IM-MetaLAB: the first digital laboratory for teaching the fundamental concepts of instrumentation and measurement in metaverse

This paper presents the Instrumentation and Measurements Metaverse Laboratory (IM-MetaLAB), an immersive virtual laboratory developed within the metaverse to support hands-on training in instrumentation and measurement. Unlike previous Augmented Reality (AR)/Virtual Reality (VR)-based solutions or simulated environments, IM-MetaLAB integrates real laboratory instruments through digital twins that communicate in real time with their physical counterparts using Standard Commands for Programmable Instruments (SCPI) commands over Message Queuing Telemetry Transport (MQTT). The platform supports synchronous and asynchronous learning modes, promotes collaborative activities among students, and replicates real-world laboratory procedures in a safe and accessible 3D environment. A representative case study, focused on root means square (RMS) voltage measurement, demonstrates the system’s capabilities in executing full experimental workflows. Comparative analysis with traditional, online, and remote lab-based teaching methods was conducted using key performance indicators such as student engagement, completion rate, and examination scores. The results indicate that IM-MetaLAB significantly improves learning outcomes and practical proficiency. Ongoing work addresses scalability and cost-reduction through the implementation of a custom hardware interface.
