RingIO: An Eyes-Free Smart Ring with Inputs via Touch and Outputs via Touch

Proc. ACM UIST 2026
Lonnie Chien
Ph.D. Student in Computer Science at Cornell Tech
I am a first-year Ph.D. student in computer science at Cornell University advised by Thijs Roumen.
My current research in human-computer interaction (HCI) explores embodied interaction and haptic feedback for wearable devices—in particular, how multimodal output (e.g., proprioception, tactile) can improve input capabilities and accuracy.
I hold an M.S. in Computer Science from the University of Chicago, where I received pre-doctoral training from Pedro Lopes. I hold a B.S. in engineering and applied mathematics from Swarthmore College.
