Augmented Reality (AR) applications require knowledge about the real world environment in which they are used. This knowledge is often gathered while developing the AR application and stored for future uses of the application. Consequently, changes to the real world lead to a mismatch between the previously recorded data and the real world. New capturing techniques based on dense Simultaneous Localization...
In this paper, we explore techniques that aim to improve site understanding for outdoor Augmented Reality (AR) applications. While the first person perspective in AR is a direct way of filtering and zooming on a portion of the data set, it severely narrows overview of the situation, particularly over large areas. We present two interactive techniques to overcome this problem: multi–view AR and variable...
An investigation of the technology and human factors that drive augmented reality research describes recent developments in handheld AR, concentrating on localization, tracking, interaction, and visualization, and offers several examples illustrating the vast potential and important applications of AR. A related video can be seen here: http://youtu.be/ol371rIyUFY. It shows several real-world examples...
We investigate user experiences when using augmented reality (AR) as a new aid to navigation. We integrate AR with other more common interfaces into a handheld navigation system, and we conduct an exploratory study to see where and how people exploit AR. Based on previous work on augmented photographs, we hypothesize that AR is used more to support wayfinding at static locations when users approach...

In this paper we present the multi-display environment Deskotheque, which combines personal and tiled projected displays into a continuous teamspace. Its main distinguishing factor is a fine-grained spatial (i. e., both geometric and topological) model of the display layout. Using this model, Deskotheque allows seamless mouse pointer navigation and application window sharing across the multi-display...
