Identifying and evaluating conceptual representations for auditory-enhanced interactive physics simulations

摘要

Interactive simulations are tools that can help students understand and learn about complex relationships. While most simulations are primarily visual due to mostly historical reasons, sounds can be used to add to the experience. In this work, we evaluated sets of audio designs for two different, but contextually- and visually-similar simulations. We identified key aspects of the audio representations and the simulation content which needed to be evaluated, and compared designs across two simulations to understand which auditory designs could generalize to other simulations. To compare the designs and explore how audio affected a user's experience, we measured preference (through usability, user experience, and open-ended questions) and interpretation accuracy for different aspects of the simulation (including the main relationships and control feedback). We suggest important characteristics to represent through audio for future simulations, provide sound design suggestions, and address how overlap between visual and audio representations can support learning opportunities.
