After reading quite many popular science about QM, I still didn't get a real understanding of the difference between a so-called measurement and just an interaction (if there's actually any difference).
My understanding is that a measurement is an interaction "observed" in a way which allows to acquire information about it. The information itself does not need to be acquired by a sentient being, could just be recorded by a data recorder.
Just the fact that the information is there, and the possibility that at any eventual time it could be used, makes it a measurement and would for example destroy interference.
Just an interaction would be an interaction which is not recorded in any way, so that it will never be possible in the future to trace back information about what happened. In this case interference would not be destroyed.
Is this more or less correct? and if it is, does it not certainly and unavoidably put onto the table the famous role of consciousness in QM?
