summary	John Portman's work attracts much interest, although little scholarship exists that directly engages his contribution in formal composition. Most of the discussion of Portman's architecture tends to focus on his commercial work and hotels, although a key to understanding his work is found in his personal domestic projects where he has had the freedom to explore his architectural ideas. This study focuses on his first residence, Entelechy I, to begin outlining his design principles formally. The ambition is to open up the whole question of his architectural contribution in the United States and at large.

summary	The prevalent mode of shape grammar output is a two-dimensional drawing grammar. For architectural applications, these two- dimensional shape rules can hold a variety of interpretations in three-dimensional space. This work translates an existing grammar from a manual two-dimensional drawing grammar to an automated three-dimensional building grammar to explore the challenges and opportunities that this translation suggests in the larger context of shape computation. The case study considered here is a grammar interpreting John Portman’s architectural language as defined by the house Portman identifies as emblematic of his design principles, his 1964 personal residence Entelechy I.

title	Ceramic Perspiration: Multi-Scalar Development of Ceramic Material
doi	https://doi.org/10.52842/conf.acadia.2012.097
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 97-108
summary	Ceramic building material is a useful passive modulator of the environment. The subject area is based on traditional cultural and material knowledge of clay properties: from amphora to rammed earth building; and ranges to present uses: from desiccants and space shuttle tile patterns to bio-ceramics. The primary consideration is to control material density and porosity in a tile component, in response to specific environmental conditions. This depends on a number of key physical principles: the ability of the material to absorb thermal energy, the ability to absorb and then ‘wick’ moisture within the pore structure, and the decrement factor or ‘time lag’ of the effect. The interplay between these properties point to the importance of directionality in the porous microstructure, at the boundary layer. Material characteristics have been investigated in the laboratory at a micron scale and in the ceramics workshop at full scale, with some interplay between the two. Recent work done on monitoring has led to the development of software tools that allow feedback (approaching real time)- a visual representation of the dynamic thermal and hygrometric properties involved.

title	G Pen: An Intelligent Designer’s Playmate
doi	https://doi.org/10.52842/conf.acadia.2003.403
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 403-409
summary	In the field of design the pen-based system is a newly developed computer interface that provides the designer with the convenience of a pen in freehand sketches. But these pen-based systems only focus on an interface familiar to the designers and the application of the hardware and software that go with it, treating the pen only as a mouse-like input device. As pen and pad are devices for the pen-based system, the hope is that they can be endowed with more intelligent characteristics to let them interact with designer’s gestures and become a creative source for the designers, while simultaneously preventing the design fixation encountered by designers during design process. This research utilizes the unintentional hand gestures made by designers, such as the designer’s grip of the pen or movement involved in playing with the pen, putting it down, knocking it, twisting it or shaking it, during the thinking process or when running into a design fixation. From the interaction between the pen and the pad, certain actions may be generated to stimulate the designer’s thinking process. This research uses a neural network as the main learning mechanism for the eventual development of a prototype of a pen-based drawing system that provides timely visual stimulation: a G Pen system.

title	Is a pen-based system just another pen or more than a pen?
doi	https://doi.org/10.52842/conf.ecaade.2003.615
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 615-622
summary	Freehand sketch is the most critical stage in the design process. The importance of the freehand sketch is in its ability to freely represent various projections of ambiguous drawing using a convenience tool, pen-and-paper. Recently, pen-based system which developed attempted to use pen as an input device, allowing sketches to be freely drawn on computers. However, as far as the various drawing projections, such as diagram, symbol, plan, elevation, section, perspective, etc., how are they interrelated to a designer’s cognitive behavior? Different media have different abilities to represent projections. What’s the difference of design cognitive behavior between conventional pen-and paper and pen-based system in view of both using a pen as a design medium? This research proceeds a think-aloud protocol analysis to present an analysis and discussion. Research results show that there is a relationship of gradual embodiment, mutually complementary, going from a whole to being dissected into sections between the different projections. Moreover, pen-based system is more than a pen, it allows designer to inspect a 3-D view during the sketching stage. This gives the designer more opportunities during the sketching stage to conduct the design thinking process based on the ambiguous 2-D projections and the more concrete 3-D images, as well as more opportunities for visual feedback

title	An Insight into the Freedom of Using a Pen: Pen-based System and Pen-and-paper
doi	https://doi.org/10.52842/conf.acadia.2003.385
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 385-393
summary	In earlier researches on freehand sketching, the cognitive behavior of designers was studied. In recent years, some researchers began to look into this area from the design media aspect. The pen-based system, developed by Gross, Landay and other researchers, used the pen as an input device, allowing sketches to be freely drawn in a computer environment. The importance of the freehand sketch lies in its ability to freely represent various drawing projections using ambiguous sketches. However, as for the various drawing projections, such as diagrams, symbols, plans, elevations, sections, perspectives, etc., how are they interrelated to a designer’s thinking process and the cognitive behavior? Different media have different abilities to represent different projections. Would they affect the designer’s design thinking as well? Targeting different media, i.e., conventional freehand sketches vs. the computer pen-based system, this research uses case studies and think-aloud protocol analysis to present an analysis and discussion. Research results show that there is a relationship of gradual embodiment that is mutually complementary, going from a whole perspective to being the dissected into sections between the different projections. In addition, these projections restrict the designer’s various design thinking processes, while the use of different media may somewhat change the actual design thinking of the designer

