Abstract
SAMMIE and CAR are computer-based human-modelling systems which allow anthropometric evaluations to be performed in 3-dimensional environments. Previous assessments have shown that SAMMIE was a better predictor than CAR of reaches made forward from and ipsilateral to the body. Despite SAMMIE's good performance, its predictions may have been hampered by a software limitation which did not allow shoulder movement. This paper presents an algorithm to correct this deficiency. The algorithm was written (using SAMMIE's macro-processing facility) to allow shoulder movement during reaches. It embodies anthropometric principles and uses parameters empirically derived from large samples of male and female anthropometry data. Without shoulder movement, SAMMIE under-estimated male subject data for ipsilateral reaches by 5.4 cm. When shoulder movements were allowed, its reach estimates for the same subjects were correct within 0.8 cm.
