A modular augmented reality framework for real-time clinical data visualization and interaction

This paper presents a modular augmented reality (AR) framework designed to support healthcare professionals in the real-time visualization and interaction with clinical data. The system integrates biometric patient identification, large language models (LLMs) for multimodal clinical data structuring, and ontology-driven AR overlays for anatomy-aware spatial projection. Unlike conventional systems, the framework enables immersive, context-aware visualization that improves both the accessibility and interpretability of medical information. The architecture is fully modular and mobile-compatible, allowing independent refinement of its core components. Patient identification is performed through facial recognition, while clinical documents are processed by a vision-language pipeline that standardizes heterogeneous records into structured data. Body-tracking technology anchors these parameters to the corresponding anatomical regions, supporting intuitive and dynamic interaction during consultations. The framework has been validated through a diabetology case study and a usability assessment with five clinicians, achieving a System Usability Scale (SUS) score of 73.0, which indicates good usability. Experimental results confirm the accuracy of biometric identification (97.1%). The LLM-based pipeline achieved an exact match accuracy of 98.0% for diagnosis extraction and 86.0% for treatment extraction from unstructured clinical images, confirming its reliability in structuring heterogeneous medical content. The system is released as open source to encourage reproducibility and collaborative development. Overall, this work contributes a flexible, clinician-oriented AR platform that combines biometric recognition, multimodal data processing, and interactive visualization to advance next-generation digital healthcare applications.
