A spatial position tracker (SPT) for the human operator that performs robotic teaching at a work-site coexisting with a sensor-enhanced robot system is presented. The SPT measures the operator's position in real time by stereo processing of images from two CCD cameras with infrared filters and the operator's orientation, using a three-dimensional gyro. It enables the work-site operator to utilize augmented reality to understand the necessary task world information, including the sensor and end-effector's relative position and orientation without any special skills. In this paper, we describe the system configuration, discuss the detection accuracy, and present results for applying it to a multimodal teaching advisor currently being developed. |
