It is necessary to clarify the nature of the hand action representations automatically elicited by familiar handled objects, such as a teapot. By past experience, we have interaction of objects and the observer, regulation grasping action, and congruent orientation of observer’s body and object. To understand the effective grasping of everyday tools, it is necessary to consider the arrangement of the observer’s hand and the tools being used. Effective grasping was tested using various arrangements of familiar or unfamiliar everyday tools and hands were positioned appropriately to perform the grasping action. Participants were shown pictures of familiar or unfamiliar objects and asked to judge whether or not they could grasp the objects. The results showed that familiarity with the tools affected the errors in grasping judgment.
