Interrogating AI: Characterizing Emergent Playful Interactions with ChatGPT

In an era of AI's growing capabilities and influences, recent advancements are reshaping HCI and CSCW's view of AI as mere tools. Playful interactions with AI systems naturally emerged as a way for users to make sense of the ever-changing technology. However, these emergent and playful interactions are underexamined. We target this gap by investigating playful interactions exhibited by users of a recently trending powerful AI technology, ChatGPT. Through a thematic analysis of 372 user-generated posts on the ChatGPT subreddit, we found that a substantial portion of user discourse revolves around playful interactions. The analysis further allowed us to construct a preliminary taxonomy to describe these interactions, categorizing them into six types: reflecting, jesting, imitating, challenging, tricking, and contriving; each included sub-categories. Overall, this study contributes to the field of HCI and CSCW by illuminating the multifaceted nature of playful interactions with AI, underlining their significance in shaping the human-AI relationship.
