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 framework, we identified power vs. reality tradeoffs that can be addressed to find a close fit to embodied practice. Using this knowledge, we designed and implemented(More)
[1] The Faroe Bank Channel (FBC) is the deepest connection between the Atlantic Ocean and the Nordic Seas. This work describes the dynamic properties of the plume of dense overflow water descending from the Faroe Bank Channel using time series data for velocity and temperature from a network of 25 moorings deployed west of the Faroe Bank Channel between(More)
When the user interface (UI) has to be specified, a picture is worth a thousand words, and the worst thing one can do is attempt to write a natural language specification for it. Nevertheless, this practice is still common, and it is therefore a difficult task to move from text-based requirements and problem-space concepts to a final UI design, and then(More)
We introduce a UI specification tool that interactively integrates interdisciplinary and informal modelling languages with different fidelities of UI prototyping. Our innovative experimental tool, called INSPECTOR, is the first tool that assembles models and design into a UI specification with a zoom-based visualization approach. In our research we analyze(More)
In this paper, we propose Blended Interaction as a conceptual framework for the design of interactive spaces. We argue that for realizing a natural computer-supported collaboration in smart environments or interactive spaces, designers must achieve a holistic understanding and design of the users' individual interactions, social interactions, workflows and(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 cognitive linguistics, Blended Interaction provides a novel and more accurate description of the nature of human–computer interaction (HCI). In particular, it(More)
In this paper we present our approach to support artifact-mediated collaboration in interaction design. We argue that the extensive number and the diversity of artifacts created and reflected upon during collaborative design activities as well as transitions between physical and digital representations impose both a challenge and opportunity for supporting(More)
Using affinity diagramming as an example, we investigate interaction techniques for supporting collaborative design activities. Based on an observational study, we identified design guidelines that need to be addressed to find a close fit to embodied practice. Using this knowledge, we designed and implemented AffinityTable, a hybrid surface for supporting(More)
In this paper we describe IdeaVis, a novel approach for supporting co-located sketching sessions. Our system is based on digital pen & paper for augmenting the traditional paper-based workflows of sketching sessions. An additional focus & context visualization is used to support creative facilitators in exploring and examining the design activity,(More)
In this paper we describe a system design for supporting creative group activities using distributed displays and multimodal interaction. We describe the rationale behind our approach and proposed interaction techniques for supporting collaborative sketching. Our goal is to understand how the interface metaphor, display space and interaction modalities may(More)
