Role-Aware Virtual Agents for Navigational Interaction guided by a Multimodal Large Language Model

摘要

We present a role-aware virtual agent navigational interaction that generates consistent, role-aligned movement behaviors. Our approach leverages Multimodal Large Language Models (MLLMs) to interpret multimodal inputs including scene information, user state, and high-level language role instruction, producing discrete navigation decisions and stylized planning path. Our approach enables virtual agents to behave consistently with narrative roles and respond to dynamic actions, such as playing a hide-and-seek taking into account the agent's role and the user's possible intention. Our approach demonstrates how MLLMs can go beyond language-based interaction to support embodied, spatial, and role-aware agent behaviors in immersive environments such as augmented reality.
