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.

Ming Tang and Mikhail Nikolaenko presented “AI-Powered Digital Humans for Enhanced Interaction in Extended Reality” at the AI and Emerging Technology Symposium, University of Cincinnati.

The day-long event explored topics around AI and robotic process automation; smart campus innovation; and extended reality, virtual reality, and augmented reality. More on UC News.

AI-Powered Talking Avatars for Enhanced Interaction in Extended Reality

Presenter. Ming Tang, Mikhail Nikolaenko. Feb. 20, 2025 in Tangeman University Center. 

This presentation explores two AI-driven talking avatars developed at the UC Extended Reality (XR) Lab, leveraging large language models (LLMs) for realistic interaction in XR environments. The XRLab Bot acts as a virtual tour guide, providing real-time engagement and navigation through the lab with spatial awareness, while the P&G Bot emulates a high-fidelity human likeness, delivering product expertise within a VR setting. These bots highlight advancements in AI, LLMs, and XR, showcasing potential applications in education, customer service, and smart campuses. The presentation will cover AI-driven navigation, multi-client architecture, and XR integration for immersive digital experiences. The session will showcase AI-driven navigation and interaction, demonstrating the bot’s capabilities in translating speech-to-text using Whisper AI, retrieving responses from ChatGPT, and interpreting real-time visitor needs and spatial data to guide users throughout XRLab. It will explore the multi-client, real-time architecture by sharing insights on managing multiple Unreal and Python clients with a central server, coordinating bot actions, face tracking, and area-specific responses in real-time. The discussion will highlight XR integration and smart campus applications, emphasizing the bot’s adaptability within XR platforms using Unreal Engine and its potential for virtual and augmented reality applications in campus tours, orientations, and educational experiences. Additionally, the session will discuss LLM-driven conversational AI, utilizing advanced models to power sophisticated, natural language interactions with users. High-fidelity 3D avatar creation will be addressed, focusing on crafting detailed, lifelike avatars capable of mimicking human expressions and movements. It will also cover customizable AI for chat avatars, enabling personalized, AI-driven avatars tailored to specific user preferences and needs. Interactive avatars with facial animation and motion capture will be demonstrated, showing how avatars can exhibit dynamic facial expressions and reactions during interactions. The session will also explore metaverse creation, showcasing the development of immersive, interconnected virtual worlds where users can interact through their avatars. Finally, the discussion will include virtual reality (VR) and augmented reality (AR) environments and experiences, highlighting their ability to blend digital content with the physical world or create entirely virtual spaces.
