title A Computational Method for Tracking the Hygroscopic Motion of Wood to develop Adaptive Architectural Skins
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 253-262
summary Low-cost programmable materials such as wood have been utilized to replace mechanical actuators of adaptive architectural skins. Although research investigated ways to understand the hygroscopic response of wood to variations in humidity levels, there are still no clear methods developed to track and analyze such response. This paper introduces a computational method to analyze, track and store the hygroscopic response of wood through image analysis and continuous tracking of angular measurements in relation to time. This is done through a computational closed loop that links the smart material interface (SMI) representing hygroscopic response with a digital and tangible interface comprising a Flex sensor, Arduino kit, and FireFly plugin. Results show no significant difference between the proposed sensing mechanism and conventional image analysis tracking systems. Using the described method, acquiring real-time data can be utilized to develop learning mechanisms and predict the controlled motion of programmable material for adaptive architectural skins.

title Re-flex: Responsive Flexible Mold for Computer Aided Intuitive Design and Materialization
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 1, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 717-726
summary The paper presents an ongoing research about the design and a possible use of a responsive flexible mold. The mold is developed by integrating its precedents with automation and Human-Computer Interaction (HCI). The objective of the design is to provide an immersive design tool which has direct link to fabrication. It allows intuitive interaction to its user in order to help with the design and production of complex forms by supporting the designer's implicit skills with computer. The paper presents the design by illustrating the use of the hardware such as the actuators, the sensor and the projector; and by defining the workflow within the software. The paper concludes with the description of a possible use case in which the system is used to design and materialize an object in different scales.

title The flexibility of logic programming : Parametrically regenerating the Sagrada Família
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. 29-38
summary Flexibility is a major attribute of parametric modelling, however designers find it hard to maintain flexibility throughout their projects. One cause may be the programming paradigm of the parametric model. Currently this is dataflow programming, which makes it easy to create and flex parameters, but difficult to modify relationships. This paper investigates the implications of changing the programming paradigm in a parametric model to logic programming. A qualitative account is given of using dataflow programming and logic programming to generate a portion of the Sagrada Família church. It finds logic programming adept at translating explicit models into parametric models, but lacking continuous flexibility. This research demonstrates there are different types of flexibility within the model and architects can privilege certain flexibility types by selecting the programming paradigm of the model.

title SMAAD Surface: A tangible interface for smart material aided architectural design
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. 355-364
summary In this paper, we present Smart Material Aided Architectural Design (SMAAD), the design technique to realize intuitive shape modelling with synchronizing a tangible user interface (TUI) and a 3D CAD system. To realize SMAAD, we first implemented SMAAD Surface, the TUI that imitates the free-form surface. The TUI is a fabric device, in which flex sensors and actuators (shape memory alloys) are embedded. As a designer changes the textile shape using his/her hands, its surface data will be sent to the CAD system through the sensor and a free-form surface can be created in the PC. The operation in the opposite direction is also possible, in which the CAD surface data is sent to the fabric device to dynamically change its shape. SMAAD releases architectural designers from complex GUI operations and visual programming and enables digital model creation through natural manual operations for physical models.

title Modelling Behaviour of Configurable VR Applications
source International Journal of Architectural Computing vol. 7 - no. 1, 77-103
summary Creation of complex behaviour-rich and meaningful content is one of the main difficulties that currently limit wide use of virtual reality technologies in everyday applications. To enable widespread use of VR applications new methods of content creation must be developed. In this paper, we propose a novel approach to designing behaviour-rich virtual reality applications, called Flex-VR. The approach enables building configurable VR applications, in which content can be easily created and modified by domain experts or even common users without knowledge about VR design and computer programming. The VR content is configured from reusable programmable content elements, called VR-Beans. Appearance and behaviour of the VR-Beans are controlled by scripts programmed in a novel high-level language, called VR-BML (Behaviour Modelling Language). The language enables specification of generic behaviours of objects that can be dynamically composed into virtual scenes. The paper introduces the Flex-VR component and content models, describes the VR-BML language and provides an example of a Flex-VR application in the cultural heritage domain.

title Morphologic Multi Criteria Decision support forconceptual Integral Design of Flex(ible En)ergyInfrastructures
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary To ensure a good information exchange between different disciplines during the conceptual phase of design a functional design process structuring technique can be used; Integral Design. The design phases and abstraction levels form the dimensions of Integral Design method/contents matrix. Integral Design method is developed based on the combination of a prescriptive approach, Methodical Design, and a descriptive approach, Reflective practice. This design methodology uses morphology to provide an overview of the consider functions/aspects and their solution alternatives. This morphological approach is combined with the Kesselring method a visualization technique, where the different design variants can be compared with each other. It forms an excellent method for Multi Criteria Decision Making in the conceptual phase of design. This paper investigates the application of Integral Design and Multi Criteria Decision Making for design of Flex(ible En)ergy infrastructure for the built environment.
