Research Abstract	When we manipulate tools or objects, the central nervous system receive force information from tactile sensors in hand and from proprioceptive signals in muscles. Such somatosensory information is crucial not only for predicting states of our movements but also for motor planning. To control tools dexterously we must execute our movements in interaction with the physical environment resulting in an appropriate force trajectory. Here we focus on the role of force sense information on planning a force interactive task. To test the claim that human use tactile information of palm and fingers for planning, we conducted comparisons between experimental and simulated data using a crank-rotation task. Our results show a close matching between the measured and predicted data.
