      Mayer-Kress, Gottfried (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Perceptions of complex structures or other cognitive events are associated with synchronous oscillation of neural cell assemblies which take place in the 40 Hz domain and last for about 100 ms. We use EEG signals from 31 ...
    • An organization for high-level interactive control of sound 

      Das, Sumit; DeFanti, Tom; Sandin, Dan (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The state of computer generated sound has advanced rapidly, and there exist many different ways of conceptualizing the abstract sound structures that comprise music and other complex organizations of sound. Many of these ...
    • ADSL: An auditory domain specification language for program auralization 

      Bock, Dale S (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      ADSL (Auditory Domain Specification Language) is a program auralization specification language which encourages users to actively diagnose software bugs as opposed to just monitoring predetermined known program events. ...
    • Defining and redefining limits on human performance in auditory spatial displays 

      Shinn-Cunningham, Barbara; Durlach, Nathaniel (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Design of an effective auditory display depends upon understanding the requirements of the task as well as understanding limitations imposed by available display technology. However, an effective display also must consider ...
    • Auralization of document structure 

      Portigal, Steve; Carey, Tom (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      An experiment compared the effectiveness of auditory, visual, and combination cues to convey document structure. Subjects demonstrated an equivalent level of understanding of the document structure and its content with ...
    • A centralized audio presentation system 

      Papp III, Albert L; Blattner, Meera M (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The centralized audio presentation system addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Concurrent audio output can lead to perceptual ...
    • Designing with auditory icons 

      Mynatt, Elizabeth D. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Current research in auditory interfaces has produced a number of interesting interfaces without resulting in the compilation of design guidelines for creating descendent interfaces. This lack of a common design methodology ...
    • An evaluation of the communicative ability of auditory icons and earcons 

      Lucas, Paul A (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Audio cues are increasingly used to present information in the human-computer interface. To be of use, these cues must effectively communicate the intended information to the user. An evaluation of two types of nonspeech ...
    • Auditory direct manipulation of acoustical objects by blind computer users 

      Boelke, Ludger; Gorny, Peter (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
    • The 'GUIB' spatial auditory display - generation of an audio-based interface for blind computer users 

      Crispien, Kai; Petrie, Helen (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      In order to provide access to graphical-based user interfaces (GUI's) for blind computer users, a screen-reader program system is under development which conveys the GUI into auditive and/or tactile form. The spatial ...
    • Sound synthesis and composition applying time scaling to observing chaotic systems 

      Choi, Insook (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      This chapter presents a working model for bringing computational models to cognitive process by designing auditory signals for the models. Auditory structure is defined as an observed structure which is meaningful with ...
    • Perception of virtual auditory shapes 

      Hollander, Ari J.; Furness III, Thomas A. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Virtual environments may help us to understand and eventually extend the domain of auditory perception. The authors performed two experiments which verified the ability of subjects to recognize geometric shapes and ...
    • On the role of head-related transfer function spectral notches in the judgement of sound source elevation 

      Macpherson, Ewan A. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Using a simple model of sound source elevation judgment, an attempt was made to predict two aspects of listeners' localization behavior from measurements of the positions of the primary high-frequency notch in their ...
    • Sound localization in varying virtual acoustic environments 

      Zahorik, Pavel; Kistler, Doris J; Wightman, Frederic L (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      {Localization performance was examined in three types of headphone-presented virtual acoustic environments: an anechoic virtual environment, an echoic virtual environment, and an echoic virtual environment for which the ...
    • Out to lunch: Further adventures monitoring background activity 

      Cohen, Jonathan (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The sound of keystrokes and mouse clicks generated by a number of computer users gives coworkers a sense of "group awarenessn-a feeling that other people are nearby and an impression of how busy they are. L'OutToLunch," a ...
