The purpose of this article is to study the 3D model design and interactive experience optimization strategy of cultural creativity product CAD (computer aided design) based on VR (virtual reality) technology, improve the accuracy and recall rate of cultural creativity's product image feature detection, and locate the edge contour of the product image relatively accurately. Therefore, an optimization method of 3D modeling of cultural creativity products based on generative antagonism network (GAN) is proposed. The performance of this algorithm and the layout optimization algorithm based on convolutional neural network (CNN) are compared through experiments. Experimental show that, compared with the layout optimization algorithm based on CNN algorithm, the accuracy of the proposed algorithm is improved by more than 20%, and the recall rate is also significantly improved. Moreover, the algorithm can also protect the detailed features of cultural creativity products, making the applications of 3D reconstruction and virtual display of cultural creativity products more accurate and reliable. Through deep learning and special optimization strategies, the algorithm can identify and locate the key features of products more accurately, thus playing an important role in product quality control, detail repair and digital protection. In addition, the algorithm can also be applied to other areas of 3D image feature detection and related application research, which has certain theoretical significance and practical application value. © 2024 U-turn Press LLC, http://***.

design Thinking: Standing on the Shoulders of… Graphic design!

design ISSUES 2024年第3期40卷 49-61页

作者： Harland, Robert Meron, Yaron Urban Graphic Heritage at Loughborough University's School of Design and Creative Arts United Kingdom University of Sydney's School of Architecture Design and Planning Australia

Prominent design discourse or advocacy in the domain of "design thinking" rarely depicts graphic design consistently or with sufficient rigor and understanding about the field's role in the development of design studies. Nor do most advocates for graphic design proffer it to be little more than a vernacular activity when competing for academic attention, despite its widespread academic presence, industry prominence, and everyday practice. The arguments presented here offer a timely critical perspective on a frequently unchallenged prevailing discourse that has echoed consistent assumptions over several decades. We call for more integrity in respect for those who design in different communication contexts, more precision in discussing how graphic design has evolved and been portrayed, and more rigor in the thoroughness and care that research into graphic design and its associated fields demands. The outcomes will be of particular interest to researchers who draw on and re-present Buchanan's four orders of design concept and offer an alternative perspective to those who suggest graphic design relies overly on intuition when deliberating on design thinking.

Concurrent Engineering Research and Applications 2023年第1-2期31卷 49-63页

Quality function deployment (QFD) is a systematic approach to transform customer requirements (CRs) into product engineering characteristics (ECs). Traditional QFD relies on market research or customer questionnaires to collect a series of ambiguous and uncertain CRs. As a result, evaluating the weighting of CRs and determining the design matrix between CRs and ECs have become the focus and difficulty of QFD. This paper proposes the grey system theory in artificial intelligence technology combined with QFD to develop grey-QFD to solve the issues mentioned before. First, collect the average evaluation values between the aesthetic images and customer satisfaction of representative products. The grey prediction GM (1, N) model is used to obtain the weight of aesthetic needs relative to customer satisfaction and import it into the left QFD. Second, the domain experts decomposed the product form into a morphological analysis table, and fuzzy Delphi screened key ECs and imported them into the ceiling of QFD. Finally, grey relationship analysis established the aesthetic product design matrix between CRs and ECs, and calculated and ranked the final weights of each ECs by using grey relationship degree. The research uses the security camera in the smart home as an experimental object. After operating the proposed grey-QFD, the aesthetic quality of the target product (lively, intelligent, friendly, personalized, and fashionable) and the optimization of the corresponding product ECs are obtained. The result provides a theoretical reference for designers and significantly improves customer aesthetic satisfaction. © The Author(s) 2023.

学位级别：博士

designing tools for performing safety-critical work tasks is demanding engineering discipline. Numerous highly specialized engineering knowledge needs to be integrated to create a well-functioning design solution that appropriately serves carrying out the work and fulfilling the goals of the activity. The design task of this magnitude goes easily beyond the capabilities of an individual designer. Consequently, representing a considerable collaboration challenge to the design process. Expert users (e. g., process control operators) are a group of specialists that could potentially contribute much to developing the appropriate solutions. Many industrial standards also demand acknowledging the end user perspective in design. However, the expert users' role in the context of safety-critical design, have conventionally been restricted to involving the users in the later evaluation phases. At the same time, at these later stages, there may only be remote possibilities to make any radical changes to the design regarding the identified needs by the expert users. Yet, the tools are an integral part of the safety-critical system and the sensitivity that relates to the ability of expert users to operatively master their tools should not be forgotten. From the overall safety perspective, it is also highly relevant how the expert users know and use their tools. Therefore, this thesis aims to promote early expert user involvement in design of safety-critical systems and thus enable better inclusion of their hands-on experience and wealth of operative knowledge in design. The expert users should be involved in at the early stage of the design and the participation of the expert users should continue throughout the design process and the lifecycle of the system. This thesis presents the development of method which facilitates participative processes and enables involving the expert users in safety-critical system design. The functional modeling of Tools-in-Use (TiU) is introduced i

