让工业机器人主动聊天，能显著提升人机亲密度和互动意愿。
"See You Later, Alligator": Impacts of Robot Small Talk on Task, Rapport, and Interaction Dynamics in Human-Robot Collaboration
- 机器人在装配任务中主动发起闲聊，促进人际连接。
- 73%的参与者在任务末期仍与机器人持续对话，59%主动提问。
- 虽任务时间更长，但人机关系更融洽，适合需协作信任的场景。
闲聊可增强人与人之间的默契；然而，非拟人化机器人（如工业中常用的合作机械臂）如何利用此类社交交流尚不明确。本研究探讨了机器人主动发起闲聊对人机协作中任务表现、情感联结及交互动态的影响。我们开发了一个自主机器人系统，在协助人类完成装配任务时主动开展闲聊。通过一项用户研究（N = 58），参与者与仅进行任务导向对话的功能型机器人或同时发起闲聊的社交型机器人协作。结果显示，社交组参与者报告的与机器人亲密度显著更高。所有社交组参与者均回应了机器人的闲聊尝试：59%主动提问，73%在请求最终任务物品后继续对话。尽管实际工作时间相近，社交组任务总耗时更长。研究讨论了机器人闲聊设计对人机协作的意义。
原文摘要 · Abstract (English)
Small talk can foster rapport building in human-human teamwork; yet how non-anthropomorphic robots, such as collaborative manipulators commonly used in industry, may capitalize on these social communications remains unclear. This work investigates how robot-initiated small talk influences task performance, rapport, and interaction dynamics in human-robot collaboration. We developed an autonomous robot system that assists a human in an assembly task while initiating and engaging in small talk. A user study ($N = 58$) was conducted in which participants worked with either a functional robot, which engaged in only task-oriented speech, or a social robot, which also initiated small talk. Our study found that participants in the social condition reported significantly higher levels of rapport with the robot. Moreover, all participants in the social condition responded to the robot's small talk attempts; 59% initiated questions to the robot, and 73% engaged in lingering conversations after requesting the final task item. Although active working times were similar across conditions, participants in the social condition recorded longer task durations than those in the functional condition. We discuss the design and implications of robot small talk in shaping human-robot collaboration.
