Human-in-the-Loop (HITL) is a term from the fields of artificial intelligence, automation, and Industry 4.0. It describes workflows where humans and machines work closely together. While computers or AI automatically handle many tasks, there are often crucial steps where a human needs to intervene, review, or correct.
The goal of Human-in-the-Loop (HITL) is to leverage the benefits of automation without sacrificing human experience and judgement. Particularly in complex or safety-critical applications, human-machine collaboration is important to avoid errors.
A clear example: In a modern factory, AI-based quality control uses cameras to check products for defects. If the system detects an irregularity, the affected product is flagged, and an employee examines it more closely. The human ultimately decides whether the product is processed further or rejected.
Human-in-the-Loop (HITL) therefore ensures greater safety, more precise results, and enables companies to implement automation responsibly.
