Engaging with mobile music retrieval

Abstract

This paper contributes novel measures of user engagement in mobile music retrieval, linking these to work in music psychology, and illustrating resulting design guidelines in a demonstrator system. The large music collections available to users today can be overwhelming in mobile settings, they offer ‘too-much-choice’ to users, who often resort to shufflebased playback. Work in music psychology has introduced the concept of music engagement – listeners vary in their desired control over their music listening, and engagement varies with listening context. We develop a series of metrics to capture music listening behaviour from users’ interaction logs. In a survey of 94 music listeners, we show significant correlations between music engagement from questionnaires and the presented quantitative metrics. We show how music retrieval can adapt to this engagement, developing a tabletbased demonstrator system, with an exploratory evaluation.
