LANGUAGE & TOUCH
Tactile communication
Encoding language and information into patterns that can be felt on the skin.
HAPTICS · HUMAN–COMPUTER INTERACTION
Making sense

I explore how we perceive touch—and how it can become a new channel for communication.
A different way to connect.Through the sense of touch.

01 / RESEARCH
Touch as information.
I am a Ph.D. candidate at POSTECH Interaction Lab. I study how touch can deliver information, shape perception, and create new ways to interact. My current work explores a tactile Korean system for people with sensory impairments.
HUMAN PERCEPTION
Vibrotactile perception
Understanding how the timing and location of vibration shape what we perceive.
HAPTIC INTERFACES
Mid-air haptics
Exploring contactless touch and how wrist vibration enhances ultrasonic sensations.
