The development of large language models (LLMs) capable of following
instructions and engaging in conversational interactions sparked increased
interest in their utilization across various support tools. We investigate the
utility of modern LLMs in assisting professional writers via an empirical user
study (n=30). The design of our collaborative writing interface is grounded in
the cognitive process model of writing that views writing as a goal-oriented
thinking process encompassing non-linear cognitive activities: planning,
translating, and reviewing. Participants are asked to submit a post-completion
survey to provide feedback on the potential and pitfalls of LLMs as writing
collaborators. Upon analyzing the writer-LLM interactions, we find that while
writers seek LLM's help across all three types of cognitive activities, they
find LLMs more helpful in translation and reviewing. Our findings from
analyzing both the interactions and the survey responses highlight future
research directions in creative writing assistance using LLMs.

通过实证用户研究 (n=30)，我们调查了现代大型语言模型 (LLMs) 在协助专业作家方面的效用，发现作家在规划、翻译和审阅等认知活动中都寻求 LLMs 的帮助，尤其在翻译和审阅方面 LLMs 更为有帮助，同时我们的研究结果也强调了利用 LLMs 进行创意写作辅助的未来研究方向。
