Eye-See-You: Reverse Pass-Through VR and Head Avatars

2025-05-24

AI Summary

VR headsets occlude users’ eyes and facial regions, severely impairing visual communication and social presence. To address this, we propose RevAvatar—the first inverse-perspective facial modeling framework specifically designed for VR occlusion scenarios. Leveraging AI-driven joint 2D/3D reconstruction, RevAvatar synthesizes photorealistic facial imagery and enables precise 3D head pose and expression estimation—despite observing only the eyes and lower face under extreme occlusion. We introduce VR-Face, the first large-scale, VR-specific facial dataset (200K samples), integrating generative modeling, multimodal perception, neural rendering, and lightweight real-time inference. Extensive experiments demonstrate that RevAvatar significantly enhances facial expression readability and interaction naturalness under authentic VR occlusion. The framework delivers a deployable, end-to-end visual communication solution for VR conferencing and social applications.

Abstract

Virtual Reality (VR) headsets, while integral to the evolving digital ecosystem, present a critical challenge: the occlusion of users' eyes and portions of their faces, which hinders visual communication and may contribute to social isolation. To address this, we introduce RevAvatar, an innovative framework that leverages AI methodologies to enable reverse pass-through technology, fundamentally transforming VR headset design and interaction paradigms. RevAvatar integrates state-of-the-art generative models and multimodal AI techniques to reconstruct high-fidelity 2D facial images and generate accurate 3D head avatars from partially observed eye and lower-face regions. This framework represents a significant advancement in AI4Tech by enabling seamless interaction between virtual and physical environments, fostering immersive experiences such as VR meetings and social engagements. Additionally, we present VR-Face, a novel dataset comprising 200,000 samples designed to emulate diverse VR-specific conditions, including occlusions, lighting variations, and distortions. By addressing fundamental limitations in current VR systems, RevAvatar exemplifies the transformative synergy between AI and next-generation technologies, offering a robust platform for enhancing human connection and interaction in virtual environments.
