title	Sight Depth Illusion with Perforated Plane - Evaluate in Mixed Reality with Head Mounted Display
doi	https://doi.org/10.52842/conf.caadria.2018.1.411
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 1, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 411-420
summary	This paper examines the existence of a visual illusion with depth of sight involving a perforated panel layered above another plane, evaluates the illusion's properties with virtual projection on a see-through, head-mounted display, and illustrates the relation between the veridical and perceived distances through a mathematical expression. The result would be indicative to egocentric spatial analysis research, and reveal potentials as a reference point for a new architectural design tool.

title	A Survey of 3D Interaction Techniques
source	Computer Graphics Forum, 165
summary	Recent gains in the performance of 3D graphics hardware and rendering systems have not been matched by a corresponding improvement in our knowledge of how to interact with the virtual environments we create; therefore there is a need to examine these further if we are to improve the overall quality of our interactive 3D systems. This paper examines some of the interaction techniques which have been developed for object manipulation, navigation and application control in 3D virtual environments. The use of both mouse-based techniques and 3D input devices is considered, along with the role of feedback and some aspects of tools and widgets.

title	Development of interior finishing unit assembly system with robot: WASCOR IV research project report
source	Automation in Construction 5 (1) (1996) pp. 31-38
summary	The WASCOR (WASeda Construction Robot) research project was organized in 1982 by Waseda University, Tokyo, Japan, aiming at automatizing building construction with a robot. This project is collaborated by nine general contractors and a construction machinery manufacturer. The WASCOR research project has been divided into four phases with the development of the study and called WASCOR I, II, III, and IV respectively. WASCOR I, II, and III finished during the time from 1982 to 1992 in a row with having 3-4 years for each phase, and WASCOR IV has been continued since 1993. WASCOR IV has been working on a automatized building interior finishing system. This system consists of following three parts. (1) Development of building system and construction method for automated interior finishing system. (2) Design of hardware system applied to automated interior finishing system. (3) Design of information management system in automated construction. As the research project has been developing, this paper describes the interim report of (1) Development of building system and construction method for automated interior finishing system, and (2) Design of hardware system applied to automated interior finishing system.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	This paper reports on the findings of an empirical investigation into the use of the computer as the only design media in solving a design problem. Several 1st and 2nd year students took part in a two week experiment on the use of a CAD programme, AutoCAD 13 and AEC 5.0, to design a studio for a graphic designer. Prior to the experiment an extensive literature search was carried out to explore the relationship between the design process, visual thinking, conventional sketching (interactive imagery) and Computer Aided Design. Out of this search a number of design variables were identified, developed and then tested through a series of observations and interviews with the students while they were engaged in the design of the Graphic Designer’s Studio. Questionnaires were also administered to students to explore their views on issues including, using CAD instead of conventional tools, design areas where CAD is most effective, and how CAD can improve design skills.

title	A fuzzy logic approach to the selection of cranes
source	Automation in Construction 8 (5) (1999) pp. 597-608
summary	This paper presents a fuzzy logic approach to select the best crane type in a construction project from the main crane types, namely, mobile, tower and derrick cranes. Each factor of the project is classified as being dynamic or static according to whether the factor does or does not depend on the particular project. Linguistic information about the suitability of each crane type with respect to each factor of the project is translated into either fuzzy sets (for static factors) or fuzzy if–then rules (for dynamic factors). The fuzzy rules are then aggregated into a fuzzy relation between the space of factor property and the space of crane efficiency. In a particular project the experts describe the property as well as the relative importance of each factor. The rules are then fired using the max–min extension principle, and the resulting efficiencies are aggregated with their importance weights. The process identifies the best crane as the one with the highest expected overall efficiency.

