Grip-force modulation in human-to-human object handovers: effects of sensory and kinematic manipulations

Abstract From a motor control perspective, human-to-human object handovers can be described as coordinated joint-actions transferring the power over an object from a passer to a receiver. Although, human-to-human handovers are very reliable in terms of success, it is unclear how both actors plan and...
