通过界面设计鼓励用户写更长提示，能增强对AI生成内容的归属感。
Interaction Techniques that Encourage Longer Prompts Can Improve Psychological Ownership when Writing with AI
- 用长按按钮或滑动条等交互方式引导用户输入更长提示。
- 实验显示提示长度增加后，用户心理归属感显著提升。
- 适合关注人机协作创作体验的研究者与产品设计师。
为AI助手生成故事时，撰写更长的提示能增强用户的心理归属感，即感觉内容属于自己。为促进用户写出更长提示，我们评估了两种修改聊天式生成式AI助手提示输入界面的交互技术：长按提交按钮，以及在提交短提示时持续上下滑动滑块。一项被试内实验研究了这些技术对提示长度和心理归属感的影响，结果表明，这些技术显著增加了提示长度，并带来了比基线方法更高的心理归属感。第二项实验进一步通过展示AI建议来扩展提示，虽使提示长度进一步增加，但未带来心理归属感的提升。结果表明，简单的界面改动能有效激发用户更多创作，提升心理归属感。
原文摘要 · Abstract (English)
Writing longer prompts for an AI assistant to generate a story increases psychological ownership, a user's feeling that the writing belongs to them. To encourage users to write longer prompts, we evaluated two interaction techniques that modify the prompt entry interface of chat-based generative AI assistants: pressing and holding the prompt submission button, and continuously moving a slider up and down when submitting a short prompt. A within-subjects experiment investigated the effects of such techniques on prompt length and psychological ownership, and results showed that these techniques increased prompt length and led to higher psychological ownership than baseline techniques. A second experiment further augmented these techniques by showing AI-generated suggestions for how the prompts could be expanded. This further increased prompt length, but did not lead to improvements in psychological ownership. Our results show that simple interface modifications like these can elicit more writing from users and improve psychological ownership.
