A Hydraulic excavator is commonly used in construction site. However, its user interfaces by operation levers is difficult to operate skillfully. In this study, we propose a virtual operating experience system of a hydraulic excavator using an RC excavator and augmented reality technique for skill training and evaluation of the operation. The proposed system realizes a virtual cockpit view by using an omni-directional camera and a head mounted display. It enables the similar operating feeling as that of a real excavator. We compare an expert and beginners by using the proposed system and discuss the difference.
