I'm struggeling to find a concrete explanation/differentiation for both terms, "Nutzungsverhalten" and "Nutzerverhalten". I've seen Nutzungsverhalten being used mostly in the context of online-/media-usage, mainly denoting usage frequency and duration. In contrast, Nutzerverhalten being mostly used in the context of efficient energy use.
Intuitively, generally I would say Nutzungsverhalten denotes how something is used and Nutzerverhalten denotes how someone uses something.
My question is, is there actually a difference in general or are these just two terms for the same thing that are established differently in various contexts?
