Request from robot to person in information sharing

We proposed a projection function as a method of information sharing between a person and a coexistent robot. The projection function means that an image of the simulated robot motion is projected in the task environment for cooperation between the person and the robot. We categorize the information which should be shared by the robot and the coexisting person into 3 contents: 1) knowledge about the task environment; 2) intention of the robot and the person´s motion in the task process; and 3) request from one to the other to cooperate to do the task. We introduce a request from the robot to the person as a new interaction mode for the coexistent robotic system
