summary	Computer Aided Architectural Design (CAAD) decisions and judgments have been at the heart of architectural design practice. Despite the increasing popularity of computer aided design applications, measuring the decision making of designers empirically remains elusive. Past research claiming usefulness of the CAD has relied largely on anecdotal or case studies that are vulnerable to bias. The study reviews results of prior investigations. The relatively few laboratory experiments report hardly any empirical results regarding the measurement of CAD decision making. The study provides an overview of the literature of existing measurement methods that have been used in psychology and neuroscience to assess individual variations in design making, and highlight these different measurement methods’ strengths and weaknesses. We conclude with a comparative evaluation of the different measures and provide suggestions regarding their constructive use in building realistic theories of designer’s decision making measurement.

title	Feature of Users’ Eye Movements during a Distributed and Synchronised VR Meeting using Cloud Computing

summary	Owing to cloud computing Virtual Reality (cloud-VR), a note PC or tablet with no need for a high spec GPU can be used for sharing a 3D virtual space in a synchronous distributed type design meeting. This research investigates the users’ eye movements and optimization of the GUI of cloud-VR during a distributed and synchronized VR meeting. Firstly, a townscape design support system based on cloud-VR was constructed. Then, a 30-minute experiment was executed with eight subjects who wore an eye-tracking system. In conclusion, it was effective to use the eye-tracking system because meeting participants could discuss while confirming each other’s eye direction in an actual distributed and synchronized VR meeting. In scenes where a reviewer listened to a presenter’s explanation, the tendency to look at VR contents other than operation commands was observed. On the other hand, the tendency to look at operation commands about viewpoints, such as “walk-through” and “jump” to an important viewpoint location, was observed in scenes about which a reviewer argued with a presenter.

title	Computing Level of Privacy in a Virtual Environment
source	International Journal of Architectural Computing vol. 11 - no. 1, 65-86
summary	This paper presents a computational model designed to analyze architectural space and to a develop privacy level using two methods: visual distance method and viewing angle method as those are primary cognitive mechanism to experience architectural space.We suggest that the result will offer possibilities for quantitative design analysis of privacy that influenced by architectural elements.The proposed method consists of two stages: determination of subdivided enclosed spaces and measuring privacy level on each subdivided enclosed space. Previous models showed that spatial quality is related to the visual distance to the architectural elements. In addition to distance variables, our model includes viewing angle variables to determine area and the direction angle from any observation point to the architectural elements on the boundary of an interior space.The case study evaluation is able to rank the quality of design of interior spaces with respect to their privacy level.

title	Understanding Cognitive Activities in Parametric Design
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 38-49.
summary	Parametric design offers a new paradigm in the field of ComputerAided Design; a paradigm focused on the potential for producing design variations. However, despite this potential, the cognitive activities associated with parametric design are not well understood. The authors of this paper present a formal method for capturing cognitive activities via protocol analysis. To support the interpretation of this method, this paper evaluates creativity implicit in design products by way of a consensual assessment technique. The findings identify two cognitive activities (‘making generation’ and ‘changing existing parameters’) as potential critical to divergent thinking and the restructuring of design components. These activities facilitate the generative aspects of parametric design. The paper concludes with a discussion of three cognitive levels (physical, perceptual and conceptual) that support an understanding of cognitive activities in parametric design.

summary	In this paper we examine the strategies used in 3D modeling for their efficiency. Our study explores the underlying cognitive process that drives design thinking as well the choice of strategies for using specific features in a given CAD software. We take a cognitive task analysis approach to examine our question. Of a total sample of 19 participants, the strategies of the fastest and slowest users are compared to identify areas of improvement for software development as well as user training.

title	Material Cognition: Designer’s Perception of Material in a Creative Design Process
source	SIGraDi 2013 [Proceedings of the 17th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Chile - Valparaíso 20 - 22 November 2013, pp. 23 - 26
summary	The new trends in digital design and fabrication attempt to utilize material information as a generative factor in the design and form exploration processes. An investigation on the designers’ cognitive processes in perceiving materiality in an integrated design process could potentially impact these integrated digital endeavors. As a result, this research explores the role of materiality as an external representation based on two main concepts in cognitive science, situated and distributed cognition.

title	Impact of Using Rule Algorithms on Designers’ Behavior in a Parametric Design Environment: Preliminary Result from a Pilot Study
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 13-22.
summary	This paper presents preliminary results from a pilot protocol study of the cognitive behavior differences of designers in a parametric design environment and a traditional geometry modeling environment. The aim is to explore the impact of the rule algorithm feature in parametric design by comparing designers’ behavior in these two design environments. Three architects participated in the experiment in which each of them was required to complete two design sessions, one in each environment. The protocols are coded using the function-behavior-structure (FBS) coding scheme. Preliminary results show that the overall behavior is not significantly affected by the environment; however, there are significant differences at different design stages in the two design environments.

title	Comparing designers' behavior in responding to unexpected discoveries in parametric design environments and geometry modeling environments
source	International Journal of Architectural Computing vol. 11 - no. 4, 393-414
summary	This paper presents a protocol study which compares designers' behaviors when unexpected discoveries appear in a parametric design environment (PDE) and a traditional geometry modeling environment (GME). From the view of design situatedness, designers tend to adapt and respond to the design situation as it continuously changes during the design process. The hypothesis is that when unexpected discoveries appear, these changing design situations can significantly affect designers' cognitive activities. In this study, we are interested in exploring designers' behaviors in responding to these unexpected discoveries in PDEs, and further, to compare those behaviors in GMEs. An experiment was conducted in which five designers completed two similar design tasks respectively in a PDE and a GME. Applying the research method of protocol analysis, designers' behaviors in response to unexpected discoveries in these two design environments are compared and discussed.

