Hi. My name is Jaeyeon [JAY-awn] and I am a Ph.D. candidate in the School of Computing, KAIST.
As a Human-Computer Interaction (HCI) researcher, I have been exploring human haptic perception on various types of computers, including wearable, hand-held, and on-skin interfaces. In my research, I create novel physical user interfaces that enable efficient and natural interactions based on the findings from empirical experiments on human perception to enrich the intersection of HCI and Haptics.
Last summer, I did a research internship at Microsoft Research with Mike Sinclair, Mar Gonzalez-Franco, Eyal Ofek, Christian Holz, and Ken Hinckley. Our paper on a VR controller for in-hand interaction was presented at CHI 2019. Before the internship, I was a visiting student at the HCI Lab (aka the 'iSkin Lab') at Saarland University led by proferssor Jürgen Steimle. Our paper on the human tactile perception with on-skin overlays also was presented at CHI 2019 and received Honorable Mention Award.
I am a recipient of NAVER Ph.D. Fellowship. I have M.S. in Electrical Engineering from KAIST and B.Eng. in Control Engineering from Kwangwoon University. Full list of publications is shown in the Project and Publication sections.

We present a technique for haptic feedback that creates the illusion that a rigid device is being stretched, bent, or twisted. The method uses a single 6-DOF force sensor and a vibrotactile actuator to render grain vibrations to simulate the vibrations produced during object deformation based on the changes in force or torque exerted on a device.
Recent hand-held controllers have explored a variety of haptic feedback sensations for users in virtual reality by producing both kinesthetic and cutaneous feedback from virtual objects. These controllers are grounded to the user's hand and can only manipulate objects through arm and wrist motions, not using the dexterity of their fingers as they would in real life.
The emerging class of epidermal devices opens up new opportunities for skin-based sensing, computing, and interaction. Future design of these devices requires an understanding of how skin-worn devices affect the natural tactile perception.
In countries where languages with non-Latin characters are prevalent, people use a keyboard with two language modes namely, the native language and English, and often experience mode errors. To diagnose the mode error problem, we conducted a field study and observed that 78% of the mode errors occurred immediately after application switching.
Smartwatch has a limited input vocabulary because of its small touchscreen. Using touch sensitive edge as an input is one of the promising solutions. We explored interaction techniques that use the possible combinations of touch sensitive edges and the touchscreen.
Interpersonal touch, one of the most primitive social languages, is an excellent design element frequently utilized in interaction design. We built an interactive system that can sense simple touch and interpersonal touches. We observed the interpersonal touches and discussed the effect of social relationship and the spatial distance. This research project was a part of an interactive installation project,Lumi Land (2017), at National Science Museum in Korea.
We proposed the idea of layering two disjoint tactile sensations (wind and vibration) together to expand the information capacity of watch-back tactile display. We presented interaction scenarios and the pattern recognition experiment results of multimodal tactile display.
Traditional wearable tactile displays transfer tactile stimulations through a firm contact between the stimulator and the skin. We conjecture that a firm contact may not be always possible and acceptable. We explored the concept of a non-contact wearable tactile display using an airflow, which can transfer information without a firm contact.
A watch-back tactile display (WBTD) is expected to be a viable supplement to the user interface limitations of a smartwatch. However, its design requires that many design parameters such as tactor types and stimulus patterns be determined. We conducted a series of experiments to explore a best design of a WBTD consisting of 3×3 tactors and presented the results.
