Hybrid display systems are those that combine different types of displays to exploit the complementary characteristics of the constituent display systems. In this paper, we introduce a hybrid system that combines a stereoscopic optical see-through head-mounted display (HMD) and a large projection display for an application in a multi-user ship painting training scenario. The proposed hybrid system's projection display provides a large FOV and a physical metaphor to the ship surface with natural depth perception, while the HMD provides personal and unoccluded display of the motion training guides. To quantify its effectiveness, we conducted a human subject experiment, comparing the subject's motion following task performance among three different display systems: large projection display, head-mounted display, and hybrid. The preliminary results obtained from the experiment has shown that given the same FOV, the hybrid system performed, despite problems with registration between the real and virtual worlds, up to par with the head-mounted display, and better than the projection display. Thus, it is expected that the hybrid display will result in higher task performance with the larger FOV factor available.
