Sensorimotor Stickies: A Reconfigurable On-Body Platform for Closed-Loop Sensorimotor Training
Tianhong Catherine Yu, Jiwei Zheng, Chi-Jung Lee +5
Closed-loop sensorimotor training systems can improve learning by sensing movement and delivering real-time feedback, yet most are built as fixed implementations tied to a single t…
WatchHand: Enabling Continuous Hand Pose Tracking On Off-the-Shelf Smartwatches
Jiwan Kim, Chi-Jung Lee, Hohurn Jung +4
Tracking hand poses on wrist-wearables enables rich, expressive interactions, yet remains unavailable on commercial smartwatches, as prior implementations rely on external sensors…
Grab-n-Go: On-the-Go Microgesture Recognition with Objects in Hand
Chi-Jung Lee, Jiaxin Li, Tianhong Catherine Yu +4
As computing devices become increasingly integrated into daily life, there is a growing need for intuitive, always-available interaction methods, even when users' hands are occupie…
EchoForce: Continuous Grip Force Estimation from Skin Deformation Using Active Acoustic Sensing on a Wristband
Kian Mahmoodi, Yudong Xie, Tan Gemicioglu +3
Grip force is commonly used as an overall health indicator in older adults and is valuable for tracking progress in physical training and rehabilitation. Existing methods for weara…
WristSonic: Enabling Fine-grained Hand-Face Interactions on Smartwatches Using Active Acoustic Sensing
Saif Mahmud, Kian Mahmoodi, Chi-Jung Lee +2
Hand-face interactions play a key role in many everyday tasks, providing insights into user habits, behaviors, intentions, and expressions. However, existing wearable sensing syste…
SeamPose: Repurposing Seams as Capacitive Sensors in a Shirt for Upper-Body Pose Tracking
Tianhong Catherine Yu, Manru Mary Zhang, Peter He +6
Seams are areas of overlapping fabric formed by stitching two or more pieces of fabric together in the cut-and-sew apparel manufacturing process. In SeamPose, we repurposed seams a…
Ring-a-Pose: A Ring for Continuous Hand Pose Tracking
Tianhong Catherine Yu, Guilin Hu, Ruidong Zhang +9
We present Ring-a-Pose, a single untethered ring that tracks continuous 3D hand poses. Located in the center of the hand, the ring emits an inaudible acoustic signal that each hand…
EchoWrist: Continuous Hand Pose Tracking and Hand-Object Interaction Recognition Using Low-Power Active Acoustic Sensing On a Wristband
Chi-Jung Lee, Ruidong Zhang, Devansh Agarwal +10
Our hands serve as a fundamental means of interaction with the world around us. Therefore, understanding hand poses and interaction context is critical for human-computer interacti…