title	Reconfiguring Architectural Space using Generative Design and Digital Fabrication: A Project Based Course
source	SIGraDi 2013 [Proceedings of the 17th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Chile - Valparaíso 20 - 22 November 2013, pp. 391 - 395
summary	This paper discusses a course that addresses the integration between generative design and digital fabrication in the context of reconfiguring architectural space. The objective of the course, offered for 3rd year architecture students at the Department of Architecture, Ain Shams University, Egypt, was to design and fabricate interior design elements to be installed within the department lobby. Students worked in digital and physical environments to develop 8 group projects that featured concepts of shape grammars, L-systems, fractals and cellular automata. The potential of the realized projects is discussed in terms of 3D development of systems, contextual generative design, and pedagogical objectives.

title	The Return of Nature as an Operative Model: Decoding of Material Properties as Generative Inputs to the Form-Making Process
source	International Journal of Architectural Computing vol. 11 - no. 2, 267-284
summary	The abandonment of nature as an architectural model and the redefinition of the relationship between form and material were two of the main consequences of industrialization for modern architecture. While nature was replaced by the machine as a model for architecture, industrial production suppressed the craftsman's knowledge of the material and the associated techniques once essential to the form-making process. Thus, the replacement of nature as a model implied that principles once related to natural processes started to be seen as industrial values, i.e., the economy of means stopped being recognized as a quality related to natural form-making processes and became a demand of industrial production. Nowadays, material properties and nature are being reintroduced into architecture with the help of digital technologies; that is, the return of nature though computation. As a result, nature has become an operational model as opposed to the visual or iconic one it used to be; its inner qualities and processes are being decoded in order to inform the form-making process and foster innovative digital ornamentation.

summary	In order to achieve interactive architecture it is necessary to consider more than the technological components of sensors, controllers, and actuators. The interaction can be focused to different interaction activities: instructing, conversing, manipulating, and exploring (we propose to call this the interaction view). Additionally, the purpose of the building may range from performing, sustaining, servicing, symbolising, to entertaining (we propose to call this the world view). Combined, the interaction view and world view establish 20 different attitudes, which are flavours of behaviour for the interactive building. Through attitudes interaction profiles can be established and criteria derived for the design of interactive buildings.

summary	This paper sets out to document the procedural design and implementation of “Siphonophore” a multisensory digital ecology, mimicking colonial-ordered behaviour systems. The exploration of the notion of “self” in a complex system of highly integrated individuals with reference to the emergence of behaviours from the human-machine-context interaction, is engaged by this open system’s hierarchical articulation of electronics, Arduino boards, sensors and programming routines. User interaction and recorded statistics from the system’s core algorithm are assessed, in relation to the capacity of this prototype to provide an alternative methodology of describing collective intelligence, while presenting a non-standard perspective of body-space interaction and design as entertaining art. The overall impact is discussed in relation to the examined observations, towards a potential advancement to a system of superior contextual understanding.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

title	Frameworks for Computational Design of Textile Micro-Architectures and Material Behavior in Forming Complex Force-Active Structures
doi	https://doi.org/10.52842/conf.acadia.2013.281
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 281-292
summary	Material behavior can be defined as the confluence of associative rules, contextual pressures and constraints of materialization. In more general terms, it can be parameterized as topologies, forces and materiality. Forming behavior means resolving the intricate matrix of deterministic and indeterministic factors that comprise and interrelate each subset of these material- nherent conditions. This requires a concise design framework which accumulates the confluent behavior through successive and cyclical exchange of multiple design modes, rather than through a single design environment or set of prescribed procedures. This paper unfolds a sequencing of individual methods as part of a larger design framework, described through the development of a series of complex hybrid- structure material morphologies. The “hybrid” nature reflects the integration of multiple force-active structural concepts within a single continuous material system, devising both self-organized yet highly articulated spatial conditions. This leads primarily to the development of what is termed a “textile hybrid” system: an equilibrium state of tensile surfaces and bending-active meshes. The research described in this paper looks to expose the structure of the textile as an indeterministic design parameter, where its architecture can be manipulated as means for exploring and differentiating behavior. This is done through experimentation with weft-knitting technologies, in which the variability of individual knit logics is instrumentalized for simultaneously articulating and structuring form. Such relationships are shown through an installation constructed at the ggggallery in Copenhagen, Denmark.

summary	Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.

summary	This research explains the development process of a design tool that can construct complex surface geometries using only two-dimensional plan drawings. The intention behind this tool is to address certain complex behavior of surface geometries such as hydrological characteristics. This paper briefly explains the historic and mathematic description of surface data structures, according to Cayley, Maxwell and Morse. This is followed by a brief introduction of the surface network/critical graph extraction technique in GIS. Additionally, the algorithm of contour extraction from asimple critical graph to reconstruct a surface is explained. In the final section the lessons learnedfrom the previous sections are used to develop algorithms for a tool which uses only plan drawings to construct complex surfaces. Three algorithms are explained in the final section among which the third one is considered to be the most complete and promising approach. Therefore,some design examples are presented to show the flexibility of the tool. At the end, this paper provides suggestions and discussions to reflect further ideas in order to improve the tool in future.
