Daraiseh, N. M., Tang, M., Macaluso, M., Aeschbury, M., Bachtel, A., Nikolaenko, M., … Vaughn, A. (2025). Virtual Reality Training to De-escalate Patient Aggressive Behavior: A Pilot Study. International Journal of Human–Computer Interaction, 1–16. https://doi.org/10.1080/10447318.2025.2576635

Abstract
Despite intensive crisis de-escalation training, psychiatric staff continue to face high injury rates from aggressive patient interactions (APIs). New approaches are needed to enhance the application of effective strategies in managing APIs. This study explored the efficacy and feasibility of VR training for psychiatric staff in recognizing and selecting appropriate de-escalation interventions. A quasi-experimental design with psychiatric staff (N = 33) tested the effectiveness and feasibility of VR training depicting a common API interaction. Effectiveness was assessed through pre-post comparisons of the Confidence in Coping with Patient Aggression (CCPA) survey, correct answer percentages, response times, and attempt success rates. Feasibility was indicated by mean scores above ‘neutral’ on usability, presence, and learner satisfaction surveys. Results showed significant improvements in response times and confidence (p<.0001), with over 75% of participants rating the training positively. VR training is effective and feasible for enhancing de-escalation skills, offering a promising approach for psychiatric facilities.

Metaverse and Digital Twins in the Age of AI and Extended Reality

Tang, Ming, Mikhail Nikolaenko, Ahmad Alrefai, and Aayush Kumar. 2025. “Metaverse and Digital Twins in the Age of AI and Extended Reality” Architecture 5, no. 2: 36. https://doi.org/10.3390/architecture5020036

 

This paper explores the evolving relationship between Digital Twins (DT) and the Metaverse, two foundational yet often conflated digital paradigms in digital architecture. While DTs function as mirrored models of real-world systems—integrating IoT, BIM, and real-time analytics to support decision-making—Metaverses are typically fictional, immersive, multi-user environments shaped by social, cultural, and speculative narratives. Through several research projects, the team investigate the divergence between DTs and Metaverses through the lens of their purpose, data structure, immersion, and interactivity, while highlighting areas of convergence driven by emerging technologies in Artificial Intelligence (AI) and Extended Reality (XR).This study aims to investigate the convergence of DTs and the Metaverse in digital architecture, examining how emerging technologies—such as AI, XR, and Large Language Models (LLMs)—are blurring their traditional boundaries. By analyzing their divergent purposes, data structures, and interactivity modes, as well as hybrid applications (e.g., data-integrated virtual environments and AI-driven collaboration), this study seeks to define the opportunities and challenges of this integration for architectural design, decision-making, and immersive user experiences. Our research spans multiple projects utilizing XR and AI to develop DT and the Metaverse. The team assess the capabilities of AI in DT environments, such as reality capture and smart building management. Concurrently, the team evaluates metaverse platforms for online collaboration and architectural education, focusing on features facilitating multi-user engagement. The paper presents evaluations of various virtual environment development pipelines, comparing traditional BIM+IoT workflows with novel approaches such as Gaussian Splatting and generative AI for content creation. The team further explores the integration of Large Language Models (LLMs) in both domains, such as virtual agents or LLM-powered Non-Player-Controlled Characters (NPC), enabling autonomous interaction and enhancing user engagement within spatial environments. Finally, the paper argues that DTs and Metaverse’s once-distinct boundaries are becoming increasingly porous. Hybrid digital spaces—such as virtual buildings with data-integrated twins and immersive, social metaverses—demonstrate this convergence. As digital environments mature, architects are uniquely positioned to shape these dual-purpose ecosystems, leveraging AI, XR, and spatial computing to fuse data-driven models with immersive and user-centered experiences.

Abstract

The recent advancement in Large Language Models (LLMs) has significantly transformed the field of natural data interpretation, translation, and user training. However, a notable gap exists when LLMs are tasked to assist with real-time context-sensitive machine data. The paper presents a multi-agent LLM framework capable of accessing and interpreting real-time and historical data through an Industrial Internet of Things (IIoT) platform for evidence-based inferences. The real-time data is acquired from several legacy machine artifacts (such as seven-segment displays, toggle switches, and knobs), smart machines (such as 3D printers), and building data (such as sound sensors and temperature measurement devices) through MTConnect data streaming protocol. Further, a multi-agent LLM framework that consists of four specialized agents – a supervisor agent, a machine-expertise agent, a data visualization agent, and a fault-diagnostic agent is developed for context-specific manufacturing tasks. This LLM framework is then integrated into a digital twin to visualize the unstructured data in real time. The paper also explores how LLM-based digital twins can serve as real time virtual experts through an avatar, minimizing reliance on traditional manuals or supervisor-based expertise. To demonstrate the functionality and effectiveness of this framework, we present a case study consisting of legacy machine artifacts and modern machines. The results highlight the practical application of LLM to assist and infer real-time machine data in a digital twin environment.

Abstract

The significance of design’s cross-disciplinary nature has increased alongside technological advancements as emerging technologies present new opportunities and challenges for complex socio-technical systems. Systems thinking has drawn attention to design as a holistic approach to tackling complex systems by examining the interrelationships between elements. This also necessitates cross-disciplinary collaboration to address the multifaceted nature of the problems comprehensively. These aspects of systems thinking further emphasize its importance in design education to help navigate the current era of technological innovation. The future of retail exemplifies this interconnected complexity in the context of emerging technologies because introducing them – such as robotics, artificial intelligence, and mixed reality – into retail environments requires a holistic consideration of the entire system, encompassing physical spaces, service processes, and human interactions.

This study examines a 15-week collaborative studio project between industrial design and architecture. By leveraging a systems thinking approach, the project facilitated cross-disciplinary collaboration to develop future retail concepts, enabling students to integrate their expertise and address the interconnectedness of artifacts, environments, and human interactions. Both disciplines followed a structured design process encompassing research, system design, space and robot design, visualization, and validation, while collaboration was organized around four key steps: planning, learning, prototyping, and communication. The project also involved collaboration with a supermarket chain, providing opportunities for onsite observations, employee interviews, and discussions with industry professionals. Students developed futuristic concepts for retail operations and customer experiences by leveraging the integration of mobile service robots, adaptive spaces, and mixed reality. Industrial design students focused on designing a product-service system of supermarket robots based on their redefinition of customer shopping experience and employee workflow, proposing an automated grocery order fulfillment system. Architecture students designed adaptive retail spaces that seamlessly blur the boundaries between physical and digital worlds, exploring how the Metaverse and mixed-reality interfaces can augment retail spaces and shopping experiences through dynamic, immersive interactions with digital avatars and robots. This cross-disciplinary collaboration resulted in holistic and integrative solutions for complex systems, presented through immersive VR experiences or animated scenarios.

This study’s contribution to design education is threefold. First, it proposes a systems thinking approach with cross-disciplinary collaboration for designing future retail experiences, demonstrating its effectiveness in addressing and designing complex socio-technical systems. Second, it offers insights into how industrial design and architecture can be integrated to create novel user experiences in digital transformation. Lastly, by examining the design and collaboration processes and reflecting on the opportunities and challenges, this study offers insights for its application to future studio courses. Given the increased complexity and dynamics between disciplines, thorough pre-planning and flexibility are critical for success.
