Im Beitrag wird ein ganzheitliches Visualisierungs- und Interaktionskonzept für die Überwachung und Diagnose eines großen Straßennetzes sowie die Manipulation von Prozessvariablen im Kontext einer Verkehrsleitzentrale vorgestellt. Um das kooperative Arbeiten zu unterstützen wird das Konzept einer Multi-Focus-View in Kombination mit einer inhaltssensitiven Navigation verfolgt. Ziel ist es, die Navigation im Straßennetz, die Verfügbarkeit kontextsensitiver Informationen sowie die Manipulation von Prozessvariablen in Verkehrsleitzentralen zu verbessern. Weiterhin werden Ergebnisse einer Evaluation mit Anwendern aus Verkehrsleitzentralen vorgestellt, in der insbesondere die Auswirkungen unterschiedlicher Konzepte auf das Arbeiten in einer Mehrbenutzerumgebung untersucht wurden.

In this paper we report a comparative study investigating two interaction techniques for grouping items spatially on a tabletop interface. We compared a container technique with a proximity technique. The container concept was considered due to its familiarity with desktop systems, while the proximity technique is a novel organic concept based on spatial proximity. Our goal was to identify the characteristics of both techniques in regard to grouping and regrouping performance, grouping strategies as well as bimanual and multi-finger input. Our results indicate that the traditional container concept may not be an adequate fit for harnessing the benefits of interactive surfaces. Rather, our study shows that more informal spatial techniques based on proximity open up a promising design space for further investigations

Proxemics in Human-Computer Interaction (HCI) offer new prospects for the design of explicit and implicit interaction techniques to support multiple users and a concurrent navigation for zoomable user interfaces (ZUI). In this paper we describe a navigation concept for zooming and panning based on a multi-display environment using proxemic relations as input (e.g. a user’s location and orientation in physical space to manipulate a viewport). We hope to foster awareness of the topic and to inspire further discussion and research on proxemics in HCI.

This demo presents two interaction techniques for grouping items spatially on a tabletop interface. It allows participants of the conference to experience and compare the container technique “Bin“ and the proximity technique “Blub“. While the container concept is similar to the folder concept on desktop systems, the proximity technique is a novel organic concept based on spatial proximity. Within an associated paper submitted to the main conference track, we studied the characteristics of both techniques in regard to grouping and regrouping performance, grouping strategies and use of multi-finger input. Our study showed that more informal spatial techniques based on proximity are able to harness more benefits of direct-touch multi-finger and bimanual interaction. In our demo, participants will be able to compete in grouping items with both techniques.

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 users’ ability to master a system than we typically believe – especially for spatial panning or zooming & panning user interfaces. We conducted two experiments to observe whether multi-touch instead of mouse input improves users’ spatial memory and navigation performance for such UIs. We observed increased performances for panning UIs but not for zooming & panning UIs. We present our results, provide initial explanations and discuss opportunities and pitfalls for interaction designers.

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, thereby increasing awareness over inhibitors that may impede the success of such sessions. The general applicability of our approach was confirmed in a user study with creative professionals. We conclude that live design activity visualizations can provide benefits for controlling typical inhibitors of creative group work without the need to change traditional workflows.

Context-sensitive information is of vital importance to the Monitoring of processes in control rooms, but its incorporation in current state-of-the-art user interfaces is inadequate. By looking at a traffic control center as an example, this paper proposes an interaction concept for monitoring complex networks on large remote displays. Our approach is based on content-aware navigation with the goal to improve the navigation of the road network and the availability of context-sensitive information. We conducted a study comparing different navigation techniques as well as two techniques for visualizing context-sensitive information.

This demo presents TwisterSearch, a system for co-located and collaborative Web search that was designed in accordance with the canonical model of social search by Evans and Chi (2009). In a first phase before search, participants frame the context of the intended search and thereafter gather initial information requirements on a tabletop. These requirements are then refined through discussion and yield the foundation for the search task itself, which is performed in parallel on multiple mobile displays. These private devices are used to search the Web for evidence files and to populate the visual workspace of the tabletop with them. Moreover, the personal device allows both a highly parallel search as well as a tightly-coupled collaborative search, to enable seamless switching between collective and solitary search activities. In our TwisterSearch demo, participants can have a firsthand experience of these different individual phases of social search.

This paper describes the perspective+detail visualization concept, which extends the conventional overview+detail pattern by adding a perspective viewing area and a further, text-based area containing partial details. Known problems of such extensions are mitigated using a vertically curved display. Our concept aims to bridge both the geographical and the content gap between the two main display areas and to provide an improved overview. An experimental case study based on a typical traffic control room operator task provided first insights on our visualization. These initial findings revealed that perspective+detail assists users in fulfilling their tasks and keeping their orientation in the information space.

