title	Inconsistent Affective Reaction: Sentiment of Perception and Opinion in Urban Environments
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 2, pp. 395–404

summary	The ascension of social media platforms has transformed our understanding of urban environments, giving rise to nuanced variations in sentiment reaction embedded within human perception and opinion, and challenging existing multidimensional sentiment analysis approaches in urban studies. This study presents novel methodologies for identifying and elucidating sentiment inconsistency, constructing a dataset encompassing 140,750 Baidu and Tencent Street view images to measure perceptions, and 984,024 Weibo social media text posts to measure opinions. A reaction index is developed, integrating object detection and natural language processing techniques to classify sentiment in Beijing Second Ring for 2016 and 2022. Classified sentiment reaction is analysed and visualized using regression analysis, image segmentation, and word frequency based on land-use distribution to discern underlying factors. The perception affective reaction trend map reveals a shift toward more evenly distributed positive sentiment, while the opinion affective reaction trend map shows more extreme changes. Our mismatch map indicates significant disparities between the sentiments of human perception and opinion of urban areas over the years. Changes in sentiment reactions have significant relationships with elements such as dense buildings and pedestrian presence. Our inconsistent maps present perception and opinion sentiments before and after the pandemic and offer potential explanations and directions for environmental management, in formulating strategies for urban renewal.

title	Do Visually Perceived Design Qualities Influence Dockless Bikeshare Cycling Routes? A Case Study of Ithaca Using GPS Trajectories
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 2, pp. 99–108
doi	https://doi.org/10.52842/conf.caadria.2024.2.099
summary	Understanding the influences of the built environment (BE) characteristics on the dockless bike-sharing system (DBS) is crucial for supporting and developing sustainable transportation mode. Previous studies on DBS cycling have primarily investigated the effects of macro-level BE characteristics (e.g., land use) or limited street features (e.g., greenery), overlooking that of perceived street design qualities such as enclosure. To better understand whether and how street-level environment characteristics, especially perceived street design qualities, influence DBS cycling routes, we calculate cycling volume based on GPS trajectories in Ithaca, a small town in New York State, and then quantify visual features and perceived design qualities using street view imagery (SVI) and computer vision (CV). Our analysis, employing linear regression and spatial regression models while controlling macro-environmental attributes as covariates, reveal the significant association between perceived design qualities and DBS cycling trip volume, confirming the significance of considering design qualities in DBS cycling studies. Geographically Weighted Regression (GWR) model explains the spatially heterogeneous effects of street-level attributes, offering practical suggestions for informing spatially varying policies and interventions for creating a cycling-friendly environment.

doi	https://doi.org/10.52842/conf.caadria.2021.1.573
summary	This research presents a novel method of robotic fabrication for customizable fiber-reinforced polymer (FRP) tubular formworks, which also function as reinforcements for large-scale structural components. This process is achieved by the spatial weaving of FRP fabric driven by a robotic arm, and calibrated with the fast-cure resin which is applied on the fabric and cures during the weaving process so the fabricated structure is self-supporting and the structure is formed in an additive manner. With this method, structural members with changing sections can be customized and fabricated rapidly with off-the-shelf materials, following a system of structural reinforcement that has been widely adopted in the construction industry and promotes new applications of construction robotics.

title	Teaching Digital Design Exploration: Form Follows
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 685-702
summary	This paper presents some challenges of teaching computational geometry to architectural students, and proposes a multi-level pedagogical scheme introducing associative geometry and parametric modeling/design into architectural design education. It reports on two pedagogical experiences: one held in the context of a spatial geometry course in the first year of education; and another one, in a digital design studio with third-year architectural students. More specifically, it discusses the impact on design exploration of a library of interactive referents models introduced into the architectural studio. Situated in the 'performance' paradigm of digital design methods, they allow for design object explorations based on modification of architecturally meaningful features (structural, environmental, functional, etc.). The form of a design object can thus 'follow' function, structure, or even sustainability. The digital methods and the design knowledge transferred by the interactive models, together with their visual nature, are found to amplify the processes of 'seeing-as' and the 'reflective conversation with the situation' considered essential for creative design.

title	A Tool for Conceptual Design Evaluation Based on Compliance with Site-Development Briefs and Related Planning Regulations
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.c6i
summary	The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.

title	Efficient Computer-User Interface in Electronic Mail Systems
source	Department of Computer Science, April, 1981. ii, 24 p. includes bibliography
summary	This research explores the question of improving user- computer interface. The approach is one of observing and codifying various parameters that influence the efficiency of interface in the context of electronic mail tasks. In the paper the authors observe 'expert' and 'regular' users of a mail system and analyze the sources of efficiency. It is clear that experts use a different, more specialized, set of commands in performing standard mail tasks. While experts perform these tasks with fewer errors and more 'completely,' it is not clear that they achieve this any faster than regular users. Recommendations for design are made

title	Linking Land Use Modelling and 3D Visualisation - A mission impossible?
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 85-101
summary	Additional to the traditional land use maps 3D visualisation could provide valuable information for applications in the field of spatial planning, related to ecological and agricultural policy issues. Maps of future land use do not always reveal the appearance of the physical environment (the perceived landscape) as a result of land use changes. This means that 3D visualisations might shed light on other aspects of changed land use, such as expected differences in height or densities of new volume objects, or the compatibility of these changes with particular characteristics of the landscape or urban built environment. The Land Use Scanner model was applied for the Netherlands Environmental Assessment Agency's 'Sustainability Outlook' to explore land use changes, followed by GIS analyses to asses both the development of nature areas and the degree of urbanisation within protected national landscapes. Since it was felt that 3D visualisation could complement the resulting land use maps, the land use model output was coupled to 3D visualisation software in two different ways: 1) through Studio Max software in combination with iconic representation of the concerned land use types and 2) through 3D components of GIS software. However, the use of these techniques on a national scale level for the generation of semi-realistic 3D animations raised a number of conceptual and technical problems. These could be partly ascribed to the particular format and of the Land Use Scanner output. This paper discusses the methods and techniques which have been used to couple the output of the land use model to 3D software, the results of both approaches, and possible solutions for these problems.

