About Me
Hello, I’m Dong-Geun Kim, a Ph.D. student at POSTECH. My research interests include mid-air haptic rendering, haptic perception, and tactile language communication.
I also enjoy playing baseball in my free time!
Funded Projects
Developed multimodal haptic feedback tools to enhance user experience in AR-based sports applications. I was responsible for designing devices that render realistic haptic sensations by combining vibration, shear force, and impact feedback.
Designed performance metrics to assess and enhance user experience in interactive digital environments. I conducted research on haptic generation to improve user experience through cross-modal matching of sound and touch.
Mid-air Haptic Rendering for Digital Twin (PM)
Institute for Information & communications Technology Planning & Evaluation (IITP)
Jan. 2023 – Dec. 2024
Leading the development of real-time mid-air haptic rendering technologies integrated with digital twin systems. I conducted research on enhancing the perceived intensity of weak mid-air tactile stimuli using cognitive modulation techniques within a digital twin framework.
Investigating the Luxuriousness of Haptic Warning on the Steering Wheel
Hyundai Motors
Apr. 2023 - Apr. 2024
Explored how users perceive the luxuriousness of haptic warning feedback on a car steering wheel. Focused on designing haptic alerts that not only convey urgency but also deliver a refined and premium tactile experience.
Tactile Korean System for the Visually and Hearing Impaired (PM)
Institute for Information & communications Technology Planning & Evaluation (IITP)
Jan. 2025 – Present
Conducting research on tactile delivery of korean language using vibrotactile arrays to support communication for people with sensory disabilities.
Experience
POSTECH Kim Lab
Research Assistant
Sep. 2019 – May 2020
Developed high-frequency ultrasound transducers for tactile applications. Focused on hardware prototyping, acoustic modeling, and signal control to enable precise ultrasonic stimulation.
Education
Ulsan National Institute of Science and Technology (UNIST)
B.S. in Mechanical Engineering
2014 – 2019
UNIST is one of Korea’s top science and technology universities, offering an interdisciplinary curriculum that combines fundamental engineering with innovation-driven research.
I studied mechanical engineering at UNIST, building a strong foundation in physical systems and dynamics. Based on the knowledge and problem-solving mindset I acquired there, I progressed into the IT Convergence program at POSTECH, where I now integrate mechanical and computational knowledge to conduct advanced haptic research.
Pohang University of Science and Technology (POSTECH)
Integrated M.S./Ph.D. in IT Convergence Engineering
2020 – Present
POSTECH is a world-class research-oriented university consistently ranked among the top in Asia, renowned for its cutting-edge research environment and strong emphasis on interdisciplinary innovation.
I am currently pursuing an integrated M.S./Ph.D. program in IT Convergence Engineering at POSTECH. By leveraging both mechanical and computational knowledge, I am actively conducting interdisciplinary research in the field of haptics, focusing on tactile perception, mid-air stimulation, and language-based tactile communication. This environment allows me to collaborate with experts across domains and develop impactful solutions in next-generation interaction technologies.
