Abstract
ABSTRACT Two methods of presenting product for visual inspection were compared by measuring the accuracy of the decision process. Simulated products (plastic balls) with random defects were video taped from two different directions (side-to-side and moving toward the inspector). Fifty subjects that viewed the tapes had a 23% increase in their decision accuracy when the product was moving toward them compared to side-to-side. Slow motion analysis of the tape showed that 15% more defects were visible from the end than from the side. The difference between the performance of the inspectors and the actual increase in defects visible to them indicated that ergonomic principles raised the accuracy of the decision process by eight percentage points. Results from an equation developed for calculating the visible surface area of the balls compared favorably with the number of defects visible (13% compared to 15% improvement).