The ever-growing amount of digitized books and electronically published documents necessitates proper tools to search and explore such large digital information spaces. This paper presents the design of an interactive prototype for collaborative visual information seeking (VIS) in an on-line book repository. The main objectives of the prototype are a visual metaphor to query an on-line book repository and the facilitation of back-and-forth comparison of search results. Furthermore, an integrated cosine similarity search encourages for serendipitous discoveries while browsing through an information space.

In this paper we report from a case study investigating the use of digital tools for documenting collaborative design processes. We employed the note-taking system Evernote in interaction design projects with six teams of students over a period of four months. By observing the use and appropriation of the tool and by questioning participants we strived toward understanding collaborative ocumentation and communication activities in more detail. Our experiences show that the core unctionality of such tools seems adequate for most documentation tasks, but improvements seem necessary regarding support for more informal information management, visualization as well as communication and collaboration.

Libraries are well known as work places and thus have a common way of everyday use. Unfortunately, there is a gap between the physical and digital contents of a library and its media. By expanding the physical, tangible media with digital information, many new possibilities for interaction would open up for users. With the help of a prototype, we want to show how it is possible to shrink this gap with the use of blends and augmented reality. The Augmented Shelf allows for an overlay of digital information and additional functionality over a certain inventory in real time depending on the position of the user in a three dimensional space. The users are able to highlight physical artifacts, leave virtual commentaries and search for related media.

In this paper we describe an experimental study investigating the use of bimanual and multi-finger input for grouping items spatially on a tabletop interface. In a singleuser setup, we compared two typical interaction techniques supporting this task. We studied the grouping and regrouping performance in general and the use of bimanual and multi-finger input in particular. Our results show that the traditional container concept may not be an adequate fit for interactive tabletops. Rather, we demonstrate that informal and organic spatial metaphors are able to harness more benefits of multi-finger and bimanual interaction. We conclude with recommendations for the design of grouping techniques on interactive surfaces.

This paper addresses the lack of interaction qualities in control rooms by investigating the potential use of Hybrid Surfaces. As an emerging trend with strong real-world references, they offer the combination of both, the qualities of physical interaction and the potentials of the digital world. To determine their applicability in the given context we applied the theoretical framework ‘Reality-Based Interaction’ in line with an expert focus group. As the primal finding tangible forms have aroused great interest as they embody the feature to express ongoing processes states and allow multimodal interaction.

Interactive spaces are ubiquitous computing environments for computer-supported collaboration that exploit and enhance the existing cognitive, physical and social skills of users or groups of users. The workshop aims at documenting and advancing the current state-of-the-art of co-located collaboration in interactive spaces and identifying research challenges and formulating a research agenda by inviting high-quality position and research papers from HCI, Information Visualization, CSCW and CSCL.

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 their physical environment. To thoughtfully blend the power of the digital world with the users’ pre-existing skills and practices, we propose and explain conceptual blending as a potential design methodology. We illustrate our framework by discussing related theoretical and conceptual work and by explaining the design decisions we made in recent projects. In particular, we highlight how Blended Interaction introduces a new and more accurate description of users’ cognition and interaction in interactive spaces that can serve as a tool for HCI researchers and interaction designers.

Although Web search is typically regarded as a solitary activity, collaborative search approaches are becoming an increasingly relevant topic for HCI and distributed user interfaces (DUIs). Today’s collaborative search systems lack comprehensive search support that also involves pre- or post-search activities such as preparation or sensemaking. We believe that post-WIMP DUIs can help to better support social search and have identified four design goals that are critical for their successful design. In consequence, we present TwisterSearch, an interactive DUI prototype that meets our four design goals.

In this paper we describe a novel approach for supporting co-located collaborative sketching sessions. Our system is based on digital pen & paper and an interactive visualization that can be used by a session facilitator for examining live design activity. We argue that such visualizations may provide benefits for improving creative group work without the need to change traditional practices.

In this paper, we address the problem of designing for participation and parallel interaction with a large-scaled tabletop system. Beginning with a short description of our tabletop-integrated multi-user tracking system we introduce Dynamic Personal Spaces (DPS), which are virtual representations of a user’s workspace on a table. Furthermore we provide a number of applications that can be implemented based on the tracking system and DPSs. This collection shall serve as a starting point for people implementing applications that are based on the DPS approach.
