Graphical desktops provide rich visual interaction for performing day-to-day computing tasks; the goal of the audio desktop is to enable similar efficiencies in an eyes-free environment. Thus, the primary goal of an audio desktop is to use the expressiveness of auditory output (both verbal and nonverbal) to enable the end user to perform a full range of computing tasks:

  • Communication through the full range of electronic messaging services

  • Ready access to local documents on the client and global documents on the Web

  • Ability to develop software effectively in an eyes-free environment

The Emacspeak audio desktop was motivated by the following insight: to provide effective auditory renderings of information, one needs to start from the actual information being presented, rather than a visual presentation of that information. This had earlier led me to develop AsTeR, Audio System For Technical Readings (http://emacspeak.sf.net/raman/aster/aster-toplevel.html). The primary motivation then was to apply the lessons learned in the context of aural documents to user interfaces—after all, the document is the interface.
