Abstract

Visualizing occluded objects is a useful applications of Mixed Reality (MR), which we call "see-through vision." For this application, it is important to display occluded objects in such a manner that they can be recognized intuitively by the user.Here, we evaluated five visualization methods for see-through vision that help the user to intuitively recognize occluded objects in outdoor scenes: "elimination of occluding object," "ground grid," "overlaying model of occluding object," "top-down view," and "on-off switching of MR display." As we applied a new handheld MR device for outdoor see-through vision, we conducted subjective experiments to determine the best combination of methods. The experimental results indicated the combination of showing the ground grid, overlaying the wire-frame models of occluding objects, and top-down view to be optimal, while it is not necessary to display occluding objects for outdoor see-through vision with a handheld device, because users can see them with the naked eye.
