title	Assessing Spatial Accessibility to Public Facilities for Vulnerable People towards 15-Minute City in Hong Kong
doi	https://doi.org/10.52842/conf.caadria.2023.1.535
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. 535–544
summary	Due to the COVID-19 pandemic, people started to rely more on their communities and attach great importance to the accessibility of public facilities at a hyperlocal level. The 15-Minute City concept, first put forth by Carlos Moreno in 2016, gradually gained popularity worldwide during the age of pandemics. This human-centric concept aims to build complete neighbourhoods that meet the daily needs of residents within 15 minutes by using non-motorized transport. However, few studies focus on vulnerable groups such as children and the elderly for the assessment of 15-Minute City. Therefore, this paper provides an assessment framework for spatial accessibility to public facilities for vulnerable people from the perspective of 15-Minute City. It is measured in three aspects: spatial distribution characteristics, service population ratio and number of facilities through the comparison between Sham Shui Po and Tin Shui Wai in Hong Kong. The result shows that the accessibility to public facilities needed in daily life for children in Sham Shui Po and Tin Shui Wai is relatively reasonable, while the accessibility for the elderly needs to be improved. The research can provide references for evaluating and optimizing spatial planning to promote health and well-being in Hong Kong and other cities.

title	Extrusion-to-Masoning: Robotic 3D Concrete Printing of Concrete Shells As Building Floor System
doi	https://doi.org/10.52842/conf.caadria.2023.2.139
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. 139–148
summary	Efficient floor systems can reduce the carbon footprint of building industry by reducing material, thereby responding to the UN Sustainable Development Goals (SDGs). Tile vault, a kind of masonry shell structure in history, can provide inspiration for extrusion-based 3D concrete printing. In this research, an “Extrusion-to-Masoning” perspective is proposed to evaluate, analysis, and simulate 3DCP. The variable-width filaments of 3DCP can be interpreted as variable-width bricks. The staggering pattern between different layers is studied. Three concrete shells with different layer-staggering patterns are printed and quantitative structural testing experiments are carried out. Then a totally printed floor slab prototype is designed and fabricated at the basis of one of the shells.

summary	In recent years, additive manufacturing (AM) and 3D concrete printing technologies have been increasingly used in the field of construction engineering. Several 3D concrete printing bridges were built with post-tensioning technology. However, the current post-tensioned 3D concrete printing projects are mostly in a single direction of force. There are fewer cases of concrete printing funicular spatial structures, and most funicular spatial structures are currently manufactured by casting-in-place in formwork. This paper presents a case of manufacturing spatial 3D concrete printed structure using post-tensioned technology with multiple force direction. The design of the non-parallel printing path, the joints between single units, and the post-tensioned steel cable system in the design and research process are discussed. A funicular spatial structure is built, and a method of manufacturing 3DCP funicular spatial structure is proposed.

title	The Computer Media Method of Analysis of Architecture Works
doi	https://doi.org/10.52842/conf.caadria.1999.097
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 97-103
summary	The analysis of architecture works is through the design of architecture. It is closely related to the review of architecture and also is the most important method to research into and study architecture. But it hasnÌt been paid enough attention, because of the limitations of the traditional methods. Now with the development of the computer media technology and its wide use, there appears a new methodÛthe computer media analysis method, which has many advantages that the traditional methods havenÌt. In this paper, we discuss the frame, the process and the feature of the new method. And through the analysis of examples we explore the working of this method under the current condition. We hope through the research and the study of this new method, the analysis of architecture works can be used consciously by students, educators, and practitioners to think deeply about, research into, study architecture, and at the same time to creating better designs.

