      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. ...

    • Auralization of document structure 

      Portigal, Steve; Carey, Tom (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)

    • 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 ...
    • 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 ...
    • Design and evaluation of an auditory glance at algebra for blind readers 

      Stevens, R.D; Brewster, S.A; Wright, P.C; Edwards, A.D.N (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      An overview or glance is important in planning the reading process. Such a high-level view is not possible for a blind person when reading by listening. This paper describes the sonification of algebra notation to provide ...
    • 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 ...
    • Dynamical resonances and synchronization of auditory stimuli and evoked reponses in multi-channel EEG 

      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 ...
    • Effect of event variations and sound duration on identification of everyday sound 

      Ballas, James A (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Experimental data on sound perception are presented on two issues: what aspects of a complex sound with several transients are important for accurate identification, and how much of a sound must be heard to identify it. ...
    • Efficient listening with two ears: Dichotic time compression and spatialization 

      Arons, Barry (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      To increase the amount of information we can collect in a given amount of time, it is possible to employ signal processing techniques to speed up the rate at which recorded sounds are presented to the ears. Besides simply ...
    • Efficient modeling of the head-related transfer functions 

      Lueck, Charles (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Efficient representations of the head-related transfer functions (HRTFs) based on autoregressive moving average (ARMA) modeling are explored in this chapter. A relatively new technique for ARMA order estimation, based on ...
    • 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 ...
    • Factors in the design of effective auditory displays 

      Watson, Charles S; Kidd, Gary R (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The design of effective auditory displays requires an understanding of both capabilities and response proclivities. This disti ctionis explained in relation to a variety of auditory tasks and a range of acoustic stimuli. ...
    • GUI admission for VIPs: A sound initiative 

      Poll, L.H.D; Eggen, J.H. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Until now, mostly character-based applications were used on office computers. These applications could be accessed by visually impaired persons(VIPs) using Braille or synthetic speech. Recently, there has been a shift ...
    • 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 ...
    • The importance of head movements for localizing virtual auditory display objects 

      Wightman, Frederic L; Kistler, Doris J (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      In most of our research we produce virtual sound sources by filtering stimuli with head-related transfer functions (HRTF's) measured from discrete source positions and present the stimuli to listeners via headphones. With ...