title	Agent-agent interaction as a component of agent-environment interaction in the modelling and analysis of pedestrian visual behaviour
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 555-564
doi	https://doi.org/10.52842/conf.caadria.2011.555
summary	This multidisciplinary project involves concepts from architectural design, statistical learning, machine vision, and human ecology. The focus is on analysing how pedestrians’ dynamic behaviour in space is influenced by the environmental design of different architectural scenarios. This paper presents a multi-agent pedestrian simulation and analysis system that supports agent-to-agent interactions, different spatial desires, and interpersonal distance. The system simulates and analyses pedestrian spatial behaviour with combined focus on movement trajectories, walking speed, and the visual gaze vector. The analysis component relies on learning a statistical model characterising normal/abnormal behaviour, based on sample observations of regular pedestrian movements without/with the impacts of significant visual attractions in the environment. Using the example of Wheeler Place in Newcastle (Australia) our pilot experiments demonstrate how pedestrian behaviour characteristics can depend on selected features in the visual environment. The presented system will allow architects and urban designers to obtain better assessment of planned urban spaces and streetscape characteristics and their impacts on pedestrian behaviour.

title	Computer aided environmental simulation and evaluation
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	In this study, the perceptions of on a computer screen displayed street photographs, were compared with the experiences of their real-life counterparts. Using a semantic descriptive method, SMB, experimental subjects assessed eight urban environments, presented both in field and on computer screen. Assessments were made in different light and seasonal conditions. It was shown that the perception of street pictures, presented on computer screen, did correspond well with the experience of the outdoor originals in most of the used semantic descriptive dimensions. Discrepancies between the two presentations were generally small and comparable with the minor perceptual differences between the various light conditions. Deviations could also be ascribed to certain non-perceptual factors, like the subjects' backgrounds or the environments' cognitive peculiarities. The findings indicated also possible improvement of the computer presentation technique by widening the pictures' informational content.

title	Computer-aided design systems for the 21st century: some design guidelines
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper proposes nine design principles for a new generation of computer-aided design (CAD) systems that actively support the decision making and problem solving activities of environmental design. Foremost among these are: a meaningful internal object-based representation of the artifact being designed within its environmental context; a collaborative problem solving paradigm in which the human designer and the computer form a complementary partnership; and, the notion of decision-support tools rather than predefined solutions. Two prototype computer-aided design systems implemented by the CAD Research Center that embody most of these concepts are described. ICADS (Intelligent Computer-Aided Design System) incorporates multiple expert agents in domains such as natural and artificial lighting, noise control, structural system selection, climatic determinants, and energy conservation. Given a particular building design context, the agents in ICADS draw upon their own expertise and several knowledgebases as they monitor the actions of the human designer and collaborate opportunistically. KOALA (Knowledge-Based Object-Agent Collaboration) builds on the multi-agent concepts embodied in ICADS by the addition of two kinds of agents. Mentor agents represent the interests of selected objects within the ontology of the design environment. In the implemented KOALA system building spaces are represented by agents capable of collaborating with each other, with domain agents for the provision of expert services, and with the human designer. Facilitator agents listen in on the communications among mentor agents to detect conflicts and moderate arguments. While both of these prototype systems are limited in scope by focussing on the earliest design stages and restricted in their understanding of the inherent complexity of a design state, they nevertheless promise a paradigm shift in computer-aided design.

title	Architectural Forms by Abstracting Nature
source	International Conference on Generative Art
summary	The structures in nature are great lessons for human study. Having been in development for several billion years, only the most successful structural forms have survived. The resourcefulness of material use, the underlying structural systems and the profound capacity to respond to a variety of climatic and environmental forces make natural form tremendous exemplars to human architectures. The wholeness of natural form indicates that the form and forces are always in some sense of equilibrium. In most of natural forms, the quality of equilibrium may be difficult to recognize. However, seashells are one of the natural forms whose functions are simple enough to be approximated by a simple mathematical relationship. The focus of this study was to understand the seashell form as applicable to human architectures. Digital methods are the language to analyze, create, and simulate seashell forms, as well as, suggest a variety of possible architectural forms.

title	The Body in the Mind: The Bodily Basis of Meaning, Imagination, and Reason
source	University of Chicago Press, Chicago, Illinois
summary	This is the first work which systematically put together a sensible story about the intermodal structures (image schemata) linking high-level cognition, like langauge, with the body-rich information of perceptual processing. Johnson's image schemata was the first proposal for this project which was both neurally plausible, given the organization of the cortex into topology preserving maps (contradicting Fodor and Pylshyn's mistaken view), and supported by the evidence from development, in language and conceptual structure. This book spawned debates on schematization in fields ranging from developmental psychology, cognitive psychology, linguistics, philosophy, neurocomputational modeling, and neuroscience. When the st century cognitive neuroscience writes its chapter on the way semantic processing works at a neural level, it will need to refute those 20th century philosophers of language who thought that language was primarily referential, truth-conditional, and operated on symbols formed independently of bodily perception. This book will be the touchstone for that project.