title	An inquiry into computers in design: attitude before-attitudes after
source	Design Studies, 22(3), pp. 255-281
summary	This paper reports on the findings of an empirical investigation into the use of the computer as the only design medium. A group of students took part in an experiment to design a studio for a graphic designer on the computer. Student attitudes towards the design process were assessed at two conditions: before using the computer and after using the computer. Prior to the experiment a literature search was carried out to explore some widely researched design issues such as sketching, design creativity, and computer-aided design. Consequently a number of design variables were identified, developed and then empirically tested. Data collection methods included questionnaires and observations. Statistical analysis of the responses confirms that using the computer has produced a statistically significant difference in attitudes to the design process variables.

title	A Computer-based Approach for Teaching Daylighting at the Early Design Stage
doi	https://doi.org/10.52842/conf.ecaade.1996.181
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 181-190
summary	This paper has reviewed the literature on the teaching of daylight systems design in architectural education, and found that traditionally such teaching has evolved around the prediction of the Daylight Factor (DF%), i.e. illuminance, via two methods one studio-based and another laboratory based. The former relies on graphical and/or mathematical techniques, e.g. the BRE Protractors, the BRE Tables, Waldram Diagrams, the Pepper-pot diagrams and the BRE formula. The latter tests scale models of buildings under artificial sky conditions (CIE sky). The paper lists the advantages and disadvantages of both methods in terms of compatibility with the design process, time required, accuracy, energy-consumption facts, and visual information. This paper outlines a proposal for an alternative method for teaching daylight and artificial lighting design for both architectural students and practitioners. It is based on photorealistic images as well as numbers, and employs the Lumen Micro 6.0 programme. This software package is a complete indoor lighting design and analysis programme which generates perspective renderings and animated walk-throughs of the space lighted naturally and artificially. The paper also presents the findings of an empirical case study to validate Lumen Micro 6.0 by comparing simulated output with field monitoring of horizontal and vertical illuminance and luminance inside the highly acclaimed GSA building in Glasgow. The monitoring station was masterminded by the author and uses the Megatron lighting sensors, Luscar dataloggers and the Easylog analysis software. In addition photographs of a selected design studio inside the GSA building were contrasted with computer generated perspective images of the same space.

title	Can IT bridge the Gulf between Science and Architecture?
doi	https://doi.org/10.52842/conf.ecaade.1998.078
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 78-86
summary	The integration of technology into design work has always been seen as one of the serious problems in design education. In architecture the weak integration between architectural science, a subject based on objective knowledge, and artistic design which is based on tacit knowledge and creativity is a problem that has been debated to great length, and an issue of great importance to both academics and professionals. This paper raises the question: can a proper use of IT, both as a design tool and/or as a performance analysis tool, foster better integration and strengthen design quality? This paper investigates the relationship between Science, Design and Computer Aided Design. It aims to both highlight the problems facing the integration between architectural science and design, and describe a framework within which they can be analysed. The paper critically examines the following: a) The perceived gulf between science and design b) The parallels between hypothesis in design and hypothesis in science c) The basis of architectural design: intuition or research? d) Architectural Science and Computer Aided Design (CAD) and the role they can play into bringing about a marriage between science and design.The paper concludes by developing a conceptual framework that can be used as a vehicle to build a CAD system for use during the design process.

title	Creativity of ‘Process’ and ‘Product’: The Impact of Tools?
doi	https://doi.org/10.52842/conf.ecaade.2015.1.169
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. 169-178
summary	This paper examines the relationship between creativity domains and computing tools. It reports on the findings of a design computing experiment with 2 groups of subjects while they were engaged with a problem solving design task using two types of CAD tools, non-parametric and parametric-algorithmic. The paper aims to address two questions. Does a more creative process by implication 'correlate' with and yield a more creative product? And does the 'type' of CAD tool deployed by the user impact on the creativity of their product? The findings revealed that creativity of the process correlated significantly with each measure of 'product' creativity, namely: novelty, technical goodness and aesthetic appeal. Factor loading on components confirmed two constructs, one for product creativity and another for process. Additionally a difference in CAD tools produced no statistical 'variance' in creativity of 'product' or process. A regression equation to predict product ratings from creativity process ratings is also presented.

