Hologram Walk: Digital Participatory Design Platform for Architectural and Urban Design Project

To develop innovative solutions to urban challenges via a participatory design involving collaboration among all stakeholders—government authorities, designers, businesses, and local communities—technological applications that facilitate interactions must be integrated from the earliest stages of urban development projects. However, such collaboration is often hampered by the lack of effective platforms for communication and exchange, particularly given the difficulty of achieving consensus between experts and non-experts. From another perspective, hologram technology remains relatively underexplored and underutilized in the fields of architecture and urban design despite being a highly promising immersive technology. This study applied hologram technology and computer vision to create an interactive digital platform that enhances participatory design among stakeholders, which is called hologram walk. The proposed system was implemented on a university campus in Vinh Long, Vietnam, for its renovation project. This technology-driven platform allows users to experience and interact with the design proposal, communicate their opinions and needs, and enables the design team to make responsive adjustments. This proposed platform optimizes collaboration, fosters innovative designs outcomes, and can be easily replicated in future architectural and urban projects.
