title	Blockchain Grammars for Validating the Design Process
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 406-411
summary	This paper presents and develops the concept of Decentralised Autonomous Organisation (DAO) as a platform for collaboration, via a design scenario in which Blockchain (BC) technology is implemented for validation purposes. The envisioned scenario simulates designers proposing multiple solutions for a given task and adopting shape grammars and environmental analysis and regulations as design drivers. Proposed solutions are uploaded, stored, presented, and evaluated in a DAO in which the decision process gets validated via the reputation of the participants and its governance system. This study lays the foundation and ignites the development of a larger framework in which design collaboration and competition are fostered and results secured, impacting design value and financial transactions.

title	Crop-Centric Agricultural Potential of Urban Surfaces: A Sunlight-Based Computational Approach for Food Security
doi	https://doi.org/10.52842/conf.caadria.2023.2.573
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. 573–582
summary	Urban agricultural systems will be configured over the following years to respond to increasing climate change, urbanisation, and population growth. Controlled environment agriculture (CEA) is an increasing trend since it can be easily integrated into the built environment. However, this food production system requires intensive capital and energy resources, with artificial lighting as the primary contributor to its high operational impacts. New methods and tools for planning and design can provide innovative solutions for shifting urban agriculture toward sustainability. This paper addresses the food security challenge in cities by introducing a sunlight-based computational approach for indicating the agricultural possibilities of three-dimensional urban surfaces according to crop-centric environmental suitability. The procedure aims to improve CEA efficiency through a passive natural lighting optimisation strategy, indicating the sunlight thresholds for various crop species. The methodology interconnects solar radiation values measured through sunlight simulations with crops’ daily light integrals, using Singapore and Chennai (India) as case studies. The results suggest that urban areas with high solar radiation levels possess large degrees of year-round harvesting potential. This methodology can assist designers (architects, urban planners, and engineers) and local governments in strategizing urban agriculture developments and provide decision-making support for crop harvesting initiatives in cities.

title	Quill A Gesture Design Tool for Pen-based User Interfaces
source	U.C. Berkeley
summary	This dissertation describes the motivation, design, and development of a tool for designing gestures for pen-based user interfaces. Pens and other styli have been ubiquitous for recording information for centuries. Recently, pen-based computers have recently become common, especially small devices such as the Palm Pilot. One benefit pens provide in computer interfaces is the ability to draw gestures—marks that invoke commands. Gestures can be intuitive and faster than other methods of invoking commands. However, our research shows that gestures are sometimes misrecognized and hard to remember. We believe these problems are due in part to the difficulty of designing “good” gestures—that is, gestures that are easy to remember and are recognized well—and the lack of tools for helping designers create good gestures. We believe that an improved gesture design tool can help interface designers create good gestures for their applications. Since people confuse similar objects and misremember them, we performed experiments to measure why people perceived gestures as similar. We derived computational metrics for predicting human perception of gesture similarity. Based on the results of our experiments, we developed a gesture design tool, quill. The tool warns designers about gestures that may be hard to remember or recognize, and provides advice about how to improve the gestures. It also provides a convenient way to test recognition of gestures. To evaluate quill, a user study was performed with 10 professional user interface designers and one professional web designer. All designers were able to create gesture sets using quill, but not all designers benefited from quill’s suggestions. More work is needed to make suggestions useful for most designers. The primary contributions of this work are: • Improved understanding of the gesture design process, including the types of problems people encounter when designing gestures. • Computational models for predicting human-perceived gesture similarity. • Confirmation of the importance of good naming for gesture memorability. • An intelligent gesture design tool, quill, which automatically warns designers about potential problems with their gestures and advises them about how to fix these problems. This work also suggests several areas for future work in the areas of gesture design tools and gesture similarity and memorability.

title	Parametric Analysis of Flood Mitigation Policies in Brazilian Climate Action Plans
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. 1229–1240
summary	Climate change has been increasing the vulnerability of cities to extreme weather events, especially those related to environmental dynamics already observed in each area. Considering that South America is one of the subcontinents that suffer the most from flooding, it is important to analyze how its cities have been preparing to face such extreme conditions. This paper aims to investigate the strategies indicated in climate action plans for mitigation and adaptation to flooding through the application of a parametric tool. To achieve this end, the methodology comprises five steps – from data collection to digital simulation. The results attained demonstrate that the strategies indicated in the plans are still very generic and incipient, so that the application of parametric methodologies of analysis and simulation can contribute to the searching for more effective and relevant actions.

