Two obstacles in the development of this framework will be insuring the analysts' ability to identify and discriminate between the cues, and validating the method for the selection of the audio cues. In the domain of satellite-ground control, these theories will be instantiated by adding an auditory environment to the existing visual environment. This auditory environment, assembled from qualitative audio cues, will be created for satellite-ground control analysts. The auditory environment will give the analysts information about the current state of the ground and spacecraft subsystems. One of the major issues is overcoming the identification and discrimination problem.
Identification is measured by one's ability to match a sound to an event in the world.
Discrimination is measured by one's ability to distinguish a single, specific sound when there are many perceivable sounds in the environment. Psychoacoustic literature will provide some information pertaining to the issues of identification and discrimination. Another issue is the validation of the method used to choose the audio cues placed in this environment. Visual interface design has a longer past. This research will assist in developing a language of audio cues which designers can use when designing auditory interfaces.
