Shiye Cao, Jiwon Moon, Amama Mahmood, Victor Nikhil Antony, Ziang, Xiao, Anqi Liu, Chien-Ming Huang

TL;DR
This paper presents a real-time interruption handling system for conversational robots, improving interaction naturalness by detecting and managing user interruptions based on intent, validated through human-robot interaction experiments.
Contribution
The authors developed a system that detects and manages user-initiated interruptions in real-time, based on interaction patterns from human interactions, and integrated it into an LLM-powered social robot.
Findings
Successfully handled 93.69% of user interruptions
Validated system effectiveness through human-robot interaction tasks
Provided insights for designing interruption behaviors in robots
Abstract
Interruptions, a fundamental component of human communication, can enhance the dynamism and effectiveness of conversations, but only when effectively managed by all parties involved. Despite advancements in robotic systems, state-of-the-art systems still have limited capabilities in handling user-initiated interruptions in real-time. Prior research has primarily focused on post hoc analysis of interruptions. To address this gap, we present a system that detects user-initiated interruptions and manages them in real-time based on the interrupter's intent (i.e., cooperative agreement, cooperative assistance, cooperative clarification, or disruptive interruption). The system was designed based on interaction patterns identified from human-human interaction data. We integrated our system into an LLM-powered social robot and validated its effectiveness through a timed decision-making task and…
