and validate the objectives we propose.A presente pesquisa surge do interesse na computação por oferecer novos paradigmas na prática do design. As tecnologias da informação são a força motriz para o progresso nos processos de design, permitindo novas formas de criatividade. A crescente sofisticação das aplicações computacionais, o acesso mais fácil às mesmas e menor custo associado tiveram um grande impacto nas práticas de projeto e podemos considerar estar perante uma mudança de paradigma. A invenção e a criatividade são, portanto, vistas como atividades de processamento de conhecimento e podem, pelo menos parcialmente, ser realizadas com o suporte do computador. Nesse contexto, As Gramáticas de Forma, como sistemas de produção de designs através de regras, têm o potencial de criar projetos com entradas com níveis variáveis de intervenção do utilizador e apresentam a capacidade de avaliar um grande número de alternativas que podem levar a designs inovadores. A maioria dos arquitetos e designers usa o computador na sua prática diária como uma ferramenta de representação para seus projetos, mas não como um facilitador ou potenciador do processo criativo. As implementações computacionais de Gramáticas de Forma têm o potencial de aumentar a criatividade com o teste de uma ampla gama de opções de design, ajudando no surgimento de novas soluções, seja pela emergência de novas formas ou estimulando a criatividade do designer com as opções desenvolvidas. Uma vez que as implementações computacionais de Gramáticas de Forma existentes não foram adotadas por Arquitetos e Designers, que claramente tiram proveito de aplicações computacionais para facilitar e aperfeiçoar o seu trabalho, poderá o problema estar na comunicação entre as implementações e o utilizador? Se a interface da implementação não permitir que o utilizador entenda como usá-la ou como controlar e utilizar os seus resultados, ela não poderá ser utilizada com sucesso. Com interesse nas implementações de Gramáticas de Forma como parceiros criativos no processo criativo, a nossa investigação começa com a análise das implementações de Gramáticas de Forma existentes, tentando entender se estas têm potencial para ser adotadas pelos criativos na sua prática e, se não, o que poderia ser feito para chegar a este objetivo. Foram usados métodos de inspeção para realizar esta análise para nos permitir compreender que há interações e problemas de comunicação que precisam de ser resolvidos para que as implementações de Gramáticas de Forma sejam adotadas pelos projetistas. Seguindo essa direção de investigação, percebemos que foram já desenvolvidos modelos de interação entre o utilizador e as implementações de Gramáticas de Forma. A presente proposta de pesquisa surgiu a partir da análise do modelo de interação de Scott Chase, onde este define os diferentes níveis de interação entre utilizador e implementação de Gramáticas de Forma, com maior ou menor input do utilizador, estabelecendo diferentes formas de combinar sinergias para obter novas soluções criativas. Tomando esse modelo de interação como ponto de partida, devemos assegurar que a comunicação correta entre o utilizador e a implementação ocorra. O meio de comunicação desses dois agentes é o interface computacional. Entendendo a importância do interface para permitir que o utilizador entenda como usar a implementação computacional e seja capaz de produzir resultados, a nossa pesquisa apresenta o desenvolvimento de um modelo de interface para implementações de Gramáticas de Forma para ajudar a dar um passo na direção da adoção das Gramáticas de Forma para projetos criativos. Deste modo, aplicámos métodos da disciplina de HCI e também adotámos a Lista de Diretrizes e Critérios Ergonómicos de Bastien & Scapin como linhas de orientação para definir os Critérios do nosso modelo de interface, denominado IM-sgi. O IM-sgi, um modelo de interface para Implementações de Gramática de Forma, tem a finalidade de ajudar programadores de implementações de Gramáticas de Forma a endereçar a interface no sentido de atingir uma comunicação correta com o tipo particular de utilizador que são os arquitetos e designers. Protótipos de interface seguindo os critérios IM-sgi são finalmente desenvolvidos e apresentados para testar a adequação do modelo IM-sgi e validar os objetivos que propomos

3D assistive technologies and advantageous themes for collaboration and blended learning of users with disabilities

The significance of newly emergent 3D virtual worlds to different genres of users is currently a controversial subject in deliberation. Users range from education pursuers, business contenders, and social seekers to technology enhancers and many more who comprise both users with normal abilities in physical life and those with different disabilities. This study aims to derive and critically analyze, using grounded theory, advantageous and disadvantageous themes and their sub concepts of providing elearning through 3D Virtual Learning Environments (VLEs), like Second Life, to disabled users; hence providing evidence that 3DVLEs not only support traditional physical learning, but also offer e-learning opportunities unavailable through 2D VLEs (like moodle, blackboard), and offer learning opportunities unavailable through traditional physical education. Furthermore, to achieve full potential from the above mentioned derived concepts, architectural and accessibility design requirements of 3D educational facilities proposed by different categories of disabled students to accommodate for their needs, are demonstrated

Design prototyping methods

textProduct development is often modeled as a cycle between phases of designing, building, and testing. This work will explore early stage build efforts of product design, which is also known as prototyping. Prototyping is a critical determinant of product success. Research shows that different approaches to prototyping can greatly affect design outcome. This work provides an integrated overview, and expansion of the existing work on design prototyping methods. Following the introduction, an extensive literature review of design prototyping tools, techniques, and methods is provided. These sources are indexed and comparatively reviewed. The capabilities of a novel hybrid prototyping technique is explored through a design case study. Next, insights from the review are integrated in a context independent prototyping strategy method. The method is developed with heuristics extracted from the literature, and additional insights from experimental studies. The technique is then experimentally evaluated. Finally, results of an extensive study of an online design repository are provided. The results include five key principles for prototype design and fabrication. The presence of these principles in the repository is validated through a novel crowd-sourced online study. The outcome effects of deploying these principles to design teams is experimentally evaluated. Overall, this research provides a guide to prototyping which includes a systematically indexed review and comparison of the existing work, as well as a novel method, and principles for design and fabrication.Mechanical Engineerin
