In 2021, we published several papers about 4D motion effects and haptic perception/rendering. For 4D motion effects, our research about “Improving Viewing Experiences of First-Person Shooter Gameplays with Automatically-Generated Motion Effects” was presented in the 2021 CHI and “Camera Space Synthesis of Motion Effects Emphasizing a Moving Object in 4D films” was presented in the 2021 IEEE VR. About haptic rendering, “Perceived Magnitude Function of Friction Rendered by the Dahl Model” and “Vibrotactile Metaphor of Physical Interaction Using Body-Penetrating Phantom Sensations: Stepping on a Virtual Object” were published in the 2021 IEEE WHC. Last but not least, “Length Perception Model for Handheld Controllers: The Effects of Diameter and Inertia” will be published in the IEEE ToH. For more information, please see our publications tab.
Chaeyong Park have won the Encouragement Award at the 1st Postech Excellence Competition. He received the award for his achievements in more than five papers and two or more patents. A plaque and a prize of 300,000 won were awarded at the department faculty meeting on the April 5th.
Our lab was introduced in Postech LabCumentary. Postech LabCumentary is a two-minute lab documentary so that anyone can easily understand the research in the laboratory. From the video, you can find out what we are studying and interested in. The news and the video could be checked through the link below.

Four new members entered the interaction lab in the spring semester of 2021. Jungeun Lee (left-top) entered the lab as a Ph.D student. Her master’s thesis was about the prediction model of electric muscle stimulation. Jeongwoo Kim (right-top) started his degree with an integrated master’s and Ph.D program. He studied vibrotactile feedback for weight perception in our lab as an undergraduate student. Jaejun Park (left-bottom) and Daehyun Nam (right-bottom) entered the lab with a master’s program. Jaejun Park studied thermal haptic feedback and electrovibration in our lab as an undergraduate student.
Today, Hyoseung Lee and Jiwan Lee were awarded master’s degrees. Hyoseung Lee presented a master’s thesis about motion effect synthesis based on human walking motion and is going to continue his career as a researcher in the industry. Jiwan Lee presented a master’s thesis about perception of motion effects in 4D experiences and is going to do further research as Ph.D in our lab. Praise for the bright future of our graduates!
Prof. Ki-Uk Kim and Seungmoon Choi co-translated an introductory English book about haptics originally written by Lynette Jones. This book is for readers without specific technological backgrounds and made available by Gimmyoung.
We have won a new research grant from the Support Program for the Reinforcement of Science Culture Exhibition Service funded the National Research Foundation of Korea. In this project, we will study the technologies, systems, and long-term user experiences for blending real and virtual exhibits in order to promote in-depth, embodied learning of scientific principles, in close collaboration with Prof. Keehoon Kim in mechanical engineering and his lab members. We will be supported 770 million won for 2.5 years.
We had a half-day lab outing to Jangsa Beach and Okgye Valley, taking adequate precautions against COVID-19. Though it was a rainy day, we had a very fun time together with delicious food. Thank you so much for Gihong and Chaeyong for organizing it!
We have renamed our laboratory from Haptics and Virtual Reality Laboratory to Interaction Laboratory, reflecting our expanded research areas over the past 15 years. A new homepage is also launched, which is what you are looking at.
Our research about “Augmenting Physical Buttons with Vibrotactile Feedback for Programmable Feels” will be presented in the 2020 UIST in October. This work presents a very simple yet effective method that enables us to diversify the haptic sensation of pressing a physical button by adding a simple vibration signal, as well as its perceptual evaluation results. Congratulations to the authors, Chaeyong Park, Jinhyuk Yoon, and Seungjae Oh!
