This research explores how verbal distractions influence the learning process during an assembly task. Participants first practiced a pattern replication task until their performance stabilized, then repeated it under conversation-based distractions. A camera system with ArUco marker tracking and timer-based monitoring was used to assess both accuracy and task completion time. The results showed that while distractions significantly increased task duration, they did not negatively affect the quality of the final product. These findings underline the importance of considering cognitive load in industrial environments and demonstrate the effectiveness of video-based monitoring for evaluating human performance.

Due to high turnover in industry, efficient onboarding and supportive systems are essential. This research investigates how operators learn a new task and how they interact with different types of work instructions. In a disassembly experiment, we measured task completion time, error rates, and attention to the instructions. Our findings show that simplified work instructions introduced after an initial training phase can significantly reduce task duration without increasing mistakes. These results highlight the potential of instruction abstraction in supporting operator performance during repetitive tasks.