title	Parametric Tools and Creativity in Architectural Practice
doi	https://doi.org/10.52842/conf.caadria.2015.613
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 613-622
summary	This paper empirically tested the relationship between creativity and computing tools in two different architectural practice settings: one that extensively uses parametric tools for design and fabrication and another that predominantly uses conventional CAD tools in design. The paper surveyed 14 parametric practices and 17 non parametric practices from the UK. The results were statistically analysed using IBM_SPSS (Statistical Package for Social Sciences). The analysis of variance between the 2 groups revealed significant differences on the four domains of creativity. Statistical variance between the two groups on originality was big. Also the length of time subjects used parametric tools correlated significantly with three measures of creativity (fluency, variety and elaboration). Cluster analysis on design cognition of the two groups showed significant pattern differences on how each group structures the design process.

summary	This paper tracked the progress of 24 students who were ‘intensive’ users of CAD and 26 ‘occasional’ CAD users over a 3 year period. At the end of each year, student attitudes toward creativity dimensions were monitored, using questionnaires and semi-structured interviews. The collected data was analyzed with the Statistical Package for Social Sciences (SPSS). The statistical tests displayed a signifi cant difference between both groups in terms of ideation fl uency and ideation fl exibility (P<0.05). Within the intensive CAD group the tests also yielded signifi cant differences between years (P<0.05). Ideation fl uency correlated positively with years of study and was infl uenced by CAD and design maturity both as a ‘main effect’ and as an ‘interaction’. The cognitive preference for complexity as a design trait in the intensive group also correlated with the increased complexity of the digital tools used; preference for low complexity correlated with the use of direct CAD tools whereas higher levels of complexity correlated with the deployment of parametric and generative tools.

title	Tools as Design Instruments: Computers and Cognition?
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. 1-12.
summary	This inquiry researches the impact of digital tools on the design process and empirically tests the association between computer aided design tools and each of cognition and creativity in architectural practice. The paper analyses the ‘design-tool’ relationship and reviews research in the field of computers as an instrument for creativity, examines their deductions and conducts a case study. Statistical analysis of the case study suggests that three measures of creativity correlated significantly with the length of time a subject spends using the computer in design: rho=0.487, P<0.05 for elaboration of design ideas; rho=0.605, P<0.05, for volume of ideas; rho=0.687, P<0.05, for ideation variety. Also, the length of designer-computer interaction seems to scaffold various forms of design reasoning and help cognition: rho=0.591, P<0.05. The study found little evidence to support the notion that computers prevent other forms of knowing.

title	Digital Processes in Architectural Design:A Case Study of Computers and Creativity
source	International Journal of Architectural Computing vol. 4 - no. 2, 95-120
summary	This paper describes the results of a statistical-experimental investigation into the relationship between three variables: design cognition, the computer as a problem solving medium and 'creativity'. The hypothesis put forward suggests a directional link between the use of 'CAAD as a cognitive design medium' and 'levels' of creativity in the design process. The hypothesis was tested statistically using first year architecture students as research design subjects. In order to place the research within a context, develop a thesis and identify 'operational' measures for variables, a literature search with special emphasis on 'creativity' was conducted. The statistical findings did confirm that levels of architectural 'creativity' in the design process and in the final product were somehow affected by the use of CAAD. Ideation fluency and originality, as 'creativity' indicators, correlated positively with CAAD as a cognitive medium with coefficients 3 0.5. The statistics from subjects- group design- revealed that computers' power of visualisation, slicing and Boolean operations has helped spatial ability and could eventually help novice designers to venture and create complex objects more than they would normally do with conventional media.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 374-379
summary	This paper presents an experimental approach that examines human response to three virtual representations (sketchy line, non-photorealistic and near-photorealistic) of three similar architectural schemes (in terms of concept, context and scale) within a non-immersive large-screen projected virtual environment. Participant response is recorded utilising the factors of detail, spatial understanding, character and presence. By comparing data it should be possible to draw conclusions about aspects particular to non-immersive Virtual Reality (VR) activity as a means of architectural representation.

