Visualization Methods for Outdoor See-Through Vision

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 seethrough 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 seethrough...
