title A context immersion of mixed reality at a new stage
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. 199-208
summary This paper presents a novel approach to the potential of mixed reality embodied in smart phones and ubiquitous environments. We analyzed the related works to the concept of context and mobile computing and then investigated into leading companies by interviewing senior manages of the mixed reality (MR) projects in Korea. As a result, the concept of context immersion is proposed for describing the various context relationships among the real locations, objects and persons. By considering the MR environments as a converged world, this paper characterizes the context immersion as the combination of the time & location-based, object-based and user-based contexts. Through the context immersion, users can be connected to the real life, not limited to the imagery world, thus experiencing strong immersion in the MR environments. At the end, we present the development direction for the future with a focus on the MR contents rather than the technical aspects.

title Rethinking and Designing the Key Behaviours of Architectural Responsiveness in the Digital Age
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. 359-368
summary In the late 1960s the architect Nicholas Negroponte introduced that the physical environment could exhibit reflexive and simulated behaviours, an idea that has since been widely explored. Despite of this wider interest, there is not, however, a systematic approach to understanding architectural responsiveness in the digital age. This paper aims to provide a formal way to facilitate designing smart and interactive artificiality in the built environment. This paper presents a conceptual framework, through exploratory studies on recent architecture, highlighting four key behaviours: (1) tangible interaction, (2) embodied response, (3) ambient simulation, and (4) mixed reality. In addition, two essential enablers, collectiveness and immersion, are proposed to enhance these key behaviours. This framework can be used as a tool to systematically identify and characterise the responsiveness of "responsive architecture". The creative mixtures of the key behaviours will contribute to the development of unique responsive environments.

title Investigating Visibility Properties in the Design of Aged-Care Facilities
source P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 365-374
summary This paper uses a Space Syntax approach - a computational and mathematical method using graph-based measurements - to undertake a comparative assessment of the visibility properties of three architectural plans with unusual spatial requirements. Specifically, the method is used to compare the spatio-visual properties of an idealised plan for a residential aged-care facility with the actual plans used for two facilities. The purpose of this analysis is to begin to examine the ways in which syntactical values and isovist properties can be used to capture spatial and social characteristics of plans designed for the physical and cognitive needs of an ageing populace. The application of this approach seeks to support a better understanding of the relationship between spaces and their social properties in the design of aged-care facilities.

title Multi-Cultural Design Communication
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. 531-540
summary The paper examines a method combining cognitive and linguistic approaches to investigate design protocols. The method is applied in a pilot study to compare Australian and Swedish language protocols recorded in an experiment using a parametric design environment. The results demonstrate that the coding schemes can formally capture both cognitive and linguistic characteristics of the design process. This multi-focused approach directly contributes to a better understanding of the relationship between design and language.

title Exploring Design Strategy in Parametric Design to Support Creativity
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. 489-498
summary This paper deals with the generative and evolutionary aspects of parametric design. We aim to provide a better understanding of individual design strategies to support creativity in parametric design via protocol analysis. An in-depth analysis conceptualises subjects’ creative strategies into two models: problem-driven strategy and solution-driven strategy. The solution-driven strategy progress design in the solution space resulted in the highest value in the level of creativity. This is one of potential aspects of parametric design. Exploring design strategies in parametric design contributes to its effective use.

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.

title A Sensor based context-aware inference algorithm for ubiquitous residential environments
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 93-102
summary As the development of a computer and the internet have changed social and economic activities related with the human life style. According to these changes, ubiquitous residential environments have been discussed. This paper presents ways of interpreting the situation in association with human interaction with residential environments. This paper deals with various operations of architectural components based on a sensor based context awareness. The methods adopted in this paper for suitable services corresponding to residents’ requirements are Pattern Driven Inference(PDI), Rule Driven Inference(RDI) and Case Driven Inference(CDI). In summary, this paper describes processes how services are provided. And Context based residential management is main research issue.

title RFID applications in a building project
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 700- 712
summary As a new paradigm for construction in the ubiquitous era, IT Technology like RFID is an emerging issue in the building industry. For the purpose of RFID technology application in the building industry, this research suggests the Information Lifecycle Management using RFID technology in apartment building project and deals with the context-aware scenario for RFID technology application. The final objective of the research intends to develop the RFID application for the construction industry. From the tagging nodes at the material manufacture stage to the reading nodes at the end stage of the construction process, the flow of the RFID information deals with the synthetic application connecting physical construction material with electronic RFID information for the management. Furthermore, we suggest how to systematize, distribute and manage the construction material with the Information Lifecycle Management.
