HiSync: Spatio-Temporally Aligning Hand Motion from Wearable IMU and On-Robot Camera for Command Source Identification in Long-Range HRI

Long-range Human-Robot Interaction (HRI) remains underexplored. Within it, Command Source Identification (CSI) – determining who issued a command – is especially challenging due to multi-user and distance-induced sensor ambiguity. We introduce HiSync, an optical-inertial fusion framework that treats hand motion as bin…

InterQuest: A Mixed-Initiative Framework for Dynamic User Interest Modeling in Conversational Search

In online information-seeking tasks (e.g., for products and restaurants), users seek information that aligns with their individual preferences to make informed decisions. However, existing systems often struggle to infer users' implicit interests—unstated yet essential preference factors that directly impact decision…

From Operation to Cognition: Automatic Modeling Cognitive Dependencies from User Demonstrations for GUI Task Automation

Traditional Programming by Demonstration (PBD) systems primarily automate tasks by recording and replaying operations on Graphical User Interfaces (GUIs), without fully considering the cognitive processes behind operations. This limits their ability to generalize tasks with interdependent operations to new contexts (e…

Investigating Context-Aware Collaborative Text Entry on Smartphones using Large Language Models

Text entry is a fundamental and ubiquitous task, but users often face challenges such as situational impairments or difficulties in sentence formulation. Motivated by this, we explore the potential of large language models (LLMs) to assist with text entry in real-world contexts. We propose a collaborative smartphone-b…
