title	Facilitating Architect-Client Communication in the Pre-design Phase
doi	https://doi.org/10.52842/conf.caadria.2021.2.071

summary	The process of architects exploring the program with clients often take place through face-to-face oral discussions and visual aids, such as photos and sketches. Our research focuses on two communication mediums: language and sketch. We employ machine learning techniques to assist architects and clients to improve their communication and reduce misunderstandings. We have trained a Naive Bayesian Classifier machine, the language assistant (LA), to classify architectural vocabularies with associations to design requirements. In addition, we have trained a Generative Adversarial Network, the sketch assistant (SA), to generate photo quality images based on architects' sketches. The language assistant and sketch assistant combined can facilitate architect-client communication during the pre-design stage.

title	Expanding the Methods of Human-VR Interaction (HVRI) for Architectural Design Process
doi	https://doi.org/10.52842/conf.caadria.2021.2.173

summary	The emergence of virtual reality technology now brings the possibility of new design methods. Virtual reality technology allows architects to feel space better and express design ideas more intuitively. With the interactive perception equipment and VR glasses, geometric shapes can be created and modified in a virtual environment, replacing the mouse and keyboard to complete the creation of space in the early stage of the design process. At present, the application of virtual reality in the architectural design process has some problems include unnatural interaction, low accuracy, high work cost. This paper will summarize the interactive methods of virtual reality technology in various current cases and compare the input and output of the device by analyzing the matrix method. We can explore interactions that are beneficial to architectural design. Using these interactive methods, we can expand the interface relationship between humans and the virtual environment.

title	Asymptotic Building Envelope - combining the benefits of asymptotic and principal curvature layouts
doi	https://doi.org/10.52842/conf.caadria.2021.1.341
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 341-350
summary	This paper presents current research on low-cost, high-performance doubly curved building envelopes that benefit from a curvilinear layout along an isothermal web on minimal surfaces. We investigate the geometric symbiosis of an elastic lamella mullion system that follows the asymptotic curves combined with panelization strategies along the principal curvature lines in order to simplify fabrication and enhance the structural performance. We present a digital and physical setup of a full-scale prototypical asymptotic façade substructure. In collaboration with the construction industry, we evaluate the complete design and construction process, including digital modeling, fabrication planning, computer-aided manufacturing and logistics, prefabrication, and assembly. Both digital and physical prototypes are used to investigate cladding solutions. Our studies are specifically looking at developable-elastic and planar-rigid tessellations, which utilize a principal curvature layout. We conclude by highlighting flat-sheet fabrication, high structural resilience, and assembly time and tolerances, as primary potentials and challenges of this design strategy.

title	Research on Self-Formation Wind Tunnel Platform Design based on dynamic gridding mechanical devices
doi	https://doi.org/10.52842/conf.caadria.2021.2.669

summary	Nowadays, climate problems, such as urban ventilation, heat island effect are becoming increasingly serious. Performance-oriented buildings that respond positively to the environment are constructing a sustainable future of the living environment. This research introduces an autonomous Self-Formation Wind Tunnel (SFWT) platform based on 120 dynamic grid mechanical devices, and its building cluster morphology generation workflow in the conceptual design stage, for the rapid and mass formation experiments. The Self-formation wind tunnel plat-form, which has the advantages of both perceptive and real-time data, is able to use the techniques of machine learning to provide a new design paradigm, from environmental performance to physical morphology.

title	Automatic Generation of Signboards in Large-Scale Transportation Building Driven by Passengers' Paths
doi	https://doi.org/10.52842/conf.caadria.2021.1.011
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 11-20
summary	The signage design of any large-scale transportation building is vital to its passengers wayfinding experiences. Firstly, a set of passengers paths should be re-designed by signage designers according to the latest requirements, which always deviates from the initial ones in large-scale projects or inevitably updates during a long-term running. Afterwards, the path design has to be transformed into the layout and content of signboards manually. It is a time-consuming and error-prone process. This study introduces a human-computer hybrid workflow keeping the flexible path design in the hands of designers and leaving the following procedures to an algorithm, which automatically generates signboard contents ready for construction. It is proved efficient with more than 3000 signboards in the project of PVG Airport, Shanghai. Furthermore, the designer got an opportunity to optimize his path design through various alternatives, which impossible traditionally.
