This paper discusses the potential derived by developing a sketching interface to achieve an intuition-oriented design process for beginners, focusing on fabrication. Using experiments and a questionnaire, we evaluate both the method developed and the change in the consciousness of participation in full-scale 3D (Three Dimensional) design. A specific feature of the developed sketching interface is that it is not fully packaged; it means designers can modify and customize a tool to their needs. However, there was no difference between the sketching interface and ordinary 3D CAD (Computer-Aided Design) in increasing the motivation to use computers to fabricate; including a customizable feature (not fully packaged) could open up the possibilities of increasing motivation for the subjects to participate in the fabrication. The experiment results demonstrated that the sketching interface input system has equivalent reproducibility to existing 3D CAD, and even beginners can intuitively and immediately realize fabrication.

This paper presents insights into the opportunities and barriers for using augmented reality (AR) and virtual reality (VR) in the architecture, engineering and construction (AEC) industry by contextualizing how their adoption is leveraged in practices. Based on a review of literature, a qualitative study using semi-structured interviews was conducted with thirteen participants from AEC industries between five and thirty years of experience. Interviews were conducted face-to-face and virtually using questions focusing on participants’ experiences, perceptions of, and opinions about the use of AR/VR in AEC practice. Qualitative dissemination of key insights highlighted immediate and future possibilities for AR/VR, with current limitations that require future investigation from a user-centred perspective. Suggesting a XR-PACT framework, this paper frames key directions for future research to address current limitations and explore new opportunities that positively impact architecture and other professions, communities of building users.

098 – Validating Game Engines as a Quantitative Daylighting Simulation Tool

This study aims to investigate the accuracy of representing daylit spaces using game engine-based rendering techniques, compared to validated benchmark renderers and real-life measurements. Two daylit case studies- reflecting different complexity levels and spatiotemporal settings- were rendered in a game engine using a traditional rendering technique and real-time raytracing. Illuminance levels at selected points were measured in Unreal Engine and were compared to those calculated in a validated light simulation tool and an illuminance meter for the simplified and complicated case studies, respectively. In both cases, traditional technique cited a high variance in illuminance levels compared to the references. In the simplified model, real-time ray tracing showed the lowest average error compared to the validated simulation results. In the complicated model, the average error of such technique was close to that of the validated simulation, compared to the actual illuminance measurements. This study illustrates the added benefits of using real-time ray tracing in game engines over traditional ray tracers to offer an immersive and interactive experience of virtual daylit spaces, without sacrificing the quantitative accuracy of the simulated luminous environments.

Muhammad is currently a Ph.D. candidate and a member of the Architectural Morphology Lab at the Graduate School of Engineering, Osaka University. His doctoral research focuses on optimizing human-centered daylight performance in indoor environments at early design stages, where he aims to introduce a set of unified daylight performance metrics and approaches that consider both subjective and physical qualities of daylight.

312 – Participatory AR: A Parametric Design Instrument

CAAD research has frequently investigated the realm of public participation in large scale urban design re-development. Cultural shifts have created a need to involve the end-users in these activities, and CAAD is quick and plentiful to offer solutions, yet, the recurring problem lies with the lay-person not being able to interpret information effectively and be able to take part in the process of design proactively. To date, much-existing research predominantly focuses on the development of designs in urban settings using high tech devices such as the Hololens, that fundamentally require a high level of expertise, or an experienced ‘guide’, to help navigate or create within these environments. Our paper presents a novel application based on real-time-virtual-engines and XR. The work discusses the role that tangible user interfaces (TUI) can play in the engagement of the lay-person in the design process. In the paper, we describe how the integration of interaction design (IxD) and augmented reality (AR) offer new opportunities due to the extending web of availability of barrier-free technologies to better include lay-persons as active participants in the design process.

David Silcock completed his 5th year of architectural studies in 2020, focusing on the role that tangible user interfaces can play in participatory urban design. Since then, he has gone on to work at the software company Trimble, working in their Computational Design Group in Wellington.

331 – Big Data Bugs: Investigating the Design of Augmented Reality Applications for Museum Exhibitions

This paper presents a reflection on the co-design approach taken for designing a web-based and smartphone-augmented reality (AR) application (app) for a local museum exhibit on geo-located data for entomology specimens. The AR app allows visitors to spatially visualise insect specimens in-situ and view more detailed information through their own devices. The design of the app was guided by continuous input from curators of the museum to ensure it met their requirements. The contribution of this paper is two-fold: (1) design recommendations for AR apps created for museum exhibitions, which are derived from a focus group session with museum curators; and (2) considerations for co-designing AR apps in museum contexts, based on a reflection of the design process. This paper details the iterative co-design process that was adopted for the ‘Big Data Bugs’ project and presents a short summary of results deriving from a focus group testing with museum curators.

Dr. Globa is a researcher, academic and designer working in the field of architecture, with the strong research interests in algorithmic design, advanced manufacturing and interactive immersive environments.