title	PARAMETREE: An Algorithmic-Parametric Tool for Evaluating the Contribution of the Trees on Rainwater Management
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1447–1461
summary	This paper explores the application of an algorithmic-parametric tool that uses urban forestry as a design strategy to reduce the occurrence of flooding. The study was carried out following three main stages: (1) a literature review on the capacity of rainwater retention in tree species with dense canopies; (2) the creation of an algorithmic-parametric tool using C# scripting in Grasshopper to calculate the influence of the trees in reducing the runoff coefficient; and (3) a simulation using Rhinoceros and Grasshopper to verify the performance of such tool. The results show a new method of calculation to estimate the runoff formation in urbanized areas as well as it confirms the contribution of the trees in mitigating flooding.

title	Three-dimensional computational structures and the real world
doi	https://doi.org/10.52842/conf.caadria.2011.209
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. 209-218
summary	In this paper, we describe a system of composite images to design virtual three-dimensional structures in an outdoor environment. The system, called AmbiViewer, consists of a modeler for three-dimensional on-site sketching, and overlapping locative technologies to orient virtual objects in a real-space, real-time setting. The system employs both GPS orientation and a visual marker system to provide a realistic and interactive augmented reality interface. While it is still under development, the authors believe it can bridge the gap between sketching on site, and creating virtual models in the office.

title	Consequences for practical aesthetics and for aesthetical theory of the insertion of principles from quantum theory in cellular automata
source	International Conference on Generative Art
summary	A cellular automaton that includes some principles from quantum theory is considered. The automaton generates forms of an aesthetic nature. At every time step, a form grows with a single cell. This cell is selected with a selection probability that is determined by an amplitude. If the algorithm is run with selection of the cell of maximal amplitude at every time step, a type of form results that is called 'platonic'. Such forms typically have higher aesthetic complexity than their non-platonic counterparts. The case of selection probabilities determined by squares of amplitudes has a strong analogy with quantum theory. This analogy is elaborated by consideration of forms that have mutual correlations. These correlations can be of a classical nature, of a quantum mechanical type, or of a type that is termed 'super-correlation'.

title	The art of growth and the solution of cognitive problems
source	International Conference on Generative Art
summary	A cellular method is proposed as an alternative for a connectionist approach. The present method does not use connections between cells, but introduces a field concept instead. If the fields are determined in accordance with the transformations familiar from fractal theory, then the solutions of problems that have some symmetry are forms of remarkable beauty. This way, a link is proposed between generative art and problem solving. It is conjectured that the ‘black box’ nature of connectionist systems can be replaced by an approach in which the solution of a problem coincides with a vivid visualization, also if the problems at hand are of a high-dimensional nature.

summary	This paper will discuss data visualisation in structural engineering for comparing design alternatives. By having the structural information of all different design proposals at hand, the designer is able to make informed design decisions. The authors developed a tool for creating interactive graphs while designing structures in a parametric design environment. In this work a case study of different structural design alternatives of a stadium roof is presented. Based on this design case, some graphs and the new informed design approach will be explained. Also the implementation of the tool within a parametric design environment with its advantages and issues is discussed.

title	Cognitive environments for design: a relational study among traditional and digital media in the conception of the architectural project
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 377-384
summary	This research investigates the cognitive design processes used by architects in conceptualizing design ideas using traditional and digital media. Data were gathered from: an initial design process of two groups of individuals using both design media to complete two videotaped isomorphic tasks; questionnaires; analysis of the retrospective verbal protocols about these tasks. The results indicate that the traditional media still presents advantages against the digital media due to limitations on the state of the art of hardware and software and on the lack of understanding and well handling of the computer by the architects. Some advantages related to the use of traditional media were: it furnishes the architect with more comprehensive perception regarding the relationships between visual, spatial and organizational aspects of the design process, whilst stimulating the production of several alternative solutions, avoiding, therefore, premature crystallizations of design solutions, and a more comprehensive understanding of the design tasks.

title	Multidimensional Analysis of Public Open Spaces - Urban Morphology, Parametric Modelling and Data Mining
doi	https://doi.org/10.52842/conf.ecaade.2015.1.351
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 351-360
summary	Public open spaces (parks, squares and other gathering places) can only be grasped from a simultaneous view of their attributes. In an ongoing Phd research project we propose to overcome the limitations of traditional-descriptive urban morphology methods in dealing with this simultaneity derived from their many shapes, functions, uses and relations within the urban structure. After developing the relations between formal attributes and intangible spatial properties, their identity and proximity may be disclosed by multivariate statistical analysis and data mining techniques. We outline a multidimensional method for the synchronic analysis and classification of the public open spaces departing from a research corpus of 126 Portuguese urban squares, whose analysis is intended to interactively (re)define it. The work done so far is presented, which comprises: (i) firming the concepts, criteria and attributes to extract; (ii) survey on theories, methods and spatial analysis tools and shortcomings identification; (iii) adaptation and/or creation of new methods and tools; (iv) creation of databases from CAD and GIS environments; (v) research on multivariate analysis, data mining and data visualization techniques.

