A survey of visual-language foundation models for enhancing virtual and augmented reality interactivity
摘要
Visual-language foundation models (VLFMs) are rapidly emerging as key enablers of interaction in virtual and augmented reality (VR/AR). By integrating advanced visual perception with language-based reasoning, they overcome the limitations of rule-driven systems and enable more natural, adaptive, and context-aware engagement. This paper provides a systematic survey of the evolving roles of VLFMs in immersive environments. We introduce the Interaction-Role Taxonomy, a novel framework that categorizes VLFMs into three complementary functions: the Semantic Interpreter, which perceives and interprets environments; the Embodied Agent, which facilitates collaborative interaction; and the Generative Engine, which creates dynamic content. Building on this framework, we review representative applications, analyze implementation pipelines and evaluation protocols, and critically discuss technical and ethical challenges. Finally, we identify open research directions to enhance the capability, efficiency, and trustworthiness of VLFMs, paving the way for next-generation human–computer interaction in immersive VR/AR ecosystems.
