summary	In the information age, the attention to architectural design has gradually shifted from spatial aesthetics to the human's spatial experience. The situation of human perception becomes essential feedback information that designers can use to improve the design schemes. This research proposes an auxiliary method for pre-evaluating the architectural design goals and providing recommendations for architects to optimize the scheme. Specifically, by aggregating and quantitative analyzing electrophysiological signals and eye-tracking data, this research obtained the user's spatial perception with little effect of subjective consciousness as their feedback on the architectural environment. We took the campus outdoor space of an International School of Design as the research sample. By combining the architect's design concept and objectives, we constructed the contrast spatial schemes in virtual reality (VR) for users to experience and analyzed the usability of this method when pre-evaluate design objectives in a practical project.

summary	During the COVID-19 pandemic situation, educational institutions were forced to conduct all academic activities in distance learning formats, including the architecture program. This act barred interaction between students and supervisors only through their computers screen. Therefore, in this study, we explored an opportunity to utilize virtual reality (VR) technology to help students understand and evaluate design outcomes from an architectural design studio course in a virtual environment setting. The design evaluation process is focused on building affordance and user accessibility aspect based on the design objectives that students must achieve. As a result, we developed a game-engine based VR system called VRDR for evaluating design studio outcomes modeled as Building Information Modeling (BIM) models.

summary	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 contextualising 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.

title	Immersive VR Environment for Construction Detailing Education: BIM Approach
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 114-128
summary	According to literature in education, adults learn best when learning is active, self-directed, problem-based, and relevant to their needs. In Building Construction Education, construction site visits provide students with real-life practical experience which are considered an extension for classroom. Nevertheless, it is challenging to integrate construction site visits regularly during the academic semester with respect to the class specific needs. Virtual Reality as an interactive immersive technology may facilitate virtual construction site that meets the learning needs where students can explore and build in a real scale environment. The proposed VR environment is an HMD VR platform for construction detailing that provides experiential learning in a zero-risk environment. It builds on integrating VR technology as a medium and Building Information Modeling (BIM) as a repository of information. This work discusses the proposed environment curricular unit prototype design, implementation, and validation. System usability and immersion are assessed both qualitatively and quantitatively. After considering the feedback, The VR environment prototype is then validated on the level of learning outcomes, providing the evidence that it would enhance students’ engagement, motivation and achievement accordingly.

title	Built-In Immersive VR Technology for Decision-Making in Design and Simulation of a Flexible Shading Device
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 190-200
summary	This paper discusses the potential offered by Virtual Reality (VR) and accompanied gesture-based devices as tools for architectural design and simulation. This is done by outlining a workflow and by demonstrating an experimental study for the development of an interactive, flexible and parametric shading device consisting of bending-active wooden strips. More specifically, the project focuses on the relationship between physical inputs acquisition and virtual experience of two users in space. Through the use of Kinect and VR headset, the first user is responsible to check and control the shading system regarding the shape and sun direction. The aim is to create configurations that serves his/her shading needs by moving his/her hand in order to hide the sun in a game like procedure until satisfactory shading is acquired. The second user, through the use of a leap motion sensor and a projection screen, is able to check and control the efficiency of structure in terms of bending behavior and environmental impact, also in a loop of possibilities. Using the thump and pointer fingers he/she controls the bending behavior by watching a screen that shows in different colours the bending factor of each element. At the same time, the distance between his/her hands controls the number of elements in order to achieve the optimal rate between material consumption and shading. The two users can intervene sequentially or concurrently during the process. A series of investigations related to shading rate and bending behavior as well as minimum material consumption leading to lower environmental impact are conducted. This attempts to offer useful conclusions as regard the potential application of immersive VR technology as mechanism for decision-making in architecture and simulation but also in the fabrication of the suggested shading device.

