Handover actions refer to the transfer of an object from one person to another. In a recently published study by our research group, it was shown that people observe the movements of their partners in handover actions. In this task, for example, receivers pay attention to the velocity of the giver in order to obtain information about the handover object. We were able to show that receivers are able to estimate the weight of objects by observing the giver's kinematics. You can find the article in full length here.