I Feel You is a speculative textile design project looking into the possibilities to create multi-sensory electronic textiles that imitate living beings. The theme of textile surfaces imitating living beings has emerged from yearning for touching and closeness: During the global pandemic and the ongoing wave of extinction, I imagined a world where we are increasingly physically separated from each other and other animals. What if, in the future, we are accompanied by robot pets and people? Against this backdrop, this work speculates on how textiles could create an illusion of being close to another living being and being touched by a living creature. The series of textile pieces consists of Jacquard woven multilayered textiles that, when combined with electronics, react to the human touch. The materials include linen, cotton, responsible mohair, wool, and silver-based electrically conductive threads. Together and separately the materials and woven structures strive to create multisensory, touchable worlds. The aim of the study was to discover what kinds of textile surfaces humans can identify through the sense of touch, what kind of touch is experienced as soothing, and how to bring reactivity that imitates living beings into woven textiles. This knowledge was used as a basis to create a series of speculative woven electronic textile pieces that react to touch. Traditional materials and techniques interweave with new technologies creating possibilities to design new types of interactions with textiles. When designing active haptic textile surfaces, traditional properties of textiles, such as materials, patterns, and woven structures cannot be separated from the design process, where all the aspects entangle and affect each other. © 2023 Owner/Author.

The concept that technology should be designed iteratively is a well-established tenet in participatory design. However, iteration has received insufficient attention regarding how and why we should also evolve tools that support participatory processes. Based on empirical material from five participatory renewable energy projects conducted in different school communities, this paper documents how a seemingly mundane participatory design tool, a paper template, evolves through iteration to better scaffold collaborative design work. We show how iteration has implications for the overall direction of the project towards sustainability by surfacing future issues. The templates allowed a collective move from designing a renewable energy generator towards making a school collective for sustainable use, management, and adjustment of the generator they built. The iterations illustrate how participatory design tools can collect mundane things relevant for design decisions and how such things can be translated at higher levels. © 2024 Owner/Author.

This paper presents a case study integrating generative design and bamboo culm geometries. Our goal is to improve the application of biological materials in a responsive Computer-Aided design (CAD) process. We argue that fabrication-aware design tools are currently inadequate because they do not embed intrinsic biological geometrical properties into the design or fabrication processes. Although research with CAD tools has advanced the development of generative and fabrication-aware design processes for the built environment, most of these tools are developed for off-the-shelf materials that are typically unitized, industrialized, and homogeneous. This has made it difficult to find and create computational tools for naturally variable biological materials. While employing eccentric biological materials such as bamboo imposes an added layer of complexity on the design-to-fabrication process, it may also offer more sustainable material application and expand the frontiers of design and fabrication research methods. The methods explored in this paper are deployed to realize freeform Nexorade structures (FNS) that are explicitly tailored to individual bamboo culms (BC);each of these has been measured to explore the potential that material eccentricity may be a district benefit rather than a detriment to the quality and efficiency of a design. © 2023 Hybrids and Haecceities - Proceedings of the 42nd Annual Conference of the Association for Computer Aided design in architecture, ACADIA 2022.

Latent Dirichlet Allocation (LDA) topic models for Space Syntax studies on spatial experience

引用

City, Territory and architecture 2024年第1期11卷 3页

作者： Lee, Ju Hyun Ostwald, Michael J. School of Built Environment Faculty of Arts Design and Architecture The University of New South Wales Sydney 2052 NSW Australia

Spatial experience has been extensively researched in various fields, with Space Syntax being one of the most widely used methodologies. Multiple Space Syntax techniques have been developed and used to quantitively examine the relationship between spatial configuration and human experience. However, due to the heterogeneity of syntactic measures and experiential issues in the built environment, a systematic review of socio-spatial topics has yet to be developed for Space Syntax research. In response to this knowledge gap, this article employs an ‘intelligent’ method to classify and systematically review topics in Space Syntax studies on spatial experience. Specifically, after identifying 66 articles using the ‘Preferred Reporting Items for Systematic reviews and Meta-Analyses’ (PRISMA) framework, this research develops generative probabilistic topic models to classify the articles using the Latent Dirichlet Allocation (LDA) method. As a result, this research automatically generates three architectural topics from the collected literature data (A1. Wayfinding behaviour, A2. Interactive accessibility, and A3. Healthcare design) and three urban topics (U1. Pedestrian movement, U2. Park accessibility, and U3. Cognitive city). Thereafter it qualitatively examines the implications of the data and its LDA classification. This article concludes with an examination of the limitations of both the methods and the results. Along with demonstrating a methodological innovation (combining PRISMA with LDA), this research identifies critical socio-spatial concepts and examines the complexity of Space Syntax applications. In this way, this research contributes to future Space Syntax research that empirically investigates the relationships between syntactic and experiential variables in architectural and urban spaces. The findings support a detailed discussion about research gaps in the literature and future research directions. © 2024, The Author(s).
