Influence of Background Color on Visual Inspector Performance in 3-Dimension Simulation Model
This research is aimed to study the influence of the background color which affects efficiency in visual inspection. The visual search simulation program was set to test the search for the letters X and Y assigned to represent defects and mixed up with other background letters in 4 different colors: white, yellow, red and blue. The test were conducted with 48 samples who passed the selection standard by having normal eyesight, more than 50% accuracy in defect search while the average search time was less than 50%. The samples were separated into 4 groups for defect search with 4 colors background. The result was shown that the different background colors affect the average search time for defect search in each screen and the accuracy of the search for different defects. The white background provided the inspector the highest defect search efficiency with the level of statistical significance at .05.
