PromptCanvas：基于动态小部件的可组合提示工作空间，用于创意写作的探索与迭代 (PromptCanvas: Composable Prompting Workspaces Using Dynamic Widgets for Exploration and Iteration in Creative Writing)

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.

翻译：我们提出了PromptCanvas这一概念，它将提示过程转化为无限画布上基于小部件的可组合交互体验。用户能够生成、定制并排列代表文本不同侧面的交互式小部件，从而对AI生成内容实现更精细的控制。PromptCanvas支持通过系统建议、用户提示或手动输入创建小部件，提供了一个可根据个人需求灵活调整的环境。这使用户能够更深入地参与创作过程。在一项包含18名参与者的实验室研究中，PromptCanvas在创造力支持指数上超越了传统对话式用户界面。参与者发现该系统降低了认知负荷，表现为心理需求和挫败感的减少。定性反馈表明，可视化的思维组织与便捷的迭代过程促进了新视角和创意的产生。后续实地研究（N=10）进一步验证了这些结果，展现了动态可定制界面在提升人机协同写作效能方面的潜力。
