This study investigates the efficacy of the innocuous pain stimulation on the success rate of grasping an object in comparison to the efficacy of force and visual feedback. In our human-subject experiments, a microcontrolled haptic device is employed to provide the innocuous pain stimulus to human arm when the positioning of the virtual fingers exceeds the boundaries of the virtual object. Grasping performance of the subjects is evaluated based on the measured error, which is the level of intrusion of fingers with respect to the boundary of the circle. While performing the task, innocuous pain stimulation is applied to the subjects' arm as a function of the measured error through the hand exoskeleton device. Preliminary results show that innocuous pain stimuli provide more successful hand positioning and more optimal gripping level compared to force and visual stimuli.
