The question
Can granular synthesis create convincing tactile feedback from short signal fragments?
The approach
This project began with a question about simplicity: could perceptually meaningful cues support convincing virtual touch without reproducing every physical detail?
I used granular synthesis to assemble short signal fragments into vibrotactile feedback coupled to a person’s movement, and built an interactive VR environment to study the resulting experience.
Behavioral evaluation
I designed and conducted two-alternative forced-choice (2AFC) experiments, in which participants compared pairs of feedback conditions, alongside VR interaction studies. The effects on haptic experience depended on the task, motivating closer attention to how an interaction shapes what people perceive.
My contribution
Led hardware and VR implementation, user-study design and execution, data analysis, and manuscript writing at KAIST WIT Lab.
I worked as a research intern from January to September 2026, advised by Prof. Ian Oakley and collaborating with Prof. Sangho Yoon at KAIST’s HCI Tech Lab.
A connected question
Differences in how people experienced feedback prompted questions about the processes that turn a sensory cue into an interpretation.
