title	Digital Application of Typo-morphology in the Conservation and Renewal of Historic Areas
doi	https://doi.org/10.52842/conf.caadria.2023.1.545
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 545–554
summary	The conservation and renewal of historic areas are facing many complex and scattered problems, which are not suitable to be completed by a unified method. Designers tried to use the typo-morphology to analyse the morphology of each micro unit to carry out targeted conservation and renewal actions. However, any adjustment of spatial structure may affect the morphological characteristics of the whole block and each micro unit, designers need an efficient method to control the dynamic changes of the block in real-time. Based on the hierarchical structure of typo-morphology, a digital model of the historic areas was built. This model can be perfected as a morphological analysis tool and analyse the block's spatial morphological evolution during its conservation and renewal process. In the renewal design work of Hehuatang historical and cultural block in Nanjing, this method helps designers test each strategy's rationality and find a more scientific scheme to guide the further detailed design. The involvement of digital methods enables typo-morphology to assist design work more accurately and promote the working mode to gradually change from "experience-based artificial induction" to "data-based pattern extraction".

title	Four-Dimensional Printing on Textiles Evaluating Digital File-to-Fabrication Workflows for Self-Forming Composite Shell Structures
doi	https://doi.org/10.52842/conf.ecaade.2023.1.491
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 491–498
summary	This design-led research investigates the development of self-forming wearable composite structures by printing embossed patterns out of flexible filament on pre-stretched textiles and releasing the stress after the printing has been completed, whereby time becomes the fourth dimension of the printing process. In particular, the study presents and compares three methods of ‘file-to-fabrication’ techniques for generating self-forming textile shell structures: The first is based on modified geometrical patterns in relation to curvature analysis, the second on printed patterns related to their stress line simulation and the third on an analysis of the anisotropic shrinking behaviour of stripe patterns. The findings emphasize the advantages and challenges of each method as well as present a comparative table chart highlighting the relationship between material properties, pattern geometry and the formal vocabulary of the composite shells.

title	Urban Fabric Generation: A comparative analysis of multiple vector field methods
doi	https://doi.org/10.52842/conf.ecaade.2023.1.721
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 721–730
summary	This paper provides a comparative analysis of vector field methods for automatically generating urban fabric geometries and introduces the Rhino/Grasshopper plugin UrbanFab which implements these methods. Automated generation of urban design is a growing area of research addressing the complex challenge of building sustainable and economically viable cities. Within this research area vector fields are used to generate non-uniform urban fabric geometries. Similar to simulation of magnetic fields or moving fluids, vector field algorithms can be adapted to simulate urban sites, resolving complex site constraints and generating geometry used in the design of roads, land parcels or buildings. Vector field methods for urban fabric generation, however, are not well represented in computational tools serving urban designers, or in description of algorithms and evaluations in computational urban design literature. To address these challenges, this paper describes multiple urban vector field algorithms, with accompanying streamline visualization and evaluation methods. A comparative analysis of the results generated by these methods provides a means for designers to make informed decisions on which method is appropriate to their requirements and supports discussion of future work in urban fabric generation.

title	The evaluation of urban spatial quality and utility trade-offs for Post-COVID working preferences: a case study of Hong Kong

summary	The formation of urban districts and the appeal of densely populated areas reflect a spatial equilibrium in which workers migrate to locations with greater urban vitality but diminished environmental qualities. However, the pandemic and associated health concerns have accelerated remote and hybrid work modes, altered people's sense of place and appreciation of urban density, and transformed perceptions of desirable places to live and work. This study presents a systematic method for evaluating the trade-offs between perceived urban environmental qualities and urban amenities by analysing post-pandemic urban residence preferences. By evaluating neighbourhood Street View Imagery (SVI) and urban amenity data, such as park sizes, the study collects subjective opinions from surveys on two working conditions (work-from-office or from-home). On this basis, several Machine Learning (ML) models were trained to predict the preference scores for both work modes. In light of the complexity of work-from-home preferences, the results demonstrate that the method predicts work-from-office scores with greater precision. In the post-pandemic era, the research aims to shed light on the development of a valuable instrument for driving and evaluating urban design strategies based on the potential self-organisation of work-life patterns and social profiles in designated neighbourhoods.

