This paper presents the results of a study the authors conducted together over a year in order to identify key issues of ESA’s (European Space Agency) potential for a deployment of Virtual Reality training environments within space operations. Typically, ESA simulates several operations using DES like systems that need to be linked to a VR environm...
In this paper we present and discuss common visual elements in Augmented Reality which create a distinct information context while presenting them in either video- or optical-see-though setups, and which align with the promise of AR being able to bridge the gap between real world objects and the digital information space about them.
Experiencing 3D models of historical reconstructions and places is still an active issue considering the wide variety of displaying and interaction devices for immersive Virtual Reality. Moreover, as standards are missing, the sheer endless possibilities to map e.g. gestural input and other input reads to particular needs in navigation and selectio...
This paper presents the results of ongoing work realizing a mobile virtual museum that enables the connection between locally dispersed museums, collections and artefacts. The mobile application interconnects venues, objects and stories for an enhanced user experience and increased learnability inside the museum. It contextualizes information and r...
This work provides an insight into the basics of 3D applications in conjunction with various customer devices. In this case, the application is a 3D planetarium of our solar system for a museum.

Although AR has a long history in the area of maintenance and service-support in industry, there still is a lack of lightweight, yet practical solutions for handheld AR systems in everyday workflows. Attempts to support complex maintenance tasks with AR still miss reliable tracking techniques, simple ways to be integrated into existing maintenance...
Optical see through head mounted displays (OST-HMD) are ever since the first days of Augmented Reality (AR) in focus of development and in nowadays first affordable and prototypes are spread out to markets. Despite common technical problems, such as having a proper field of view, weight, and other problems concerning the miniaturization of these sy...
CHESS is a research prototype system aimed at enriching museum visits through personalized interactive storytelling. Aspiring to replace traditional exhibit-centric descriptions by story-centric cohesive narrations with carefully-designed references to the exhibits, CHESS follows a plot-based approach, where the story authors create stories around...
In this work, we present the CHESS research prototype system which offers personalized, interactive digital storytelling experiences to enhance museum visits, demonstrating the authoring and visiting experiences.
With the idea to design augmented reality experiences that attract and inform, and which are also seamlessly incorporated into interactive museum narratives, this paper explores finding the appropriate balance between attraction, interactivity and information mediation from the user's point of view. Within the scope of research project CHESS, we've...
The rapid development of geo-referenced information changed the way on how we access and interlink data. Smartphones as enabling devices for information access are main driving factor. Thus, the hash key to information is the actual position registered via camera and sensory of the mobile device. A rising technology in this context is Augmented Rea...

In this paper we present the design of handheld Augmented Reality (AR) experiences that are seamlessly incorporated into interactive museum narratives, specifically for the Acropolis Museum. The experiences start by forming a visitor profile that later dynamically adapts the narrative, including the AR activities, to the user`s behaviour. In this c...
Manual and automatic reconstruction of cultural assets are well-established fields of research. Especially with the recent introduction of methods such as KinectFusion even low cost sensors can be employed to create digital copies of the environment. However, experiencing these 3D models is still an active issue considering the wide variety of inte...
In this paper, we present a generic and affordable approach for an automatized and markerless capturing of movements in dance, which was developed in the Motion Bank / The Forsythe Company project (www.motionbank.org). Thereby within Motion Bank we are considering the complete digitalization workflow starting with the setup of the camera array and...
In our paper we are proposing a method for contextual information filtering based on the user's movement and location in order to enable the intuitive usage of an "internet of things" via augmented reality (AR) without information overload. Similar to Ray & Charles Eames' "Power of Ten" and Jef Raskin's "Zooming Interface" we are displaying seamles...
Recent developments in depth sensor technology enable developers to use skeletal input in interactive 3D environments with high user fluctuation like museum exhibits. However, the question of how to use natural user input and body movement to control rich interactive and immersive environments remains and demands more intuitive solutions due to the...
We present our novel generic approach for interfacing web components on mobile devices in order to rapidly develop Augmented Reality (AR) applications using HTML5, JavaScript, X3D and a vision engine. A general concept is presented exposing a generalized abstraction of components that are to be integrated in order to allow the creation of AR capabl...
The success of smartphone technologies changed the way information is processed as more and more geo-referenced structures are emerging linking information to specific locations within our environment. Thereby, Augmented Reality has become a key technology as it analyses the smartphone sensor data (camera, GPS, inertial) to derive the detailed pose...
In this demo description we present X3DOM, which is an open source framework and runtime system to support the ongoing discussion in the Web3D and W3C communities how an integration of HTML5 and declarative 3D graphics can look like by including X3D elements as part of the HTML5 DOM tree. The goal here is to have a live X3D scene-graph integrated i...
With ”House of Olbrich” we present an iPhone Augmented Reality (AR) app that visualizes the compelling history of Darmstadt's unique Jugendstil (Art Nouveau) quarter with video-see through Augmented Reality. We propose methods for enabling high performance computer vision algorithms to deploy sophisticated AR visuals on current generation Smartphon...
As the complexity of maintenance tasks can be enormous, the efficient training of technicians in performing those tasks becomes
increalingly important. Maintenance training is a classical application field of Augmented Reality explored by different research
groups. Mostly technical aspects (e.g tracking, 3D augmentations) have been in focus of this...
We present a scalable architecture, which implements and further evolves the HTML/X3D integration model X3DOM introduced in [Behr et al. 2009]. The goal of this model is to integrate and update declarative X3D content directly in the HTML DOM tree. The model was previously presented in a very abstract and generic way by only suggesting implementati...
For simulating communicative behavior, realistic appearance and plausible behavior is important. Postures and mimics also
reflect emotional behavior. There exist various models of emotion, like the psycho-evolutionary theory developed by Plutchik
[1], or Ekman’s FACS. But most models are only suited for muscular expressions. A more unattended field...

Very few explore generic high level interfaces for multi-touch applications. In this paper we present a comprehensive hardware...
Because of the difficulties in navigating public transport networks and
finding out about available activities, cultural tourists tend to follow a pre-planned
itinerary and to visit a fairly small set of well known attractions. An analogous
situation emerges at the cultural heritage sites themselves: while cultural heritage
sites typically have a l...
Museums often lack the possibility to present archaeological or cultural heritage sites in a realistic and interesting way. Thus are proposing a new way to show augmented reality applications of cultural heritage sites at remote places like museums.
