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	Real - time Minor Deformations that Result from Collisions Using Bump and Normal Mapping
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 240-243
summary	This paper presents a method for simulating minor deformations that result from collisions on objects’ surfaces. The method alters only bump maps and leaves mesh geometry unchanged; it is suited to real - time applications where the primary concern is computational efficiency. The paper provides a representative model for deformable objects. Texture mapping and computer graphics techniques based on lighting are referenced as well. Finally, results are provided, along with the most noteworthy findings obtained with the use of this method.

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	Buoyant Memory - Neuroscience for a Virtual Architecture
doi	https://doi.org/10.52842/conf.ecaade.2015.1.055
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. 55-60
summary	Gravity prescribes a very specific maxim for the built environment represented by the horizontal layer cake we are all so familiar with. This is contrasted by designs such as the International Space Station where no floor is present and every surface provides some function whether storage, data display and instrumentation or biological support infrastructure. Because of the homogeneity of approach to each surface an astronaut requires literal markers to orient oneself within the vessel. Very seldom within the natural, earth-bound environment does one find oneself in a situation where “up” is a questionable vector. What happens when architecture is translated to the virtual. What is the role of the architect or of his or her architecture in a virtual universe. Would a virtual architecture itself not become a social engine, its social context being that of online gaming, crowdfunding and social media? This engine's main role being the creation of architecturally inspiring gathering spaces for learning, playing and community building.

summary	Computer assistants to building process management are not able nowadays to efficiently work out the problems generated by the increased complexity of designing. Actual difficulties depend, on one hand, on the fact D.B.M.S. that have been developed on other environments than CAAD, and on the other hand, on the fact that architectural design process is scarcely formalized. At the Department of T.E.C.A., at the University of Rome, a PhD research program is aimed to overcome difficulties, working out techniques of information management based on Knowledge Engineering and particularly on Knowledge Base Management Systems and Expert Database Systems. At present a prototype system is being developed, that can manage existing technical information, connected with buiIding process.

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	Structural Performance Modelling in Architectural Design Education
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In architectural education the process of design has evolved with the development of CAD technology. In many design schools throughout the world, the computer has extended its role beyond that of a drafting machine to become a tool for performance modeling. Applications currently used by students test lighting, thermal conditions, and structural validity, to name a few. However the goals in education are not identical to those in practice, and digital modeling can support learning in many ways that are not particularly useful or appropriate in professional practice. In the design of structures there are three fundamental levels of understanding: behavior, form, and performance. Each has its place in design education and uses digital modeling in different forms. This paper describes various pedagogical models that incorporate computer aided drawing and performance modeling in the teaching of structures. Examples of student exercises and projects are discussed.

summary	Collaborative work in architecture is commonly concentrated on the design process. Design teams and their members are working together on multiple virtual model from different, mostly remote locations. Internet- based collaboration software offers a project management platform for comprehensive networking. Complex projects can bebetter coordinated and documented,and executed even faster. So in the building process at least two different kinds of collaboration can be noticed, collaboration in the design process where the architects are maintaining their modeling informations, and the construction process where the data is maintained be external software companies. Here another model is suggested. Hosting project data in their own building and so maintaining the physical representations of all project informations is the only way retaining control.

summary	The inevitable and obvious distinction between virtual and real worlds is a result of an assumption, that objects in computation are either digital or not. With new concepts like Mixed- or Augmented-Realities this simple standardized differentiation has become questionable. The infl iction of real objects upon virtual models can not be ignored.

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.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 495-499
summary	This project describes a way to combine real-world images with graphical representations of three-dimensional objects.In architecture the combination of physical and virtual spaces is a traditional approach to propose the design of a building. Presenting a virtual design as it appears in relity requires either an unsatisfying level of abstraction while being on-site, as with sketches, or the performing of several ardous tasks. While in this case the quality is appropiate, it is now unlikely to get immediate results.Combining an interactive modeler as the primary designing instrument with a augmented reality system as mixture of cameras, GPS-devices and fiduciary features the system can demonstrate how augmentation as tool in architecture might work.

summary	Mobile devices like cell phones, handhelds, and other gadgets are useful tools in organizing and communicating. This is going to change. Recent developments in hardware have proven that such small devices are much more capable and have reached the levels of common laptops as of five years ago. With more computational power, more memory, and new methods of interaction such as touch screens, or accelerometers, mobile devices can be used in the design process.However, the assumption that they can, or will, substitute desktop computers might be misleading. By no means will mobile devices substitute them directly. Instead, thinking of them as innovative tools that provide new approaches in the design process can establish new methods and, consequently, might circumvent the overall need of desktop computers at all.

summary	Smart architecture has become a widespread term. In general it relates to computational components in buildings interacting with either the environment or the inhabitants. The term ’smart’ itself leads to irritations, because objects can neither be smart by itself nor can a somehow applied smartness make a whole building smart. The presentation of some projects created by means of the Makers’ culture shows an alternate pass to handle computational and interactive elements in buildings as part of the concept of empathic architecture.
