Digital Twin System for Smart Buildings Integrated with Blockchain and Mixed Reality Technology

Abstract

The integration of 3D innovation, Mixed Reality (MR), and blockchain in smart buildings has revolutionized the IoT sector. Visualization using 3D technology and immersive interfaces allows users to control and interact with devices within smart building environments. Users can use hand gestures or controllers in a 3D environment to adjust lighting, monitor energy consumption, or manage other smart devices. When combined with MR, the capabilities of 3D technology are enhanced with virtual elements overlaying onto the real-world environment. Within smart buildings, MR can visualize real-time sensor data, display device statuses, and provide intuitive visual feedback. The integration of blockchain in this ecosystem adds layers of security, transparency, and trust by securely recording and verifying device data, control commands, and user interactions. Blockchain technology enables secure peer-to-peer communication and smart contracts for automated device interactions and control. User testing results for controlling smart buildings with Mixed Reality (MR) technology showed high user satisfaction with an average score of 4.48. Users appreciated the performance and functionality of the system, as well as the new experience provided by the natural and immersive MR interface for interacting with smart building controls.
