    Prototype Auditory Displays for a Fuel Efficiency Driver Interface
    (Georgia Institute of Technology, 2014-06) Nees, Michael A. ; Gable, Thomas M. ; Jeon, Myounghoon ; Walker, Bruce N.
    We describe work-in-progress prototypes of auditory displays for fuel efficiency driver interfaces (FEDIs). Although research has established that feedback from FEDIs can have a positive impact on driver behaviors associated with fuel economy, the impact of FEDIs on driver distraction has not been established. Visual displays may be problematic for providing this feedback; it is precisely during fuel-consuming behaviors that drivers should not divert attention away from the driving task. Auditory displays offer a viable alternative to visual displays for communicating information about fuel economy to the driver without introducing visual distraction.

    Science or art? “Sonification in the age of biocybernetics reproduction”: A case study of the Accessible Aquarium Project
    (Georgia Institute of Technology, 2013-07) Jeon, Myounghoon ; Walker, Bruce N. ; Bruce, Carrie M.
    With digital art being pervasive, art, technology, and science seem to be no longer separable and have been re-integrated. In fact, art history shows that when combined with them, art could give birth to a ground-breaking masterpiece. Based on that, we pose a simple question, “Can we analyze sonification works from the viewpoint of digital art aesthetics?” As a case study, we try to place the Accessible Aquarium Project (AAP) at the intersection of scientific research and art. Relying on term, “biocybernetics”, we discuss aesthetic meanings of the AAP in terms of new temporality (dynamicity), transformed relationships (combined gazes), dialectic improvement of the original (interactivity), and enacted collective art-work (embodied cognition). We hope this review will help illuminate the artistic contribution of interactive sonification and explore future directions. Further, this work is expected to contribute to facilitating discussions of aesthetics about the sonification works in the auditory display community.

    Aquarium fugue: interactive sonification for children and visually impaired audience in informal learning environments
    (Georgia Institute of Technology, 2012-06) Jeon, Myounghoon ; Winton, Riley J. ; Yim, Jung-Bin ; Bruce, Carrie M. ; Walker, Bruce N.
    In response to the need for more accessible Informal Learning Environments (ILEs), the Georgia Tech Accessible Aquarium Project has been studying sonification for the use in live exhibit interpretation in aquariums. The present work attempts to add more interactivity [1] to the project’s existing sonification work, which is expected to lead to more accessible learning opportunities for visitors, particularly people with vision impairments as well as children. In this interactive sonification phase, visitors can actively experience an exhibit by using tangible objects to mimic the movement of animals. Sonifications corresponding to the moving tangible objects can be paired with real-time interpretive sonifications produced by the existing Accessible Aquarium system to generate a cooperative fugue. Here, we describe the system configuration, pilot test results, and future works. Implications are discussed in terms of embodied interaction and interactive learning.

    Reducing Repetitive Development Tasks in Auditory Menu Displays with the Auditory Menu Library
    (Georgia Institute of Technology, 2010-06) Raman, Parameswaran Raman ; Davison, Benjamin K. ; Jeon, Myounghoon ; Walker, Bruce N.
    This paper explores the process of auditory menus research. Several parts are tedious tasks which must be repeated for minor changes to the experiment. Fortunately many of these parts can be automated with software. We present the Auditory Menu Library (AML), a tool for simplifying experiment construction. The AML provides a cross-platform, configuration-based turnkey solution to studies involving auditory menus.
