用关键帧控制生成叙事，让写作更可控、透明且有参与感。
Narrative Keyframing for Generative Creative Writing
- 在故事关键点设置三类关键帧：情节、角色变化和视角。
- 用户通过关键帧引导AI生成中间段落，实现细粒度控制。
- 适合想掌控创作节奏的作家与教学场景使用。
我们提出叙事关键帧技术，一种用于辅助创意写作的交互方法，允许作者在故事特定时刻设定不同类型的叙事约束，再由AI生成其间的内容。该方法受动画中关键帧技术启发，将故事规划与生成文本的自适应控制相结合。探索了三种关键帧类型：情节关键帧定义故事中的重要事件，角色关键帧表示角色随叙事的变化，视角关键帧通过第一人称叙述捕捉角色对事件的主观体验。情节与角色关键帧提供了比以往AI写作工具更可定制、可迭代、精细的高层条件控制方式；视角关键帧则通过第一人称叙述作为中介，新增了对人物塑造与聚焦方式的控制手段。通过用户研究，我们验证了叙事关键帧能支持更可控、透明且富有参与感的生成式写作体验。
原文摘要 · Abstract (English)
We introduce narrative keyframing, an interaction technique for AI-assisted creative writing that lets writers specify different types of narrative constraints at selected moments in a story, then use AI to generate intervening prose. Inspired by the use of keyframing in animation, narrative keyframing offers a flexible way to connect story planning with adaptive control over generated text. We explore three types of keyframes: plot keyframes define significant events in a story, character keyframes represent how individual characters change over the narrative, and perspective keyframes capture how individual characters experience different events through first-person narratives. Plot and character keyframes offer a flexible way to adapt the type of high-level conditioning explored in previous AI writing tools to more customizable, iterative, and fine-scale control, while perspective keyframes add a new way to control characterization and focalization by using first-person narratives as an intermediary. Through a user study, we show that narrative keyframing supports a more controllable, transparent, and engaging way to use generative AI in creative writing.
