    Dynamic ontology supported user interface for personalized decision support
    (2012) Bosch, Harald; Thom, Dennis; Heinze, Geoffrey-Alexeij; Wokusch, Stefan; Ertl, Thomas
    European citizens are increasingly aware of the influence of air quality and weather on their health and quality of life. At the same time, more environmental information is freely available through a plethora of websites, dedicated portals, and web services. In order to exploit these data for personal decisions one has to identify, retrieve, and combine the information that is relevant to one's personal situation, planned activity, and information need. Often, this task is hindered by different data formats, display styles and data resolutions. The PESCaDO system is a web-based decision support system addressing this issue. The inquiry to the system, as well as the system's result, can cover a broad range of environmental aspects and personal situations and is therefore quite complex. In this work we present a novel approach on how the system can actively assist users in all steps of the decision making process, especially by enhancing the user interaction. This approach combines an intelligent dialog steering method based on analyzing the domain ontology with flexible, dynamic data visualizations for a situation depending orchestration of data sources. Both aspects have been evaluated in on-line user studies, as well as with an expert evaluation of the whole system.

    Mid-Air gestures for window management on large displays
    (2015) Lischke, Lars; Knierim, Pascal; Klinke, Hermann
    We can observe a continuous trend for using larger screens with higher resolutions and greater pixel density. With advances in hard- and software technology, wall-sized displays for daily office work are already on the horizon. We assume that there will be no hard paradigm change in interaction techniques in the near future. Therefore, new concepts for wall-sized displays will be included in existing products. Designing interaction concepts for wall-sized displays in an office environment is a challenging task. Most crucial is designing appropriate input techniques. Moving the mouse pointer from one corner to another over a longer distance is cumbersome. However, pointing with a mouse is precise and common-place. We propose using mid-air gestures to support input with mouse and keyboard on large displays. In particular, we designed a gesture set for manipulating regular windows.

    Interaction techniques for wall-sized screens
    (2015) Lischke, Lars; Grüninger, Jürgen; Klouche, Khalil; Schmidt, Albrecht; Slusallek, Philipp; Jacucci, Giulio
    Large screen displays are part of many future visions, such as i-LAND that describes the possible workspace of the future. Research showed that wall-sized screens provide clear benefits for data exploration, collaboration and organizing work in office environments. With the increase of computational power and falling display prices wall-sized screens currently make the step out of research labs and specific settings into office environments and private life. Today, there is no standard set of interaction techniques for interacting with wall-sized displays and it is even unclear if a single mode of input is suitable for all potential applications. In this workshop, we will bring together researchers from academia and industry who work on large screens. Together, we will survey current research directions, review promising interaction techniques, and identify the underlying fundamental research challenges.
