Whither and wherefore the auditory graph? Abstractions & aesthetics in auditory and sonified graphsh
A good deal of attention has been paid by the auditory display community to the sonification of graphical data and the term au- ditory graph has been used to describe this class of auditory map- pings. We contend that definitions have become blurred leading to first-order sonifications of functions and data being treated as synonymous with the second- and higher-order mappings obtained when graphs of those functions and data are themselves sonified. This paper looks at the different types of sonifications currently known collectively as auditory graphs and, based on this analysis, proposes a purposeful distinction to be drawn between auditory graphs and sonified graphs. An example is taken from the domain of computer programming to further illustrate the argument.
