In the emerging field of close human-robot-collaboration the human worker needs to be able to quickly and easily understand data of the robotic system. To achieve this even for untrained personnel, we propose the use of a Spatial Augmented Reality system to project the necessary information directly into the users' workspace. The projection system consists of a fixed as well as a mobile projector mounted directly on the manipulator, allowing for visualizing data anywhere in the surroundings of the robot. By enabling the user to simply see the necessary complex information he can better understand the data and behavior of the robotic assistant and has the opportunity to analyze and potentially optimize the working process. Together with an input device, arbitrary interfaces can be realized with the projection system.
