Abstract

This study aims to formulate a mathematical model of the human arm movement by modifying and extending the virtual force field that will best describe the trajectory of arm movement in weight sensory response. An experiment was conducted to determine the effect of weight sensory response in the trajectory of human arm movement. The experiment involves changing the weight of the handheld load during every start of performance of a reaching movement and then the virtual force field was modified. It was found that as weight is added. the velocity of arm movement decreases and when the subject perceived the change in weight. the velocity suddenly was increased. Furthermore, when more weight was added, the velocity was decreased. The resulting trend of the velocity profile in the experiment was the basis for the formulation of the mathematical model of the human arm movement. The formulated model was simulated and then compared with the experimental result and analyzed. The formulated model (Extended F2REACI-1) properly described the experimental behavior of the trajectory by showing the trend of the velocity profile from simulations which satisfies the resulting trend of the velocity profile in the experiment.
