About

I am a graduate student at Interaction laboratory, POSTECH, South Korea. I am interested in VR/AR/Metaverse, haptics, and human‑computer interaction (HCI). My research goal is to present immersive experiences to users by studying the perception of the user’s various senses and designing haptic rendering algorithms based on it.

Specifically, my research focuses on:

  • Multimodal Interaction in Metaverse
  • Automatic Synthesis and Rendering of Haptic Motion Effects
  • Multimodal and Crossmodal Perception of Visual, Vestibular, and Haptic Senses
  • Human-Computer Interaction
