Listening to Pictures

If you're blind, how do you see art? How do you see graphs, or
graphics, tables of information, or web pages? The simple answer is, by
sound. By understanding the 'thing' we can describe it, by turning the
properties of the thing into sounds we can hear it, by using a computer
and keyboard we can interact with it. Here, we'll take a tour around
auditory display, experiencing audification and sonification. I'll
explain the whys and hows and discuss how auditory display has the
potential to enhance everyone's lives.<br>
