实测老年社区机器人咖啡师，发现用户留存低且问题重重
Faulty Coffees: Barriers to Adoption of an In-the-wild Robo-Barista
- 用叙事对话与非叙事对话对比，测试长期互动吸引力
- 五周实验中重复使用率低，仅少数人持续互动
- 揭示真实场景下机器人部署的障碍，适合做人机交互研究参考
我们旨在研究基于任务的叙述是否能影响用户对服务机器人的长期参与。为此，我们在英格兰斯托克顿的一个50岁以上居民小区内部署了一台机器人咖啡师，为期五周。居民通过与分配至叙事或非叙事对话条件的Furhat机器人互动，可免费获得每日一杯咖啡。尽管设计目标是促进持续参与，但实际中重复互动率极低，出现了大量好奇性尝试却无持续行为的情况，伴随技术故障、可及性障碍以及住宅区特有的社交动态问题。本文不将这些视为次要问题，而是将其置于核心位置，反思实验在真实环境中的困境，为未来长期人机交互研究提供实践教训。
原文摘要 · Abstract (English)
We set out to study whether task-based narratives could influence long-term engagement with a service robot. To do so, we deployed a Robo-Barista for five weeks in an over-50's housing complex in Stockton, England. Residents received a free daily coffee by interacting with a Furhat robot assigned to either a narrative or non-narrative dialogue condition. Despite designing for sustained engagement, repeat interaction was low, and we encountered curiosity trials without retention, technical breakdowns, accessibility barriers, and the social dynamics of a housing complex setting. Rather than treating these as peripheral issues, we foreground them in this paper. We reflect on the in-the-wild realities of our experiment and offer lessons for conducting longitudinal Human-Robot Interaction research when studies unravel in practice.
