Akustische Kodierung quantitativer Information in Karten — Ergebnisse einer Studie zum Vergleich mit klassischen Darstellungsformen

Acoustic Encoding of Quantitative Information in Maps — Results of a Study Comparing with Classical Forms of Representation

Zusammenfassung

Dieser Beitrag geht von der Kernhypothese aus, dass eine multikodale Darstellung durch Graphik und Klang eine umfangreichere und flexiblere Vermittlung von quantitativen Informationen sowie quantitativen Veränderungen in kartographischen Darstellungen ermöglicht. Zur Überprüfung dieser Hypothese wurden in einem ersten Schritt geeignete Klangvariablen zur Darstellung quantitativer Informationen analytisch selektiert. Als wichtigste Variable stellte sich die Tonhöhe heraus, die auch für die nachfolgende Konzeption und Implementierung von Klangkarten eingesetzt wurde. In einer Nutzerstudie wurden ausgewählte Aspekte der Gebrauchstauglichkeit (Usability) evaluiert und künftige Forschungsfragen abgeleitet.

Abstract

This contribution is based on the core hypothesis that a multicodal presentation through graphics and sound will enable a richer and more flexible provision of quantitative information and quantitative changes in cartographic displays. To test this hypothesis, in a first step, appropriate sound variables representing quantitative information have been selected analytically. The most important variable turned out to the pitch, which was used for the subsequent design and implementation of sound maps. In a follow-up user study, selected aspects of usability have been evaluated and future research questions have been deduced.
