This paper proposes a 3D map augmented photo gallery mobile application that allows user to virtually transit from 2D image space to the 3D map space, to expand the field of view to surrounding environments that are not visible in the original image, and to change viewing angles among different global registered images during the image browsing. The processing of images consists of two main steps: in the first step, the client application uploads an image to the GeoImage Engine which extracts the geo-metadata and returns them back to the client; in the second step, the client application requests augmented content from server, and then renders 3D view of images on the screen of mobile devices.

Augmented reality applications are gaining popularity due to increased capabilities of modern mobile devices. Creating AR content however is tedious and traditionally done on desktop environments by professionals, with extensive knowledge and/or even programming skills required. In this demo, we demonstrate a complete mobile approach for creating vision-based AR in both indoor and outdoor environment. Using hyperlinks, Web mashups are built to dynamically augment the physical world by normal users without programing skills.

In the past, several systems have been presented that enable users to view occluded points of interest using Augmented Reality X-ray visualizations. It is challenging to design a visualization that provides correct occlusions between occluder and occluded objects while maximizing legibility. We have previously published an Augmented Reality X-ray visualization that renders edges of the occluder region over the occluded region to facilitate correct occlusions while providing foreground context. While this approach is simple and works in a wide range of situations, it provides only minimal context of the occluder object. In this paper, we present the background, design, and implementation of our novel visualization technique that aims at providing users with richer context of the occluder object. While our previous visualization only employed one salient feature (edges) to determine which parts of the occluder to display, our novel visualization technique is an initial attempt to explore the design space of employing multiple salient features for this task. The prototype presented in this paper employs three additional salient features: hue, luminosity, and motion. We have conducted two evaluations with human participants to investigate the benefits and limitations of our prototype compared to our previous system. The first evaluation showed that although our novel visualization provides a richer context of the occluder object, it does not impede users to select objects in the occluded area; but, it also indicated problems in our prototype. In the second evaluation, we have investigated these problems through an online survey with systematically varied occluder and occluded scenes, focussing on the qualitative aspects of our visualizations. The results were encouraging, but pointed out that our novel visualization needs a higher level of adaptiveness.

We present a prototype mobile augmented reality client addition to the ¿Image Space¿ mixed reality media sharing service. We have explored how the real world aligned "mirror world" content from that service can be interacted with in-situ and identified two different use scenarios - geospatial media sharing and social connection. Since both the existing web based mirror world modality and the additional mobile augmented reality modality intersect at the common data, the combined service is as an example of how mirror worlds can be used to bridge the real and the virtual, and allow for interaction from either side of the reality continuum.
