Multi-touch interactions for model-based sonification
MetadataShow full item record
This paper presents novel interaction modes for Model-Based Soni- fication (MBS) via a multi-touch interface. We first lay out details about the constructed multi-touch surface. This is followed by a description of the Data Sonogram Sonification Model and how it is implemented using the system. Modifications from the original sonification model such as the limited space scans are described and discussed with sonification examples. Videos showing exam- ples of interaction are provided for various data sets. Beyond Data Sonograms, the presented system provides a basis for the imple- mentation of known and novel sonification models. We discuss the available interaction modes with multi-touch surfaces and how these interactions can be profitably used to control spatial and non- spatial sonification models.
