Hi. My name is Jaeyeon [JAY-awn] and I am an Assistant Professor in the department of Computer Science and Engineering at UNIST. The focus of my research is to comprehensively characterize user interfaces and interactions, to gain a thorough understanding of the critical elements of these interfaces and their relative strengths and weaknesses. Through quantitative and qualitative user studies, I aim to gain insight into the user experience associated with these novel interfaces and identify areas that require improvement to optimize their performance.
Previously, I completed my Ph.D. in Computer Science at KAIST in 2020, advised by Prof. Geehyuk Lee. I was also a research intern at Microsoft Research (with Mike Sinclair, Mar Gonzalez-Franco, Eyal Ofek, and Christian Holz) and Saarland University (with Prof. Jürgen Steimle). You can find the full list of my publications in my google scholar profile and in my CV (PDF).

Previous Research Projects

PseudoBend (UIST'19)
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.

TORC (@ Microsoft Research, CHI'19)
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.

Like a Second Skin (@ Saarland HCI Lab, Honorable Mention at CHI'19)
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.

Mode Errors in Korean-English Dual-language Keyboard (CHI'19)
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.

Square Watch Interaction (IJHCS, 2018)
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.

Touch Branch (Lumi Land (2017); Outstanding Paper Award at ISSM'17; DIS'18)
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.

Multimodal Watch-back Tactile Display (CHI'18)
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.

Non-contact Wearable Tactile Display (UIST'16)
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.

Watch-back Tactile Display (CHI'15)
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.
