A Review of Behavioral Closed-Loop Paradigm from Sensing to Intervention for Ingestion Health
Jun Fang, Yanuo Zhou, Ka I Chan +8
Ingestive behavior plays a critical role in health, yet many existing interventions remain limited to static guidance or manual self-tracking. With the increasing integration of se…
Unknown Word Detection for English as a Second Language (ESL) Learners Using Gaze and Pre-trained Language Models
Jiexin Ding, Bowen Zhao, Yuntao Wang +4
English as a Second Language (ESL) learners often encounter unknown words that hinder their text comprehension. Automatically detecting these words as users read can enable computi…
Modeling the Impact of Visual Stimuli on Redirection Noticeability with Gaze Behavior in Virtual Reality
Zhipeng Li, Yishu Ji, Ruijia Chen +4
While users could embody virtual avatars that mirror their physical movements in Virtual Reality, these avatars' motions can be redirected to enable novel interactions. Excessive r…
SonarWatch: Field sensing technique for smartwatches based on ultrasound and motion
Yingtian Shi, Chun Yu, Xuyang Lu +3
A smartwatch worn continuously on the wrist has the potential to perceive rich interactive gestures and natural behaviors of the user. Unfortunately, the current interaction functi…
The Odyssey Journey: Top-Tier Medical Resource Seeking for Specialized Disorder in China
Ka I Chan, Siying Hu, Yuntao Wang +3
It is pivotal for patients to receive accurate health information, diagnoses, and timely treatments. However, in China, the significant imbalanced doctor-to-patient ratio intensifi…
G-VOILA: Gaze-Facilitated Information Querying in Daily Scenarios
Zeyu Wang, Yuanchun Shi, Yuntao Wang +6
Modern information querying systems are progressively incorporating multimodal inputs like vision and audio. However, the integration of gaze -- a modality deeply linked to user in…
Time2Stop: Adaptive and Explainable Human-AI Loop for Smartphone Overuse Intervention
Adiba Orzikulova, Han Xiao, Zhipeng Li +7
Despite a rich history of investigating smartphone overuse intervention techniques, AI-based just-in-time adaptive intervention (JITAI) methods for overuse reduction are lacking. W…
Leveraging Large Language Models for Generating Mobile Sensing Strategies in Human Behavior Modeling
Nan Gao, Zhuolei Yu, Yue Xu +4
Mobile sensing plays a crucial role in generating digital traces to understand human daily lives. However, studying behaviours like mood or sleep quality in smartphone users requir…
UbiPhysio: Support Daily Functioning, Fitness, and Rehabilitation with Action Understanding and Feedback in Natural Language
Chongyang Wang, Yuan Feng, Lingxiao Zhong +8
We introduce UbiPhysio, a milestone framework that delivers fine-grained action description and feedback in natural language to support people's daily functioning, fitness, and reh…
GazeReader: Detecting Unknown Word Using Webcam for English as a Second Language (ESL) Learners
Jiexin Ding, Bowen Zhao, Yuqi Huang +2
Automatic unknown word detection techniques can enable new applications for assisting English as a Second Language (ESL) learners, thus improving their reading experiences. However…
Enabling Voice-Accompanying Hand-to-Face Gesture Recognition with Cross-Device Sensing
Zisu Li, Cheng Liang, Yuntao Wang +5
Gestures performed accompanying the voice are essential for voice interaction to convey complementary semantics for interaction purposes such as wake-up state and input modality. I…
Modeling the Trade-off of Privacy Preservation and Activity Recognition on Low-Resolution Images
Yuntao Wang, Zirui Cheng, Xin Yi +7
A computer vision system using low-resolution image sensors can provide intelligent services (e.g., activity recognition) but preserve unnecessary visual privacy information from t…
Facilitating Self-monitored Physical Rehabilitation with Virtual Reality and Haptic feedback
Yu Jiang, Zhipeng Li, Ziyue Dang +8
Physical rehabilitation is essential to recovery from joint replacement operations. As a representation, total knee arthroplasty (TKA) requires patients to conduct intensive physic…
Modeling the Noticeability of User-Avatar Movement Inconsistency for Sense of Body Ownership Intervention
Zhipeng Li, Yu Jiang, Yihao Zhu +5
An avatar mirroring the user's movement is commonly adopted in Virtual Reality(VR). Maintaining the user-avatar movement consistency provides the user a sense of body ownership and…
FaceOri: Tracking Head Position and Orientation Using Ultrasonic Ranging on Earphones
Yuntao Wang, Jiexin Ding, Ishan Chatterjee +5
