Two interaction techniques were evaluated to promote longer prompt writing in chat-based generative AI assistants: requiring users to press and hold the submission button and requiring continuous slider movement when submitting a short prompt. A within-subjects experiment showed both techniques increased prompt length and raised psychological ownership relative to baseline. A second experiment added AI-generated expansion suggestions, further increasing prompt length without improving psychological ownership.","arXiv :2507 .03670v3 [ cs .HC] 12 Jul 2026  \nInteraction Techniques that Encourage Longer Prompts Can Improve Psychological Ownership when Writing with AI  \nNikhita Joshi∗ Cheriton School of Computer Science University of Waterloo Waterloo, Ontario, Canada [nvjoshi@uwaterloo.ca](nvjoshi@uwaterloo.ca)  \nDaniel Vogel  \nCheriton School of Computer Science University of Waterloo Waterloo, Ontario, Canada [dvogel@uwaterloo.ca](dvogel@uwaterloo.ca)  \n(a) motor cost: pump slider  \na cat named Ralph and his friend, a dog named Wilfred, meet a young boy named Sean one day in the forest.  \n\n| Move slider or type more to fill gauge |  |  |\n| --- | --- | --- |\n|  | 113 reps\u003Cbr> |  |\n\nThe progress bar must be green to submit a prompt.

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.  \n∗ Also with LISN, Université Paris-Saclay, CNRS, Inria.  \nThis work is licensed under a Creative Commons Attribution 4 .0 International License.
