We present a model that allows to directly integrate X3D nodes into HTML5 DOM content. This model tries to fulfill the promise of the HTML5 specification, which references X3D for declarative 3D scenes but does not define a specific integration mode. The goal of this model is to ease the integration of X3D in modern web applications by directly mapping and(More)
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 implementation(More)
We introduce "Facet-Streams", a hybrid interactive surface for co-located collaborative product search on a tabletop. Facet-Streams combines techniques of information visualization with tangible and multi-touch interaction to materialize collaborative search on a tabletop. It harnesses the expressive power of facets and Boolean logic without exposing users(More)
We present a proof-of-concept of a mobile navigational aid that uses the Microsoft Kinect and optical marker tracking to help visually impaired people find their way inside buildings. The system is the result of a student project and is entirely based on low-cost hardand software. It provides continuous vibrotactile feedback on the person's waist, to give(More)

Interactive spaces with multiple networked devices and interactive surfaces are an effective means to support multi-user collocated collaboration. In these spaces, surfaces like tablet PCs, tabletops, or display walls can be combined to allow users to interact naturally with their personal or shared information, e.g. during presentation, discussion, or(More)
This paper introduces ZOIL (Zoomable Object-Oriented Information Landscape), a design paradigm and software framework for post-WIMP distributed, zoomable and object-oriented user interfaces. We present ZOIL’s design principles, functionality and software patterns to share them with other researchers. Furthermore, ZOIL’s implementation as a software(More)
Multi-touch interaction on tabletop displays is a very active field of todays HCI research. However, most publications still focus on tracking techniques or develop gesture configurations for a specific application setup using a small set of simple gestures. In this work we present a new approach to easily set up the recognition of even complex gestures for(More)
Application programming interfaces (APIs) are the interfaces to existing code structures, such as widgets, frameworks, or toolkits. Therefore, they very much do have an impact on the quality of the resulting system. So, ensuring that developers can make the most out of them is an important challenge. However standard usability evaluation methods as known(More)
Multi-touch interaction on tabletop displays is a very active field of todays HCI research. However, most publications still focus on tracking techniques or develop a gesture configuration for a specific application setup. Very few explore generic high level interfaces for multi-touch applications. In this paper we present a comprehensive hardware and(More)