title	Robotic Equilibrium: Scaffold Free Arch Assemblies
doi	https://doi.org/10.52842/conf.acadia.2018.342
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 342-349
summary	Compression only arch structures are structurally highly efficient in force equilibrium. However, the material efficiency is offset by the traditional use of scaffolds to position materials and counter the out of equilibrium forces during assembly. We introduce a method of sequentially assembling compression only structures without a scaffold by robotically maintaining the compression equilibrium in every step. A two-arm collaborative robotic setup was used to maintain force equilibrium throughout arch assembly with the arms taking turns first hot wire cutting and placing blocks and providing a temporary scaffold to support the arch end point. To test the approach, a single catenary arch was generated using form-finding techniques and sequentially built from foam blocks. Moving forward we show the relationship between the joint valence (largest number of joined branches) of a multi-branched structure and the minimum number of robotic arms required for assembly using our initial technique. With only two robotic arms available, the technique was further developed to reduce the required number of arms per arch branch from two to one by attaching caterpillar tracks at the block supporting end effector. This allows a human to load the next block and the arm to move forward along the arch while maintaining equilibrium. Results show that robotic equilibrium scaffold free arch assembly is possible and can reduce scaffold waste and maintain the material efficiency of compression only structures. Future work will explore further applications of assistive robotics in construction replacing static construction aids with dynamic sensory feedback of equilibrium forces.

summary	The urgency for an inclusive architectural design process in conceptualizing the built environment stems from the need to establish effective communication between under- represented groups and design professionals. However, various challenges hinder the development of an inclusive design process that accommodates diverse stakeholders. Individual designers or selective design teams are frequently limited by their own visions, causing them to potentially overlook alternative solutions. Moreover, stakeholders who lack professional training might struggle to articulate their expectations. The emergence of generative AI (artificial intelligence) technologies has significantly reduced the tech- nical barriers in design, and has empowered non-professionals to vividly express their ideas regarding forms and spaces. This has presented a valuable opportunity to better understand the perspectives of underrepresented groups through visual representations. Therefore, this research aims to explore the impact of image generation on the democ- ratization of the design process. Using chair design as a testing ground, we propose an evolutionary computing framework that simulates interactions among designers and participants empowered by emerging AI technologies. To investigate the potential impact of image generation, we have implemented a multiplayer design game to allow computing agents to compete in exploring 3D chair forms. Through this approach, we aim to gain insights into how image generation influences design decisions, whether it generates more diversified solutions, and what values could be introduced into the built environment.

summary	Responsive environment uses human computer interface (HCI) to improve how human experience their surrounding. Many research aimed at different kind of interactive environment modules with new digital tectonics or computation components. However, those new environments are sometimes could be manipulated by components which are less use-friendly and complex than traditional counterparts. In this paper, we implemented a real responsive interface – the Spark wall system, which use 160 actuator modules as our responsive feedback interface and depth camera as sensing input. We built up multi-modal interface for different operating purposes allowing user control responsive environment with their human behavior. User could change their body posture to change the pattern of the wall and moreover define touch-input area on any surface. For the user’s perspective, a responsive environment should be simply and understandable control. A responsive artifact should also be able to dynamically correspond to different methods of operation according to the user's intentions.

summary	This paper proposes a physical toolkit and a flexible software framework to simplify the design and exploration of interactive systems for multiple users, devices, and applications in a smart environment. The toolkit, called Elastic-Room, was designed as an infrastructure for interaction design, in which each device is a component that works collaboratively in the smart environment. The supporting software framework includes a dynamically reconfigurable intermediary which simplify the mapping of each device and also use simple protocol to broadcast information to each device. Finally, we demonstrate the Elastic-Room architecture by providing some implemented examples, which are organized in a prototype space of ubiquitous computing full of interactive components.

title	Improvement of the horizontal directional drilling method by using an autonomous land vehicle with a radio direction finding system
source	Automation in Construction 11 (1) (2002) pp. 75-88
summary	This article discusses the improvement in the horizontal directional drilling method (HDD) by using an autonomous land vehicle (ALV) with a radio directional finding (RDF) system. The ALV with an RDF system carrying a receiver can locate a moving or static underground drill head and track it. Not limited to a pre-determined track or path, the ALV system utilizes its on board RDF system instantaneously to seek and to track a moving or static drill head. Compared to conventional systems, the system reduces the number of operators, minimizes labor costs, prevents accidents, and enhances the degree of automation.The design of the RDF system and how to locate a target are considered in this article. To overcome the difficulty in obtaining the precise dynamic model of the ALV with the RDF system, a "fuzzy logic controller" is designed to control such a system and make the system capable of tracking a target. Experimental results verify that such an RDF ALV system can track a moving or static target.

