Video has become a popular media form for information sharing and consumption. However, taking notes while watching a video requires significant time and effort. To address this, we propose a novel interactive system, NoTeeline, for taking real-time, personalized notes. NoTeeline lets users quickly jot down keypoints (micronotes), which are automatically expanded into full-fledged notes that capture the content of the user's micronotes and are consistent with the user's writing style. In a within-subjects study (N=12), we found that NoTeeline helps users create high-quality notes that capture the essence of their micronotes with a higher factual correctness (93.2%) while accurately reflecting their writing style. While using NoTeeline, participants experienced significantly reduced mental effort, captured satisfactory notes while writing 47% less text, and completed notetaking with 43.9% less time compared to a manual notetaking baseline.

翻译：视频已成为信息共享与消费的主流媒介形式。然而，观看视频时记录笔记需要耗费大量时间与精力。为此，我们提出了一种新颖的交互式系统NoTeeline，用于生成实时个性化笔记。该系统允许用户快速记录关键点（微笔记），这些关键点会自动扩展为完整的笔记，既涵盖用户微笔记的内容，又保持与用户写作风格的一致性。在一项受试者内研究（N=12）中，我们发现NoTeeline能帮助用户创建高质量的笔记，这些笔记在保持更高事实准确率（93.2%）的同时，精准捕捉了微笔记的核心内容，并真实反映了用户的写作风格。使用NoTeeline时，参与者体验到显著降低的认知负荷，在文本输入量减少47%的情况下仍能获得满意的笔记记录效果，且相较于手动笔记记录基线，完成笔记记录任务的时间缩短了43.9%。
