Weather Synchronization in Digital Twin Environments for Shared VR Experience Using Commercial Metaverse Platforms

Digital twin technology creates bidirectional synchronization between physical and virtual environments, yet current implementations fail to provide authentic environmental experiences that enhance user presence in shared virtual spaces. While digital twin environments using commercial metaverse platforms for IoT sensor data visualization have been proposed, translating environmental information into meaningful sensory experiences remains largely unexplored, particularly lacking approaches for weather conditions that significantly influence spatial perception. We developed a weather synchronization system that integrates real-time environmental data from ``The GEAR'' smart building with the Cluster metaverse platform, enabling shared VR experiences with authentic atmospheric immersion. Our system processes temperature, humidity, precipitation, wind speed, and solar radiation measurements to generate corresponding virtual environmental effects including dynamic sky rendering, precipitation particles, and ambient audio modulation. Performance evaluation demonstrated practical response times of 0.8-1.0 seconds for weather data transmission and reflection in the virtual environment. This work establishes a foundation for seamless physical-digital space integration, potentially enhancing remote collaboration efficiency and facilitating more dynamic discussions in shared virtual workspaces.

Implementation and Application of Multi-Format 3D Data Integration in a Cross-Device Commercial Metaverse Platform

Traditionally, specialized 3D design data, such as BIM and CAD, have been accessible only to a select group of experts, creating significant barriers that prevent general users from participating in decision-making processes. This paper provides a systematic overview of practical insights for utilizing 3D data in industrial and architectural domains by presenting implementation cases of the industrial metaverse on Cluster, a commercial cross-device metaverse platform. This paper analyzes the characteristics and constraints of major data formats in the industrial and architectural fields and organizes integration workflows for the metaverse. Through application cases utilizing 3D data across multiple domains, we present practical examples of collaborative decision-making support enabled by the fusion of metaverse and digital twin technologies. Specifically, we demonstrate that multi-device access and simultaneous multi-user participation capabilities foster democratic environments in the industrial metaverse, which are challenging to achieve with conventional, expert-dependent systems.

Development of Digital Twin Environment through Integration of Commercial Metaverse Platform and IoT Sensors of Smart Building

The digital transformation of smart cities and workplaces requires effective integration of physical and cyber spaces, yet existing digital twin solutions remain limited in supporting real-time, multi-user collaboration. While metaverse platforms enable shared virtual experiences, they have not supported comprehensive integration of IoT sensors on physical spaces, especially for large-scale smart architectural environments. This paper presents a digital twin environment that integrates Kajima Corp.'s smart building facility "The GEAR" in Singapore with a commercial metaverse platform Cluster. Our system consists of three key components: a standardized IoT sensor platform, a real-time data relay system, and an environmental data visualization framework. Quantitative end-to-end latency measurements confirm the feasibility of our approach for real-world applications in large architectural spaces. The proposed framework enables new forms of collaboration that transcend spatial constraints, advancing the development of next-generation interactive environments.
