      Vargas, Maria L.M; Anderson, Sven (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Previous research on non-speech audio interfaces has demonstrated that they can enhance performance on menu navigation tasks. Most of this work has focused on tasks in which the menu is not spoken and visual representation ...
    • Communicating with sound: An ethological perspective 

      Fitch, W Tecumseh (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Due to the high density and importance of speech in most workplaces, practical sonification systems should be designed to complement and synergize with, rather than compete with, language. The multiple-message, high- ...
    • Comparison of auditory, visual, and audio-visual navigation in a 3D space 

      Grohn, Matti; Lokki, Tapio; Takala, Tapio (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      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 considerations for a background auditory display to aid pilot situation awareness 

      Kazem, Mandana L.N.; Noyes, Janet M; Lieven, Nicholas J (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Pilot Situational Awareness (SA), namely, the pilot's ability to accurately perceive, understand and predict events, is an essential requirement of effective decision-making [1]. Good `visibility' of aircraft state and ...
    • Design guidelines for audio representation of graphs and tables 

      Brown, Lorna M; Brewster, Stephen A; Ramloll, Ramesh; Burton, Mike; Riedel, Beate (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Audio can be used to make visualisations accessible to blind and visually impaired people. The MultiVis Project has carried out research into suitable methods for presenting graphs and tables to blind people through the ...
    • 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 ...
    • Discriminating visible speech tokens using multi-modality 

      Campbell, Christopher S; Shafae, Michael M; Lodha, Suresh K; Massaro, Dominic W (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      We present a multimodal interactive data exploration tool that facilitates discrimination between visible speech tokens. The multimodal tool uses visualization and sonification (non-speech sound) of data. Visible speech ...
    • Do location and context operate independently? 

      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 ...
    • Drawing by ear: Interpreting sonified line graphs 

      Brown, Lorna M; Brewster, Stephen A (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      The research presented here describes a pilot study into the interpretation of sonified line graphs containing two data series. The experiment aimed to discover the level of accuracy with which sighted people were able to ...
