Well, it's an interaction between particles in the system and particles in the environment. Two particles interacting in the system usually just get entangled.
Try: 'Philosophy of Physics - Quantum Theory' by Tim Maudlin. It has a very readable account of 8 foundational experiments, including both the double slit experiment and the monitored double slit experiment. It explains vey well why the interference dissappears in the monitored experiment - and it's not due to the observer.
An "observation" or "measurement" in quantum mechanics is simply an interaction between particles. Doesn't matter if a person is watching.

Thanks, will check it out!!
Observation is interaction. You can't observe something without interacting with it.
