LLM-powered Devil’s Advocate
Exploring how LLM agents with AI-mediated Communications can stimulate critical thinking by representing minority perspectives in power-imbalanced group decision-making. (Focus: group dynamics, AI mediation, social influence, critical discourse) 
Vision-based Interactive System to Support Group Dance
Exploring the design space of a real-time vision-based feedback system using a single RGB camera to support synchronization in group dance practice. (Focus: embodied interaction, performance feedback, group coordination) 
Gesture-to-Emoji System in Online Meeting
Investigating how hand gestures can be automatically translated into emojis to enhance non-verbal communication in remote meetings. (Focus: expressive interaction, online collaboration, non-verbal cues) 
Counterfunctional Music Player (Critical Design)
An interactive music player object design that allows users to randomly play the songs that they often listen to in certain months through mid-air hand gesture input. [💻Code] [🎤Preview] [▶️Demo] 
InkStrings: Visualizing the Soul of Gayageum (Interactive Media Art)
InkStrings is an interactive installation that enables users to perform the traditional Korean instrument Gayageum through mid-air hand gestures using Leap Motion. As the user plays, the subtle vibratos (nonghyun) are translated into real-time visual expressions inspired by East Asian ink wash painting, dynamically capturing the nuances of sound through varying shades and textures of ink. [💻Code] [▶️Demo] 
Cognitive Workload for Hand Gesture Types in VR
Evaluating the cognitive and physical workload imposed by different gesture types in immersive VR environments. (Focus: usability, workload analysis, VR interface design) [📄Paper Preview] [🎨Poster] 
Nail Input Sensing
Developing touch-sensitive artificial nails to enable subtle and always-available hand input for mobile and wearable contexts. (Focus: novel input, wearable computing, subtle interaction)