title	The Fourth Virtual Dimension - Stimulating the Human Senses to Create Virtual Atmospheric Qualities
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 213-222
doi	https://doi.org/10.52842/conf.caadria.2021.2.213
summary	In a move away from the ubiquitous ocular-centric Virtual Environment, our paper introduces a novel approach to creating other atmospheric qualities within VR scenarios that can address the known shortcoming of the feeling of disembodiment. In particular, we focus on stimulating the human bodys sensory ability to detect temperature changes: thermoception. Currently, users perceptions of a 3D virtual environment are often limited by the general focus, in VR development for design, on the two senses of vision and spatialised audio. The processes that we have undertaken include developing individual sensory engagement techniques, refinement of sensory stimuli and the generation of virtual atmospheric qualities. We respond to Pallasmaas theoretical stance on the evolution of the human senses, and the western bias of vision in virtual engine development. Consequently, the paper investigates the role our senses, outside of the core five senses, have in creating a fourth virtual dimension. The thermoception dimension is explored in our research. A user can begin to understand and engage with space and the directionality within a virtual scenario, as a bodily response to the stimulation of the bodys thermoception sense.

title	Beauty is in the Eye of the Beholder - Improving the Human-Computer Interface within VRAD by the active and two-way employment of our visual senses
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 355-364
doi	https://doi.org/10.52842/conf.caadria.2021.2.355
summary	Whether it is via traditional methods with pen and paper or contemporary techniques such as 3D digital modelling and VR drawing, the eye typically plays a mostly passive or consuming role within the design process. By incorporating eye-tracking deeper within these methods, we can begin to discern this technologys possibilities as a method that encompasses the visual experience as an active input. Our research, however, developed the Eye-Tracking Voxel Environment Sculptor (EVES) that incorporates eye-tracking as there design actor. Through EVES we can extend eye-tracking as an active design medium. The eye-tracking data garnered from the designer within EVES is directly utilised as an input within a modelling environment to manipulate and sculpt voxels. In addition to modelling input, eye-tracking is also explored in its usability in the Virtual Reality User Interface. Eye-tracking is implemented within EVES to this extent to test the limits and possibilities of eye-tracking and the Human-Computer Interface within the realm of Virtual Reality Aided Design.

summary	The COVID-19 pandemic has made most schools, universities, and gathering spaces fully virtual. Commonly used communication platforms such as Zoom, Skype, and Microsoft Teams are limited in recreating physical interactions and offer mostly static interfaces with limited occasions for spontaneous encounters. This project creates a space that seeks to address this issue, first through the digitization of familiar physical spaces, and then through their augmentation via WebXR technologies[1]. A gamification strategy is adopted, where users can virtually learn, collaborate and socialize through personalized avatars within a dynamic and multi-sensorial digital environment. In this paper, we present a completed prototype that is currently being tested at the Harvard Graduate School of Design. The school of architecture has been digitized and experientially augmented thanks to an asymmetrical system that offers rich modalities of interaction through different platforms. The project builds upon the wide experiential potential of digital platforms, otherwise not possible in reality, and implements a customized multi-modal user interface (Reeves et al. 2004).

title	Optimizing container housing units for informal settlements - A parametric simulation & visualization workflow for architectural resilience
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. 51-60

summary	In rapidly growing cities like Dhaka, Bangladesh, sustainable housing in urban wetlands and slums present a challenge to more affordable and livable cities. The Container Housing System (CHS) is among the latest methods of affordable, modular housing quickly gaining acceptance among local stakeholders in Bangladesh. Even though container houses made of heat-conducting materials significantly impact overall energy consumption, there is little research on the overall environmental impact of CHS. Therefore, this study aims to investigate the performance of CHS in the climatic context of the Korail slum in Dhaka. The paper proposes a building envelope optimization and visualization workflow utilizing parametric cluster simulation modeling, multi-objective optimization (MOO) algorithms, and virtual reality (VR) as an immersive visualization technique. First, local housing and courtyard patterns were used to develop hypothetical housing clusters. Next, the CHS design variables were chosen to conduct the MOO analysis to measure Useful Daylight Illuminance and Energy Use Intensity. Finally, the prototype was integrated into a parametric VR environment to enable local stakeholders to walk through the clusters with the goal of generating feedback. This study shows that the proposed method can be implemented by architects and planners in the early design process to help improve the stakeholders understanding of CHS and its impact on the environment. It further elaborates on the implementation results, challenges, limitations of the parametric framework, and future work needed.

