    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Task-oriented quantitative testing for synthesized 3-D auditory displays 

      Julig, Louise Frantzen; Kaiwi, Jerry L. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Current human machine interfaces in Navy systems which incorporate headphone listening fail to take full advantage of human binaural sensory processing capabilities. These interfaces can be improved by providing the ...
    • System for psychometric testing of auditory representations of scientific data 

      Smith, Stuart; Levkowitz, Haim; Pickett, Ronald M.; Torpey, Mark (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      This chapter describes a computing environment with which an investigator can interactively design and test an auditory data display. We describe the components of our system and how they are used, and we give some preliminary ...
    • 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 ...
    • The run-time components of sonnett 

      Jameson, David H (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Sonnet is an audio-enhanced monitoring and debugging system whose aim is to investigate how sound can be used in a program development environment. Running under AIX, it consists of a visual programming language to design ...
    • Using virtual environment technology to present a digital sound library 

      Whitehead, John F (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Digital sound libraries of today can be difficult to navigate. For example, sampling keyboards often display only the currently selected sound, and it is not easy to know the adjacent sounds or how to find desired ones. ...
    • Using additive sound synthesis to analyze simplicial complexes 

      Axen, Ulrike; Choi, Insook (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      We present a new technique for traversing simplicia1 complexes and producing sounds from the output of this traversal. The traversal algorithm was invented in order to extract temporal information from static geometric ...
    • Voice annotation of visual representations in computer-mediated collaborative learning 

      Steeples, Christine (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      New computer-based communications technologies-such as electronic conferencing, electronic mail, communal hypertext, and communal hypermedia databases-make it possible for people to collaborate in their learning, even when ...
    • The varcese system, and satellite-ground control: Using auditory icons and sonification in a complex, supervisory control system 

      Albers, Michael C (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
    • 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 ...
