An approach to simulate human motion while performing a lifting task using an optimization technique was discussed. A lifting experiment was performed in an attempt to apply the model. Five subjects used two sizes of containers and were photographed while lifting the containers from floor to knuckle height and from the floor to shoulder height. Applying the model to the lifting tasks produced a model generated joint motion pattern which was comparable with the actual motion patterns. Based on the results of several applications of the model, the authors conclude that it may be feasible to develop simulation models to predict the path of the motion of body joints in two dimensions while performing a task such as lifting. These simulation models depend on optimization theory and techniques to solve problems about motion patterns required in the performance of a task to minimize a specific cost function or functions subject to a set of constraints.
