CANCELED - Investigating the Effect of Guidance Modalities on Cognitive Workload and Workplace Task Performance
DescriptionThis study investigates how different guidance modalities—pictorial, video, and laser projection—affect cognitive workload and task performance in complex manufacturing assembly tasks. Using eye-tracking and subjective assessments, we measured cognitive load, accuracy, and completion times in a virtual reality block assembly task with 25 participants. Laser guidance resulted in the lowest blink rate, shortest completion times, and highest accuracy, indicating it is the least cognitively demanding and most efficient modality. Pictorial guidance showed the smallest pupil dilation, possibly due to eye fatigue. No significant differences in subjective workload were found, though laser was rated least taxing. These findings suggest laser-based guidance is optimal for reducing cognitive strain and enhancing efficiency, particularly for complex tasks, offering practical implications for improving manufacturing productivity.
