Hi. My name is Jaeyeon Lee.

I am a phd candidate in the School of Computing, KAIST. I am a member of HCI Lab led by professor Geehyuk Lee.
In the field of Human-computer Interaction, my research focuses on the physical interfaces that user touches. Particularly, I am interested in the potential of wearable tactile interfaces that enable comfortable and efficient interactions.

Research Projects

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.

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 (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 interpersonal touches, and analyzed 408 touches. We discussed the effect of social relationship and the spatial distance.
This research project was a part of an interactive installation project, Lumi Land (2017), collaborated with National Science Museum and KAIST Wonder Lab.
