Validation of a new reaching algorithm for the Boeing developed CATIA Human Model was conducted prior to production release of the software. The validation covered both normal and maximum reach capabilities. Human subject and computer generated reach data were compared. For normal reaching, both the subjects and human models reached to the targets that were within reach, but the final body positions were not the same. For the maximum reach validation, problems with both the software and the data collection technique were discovered. Despite the discrepancies and problems found, the CATIA human model was found suitable for its intended use.
