Determination of Time-Sharing Efficiency in an Industrial Visual Inspection Task

This pilot experiment examined two variations of a secondary task used in determining the time-sharing ability of an inspector searching for defects on printed circuit boards. The methodology incorporated mathematical PRF and POC models, revealing that greater efficiencies were achieved with the easier secondary task. The inspection task was determined to be data-limited. Results will be used in the design of a mental workload study in visual inspection.
