Bimanual Force Recreation: Humans perform several tasks throughout the day that require bimanual coordination and skill. Bimanual skills refer to the accuracy of any tasks performed using both arms, such as sewing, lifting, and driving. Depending on a person's occupation, there are varying skill levels required to perform their jobs in an accurate manner. An increasingly relevant problem for people who require high bimanual skills is the inaccuracy of self- recreated forces, or bimanual force perception. This study investigates the differences in bimanual force perception and force recreation using a haptic testing device. This device requires users to balance an input force from a lever with their right hand, and to recreate the same force on a stationary lever with the left hand. Five different finger configurations with five different forces were tested. The results of the experiment showed no statistically significant results which combined with the force data was found to be due to errors in the experimental process and participants deviation from the experimental procedure. This project led to further work that resulted in two papers: "Effect of Weight and Number of Fingers on Bimanual Force Recreation" and "Assessing the Effect of Experience on Bimanual Force Recreation".