summary	Architectural Education faces limitations due to its tactile approach to learning in classrooms with only 2-D and 3-D tools. At a higher level, virtual reality provides a potential for delivering more information to individuals undergoing design learning. This paper investigates a hypothesis establishing grounds towards a new research in Building Information Modeling (BIM) and Virtual Reality (VR). The hypothesis is projected to determine best practices for content creation and tactile object virtual interaction, which potentially can improve learning in architectural & construction education with a less costly approach and ease of access to well-known buildings. We explored this hypothesis in a step-by-step game design demonstration in VR, by showcasing the exploration of the Farnsworth House and reproducing assemblage of the same with different game levels of difficulty which correspond with varying BIM levels of development (LODs). The game design prototype equally provides an entry way and learning style for users with or without a formal architectural or construction education seeking to understand design tectonics within diverse or cross-disciplinary study cases. This paper shows that developing geometric abstract concepts of design pedagogy, using varying LODs for game content and levels, while utilizing newly developed features such as snap-to-grid, snap-to-position and snap-to-angle to improve user engagement during assemblage may provide deeper learning objectives for architectural precedent study.

title	Experiential Teaching-learning Tools: Critical Study of Representational Media and Immersion in Architecture
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 475–488
summary	The use of Virtual Reality (VR) in teaching-learning process of design, theory and history of architecture has increased in terms of virtual tours. A preliminary study of techniques and capabilities of Immersive Virtual Reality (IVR) systems allowed us to establish that the immersive and interactive virtual experience facilitates the perception and enhancement of spatial qualities. In addition, it facilitates analysis since it promotes observation and the development of spatial thinking. However, the use of this medium as a tool for analysis is less frequent. Therefore, in this research we comparatively evaluate the impact that VR has on such a task. We developed an analysis instrument using experiential learning cycles that was tested with students in control and experimental groups. As a result, we found that the experience of inhabiting facilitates integration of fundamental concepts, allowing empirical evaluation of architecture and streamlining communication in the classroom as an active learning strategy.

doi	https://doi.org/10.52842/conf.ecaade.2021.2.323
summary	The paper presents a concept model of a modular exhibition that is designed to function as a museum in the physical environment and as an archive of architectural projects in the virtual. A design method based on shape grammars and inspired by the Bauhaus teaching, has been used to generate both the museum spaces and the archive which expands endlessly as the acquisition of architectural exhibits keeps increasing. Specifically, rules that control the geometric organization, tectonic expression and linear or radial expansion of a modular assembly of interlocking physical or virtual spaces, leading to various self-similar spatial patterns, have been developed. Several scenarios of the visitors' interaction with the exhibits and the museum's space with the use of VR and AR have been explored. In the actual museum scenario, physically present visitors can interact with the exhibits which are enriched with digital information. In the case of the archive, the Unity platform is used for the development of a virtual experience of the visitor who interacts with the expanding space and exhibits in a purely immersive manner.

summary	Creating a visual 3D model is a vital part of the architectural design process. In architectural scenes, immersion is important to perceive the connection between various aspects. The general interaction cannot meet the needs of immersion. The immersion and interaction of virtual reality (VR) allows architects to feel and design spaces better. However, VR is currently mainly used only for visualization and walkthrough of the architectural space. The design process is still done using modeling software. This paper proposes a method of architectural design in virtual reality, allowing designers to experience the model created in real-time and improve the design. The use of visual mesh positioning and ray limits can help users create accurate architectural models. The paper also applied the innovative design method to the participatory design process and showed that architectural design in virtual reality can improve design quality and better meet the needs of users.

summary	The research in human-computer interaction (HCI) has been ongoing for years until present-day to observe how humans interact with computers and digital technologies. Then comes the development of virtual reality (VR), one where it allows users to be immersed in the virtual environment for various kinds of experiences. This paper takes a close reference to the research method in HCI and brings the examination to the context of VR to understand the user behavior towards human-VR interaction (HVRI). A workshop is done based on the new HVRI method, and students are given the task to explore what are the elements of architecture that can be interacted and how they can be performed in the immersive environment. This paper will describe the HVRI designed and analyze how the new interaction method helps to bring about closer relationships between the human and the virtual model beyond just visualization.

