ABSTRACT: Creating and maintaining scenes for mobile Augmented Reality browsers can be a challenging and time consuming task. The timeliness of digital information artifacts connected to changing urban environments require authors to constantly update the structural representations of augmented scenes or to accept that the information will soon be outdated. We investigated approaches for retrieving multimedia content and relevant web services for mobile Augmented Reality applications at runtime. Using semantic web technologies we are able to postpone the retrieval of actual media items to the moment a user actually perceives an augmented scene. This allows content creators to augment a scene only once and avoid continous manual updates.]]>

Our presentation on mobile interactive hologram verification at ISMAR 2013 in Adelaide, Australia ABSTRACT: Verification of paper documents is an important part of checking a person’s identity, authorization for access or simply establishing a trusted currency. Many documents such as passports or paper bills include holograms or other view-dependent elements that are difficult to forge and therefore are used to verify the genuineness of that document. View-dependent elements change their appearance based both on the viewing direction as well as dominant light sources, thus it requires special knowledge and training to accurately distinguish original elements from forgeries. We present an interactive application for mobile devices that integrates the recognition of the documents with the interactive verification of viewdependent elements. The system recognizes and tracks the paper document, provides user guidance for view alignment and presents a stored image of the element’s appearance depending on the current view of the document also recording user decisions. We describe how to model and capture the underlying spatially varying BRDF representation of view-dependent elements. Furthermore, we evaluate this approach within a user study and demonstrate that such a setup captures images that are recognizable and that can be correctly verified.]]>

Jens Grubert delivered the presentation on August 28th, 2013 during the 15th edition of MobileHCI, International Conference on Human-Computer Interaction with Mobile Devices and Services in Munich, Germany. ABSTRACT: We repeated a study on the usage of a magic lens and a static peephole interface for playing a find-and-select game in a public space. While we reproduced the study setup and procedure the task was conducted in a public transportation stop with different characteristics. The results on usage duration and user preference were significantly different from those reported for previous conditions. We investigate possible causes, specifically the differences in the spatial characteristics and the social contexts in which the study took place.]]>

While this user interface metaphor represents an instance of cross-media information spaces the specific context of its use has not yet been carefully studied, resulting in productions generally relying on trial-and-error approaches.

Jens Grubert delivered the presentation on September 29th, 2012 during the 14th edition of MobileHCI, International Conference on Human-Computer Interaction with Mobile Devices and Services in San Francisco, California, USA. ABSTRACT: Magic lens and static peephole interfaces are used in numerous consumer mobile phone applications such as Augmented Reality browsers, games or digital map applications in a variety of contexts including public spaces. Interface performance has been evaluated for various interaction tasks involving spatial relationships in a scene. However, interface usage outside laboratory conditions has not been considered in depth in the evaluation of these interfaces. We present findings about the usage of magic lens and static peephole interfaces for playing a find-and-select game in a public space and report on the reactions of the public audience to participants‟ interactions. Contrary to our expectations participants favored the magic lens over a static peephole interface despite tracking errors, fatigue and potentially conspicuous gestures. Most passersby did not pay attention to the participants and vice versa. A comparative laboratory experiment revealed only few differences in system usage.]]>
