The prototype is based upon an auditory display schema which uses layers to organize different kinds of information. A user-input error beep. Zooming in and zooming out. Switching to the Galaxy visualization. The next four tracks demonstrate sounds the user might hear from the objects layer.
Auditory icons represent documents of differing size and media type.
The user is brushing their cursor over documents of various size and type. Clicking on a document point invokes a more detailed auditory icon. This one represents an average length text document. An audio document, followed by the sound of a longer audio document. A video document, followed by a short video document.
