  Large language models (LLMs) have demonstrated remarkable potential in
natural language understanding and generation, making them valuable tools for
enhancing conversational interactions. However, LLMs encounter challenges such
as lacking multi-step reasoning capabilities, and heavy reliance on prompts. In
this regard, we introduce a prompt-refinement system named PromptMind, also
known as "Prompt Your Mind", to provide an automated solution for generating
contextually relevant prompts during conversations. PromptMind enhances the
overall interaction between humans and chatbots through an automatic prompt
suggestion and an automatic prompt refinement. To assess the effectiveness of
PromptMind, we designed three interaction tasks to evaluate emotional support,
advice acquisition, and task-oriented interactions during human-chatbot
interactions. The results demonstrated that PromptMind reduced mental demands
during interactions and fostered enhanced performance and social connections
between users and chatbots. In summary, our findings indicate that PromptMind
acts as a bridge, facilitating smoother information exchange and enhancing the
usability of chatbot interactions.