title	A smart bracelet: An alternative interfaces between performer and audience
doi	https://doi.org/10.52842/conf.caadria.2016.311
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 311-319
summary	Performing arts has been one of the main recreational activ- ities in people’s life. However, most performing arts, performers usu- ally used one direction to express performing contents to the audienc- es. It means there is no real-time communication channel between the performers and audience in most performance. Hence the challenge of this research is how to provide a better relationship between the per- formers and audience without disturbing the show? This research we implemented a bio-sensor embedded smart bracelet which is able to transmit the feelings from user’s to stage by monitoring biological signal (ex: Galvanic skin response) immediately. When most audienc- es have the same physiological reaction to a certain level, the stage scene would be changed the colour and pattern to let performers know how the audiences’ feeling now. Performers would enhance self- confidence and then incorporate the audiences’ feedback to create their future performance. By applying this interactive interface to per- forming arts, we explored a new vision of performance that can not only enhance the diversity of performance but also provide a comfort- able communication channel between performers and audiences, and improve the confidence of the performers.

title	Computer Aided Dimensional Control in Building Construction
source	Eindhoven University of Technology
summary	Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

title	3D Space Resilience Analysis of Commercial Complex - Beijing APM as an Example
doi	https://doi.org/10.52842/conf.caadria.2021.2.457

summary	Commercial complexes have played an increasingly important role in contemporary cities. Due to the occurrence of crowded people or equipment overhauls, some paths in a commercial complex may become impassable, which can be seen as disruptions to its spatial system. This paper provides a practical method to quantify the spatial resilience of a commercial complex taking Beijing APM as an example. This study can be divided into the following three steps. First, transforming the realistic spatial path system to a directed network model. Second, using topological, metric, and angular distance as edge weight to calculate the centrality and present its distribution. Third, using two disruption processes, randomized and attractor-guided strategy, evaluates the spatial networks resilience. There are three conclusions from this study. The first one is the process of disruption is non-linear, and there is a phase transition process when it reaches the critical threshold. The second one is the most efficient disruption method is the topological BC attractor-guided strategy. The last one is the resilience of a commercial complex, whose 3D spatial networks resilience is lower than the 2D spatial networks resilience by comparison with Duan and Lus (2013) study.

title	The Cognition of Residential Convenience Areas Based on Street View Image's Entropy and Complexity - Beijing as an example
doi	https://doi.org/10.52842/conf.ecaade.2021.1.545
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 545-554
summary	This paper quantifies the convenience of living in Beijing by calculating street view image's two inherent properties, entropy and complexity. The image's entropy H can measure the degree of disorder in its pixel arrangement, and the complexity C can measure the "structure" of its pixel arrangement. The study methodology can be divided into four steps as follows. (1) 20,194 Baidu Street View (BSV) images of random geographic coordinates within the study area are crawled as the dataset. (2) Calculate the entropy and complexity of each image separately and plot the entropy-complexity plane. (3) Clustering of data points on the entropy-complexity plane using the K-means algorithm. (4) Analysis of the geographical distribution of the different cluster's data points. The following two conclusions can be drawn from this research. Firstly, low entropy and high complexity street view images can characterize built-up urban areas where the sky occupies a large area, and its buildings are usually more uniform. Conversely, high-entropy and low-complexity images can characterize areas with the more complex built-up environment. Secondly, street view images representing high residential convenience areas in Beijing are characterized by high entropy and low complexity.

summary	Building Information Modelling (BIM) has been widely accepted as an integration tool that enables modelling of form, function, and behaviour of building systems and components. Using BIM, building design can be approached in a more logical way by integrating spatial, structural and mechanical systems as well as cost and energy performance in the early design stage. In this paper, we develop a design framework using BIM in varied design processes, including architectural programming, conceptual design, parametric design, digital fabrication, and interaction design. We conducted an experiment to reform design studios using BIM throughout the design process. A classroom of the future called iSTUDIO is constructed by applying BIM, parametric design, interactive technology, and digital fabrication.

