本研究通过参与式设计构建了基于关系的语音记忆伴侣MeBo，评估显示其可用性高，能增强老年人积极情感与社交联系，并引发关于记忆所有权与存续的伦理思考。
AI 中文摘要
自传体记忆有助于维持晚年生活中的身份认同、幸福感和社交联系，然而现有的基于语音的记忆技术大多依赖于孤立的提示。我们通过参与式设计，与11位老年人共同设计并构建了MeBo，一个功能完备的、基于关系的语音记忆伴侣。他们的叙述塑造了四项设计策略，这些策略指导了MeBo的交互设计和多智能体实现。在一项涉及20位老年人的混合方法评估中，参与者发现MeBo异常易用（SUS=87.75）、令人愉快、善于社交、情感响应及时且值得信赖。与使用前相比，参与者在会话后报告了更高的积极情感和即时的社交联系，以及更低的消极情感。参与者描述了MeBo如何跟随他们的故事、回到较早的记忆、适应他们的偏好，并使其不断增长的记忆可见且可控。MeBo的关系性框架引发了关于它应该记住什么、谁可以访问通过交互产生的记忆，以及当用户或MeBo不再存在时这些记忆会变成什么的紧张问题。
英文摘要
Autobiographical remembering supports identity, well-being, and social connection in later life, yet voice-based memory technologies largely rely on isolated prompts. We designed and built MeBo, a fully functional relational voice-based memory companion, through participatory design with 11 older adults. Their accounts shaped four Design Strategies that guided MeBo's interaction design and multi-agent implementation. In a mixed-methods evaluation with 20 older adults, participants found MeBo exceptionally usable (SUS = 87.75), enjoyable, sociable, emotionally responsive, and trustworthy. Participants reported higher positive affect and momentary social connection and lower negative affect after the session than before. Participants described how MeBo followed their stories, returned to earlier memories, adapted to their preferences, and made its growing memory visible and controllable. MeBo's relational framing surfaces tensions around what it should remember, who may access memories produced through interaction, and what becomes of them when the user or MeBo is no longer present.