title	Effect of Immersive VR on Communication Patterns in Architectural Design Critiques

doi	https://doi.org/10.52842/conf.ecaade.2021.1.123
summary	Immersive Virtual Reality (iVR) systems hold a promise to affect design behavior by allowing users to experience presence, as they are embodied in the digital display. However, the lack of research articulating how embodiment enabling media change design behavior limits integrating iVR systems in design pedagogy with a well-defined framework. This paper presents the preliminary results from a case study of a work in progress comparing the communication patterns of critique sessions in an architecture studio in two kinds of media: iVR and non-immersive desk-crits. We employed protocol analysis methods to track the distribution of conversational turns and the first occurrence of design issues emerging over the different media. Results show that compared to non-immersive critiques, the iVR had a lower number of conversational turns and an increase in the first occurrence generated by students, indicating support in a learner-centered activity. Elucidating the effect of the communication medium on design behavior provides an empirical foundation for its inclusion in a design theory that encapsulates embodied cognition.

summary	Operating room design is a complex planning task. In order to jointly find the best solution, specialists from numerous professions are involved in the planning process, since e.g. equipment layout and airflow is crucial for optimal surgical procedures. For a better and more informed discussion, and thus better optimization and firm decisions, we have developed a method linking BIM (Building Information Modelling), VR (Virtual Reality), AR (Augmented Reality), CFD (Computational Fluid Dynamics) simulation, and a tangible user interface, so that freely configurable layouts can be tested interactively, be discussed, and optimized both in model and 1:1 scale already in early planning phases. This method has been applied to a hospital design with 33 new operating rooms, differing in sizes as well as layouts according to the different types of operations.

This paper proposes a brand-new interaction design system for remote online virtual tourism based on bicycle riding behavior and projection mapping technologies. Through the user experience evaluation experiments of this system, the research found that this interactive system can effectively improve the realism and sense of the presence of the virtual environment. It can also enhance the delectation and satisfaction of the virtual tour. At the same time, this system can reduce the simulator syndrome which plays as a common problem in the traditional virtual tour experience.

title	Inside the Matrix: Immersive Live Coding for Architectural Design
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 2, 174–189
summary	Algorithmic Design (AD) uses computer programs to describe architectural models. These models are visual by nature and, thus, greatly benefit from immersive visualization. To allow architects to benefit from the advantages of Virtual Reality (VR) within an AD workflow, we propose a new design approach: Live Coding in Virtual Reality (LCVR). LCVR means that the architect programs the design while immersed in it, receiving immediate feedback on the changes applied to the program. In this paper, we discuss the benefits and impacts of such an approach, as well as the most pressing implementation issues, namely the projection of the programming environment onto VR, and the input mechanisms to change the program or parts of it. For each, we offer a critical analysis and comparison of the various solutions available in the context of two different programming paradigms: visual and textual.

summary	This paper updates on the developments in the use of low-cost Virtual Reality devices for Architectural design. The authors established a workflow using the gaming software "Unity" to prepare geometry for virtual environments and developed interfaces for a more natural movement inside the virtual world. We will give a summary on the old experiments and explain about our latest develoments in refining the workflow and the interfaces within a new setting. Architects teamed up with civil engineers with a focus on computer science. Due to new hardware developments, we could change the systems from wired to wireless and added several funktions within the overall aim to keep it simple and affordable.

title	A Motion Vector Visualization Method on a Virtual Reality Screen - Preventing virtual reality sickness for architectural investigation

summary	In the age of mass customization, virtual reality (VR) allows users to virtually visualize architecture from any viewpoint they prefer and to examine the design. It is important to evaluate the movement of the virtual camera to guarantee the quality of VR content in addition to preventing VR sickness. The development of rendering methods to visualize the speed of VR cameras has begun. However, the only absolute velocity values are insufficient because the amount of movement of objects close to the camera is large, and that of distant objects is small. Therefore, this research aims to develop a visualization method of relative velocities known as motion vectors on a VR screen. A prototype of a new rendering technique has been implemented and successfully applied to a VR application for design review of a complex building. There are two rendering methods to display a gradient in RGB colors and to give a motion blur effect. This function allows VR creators to understand where in the virtual world VR sickness is likely to occur.
