“…Therefore, our blending method may be useful as a new X-ray visualization technique. X-ray visualization methods are extensively studied to make virtual information seen through real foreground surfaces in AR or MR applications [16,21]. It should be noted, however, that our model of perceptual transparency gives no assurance to provide good results when a virtual object is completely occluded.…”

One of the challenges in mixed reality (MR) applications is handling contradictory occlusions between real and virtual objects. The previous studies have tried to solve the occlusion problem by extracting the foreground region from the real image. However, real-time occlusion handling is still difficult since it takes too much computational cost to precisely segment foreground regions in a complex scene. In this study, therefore, we proposed an alternative solution to the occlusion problem that does not require precise foreground-background segmentation. In our method, a virtual object is blended with a real scene so that the virtual object can be perceived as being behind the foreground region. For this purpose, we first investigated characteristics of human transparency perception in a psychophysical experiment. Then we made a blending algorithm applicable to real scenes based on the results of the experiment.

“…Using simple overlays for visualizing underground objects via an AR XRay view can cause perceptional issues, such as the impression of underground objects floating over the ground. To avoid these problems, it is essential to either decide which parts of the physical scene should be kept and which parts should be replaced by virtual information [13] or which kind of additional virtual depth cues can be provided [14]. A comprehensible visualization should provide users with essential perceptual cues to understand the relationship of depth between hidden information and the physical scene.…”

Abstract. Most civil engineering tasks require accessing, surveying and modifying geospatial data in the field and referencing this virtual, geospatial information to the real world situation. Augmented Reality (AR) can be a useful tool to create, edit and update geospatial data representing real world artifacts by interacting with the 3D graphical representation of the geospatial data augmented in the user's view.One of the main challenges of interactive AR visualizations of data from professional geographic information systems (GIS) is the establishment of a close linkage of comprehensible AR visualization and the geographic database that allows interactive modifications. In this paper, we address this challenge by introducing a flexible data management between GIS databases and AR visualizations that maintain data consistency between both data levels and consequently enables an interactive data roundtrip. The integration of our approach into a mobile AR platform enables us to perform first evaluations with expert end-users from utility companies.

“…Another methodology is based on the evaluation of real occluding objects' shape by geometrical tracking using stereo matching (Hayashi et al 2005, Fortin andHebert 2006) or direct image segmentation (Tian et al 2010, Zollmann et al 2010.…”
