The Influence of Emotion-based Prioritized Facial Expressions on Social Presence in Avatar-mediated Remote Communication
Published in 2024 IEEE International Symposium on Mixed and Augmented Reality (ISMAR), 2024
We examine how prioritizing emotion-related facial expressions in avatar animation affects perceived social presence in avatar-mediated remote communication.

How Collaboration Context and Personality Traits Shape the Social Norms of Human-to-Avatar Identity Representation
Published in IEEE Transactions on Visualization and Computer Graphics (TVCG), 2025
We surveyed 150 participants to investigate social norms surrounding avatar modifications, examining how perspectives, contexts, and personality traits influence attitudes toward appropriateness.

Effects of AI-Powered Embodied Avatars on Communication Quality and Social Connection in Asynchronous Virtual Meetings
Published in IEEE Transactions on Visualization and Computer Graphics (TVCG), 2025
In this paper, we introduce AVAGENTs, AI-powered virtual avatars that replicate users’ verbal and nonverbal cues from recordings of past meetings. AVAGENTs interpret meeting context and generate appropriate responses to questions posed by asynchronous viewers.

Streamlined Facial Data Collection based on Utterance and Emotional Data for Human-to-Avatar Reconstruction
Published in IEEE Transactions on Visualization and Computer Graphics (TVCG), 2026
We systematically investigate which facial expression data are essential for reconstructing photorealistic avatars and how they can be captured efficiently.
OFERA: Blendshape-driven 3D Gaussian Control for Occluded Facial Expression to Realistic Avatars in VR
Published in IEEE Transactions on Visualization and Computer Graphics (TVCG), 2026
We propose OFERA, a novel framework for real-time expression control of photorealistic Gaussian head avatars for VR headset users.
