What is Human in, on and out of the loop?

The three terms distinguish where the human sits in the process. Human in the loop means nothing happens without human approval. Human on the loop means the system acts by itself while a person observes and can intervene or stop it. Human out of the loop means the system acts in production without oversight.

The classification matters for evidence. Art. 14 of the EU AI Act requires effective human oversight for high-risk systems, and oversight is only effective if the person understands the output, has enough time and can actually stop the system. An approval button without a basis for the decision does not meet the requirement.