summary	This research introduces Augmented Reality (AR) for manufacturing concrete structures through an open platform for autonomous construction. The study was developed under the following scopes: computational algorithms for bending simulations, materiality tests, system implementation, and a set of Augmented Reality (AR) tools. AR devices offer a technological tool that allows for a self-built environment through holographic guidance, allowing the untrained workforce to participate in the process. This technology can help users select the system to construct through an Open-Source platform, reducing the gap between complex computational geometries and construction processes. The research aims to investigate a building system that could benefit the UN Objectives SDG 10 by increasing the access to technology in undeveloped communities, SDG 11 and SDG 12 by promoting a self-sustainable method of construction based on local resources and material efficiency. In conjunction with the development of the AR Platform and augmented manufacturing, a 1:1 prototype was built in Quito, Ecuador, with the help of seven people with no previous knowledge of digital tools or construction. Presenting a novel, fast, and affordable concrete formwork connected with AR assisted assembly methods that facilitate access to more efficient and advanced building technology.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 43-46
summary	This article reflects on the ethical implications of digital technology (DT) in architectonic design. Such a reflection is based on the definition of complex epistemology and the educational ethical reform (Morin 2000). The article ends with a conceptual proposal of an interactive, multidimensional and collaborative environment of design. The goal is to re-set patterns and strategies of design with DT from plural perspectives and poly-temporal creations, all of it inserted in a complex ethical point of view of a contemporary design. The wanted result is a social 3d network of design that unifies visualization, modeling tools, videoconferencing, chatting, and social-academic network managing.

title	Excavator-mounted ordnance locating system using electromagnetic sensing technology
source	Automation in Construction 7 (4) (1998) pp. 243-258
summary	There are in excess of 20 million acres of bomb and artillery ranges under the control of the Department of Defense (DoD). Each year some 800,000 to 2,000,000 km2 are turned over to civilian (private or commercial) use. Some of this land is contaminated with buried unexploded ordnance (UXO). These UXOs present a safety hazard and raise many environmental concerns. In addition to inaccurate locating, one of the most difficult aspects for the operator of an excavator is the inability to see the target ordnance while it is covered with soil and debris. This paper presents a system which is mounted to the arm of an excavator and is capable of detecting a buried UXO located in the path of an excavator's bucket. Also, the system is able to determine the precise location of the ordnance relative to the excavator's bucket. This information will allow the operator not only to avoid striking the ordnance during the digging operation, but also to expose the object by removing the soil around it. This technology is also capable of locating small UXO which can be buried within the spoil material. This technology has the potential to result in savings of millions of dollars in operating costs and prevent the damage or loss of equipment.

summary	The use of Artificial Neural Networks (ANNs) promises greater efficiency in the assessment of daylight situations than simulations. With the daylight factor under scrutiny and the recent adaptation of climate-based daylight metrics in British and European buildings standards, ANNs provide a possibility for instantaneous feedback on otherwise time-consuming performance metrices. This study demonstrates the application of ANNs as prediction systems in design exploration. A specific focus of the research is the flexibility of ANNs, their reliability and sensitivity to changes.

summary	The design studio 'Flying Bricks' was held during the summer semester 2015. Its main objective was to redesign an existing building with the use of facing bricks algorithmically, utilizing algorithmic thinking and programming as a means for form generation. The purpose of having students express their designs in terms of code was to emphasize problem thinking over solution generation, which has several advantages but also disadvantages which we would like to share in this paper. Furthermore, we would like to show how our implementation process worked, so that others can leverage that for their own algorithmic design courses.

summary	The rezoning process primarily deals with proposed changes on land-use and zoning plans. More and more often, the public is asked for its opinion and feedback. However, there are two main obstacles in today's practice: On the one hand land-use and zoning plans, in general, only define the potential of areas and so do proposed draft plans; they usually say nothing about the implementation of land-use in the built space. On the other hand, the untrained majority can hardly grasp the current form of representation as two dimensional plans with accompanying written information. In order to enable a wider public participation (and understanding), the authors present FLÃ„VIZ, a 3D visualization of potentials on land-use and zoning plans.