title	AR + DESIGN: An Experiment in Remote Teaching and Practice using Augmented Reality for Interactive Brick-based Structure Design
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 950-962.
summary	Due to the COVID-19 breakout and its epidemic prevention restrictions, remote communication has become one of the critical solutions that almost every industry is exploring in this post-epidemic era. Likewise, architectural practitioners also look at remote possibilities for current design methods. This paper presents a unique experimental research using augmented reality (AR) immersion technology for interactive brick-based structure design to explore a remote design method overlayed on the spatial context in the architectural draft visualisation and modification stages. It discusses the teaching process and practice outcomes from an online workshop, which is conceptualised to allow participants to learn, master, and apply the proposed remote design method in AR for brick-based structures. For this online workshop, we enrich the current parametric design method to an AR-assisted way for remote possibilities. The employed workflow was driven by an instant connection between 3D modelling software (Rhinoceros 3D), the parametric design plugin (Grasshopper), and the AR immersion plugin (Fologram). This experiment explored and validated the possibility of remote teaching and practice in architectural design education for post-epidemic era requirements.

title	Augmented Robotic Bricklaying

source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 323–332
summary	After experiencing the Covid-19 pandemic, remote communication became one of the key issues in almost every field and discourse. Digital fabrication is no exception, and architects hope to seek a user-friendly way for human-machine interactions. This paper presents experimental research using Augmented Reality (AR) for robotic remote programming. The research tries to develop a unique pipeline and workflow which allows users from different locations to program robots and communicate with machines through AR. A sample workflow has been tested as a series of simple brick assemblies in an online workshop with remote participants. The pipeline allows all users to be able to remotely program and control a robot in AR. For this workshop, we transform the robotic coding method from the traditional computer science way to the plugin-oriented AR visual programming way in Grasshopper. As for the physical outcomes, participants all assembled brick-based structures successfully by programming and operating the robotic arm in AR remotely at the end. Associating the interaction in AR with the robotic arm and programming it with interactive visual input methods will make it easier for architectural practitioners to simulate and control industrial robots for complex structure assembly.

title	HoloBrick: a contextual design and analysis workflow for parametric masonry façade utilizing augmented reality
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 695–704
summary	This paper presents experimental research about developing a contextual design and analysis workflow utilizing augmented reality (AR) technology to enrich the current design process with an immersive experience. The limitation in the current design process is that due to the lack of spatial perception of the architectural draft on-site preview, designers sometimes find it difficult to fully evaluate their design proposals, which often causes unreasonable design outcomes and incomplete related analysis. To respond to the above problems, the HoloBrick research aims to create a unique augmented parametric algorithm for masonry façade designs to develop and validate the proposed contextual AR-assisted design and analysis workflow, which consists of two phases: a) AR contextual design, and b) AR contextual analysis and modification. The research findings highlight the advantages of using AR in the design and analysis process, such as providing immersive preview and interactive input methods, analyzing design outcomes within context, and enhancing draft modifications with better understanding, which are not offered in the current design process.

title	Effects of a Visual Perception-Equipped Fire Evacuee Simulation on the Design Trade-Offs in Students’ Architectural Projects
doi	https://doi.org/10.52842/conf.ecaade.2023.2.259
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 259–268
summary	Architectural education aims to enhance students’ ability to decide on design trade-offs between safety and other building performance factors, but empirical explorations continue to lack valid exploratory methods. To overcome this shortcoming, we investigated the effects of agent-based simulation on students’ design trade-offs between safety and other building performances, such as daylighting and construction costs. To this end, we developed a visual perception-equipped evacuee behavioural model that incorporated responses to building layouts and fire circumstances, including smoke and sprinkler operations. In five building information modelling (BIM)-based empirical design projects, the simulation enabled students’ systematic examination and explicit data-driven trade-offs by providing both quantifiable analytics and representing the responsive behaviours of evacuees under fire circumstances. Compared to norm- and regulation-based extrapolation, the simulation also allowed students to conduct trade-offs easily and decide valid alternatives, with high fulfilment of design intention. We also found that the unexpected behaviours of fire evacuees, such as bottleneck inside smoke and affordance exploration, also influenced students’ trade-offs and decision-making. In this paper, we address the applicability that visual perception-equipped evacuee simulation is a potentially viable method for inclusion in architectural design pedagogy.