title	Enabling Optimisation-based Exploration for Building Massing Design - A Coding-free Evolutionary Building Massing Design Toolkit in Rhino-Grasshopper
doi	https://doi.org/10.52842/conf.caadria.2020.1.255
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 255-264
summary	This paper presents an evolutionary design toolkit for performance-based building massing design optimisation. The toolkit is aimed to assist architects in exploring a wide range of building massing design alternatives guided by various performance objectives, thereby encouraging architects to incorporate evolutionary design optimisation for enriching design ideation at the outset of the design process. The toolkit is implemented in the Rhino-Grasshopper environment and includes components of a diversity-guided evolutionary algorithm and two pre-defined parametric models capable of generating a wide range of massing designs. The evolutionary algorithm can yield diverse design variants from the optimisation process and present more informative results with higher design differentiation. The pre-defined parametric models require minimal customisation from the architects. By using the toolkit, architects can readily explore high-performing building design with performance-based design optimisation with ease, and the coding-free optimisation workflow also streamlines the design process.

title	Digital Fabrication for Retroreflective Ceiling Treatment - Reducing Speech Distraction in an Open Work Environment
doi	https://doi.org/10.52842/conf.caadria.2018.1.317
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 1, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 317-325
summary	This paper presents a case study for the production of retroreflective ceiling treatment in an open work environment. In this setting with multiple talkers, speech distraction can be a significant cause of dissatisfaction and loss of productivity. Ceiling treatment in open plan work environments can provide an important way of ameliorating distraction from unattended speech, and rather than absorbing the sound at the ceiling, this paper examines the possibility of reflecting sound back to the source. Computational design and digital fabrication are integrated in this research for a site-specific deployment of the ceiling treatment and physical testing of prototypes in an acoustics laboratory. The contemporary possibilities that open up with new technologies to understand and resurrect faceted geometries and potentially vary historical precedents via new manufacturing techniques are demonstrated in these novel acoustic reflective ceilings that reflect sound back to their original source.

summary	This paper examines faceted tessellations in an acoustic vault ceiling typology for the enhancement of human speech comfort in multi-listener environments. Geometric modelling explores simulated results for various tessellation arrangements within the overall segmentation of a global ceiling geometry. Where pattern-based design for acoustic surfaces often overlooks the optimisation of vault typologies, the tests demonstrated in this research seek a trade-off between acoustic properties and faceted detailing. This involves the performance-based design of micro joint topologies and ruled-surface geometries, and a macro-analysis of the vaulted surface for acoustic studies embedded into this workflow, using Pachyderm software.

summary	Standard evolutionary algorithms have limited use in practical architectural design tasks. This may be due to the poor search efficiency and the lack of diversity of the result. In order to overcome these weaknesses, this paper proposes a hybrid evolutionary algorithm combining an island model approach (parallel distributed technique) and a steady-state replacement strategy for maintaining a rich design diversity of the result while speeding up the search process. Through a demonstration, it is shown that the hybrid algorithm can effectively improve both design diversity and search efficiency.

summary	This paper contributes to a new way of bringing the human physically into the in-situ environment and utilizing mapping methods of the actual sonic experience, which current acoustic studies and other environmental studies are lacking in their reliance on graphical representations. An entire era has been dominated by a visual communication of the sonic environment, yet sonic studies are not primarily dependant on visual experience. The paper reviews the possibilities of current methods of representation of the sonic experience. Representation, being crucial in the layperson’s perceptive awareness of key features of the environment can benefit from increased levels of listening methods. This includes mapping the qualities of information that reveal the environment.
