Hidden details of negotiation: the mechanics of reality-based collaboration in information seeking

Social activities such as collaborative work and group negotiation can be an essential part of information seeking processes. However, they are not sufficiently supported by todays information systems as they focus on individual users working with PCs. Reality-based UIs with their increased emphasis on social, tangible, and surface computing have the potential to tackle this problem. By blending characteristics of real-world interaction and social qualities with the advantages of virtual computer systems, they inherently change the possibilities for collaboration, but until now this phenomenon has not been explored sufficiently. Therefore, this paper presents an experimental user study that aims at clarifying the impact such reality-based UIs and its characteristics have on collaborative information seeking processes. Two different UIs have been developed for the purpose of this study. One is based on an interactive multi-touch tabletop in combination with on-screen tangibles, therefore qualifying as a reality-based UI, while the other interface uses three synchronized PCs each controlled by keyboard and mouse. A comparative user study with 75 participants in groups of three was carried out to observe fundamental information seeking tasks for co-located collaboration. The study shows essential differences of emerging group behavior, especially in terms of role perception and seeking strategies depending on the two different UIs.

ScatterTouch: a multi touch rubber sheet scatter plot visualization for co-located data exploration

Mathias Heilig; Stephan Huber; Mischa Demarmels; Harald Reiterer

This paper introduces a touch-sensitive two-dimensional scatter plot visualization, to explore and analyze movie data. The design focuses on the ability to work co-located with several users. These are able to create several focus regions through distortion techniques triggered by multi touch gestures. Furthermore, the introduced visualization is an example how promising concepts from InfoVis research can be transferred onto multi touch tables in order to offer more natural interaction.

Die Blended Library : Benutzerorientierte Verschmelzung von virtuellen und realen Bibliotheksdiensten

Mathias Heilig; Roman Rädle; Harald Reiterer

In diesem Beitrag wird die Idee der „Blended Library“ vorgestellt, welche die Entwicklung von neuen Konzepten fur die Unterstutzung des Rechercheprozesses in der physischen Bibliothek der Zukunft beschreibt. Im Zuge der voranschreitenden Digitalisierung wurden in der Vergangenheit in den unterschiedlichsten Bereichen versucht, reale Dienste der Bibliothek auf digitale Dienste zu ubertragen. Jedoch gingen dadurch viele soziale und physische Mehrwerte realer Umgebungen (z. B. personlicher Kundenkontakt, raumliche Orientierung, greifbare Medienobjekte) verloren. Dieser Beitrag schlagt deshalb einen Paradigmenwechsel vor – weg von der Entwicklung rein virtueller Welten, hin zur Einbettung von Informationstechnologien in die soziale und physische Welt einer Bibliothek. In der Blended Library werden Benutzern somit vollig neue Formen der Recherche und der Wissensvermittlung geboten. Dies soll durch den umfassenden Einsatz von neuen interaktiven Endgeraten und zukunftsweisenden Visualisierungen geschehen und somit reale und virtuelle Angebote bzw. Funktionen der Bibliothek zusammenfuhren. Eine Fallstudie dient dabei als erste exemplarische Umsetzung einer Blended Library, welche umfassend auf den kreativen Arbeitsablauf eines Wissensarbeiters in der Bibliothek der Zukunft eingeht. Das Konzept wird anhand eines realitatsnahen Szenarios vorgestellt, in dem die Designentscheidungen der Fallstudie basierend auf „Conceptual Blending“ erklart werden.