title	Presence Stickers: A Seamlessly Integrated Smart Living System at a Solitary Elderly Home
doi	https://doi.org/10.52842/conf.caadria.2022.1.445

summary	This research develops Presence Stickers, the capacitive sensing module that can be easily affixed to the existing space element surfaces (such as a wall, door, stairs), and daily objects or home furniture (such as a chair, cabinet, table, sofa, etc.). These 30*30 cm Presence Stickers can actively sense people‚s physical behaviors and body movements in spaces. From the preliminary analysis of observing the 80-year-old elderly subject‚s daily activities, the movement trajectory of the ‚Move-Stop‚ pattern is found. There will be a Touch (T) and Touchless (TL) relationship between the body and the space elements or objects. Furthermore, the touchless, or non-contact, intimate relationship can also be divided into two types: 1. The body that ‚Passes by‚ (P) the spatial elements or objects, and 2. The body that ‚Stays‚ (S) in front of the object and performs activities. These three types of the intimate relationship between bodies and objects, i.e., T, TL-P, and TL-S, were used as the main sensing conditions to develop the Presence Stickers sensor module. We affixed 8 Presence Stickers on 9 objects in six spaces and finally, the life pattern can be analyzed and the sensors provide the customized intelligent application function for the elderly.

title	A Software Environment for Designing Through Robotic Fabrication – Developing a Graphical Programming Toolkit for the Digital Design and Scaled Robotic Fabrication of High Rises
doi	https://doi.org/10.52842/conf.caadria.2013.045
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 45-54
summary	The term “robot” was born from a play written almost a century ago. Today robotic fabrication has become an emerging topic in architectural research. As architects work with these technologies, they are challenged with writing a different kind of play: here robots are the actors and the physical materialization of a design is their performance. However current Computer Aided Design (CAD) packages do not provide native robot programming functionalities which architects require to plan and orchestrate these fabrication process. To address this limitation, a Python library for robot programming is written. It is referenced by a toolkit of custom components developed to extend a graphical programming environment commonly used for architectural design. The empirical development of these software tools takes place in the context of a design studio investigating the subject of the high rise. The tools are tested in a workflow that involves the digital design and scaled robotic fabrication of high-rise housing. This paper discusses the considerations underlying the toolkit’s design, the outcomes of its use in the studio, and its impact on the creative design process.

summary	Existing buildings are often lacking BIM models. This paper proposes a method to semi-automate the generation of BIM models from 2D CAD drawings. The method has two parts: the first part, 2D CAD drawing preparation, involves cleaning the drawings to obtain simplified 2D input geometry and the second, 3D BIM model generation, involves generating and extracting parameters to generate 3D BIM components. This research focuses on the semi-automation of the second part. The the model is generated storey by storey, with each building element type being processed. A demonstration was carried out for a case-study building. The main modelling strategies used by the method are described and key challenges are discussed.

title	Shape Exploration in Design: Formalising and Supporting a Transformational Process
source	International Journal of Architectural Computing vol. 6 - no. 4, 415-433
summary	The process of sketching can support the sort of transformational thinking that is seen as essential for the interpretation and reinterpretation of ideas in innovative design. Such transformational thinking, however, is not yet well supported by computer-aided design systems. In this paper, outcomes of experimental investigations into the mechanics of sketching are described, in particular those employed by practicing architects and industrial designers as they responded to a series of conceptual design tasks. Analyses of the experimental data suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules. A set of shape rules, formalising the reinterpretation and transformations of shapes, e.g. through deformation or restructuring, is presented. These rules are suggestive of the manipulations that need to be afforded in computational tools intended to support designers in design exploration. Accordingly, the results of the experimental investigations informed the development of a prototype shape synthesis system, and a discussion is presented in which the future requirements of such systems are explored.

summary	Hospitalization is, for the patient, a neuropsychophysiological stressor, thus pertinent theories point to architectural stimuli as a tool for the homeostasis restoration and consequent well-being. Furthermore, they compile advantages to the patients’ treatment and highlight, mainly, the natural environments benefits, which is elucidated by the Biophilia theory. Through literature review and analysis of applied research in national and international hospitals, extracted from indexing databases of scientific production in the 2000-2020 timeframe, it was found that these areas [a] promote stimuli that enhance emotions and positive feelings; [b] act to restore stress and anxiety; [c] reduce pain, analgesic intake and length of stay; and [d] increase patient satisfaction. By sharing the results of this research, the objective is, in addition to stimulating future research on the organism behavior in the environments, to indicate perspectives for hospital ambiences.

summary	In order to design an ephemeral pavilion located at the Serpentine Gallery (England), an experimental design approach was developed in this paper by using biomimicry strategies associated with parametric modeling. Exploring the solution-based methodology, the analysis of the sartorius muscle anatomic features such as rotation, flexion and long shape allowed inspiring the proposal of a Sartorius Pavilion which is the object of study. The experiment was implemented throughout a parametric visual script tool resulting in a model capable of rapidly and intuitively simulating shape variations, basic structural and material attributes by modifying a set of previously defined parameters.
