探索元宇宙视频的搜索需求，发现时间序列数据关键作用
Information Need in Metaverse Recordings -- A Field Study
- 通过专家访谈分析用户在元宇宙视频中的信息需求
- 确认图形渲染与输入设备的时间序列数据对检索至关重要
- 为元宇宙视频检索系统设计提供用例和用户画像
元宇宙记录（MVRs）是多媒体信息检索（MMIR）领域中一种新兴且未充分研究的媒体类型。本文通过实地研究，探讨了用户在MVR检索中的信息需求与搜索行为。通过对专家访谈的分析，识别出MVR的应用场景，并揭示了从图形渲染过程及关联输入输出设备捕获时间序列数据的重要性，这些数据与用户需求高度相关。研究还定义了使用案例、用户类型及针对MVR检索系统的具体要求，为构建面向MVR的检索系统提供了基础。研究成果有助于理解元宇宙视频检索中的信息搜索行为，推动该领域的未来研究与系统设计。
原文摘要 · Abstract (English)
Metaverse Recordings (MVRs) represent an emerging and underexplored media type within the field of Multimedia Information Retrieval (MMIR). This paper presents findings from a field study aimed at understanding the users information needs and search behaviors specific to MVR retrieval. By conducting and analyzing expert interviews, the study identifies application scenarios and highlights challenges in retrieving multimedia content from the metaverse. The results reveal existing application scenarios of MVRs and confirm the relevance of capturing time-series data from the graphical rendering process and related input-output devices, which are also highly relevant to user needs. Furthermore, the study provides a foundation for developing retrieval systems tailored to MVRs by defining use cases, user stereotypes, and specific requirements for MVR Retrieval systems. The findings contribute to a better understanding of information search behaviors in MVR Retrieval and pave the way for future research and system design in this field.
