- Abstract
- Das vorliegende Buch befaßt sich mit der theoretischen Begründung, Gestaltung und empirischen Bewertung eines Datenbankzugangs durch graphisches Retrieval. Der Autor stellt das Informationssystem Wing-Graph vor, das am Beispiel Werkstoffdaten die Veränderung von Liniendiagrammen durch graphische Aktionen in der benutzeroberfläche zur Recherche nach numerischer Information erlaubt. Darunter ist eine graphische Recherchesprache zu verstehen, mit der man visuelles Denken direkt für die Suche nutzen kann. Der Autor entwickelt auf der Basis kognitionspsychologischer Erkenntnisse über Wahrnehmung und Interpretation von Informationsgraphiken ein Modell des graphischen Retrieval, in dem 3 wichtige Aspekte der Interaktion mit graphischer Information vereinigt sind: die visuelle Vorstellungsfähigkeit, der Handlungsaspekt der Mensch-Maschine-Interaktion und die Systemfunktionalität einer graphischen Datenbankschnittstelle. Im Vergleich mit traditionellen Abfragesprachen stehen in Wing-Graph einfache, aber leistungsfähige graphische Operationen zur Verfügung, die das visuelle Denken des Benutzers operationalisieren. Die Generalisierbarkeit des Ansatzes für andere Domänen wird untersucht und in exemplarischer Weise an Wirtschaftsdaten überprüft

- Abstract
- Der 'Ort ohne Raum' ist eine Galerie im WWW, die versucht, die Nutzungsstruktur des WWW mit meist (hyper-)textueller Information zu interaktiven Anwendungen zu erweitern, in die der Anwender selbst eingreifen kann. Das Ziel ist nicht eine einfach Reproduktion des Konzeptes einer Galerie in einem anderen Medium, sondern die Spezifik des Mediums soll den Betrachter zu grundsätzlich anderen und erweiterten Interaktions-, Manipulations- und Navigationsmöglichkeiten führen. Der 'Ort ohne Raum' entsteht seit 1995 als Kooperationsprojekt zwischen den Fachbereichen Medienkunst der Hochschule für Grafik und Buchkunst in Leipzig und der Abteilung für Automatische Sprachverarbeitung am Institut für Informatik der Universität Leipzig
