    • LSL: A specification language for program auralization 

      Mathur, Aditya P.; Boardman, David B.; Khandelwal, Vivek (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The need for specification of sound patterns to be played during program execution arises in contexts where program auralization is useful. We present a language named LSL (Listen Speciikation Language) designed for ...
    • The varcese system, and satellite-ground control: Using auditory icons and sonification in a complex, supervisory control system

      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 ...
    • 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 ...
    • 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. ...
    • 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 ...
    • 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. ...
    • A perceptual framework for the auditory display of scientific data 

      Barrass, Stephen (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      A principal requirement of the auditory display of scientsc data is an accurate portrayal of the information contained in the data. The characteristics of the display device can significantly affect the faithfulness of the ...
    • Integrating speech and nonspeech sounds in interfaces for blind users 

      Pitt, Ian (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Synthetic speech is widely used by blind people to enable them to receive textual output from computer systems. Used appropriately, speech provides a reasonably high level of access to command-line systems such as DOS and ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Using audio windows to analyze music 

      Cohen, Michael (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Alternative nonimmersive perspectives enable new paradigms of perception, especially in the context of frames-of-reference for musical audition and groupware. "maw," acronymic for multidimensional audio windows, is an ...
