Mikasa：受日本Oshi文化启发的以角色驱动的情感AI伴侣
Mikasa: A Character-Driven Emotional AI Companion Inspired by Japanese Oshi Culture
AI总结：
Mikasa通过稳定角色和明确关系定义，展示角色驱动设计在情感AI伴侣中的功能性。
摘要：
近年来，大语言模型和多模态交互的进展使得开发能够进行流畅且情感丰富的对话的AI伴侣成为可能。然而，许多这些系统在保持用户长期满意度和参与度方面存在问题。本文认为，这些问题并非主要源于模型薄弱，而是源于角色设计不佳和用户-人工智能关系定义不清晰。我介绍了Mikasa，一个受日本Oshi文化启发的情感AI伴侣——特别是其对长期、非排他性承诺稳定角色的强调，作为角色驱动伴侣设计的案例研究。Mikasa不作为通用助手或可切换角色的聊天机器人工作。相反，Mikasa被设计为具有稳定个性和明确关系定义的连贯角色。这种关系不强制排他性或义务。而是作为一种参考点，稳定交互规范，减少用户保持重新定义关系的工作量。通过探索性评估，我发现用户使用表面质量如对话自然性来描述他们的偏好，但他们在关系控制和想象参与方面也以未直接陈述的方式重视这些。这些结果表明，角色连贯性和关系定义在交互感觉好方面起着潜在的结构性作用，而用户并未将其视为主要特征。这项工作的贡献是展示角色设计是AI伴侣系统功能的一部分，而不仅仅是装饰。Mikasa是基于特定文化背景的一个例子，但设计原则——对一致个性的承诺和明确的关系定义——可以用于许多情感基础的AI伴侣。
英文摘要：
Recent progress in large language models and multimodal interaction has made it possible to develop AI companions that can have fluent and emotionally expressive conversations. However, many of these systems have problems keeping users satisfied and engaged over long periods. This paper argues that these problems do not come mainly from weak models, but from poor character design and unclear definitions of the user-AI relationship. I present Mikasa, an emotional AI companion inspired by Japanese Oshi culture-specifically its emphasis on long-term, non-exclusive commitment to a stable character-as a case study of character-driven companion design. Mikasa does not work as a general-purpose assistant or a chatbot that changes roles. Instead, Mikasa is designed as a coherent character with a stable personality and a clearly defined relationship as a partner. This relationship does not force exclusivity or obligation. Rather, it works as a reference point that stabilizes interaction norms and reduces the work users must do to keep redefining the relationship. Through an exploratory evaluation, I see that users describe their preferences using surface-level qualities such as conversational naturalness, but they also value relationship control and imaginative engagement in ways they do not state directly. These results suggest that character coherence and relationship definition work as latent structural elements that shape how good the interaction feels, without users recognizing them as main features. The contribution of this work is to show that character design is a functional part of AI companion systems, not just decoration. Mikasa is one example based on a specific cultural context, but the design principles-commitment to a consistent personality and clear relationship definition-can be used for many emotionally grounded AI companions.
