Abstract
A video system was developed to record the actions of inspectors during a visual and tactile inspection task in an automobile line plant. The system consisted of two video cameras and recorders operated synchronously. The recordings were analysed with a video motion analyser. The search behaviour of the inspectors was described by using four items of information derived from each video frame. As a consequence, the inspection task was resolved into elements with a discrimination of 1/30 s. Comparisons were made between the behaviour when flaws were deleted, missed and when there were no flaws and the search strategy required to locate flaws in the product was described. The recommended values of search parameters were estimated and this recommended search strategy was presented in a form understandable to the inspectors.
