Bimanual Manipulation of a Complex Object with Internal Dynamics

Object manipulation often requires coordination between hands and adaption to the dynamic characteristics of the object. When manipulating the same object, the two hands can have either symmetric or asymmetric impacts on the object's trajectory. In this work, we used a bimanual manipulation task of a complex object with internal dynamics to examine how symmetric or scaled-down control of one of the hands affects the coordination between hands. Our result shows that participants are able to quickly adapt to different conditions but the coordination between the two hands changes very little.     «
