Dong-Geun Kim 김동근

Ph.D. Candidate, POSTECH Interaction Lab

I am a Ph.D. candidate in the Interaction Lab at POSTECH. My research is on vibrotactile perception and tactile communication: how well people can identify and localize vibration patterns on the forearm, and how those patterns can be used to carry information. Right now I am building a tactile Korean system for people with visual or hearing impairments. I have also worked on mid-air ultrasonic haptics and on matching sounds to touch.

Research

Tactile communication. Delivering text and other information through vibration patterns on the forearm, so it can be read by touch.
Vibrotactile perception. Measuring how the number, placement, and timing of tactors change what people can identify and where they feel it.
Mid-air haptics. Making weak ultrasonic mid-air stimuli feel stronger and easier to recognize by adding vibration at the wrist.
