Abstract

Human motion analysis has a wide range of applications in sports, medicine and robotics, thus the study aims to formulate a mathematical model by modifying and extending the virtual force field that will best describe the trajectory of arm movement in weight sensory response. The experiment involves changing the weight of the handheld load every performance of a reaching movement and then the virtual force field was modified. The formulated model was simulated then compared and analyzed if it properly described the trajectory. Experimentally, it was observed that as weight is added, velocity of arm movement decreases but when the subject perceived the change in weight, it suddenly increased and when more weight was added, the velocity decreased. The formulated model (Extended F2REACH) properly described the experimental behavior of the trajectory by showing the trend of the velocity profile from simulations which satisfies the trend of the velocity profile from the experiment.
