Function-Adaptive Affordance Extraction from 3D Objects Using LLM for Interaction Authoring with Augmented Artifacts

We propose an algorithm that extracts the most suitable affordances, interaction targets, and corresponding coordinates adaptively from 3D models of various artifacts based on their functional context for efficient authoring of XR content with artifacts. Traditionally, authoring AR scenes to convey artifact context required one-to-one manual work. Our approach leverages a Large Language Model (LLM) to extract interaction types, positions, and subjects based on the artifact's name and usage context. This enables templated XR experience creation, replacing repetitive manual labor. Consequently, our system streamlines the XR authoring process, making it more efficient and scalable.
