Abstract
To effectively use augmented reality (AR) technology for end-user involved design collaboration, it is necessary to ensure the effectiveness of the AR system from the end-user’s perspective. However, most efforts have mainly focused on technological development, and as such, limited attention has been paid to the end-user’s application of the AR system. Therefore, this study investigates how the AR system affects architectural design review based on the user’s perspectives. Three different display systems presenting a 3D model including a 2D screen, VR, and AR were tested, and a total of 76 participants evaluated visual presentation quality, perceived acceptability, and user experience according to their usage of the visualization platform types during the design review activities. Compared to other systems, the results indicated that the AR system could be more effective in reviewing the visual elements of a building. Furthermore, AR showed the highest ratings for acceptance level and user experience. The innovation provided by AR created a positive user experience, despite its remaining challenges to be resolved in terms of functionality. Since it is expected that the use of AR can be promoted by overcoming certain technological limitations, this study contributes to guiding AR system applications for end-users involved in the design review process.
Highlights
Architectural design is a continuous process of meeting a client’s needs through collaboration [1].As acquiring reliable feedback from end-users for the assessment of design options would be beneficial for the overall quality of the design and end-user satisfaction, the design review process involves designers and engineers and end-users [2,3]
The color of the 3D building information modeling (BIM) model was best presented in virtual reality (VR) and subjects felt a better sense of scale with the 2D screen compared to other systems
The user experience of the augmented reality (AR) system was evaluated through a user experience questionnaire (UEQ) questionnaire
Summary
Architectural design is a continuous process of meeting a client’s needs through collaboration [1].As acquiring reliable feedback from end-users for the assessment of design options would be beneficial for the overall quality of the design and end-user satisfaction, the design review process involves designers and engineers and end-users [2,3]. Design review with end-users requires a continuous iterative process of sharing building information, and the client is generally provided with project-relevant information by the design team in the form of drawings or models. During this information sharing, finely visualized building information could improve the understanding of design concepts and ideas and facilitate the effectiveness of communication between participants [4]. To support information delivery and management, building information modeling (BIM) is rapidly being adopted by project participants. Three-dimensional (3D) models allow non-technical parties to understand designs more quickly compared to 2D drawings [5]. The recent use of virtual reality (VR) and augmented reality (AR) technologies are gaining considerable attention as a new means of visualization platform
