      Lemmens, Paul M.C; de Haan, Ab; van Galen, Gerard P (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      To investigate if location and content operate independently, two experiments were carried out in which redundant auditory co–messages to a visual categorization task were manipulated to enable left and right ear only ...
    • Effect of beacon sounds on navigation performance in a virtual reality environment 

      Walker, Bruce N.; Lindsay, Jeff (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Navigating without vision can be quite a daunting task. This study details an auditory interface to deal with this situation and then describes initial validation experiments. Ss were assigned to conditions with differing ...

      A navigation test was carried out in a spatially immersive virtual environment. The test was a game-like experience where task of subjects was to find as many gates as possible while they navigated through a track guided ...
    • Design process for auditory interfaces 

      Daude, Sylvain; Nigay, Laurence (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      In this paper we present a unified framework for the design of auditory interfaces. We describe the steps of the sonification process and their parameters. The process is modeled as a sequence of transformation functions ...
    • Interactive visualization and sonification for monitoring complex processes 

      Hermann, Thomas; Niehus, Christian; Ritter, Helge (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper introduces AVDisplay, a versatile auditory and visual display for monitoring, querying and accessing information about modules or processes in complex systems. In the context of a collaborative research effort ...
    • Evaluating soundscapes as a means of creating a sense of place 

      Turner, Phil; McGregor, Iain; Turner, Susan; Carroll, Fiona (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      We report an empirical study into the creation of, and response to, a soundscape of a computer centre. We contrast the use of presence questionnaires, as means of assessing the sense of being-there, against a more ...
    • Extracting significant features from the HRTF 

      Raykar, Vikas C; Duraiswami, Ramani; Davis, Larry; Yegnanarayana, B (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      The Head Related Transfer Function (HRTF) characterizes the auditory cues created by scattering of sound off a person's anatomy. While it is known that features in the HRTF can be associated with various phenomena, such ...
    • Household appliances control device for the elderly 

      England, David; Salces, Fausto J Sainz; Vickers, Paul (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      An evaluation of musical earcons was carried out to see whether they are an effective and efficient method of delivering information about household appliances to elderly people. A test was carried out to explore the ability ...
    • Identifying where you are in a room: Sensitivity to room acoustics 

      Shinn-Cunningham, Barbara; Ram, Suraj (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      In a spatial auditory display, reverberation provides a reliable cue for source distance, increases the subjective realism of the display, and improves the externalization of simulated sound sources. However, relatively ...
    • Instrument timbre models with noisy partial inclusion 

      O'Sullivan, Conor; Fernstrom, Mikael (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper presents the results of work performed in the area of analysis, manipulation and re-synthesis of musical instrument sounds. The goal is an efficient method of musical instrument sound modelling. Building on work ...
    • For those who died: A 9/11 tribute 

      Quinn, Marty; Quinn, Wendy; Hatcher, Ben (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      For Those Who Died is a 6-minute dance and music tribute to those who died on 9/11. It premiered 9/11/2002 as part of a larger event entitled ``Reflections, A Gift to the Community'' that occurred at the Music Hall in ...
    • Focalisation on the temporal context of complex sequences 

      Guillaume, Anne; Drake, Carolyn (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Studies of the perception of sound sequences indicate the existence of an optimal processing rate [1]: sequences in which sound events occur at rates within this range are processed in more depth than events within faster ...
    • Ocean buoy spectral data sonification: Research update 

      Sturm, Bob L (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
