用机器人代替传统日记，实现自然场景下的人机交互数据收集。
Exploring the Use of Robots for Diary Studies
- 让机器人充当互动日记，主动询问用户日常体验。
- 一周家庭部署验证：机器人能有效获取与文本/音频日记相当的信息。
- 适合长期、隐私性强或需主动引导的在野研究场景。
随着对真实世界人机交互研究兴趣的增长，亟需在自然环境甚至私人空间中长期收集数据的方法。目前，人机交互（HRI）研究者常采用日记法，要求参与者在一段时间内自主填写结构化日记。尽管日记法能提供研究者难以进入的场景洞察，但缺乏访谈中的互动与深入追问。本文探索一种新方法：由机器人扮演互动日记角色。我们开发了Diary Robot系统，并进行了为期一周的家庭部署实验，评估该方法的可行性与有效性。以传统的文本和音频日记为基准，结果表明机器人能有效获取预期信息。我们反思研究发现，指出在需要持续互动、隐私敏感或需主动引导的情境下，使用机器人作为数据采集工具具有独特适用性。
原文摘要 · Abstract (English)
As interest in studying in-the-wild human-robot interaction grows, there is a need for methods to collect data over time and in naturalistic or potentially private environments. HRI researchers have increasingly used the diary method for these studies, asking study participants to self-administer a structured data collection instrument, i.e., a diary, over a period of time. Although the diary method offers a unique window into settings that researchers may not have access to, they also lack the interactivity and probing that interview-based methods offer. In this paper, we explore a novel data collection method in which a robot plays the role of an interactive diary. We developed the Diary Robot system and performed in-home deployments for a week to evaluate the feasibility and effectiveness of this approach. Using traditional text-based and audio-based diaries as benchmarks, we found that robots are able to effectively elicit the intended information. We reflect on our findings, and describe scenarios where the utilization of robots in diary studies as a data collection instrument may be especially applicable.