title	A Comparative Investigation into a Process-Based Approach to Lighting Studies Using Physical and Computer Generated Models in Design Studio
doi	https://doi.org/10.52842/conf.caadria.2000.107
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 107-121
summary	This pilot research attempts to investigate differences in process between lighting study using physical model and computational simulation. A Physical modelling team, a computational modelling team, and a monitoring and tracking team were formed to process and monitor the research by a defined workflow of the design process. Using a time schedule technique, the procedures of each of the two methods were tracked. The research reveals that the research team favoured physical modelling for its ease of use and computational simulation for its flexibly. And that the users of physical models were more aware of the need for technical knowledge whilst the users of simulation software are more contended with the virtual results without evaluating them critically. In addition, the experiment also shows that the feedback mechanism of the physical modelling process is instant, continues and intuitive, whereas that of the computational process is discrete. Preliminary results not only confirm the long established view that the computational process lacks the tactile quality required for architectural understanding; worst still, it gives inexperienced users an illusion of knowledge and claims of understanding. Due to limitations of time, the research captures only the feasibility stage of the design process, further works involving a more comprehensive design program should be conducted.

title	A Framework for Predicting the Visual and Non-Visual Effects of Daylighting Based on Multi-Objective Optimization Tool

summary	Many studies have shown that the non-visual effects of daylighting have a positive effect on human physiological health. However, due to non-visual effects are different from visual effects in spectral distribution, influencing factors and evaluation standards, the existing lighting simulation software cannot satisfy both visual and non-visual evaluation simultaneously. Based on a review of the latest non-visual studies, the research team developed a climate-based simulation framework devised to investigate both the visual and non-visual effects of daylighting in buildings simultaneously by using multi-objective optimization tool. The simulation framework integrates four functional modules, including boundary conditions input, simulation of visual and non-visual effects, multi-objective optimization calculation, and result output and analysis. A total of 12 computing components are written through Ghpython for data processing and visual expression. The applicability of the simulation framework is demonstrated using a real standardized classroom in Nanjing, P.R. China. The simulation framework generated three optimal daylight design schemes, which significantly improved indoor visual and non-visual effects of daylight. The results suggest that the framework can be used to assess the performance of various daylighting design strategies which simultaneously consider visual and non-visual effects.

summary	Virtual reality is widely used to present architectural design space. It has also provided a solution that general public without architectural design background can easier understand complex space which has not been constructed yet. However, how much information could general public understand, while browsing design space presented by virtual reality? In this study, we have compared the experimental results from one with architectural design background and the other without architectural design background in different space factors such as form, scale, organization, circulation of space. Finally, we conclude some preliminary phenomena from the data. The phenomena could be the guidelines to the design of spatial navigation in the system of virtual reality. Keywords. Architectural

summary	In the current era, the utilization of 3D positioning maps for Augmented Reality (AR) registration is becoming increasingly prevalent, particularly in indoor guidance. This research endeavors to investigate issues related to the construction of 3D positioning maps and their application in navigation by developing an AR-guided app for a historical and cultural park. The study reveals that the use of 3D positioning maps enables the precise and stable presentation of virtual information within specific physical spaces. A majority of participants reported a positive AR navigation experience using this app. However, challenges arise when applying 3D positioning maps in outdoor settings, where factors such as tree shadows and the lack of distinctive patterns on asphalt roads can impact positioning quality. Ideally, environments with distinctive patterns are better suited for presenting AR content through 3D positioning maps. The findings of this research serve as valuable insights for future developments in map-based AR navigation systems.

summary	Computer media develop progressively day by day. In the process of designing architecture, the employment of digital model seems to become more significant while the traditional physical model have still been used. However, the physical model had some unique characteristics which digital one has not. And those characteristics were what we intended to discover and put into the digital modeling environment developed by us.
