To be more specific, an example:
The customer relationship department of a company has 100 people to work on customer requests. This company has a system in which almost everything is automated for the user, and their only job is to answer simple "questions" on the screen, like if the customer has sent a specific document or not (a "yes or no" question).
The system user doesn't really need to think or have any critical thoughts about the process.
In portuguese we call this kind of "dumb" user a "button masher". I searched this term on Google, but all I got was results about simple games which require little effort from the user. But I wonder if this terminology can be applied to a non-gaming context as well, to describe the user.
