The design and formative evaluation of nonspeech auditory feedback for an information system

Abstract

This research describes a user-centered design method for creating nonspeech auditory feedback to enhance information interactions with a visual information system. It involves 2 studies. In the first, a user-centered sound design method is used, based on one originally applied for visually impaired users. Three panels of end users are employed to collaboratively and iteratively design the required nonspeech sounds. The method ensures that the sounds designed are not based on designers' personal or ad hoc choices and instead exploits the creativity of a user group as an application of participatory sound design. Based on the results of this study, recommendations are made for extending the sound design method to novel interfaces and sighted users. A second study involves a formative evaluation of the information system integrated with the designed auditory feedback. This evaluation confirms that the user-centered sound design method leads to the creation of auditory feedback which conveys meaningful information to users.

Rhythms of Everyday Life in Mobile Information Seeking: Reflections on a Photo-Diary Study

“…This cognitive, information-processing model of information seeking has largely underpinned information retrieval system design and information-behavior models. Today, voice, audio, and haptic technologies have become mainstream 1 (e.g., Apple's Siri or Amazon's Alexa), and there is increased recognition that digital interactions are not confined to text-based resources (e.g., Absar and Guastavino 2015) or one physical space. People move across physical and virtual spaces in their work and leisure activities aided by ubiquitous digital technologies, including smartphones.…”
