abstract = {This work analyzes the deployment of conversational agents based on large language models (LLMs) in cloud-edge architectures, placing emphasis on scalability, efficiency and real-time performance. Through a case study, we present a web application that allows users to interact with an augmented reality avatar that impersonates a historical character. The agent, powered by an LLM delivers immersive and contextually coherent dialogues. We discuss the solutions adopted to manage latency and distribute the computational load between the cloud, which takes care of language processing, and the edge nodes, ensuring a smooth user experience. The results obtained demonstrate how accurate design can optimize the use of LLMs in distributed environments, offering advanced and high-performance interactions even in applications with high reactivity and customization requirements. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.},

abstract = {In our project, we aimed to create historically authentic and vivid virtual representations of historic personalities that are connected to the regional Fichtelgebirge (Bavaria, Germany) to support the storytelling of our immersive XR applications. We are describing the tools in detail, the process of the tool chain and the resulting media. Next, we are discussing the challenges in media production like historical correctness and the consultation of historians. In order to create visual reproducibility we are explaining the detailed text prompts, their limitations and how to cope with resulting errors of the human physiognomy. Finally, we are briefly describing the application of the animated and talking generated historic characters in an immersive interactive WebXR environment. The XR experience is presented in web browsers on smartphones, tablets and XR headsets and the underlying software is based on the open-source framework Aframe. Our paper will describe the process, the results and the limitations in detail. Furthermore, we will provide a flow chart of the tool pipeline with visual examples of these aspects. The animations and voices of the historic characters will be demonstrated in videos of the XR application. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.},
