赛博格安卓化身“Yui”：系统集成、现场部署与评估
Cybernetic Android Avatar "Yui": System Integration, Field Deployment, and Evaluation
AI总结：
提出全身赛博格安卓化身Yui，集成操作者沉浸式遥操作与对话者类人社交信号，通过世博会长期展览、远程教育交流等实际部署验证可行性，获得共在感和情绪传达的积极评价。
摘要：
远程通信技术已广泛使用，但在许多社交互动场景中，支持共享物理空间感和传达丰富的非语言线索仍然具有挑战性。本研究介绍了“Yui”，一种全身赛博格安卓化身，旨在将操作者沉浸式遥操作与对话者类人社交信号相结合。Yui 结合了55自由度的全身机构与先前开发的安卓头部、面部表情和注视控制、上半身和手臂运动、手部驱动以及移动平台。它可以通过基于头戴显示器的沉浸式模式或基于网络摄像头的桌面模式进行操作。我们通过三个实际部署评估了系统：日本关西大阪2025年世博会的长期公共展览、小学生之间的远程教育交流以及与普通参与者的公共互动研究。在世博会部署期间，两个单元累计运行约1131小时，展示了操作可行性和维护挑战。在公共研究中，操作者和对话者均报告了对共在感的积极印象和使用意愿。对话者还在类人性和情绪及意图传达方面对化身给予了积极评价。结果表明对普通操作者具有可用性，同时在精确可控性方面存在改进空间。这些发现为可社交部署的全身安卓化身提供了现场证据和设计启示。
英文摘要：
Remote communication technologies have become widely used; however, supporting a sense of shared physical space and conveying rich non-verbal cues remain challenging in many social interaction scenarios. This study presents "Yui," a full-body cybernetic android avatar designed to integrate operator-side immersive teleoperation with interlocutor-side human-like social signaling. Yui combines a 55-degrees of freedom full-body mechanism with a previously developed android head, facial expression and gaze control, upper-body and arm motion, hand actuation, and a mobile platform. It can be operated through either the immersive mode using a head mounted display-based interface or desktop mode using a webcam-based interface. We evaluated the system through three real-world deployments: a long-term public exhibition at Expo 2025 in Osaka, Kansai, Japan; a remote educational exchange between elementary school students; and a public interaction study with general participants. During the Expo deployment, two units accumulated approximately 1131 h of operation, demonstrating both operational feasibility and maintenance challenges. In the public study, both operators and interlocutors reported positive impressions of co-presence and willingness to use the system. Interlocutors also rated the avatar positively in terms of human likeness and the transmission of emotions and intentions. The results indicate usability for general operators while suggesting room for improvement in precise controllability. These findings provide field-derived evidence and design implications for socially deployable full-body android avatars.
