Hi. My name is Jaeyeon [JAY-awn] and I am a phd candidate in the School of Computing, KAIST,
where I am advised by professor Geehyuk Lee.
As a Human-Computer Interaction (HCI) researcher, I have been exploring human haptic perception to body-worn computers including wearable, hand-held devices, and on-skin interfaces.
I have published papers on wearable haptic interfaces
(CHI'15, UIST'16, CHI'18),
smart watch interaction (IJHCS),
interpersonal touches in interactive installation (DIS'18).
Last summer, I did a research internship at Microsoft Research with Mike Sinclair. Our paper on a VR controller for in-hand interaction got accepted to CHI 2019.
Before the internship, I was a visiting student at the HCI Lab (aka the 'iSkin Lab') at Saarland University lead by proferssor Jürgen Steimle. Our paper on the human tactile perception with on-skin overlays also got accepted and recognized with Best Paper Honorable Mention Award.
Paper has been accepted to UIST 2017 Doctoral Symposium, one of my phd wishes :-)

TORC (@ Microsoft Research, accepted to CHI'19)
Recent hand-held controllers have explored a variety of haptic sensations for users. However, these controllers are grounded to the user's hand and can only manipulate objects through arm and wrist motion, not using the dexterity of their fingers as they would in real life.

Like a Second Skin (@ Saarland HCI Lab, accepted to 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 (accepted to 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); 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.
Keywords: Wind | Vibration | Information Transfer | Wearable 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.
