  With ChatGPT's release, conversational prompting has become the most popular
form of human-LLM interaction. However, its effectiveness is limited for more
complex tasks involving reasoning, creativity, and iteration. Through a
systematic analysis of HCI papers published since 2021, we identified four key
phases in the human-LLM interaction flow - planning, facilitating, iterating,
and testing - to precisely understand the dynamics of this process.
Additionally, we have developed a taxonomy of four primary interaction modes:
Mode 1: Standard Prompting, Mode 2: User Interface, Mode 3: Context-based, and
Mode 4: Agent Facilitator. This taxonomy was further enriched using the "5W1H"
guideline method, which involved a detailed examination of definitions,
participant roles (Who), the phases that happened (When), human objectives and
LLM abilities (What), and the mechanics of each interaction mode (How). We
anticipate this taxonomy will contribute to the future design and evaluation of
human-LLM interaction.
