Psychophysical scaling of sonification mappings

Abstract

We determined preferred data-to-display mappings by asking experiment participants directly and then examined the psychophysical scaling functions relating perceived data values to underlying acoustic parameters. Presently, we are extending and validating the scaled mappings in practical data interpretation tasks. The resulting scaling functions, in conjunction with the experimental paradigm developed here, should spark further research in this area and have implications for the design of future sonifications.
