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… (More)
We present HuddleLamp, a desk lamp with an integrated RGB-D camera that precisely tracks the movements and positions of mobile displays and hands on a table. This enables a new breed of… (More)
While Mark Weiser's vision of ubiquitous computing is getting closer to reality, a fundamental part of it - the interconnection of devices into a "ubiquitous network" - is not achieved yet.… (More)
We introduce the interaction library Squidy, which eases the design of natural user interfaces by unifying relevant frameworks and toolkits in a common library. Squidy provides a central design… (More)
We introduce Blended Interaction, a new conceptual framework that helps to explain when users perceive user interfaces as “natural” or not. Based on recent findings from embodied cognition and… (More)
Using affinity diagramming as an example, we investigate reality-based interfaces for supporting creative group work. Based on an observational study grounded in the reality-based interaction… (More)
Recent findings from Embodied Cognition reveal strong effects of arm and hand movement on spatial memory. This suggests that input devices may have a far greater influence on users' cognition and… (More)
We present a new visualization approach for metadata combining different visualizations into a so-called SuperTable accompanied by a Scatterplot. The goal is to improve user experience during the… (More)
In this paper, we address the problem of designing for participation and parallel interaction with a walk-up-and-use tabletop system in a public exhibition environment. Motivated by the work practice… (More)
Corporate software development faces very demanding challenges, especially concerning the design of user interfaces. Collaborative design with stakeholders demands modeling methods that everybody can… (More)
