interactor

One who engages

An interactor is a person or thing that interacts with something else—typically a user engaging with a system, interface, or experience.

The term appears in computing, design, and research contexts: The interactor navigates the virtual environment using gestures.

In interactive fiction and games, the interactor is the participant whose choices shape the narrative.
