Customizing the balance between user and system agency in human-AI co-creative processes

The computational creativity community has long been engaging with the challenge of achieving a balance between unobtrusiveness and interjection in the interaction dynamics between computational systems and human users. This challenge has recently become more urgent due to the pervasive adoption and use of Generative AI tools in creative practices. This paper contributes to- ward understanding the trade-off between user and system agency, building on a user-centered co-creativity frame- work that identifies key dimensions responsible for the modulation of agency between users and AI in co-creative processes. We consider how the inclusion of these di- mensions in co-creativity tools can help us achieve core values in human-AI interaction, such as alignment, co- adaptation, and explainability. We close the paper by suggesting a way to tailor co-creative experiences, describing the profiles of different AI personae that users might choose to interact with.
