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

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.
