PromptCanvas: Composable Prompting Workspaces Using Dynamic Widgets for Exploration and Iteration in Creative Writing
- 将提示词转化为可拖拽、可定制的交互组件，构建无限画布上的创作环境。
- 实验显示用户在创造力支持指数上优于传统对话界面，认知负荷显著降低。
- 适合需要反复迭代和视觉化构思的AI辅助写作者，尤其适合协作场景。
我们提出PromptCanvas，一种将提示工程转变为基于组件、可组合的体验，运行于无限画布之上。用户可生成、自定义并排列代表文本不同方面的交互式组件，从而对AI生成内容实现更强控制。组件可通过系统建议、用户提示或手动输入创建，提供高度灵活的个性化环境，增强创作参与度。在18名参与者的小规模实验室研究中，PromptCanvas在创造力支持指数上优于传统对话式界面，参与者报告心理负担更轻、挫败感更低。定性反馈显示，思维的可视化组织和便捷迭代促进了新视角与创意的涌现。后续实地研究（N=10）验证了上述结果，凸显动态可定制界面在提升人机协同写作方面的潜力。
原文摘要 · Abstract (English)
We introduce PromptCanvas, a concept that transforms prompting into a composable, widget-based experience on an infinite canvas. Users can generate, customize, and arrange interactive widgets representing various facets of their text, offering greater control over AI-generated content. PromptCanvas allows widget creation through system suggestions, user prompts, or manual input, providing a flexible environment tailored to individual needs. This enables deeper engagement with the creative process. In a lab study with 18 participants, PromptCanvas outperformed a traditional conversational UI on the Creativity Support Index. Participants found that it reduced cognitive load, with lower mental demand and frustration. Qualitative feedback revealed that the visual organization of thoughts and easy iteration encouraged new perspectives and ideas. A follow-up field study (N=10) confirmed these results, showcasing the potential of dynamic, customizable interfaces in improving collaborative writing with AI.
