Designing browsing for in-car music player

subject

description

User interface features of a touch based mobile music player and their comparative impact on driver distraction when searching music albums were investigated. In a driving simulator experiment (N=18) three scrolling methods buttons, swipe and kinetic were compared, whereat the number of music tracks presented in a list-style format varied between three, five and seven items per page. Half of the participants used the music player in a portrait mode and half of them in a landscape mode. It was expected that swipe supports less severe distraction effects than kinetic or button due to systematic page-by-page scrolling and low levels of pointing accuracy required for browsing. Three items should enable more efficient visual sampling efficiency per page, but visual demands are increased compared to five or seven since more scrolling is required. Screen orientation should have no distraction effects. Results indicate that swipe led to less severe distraction effects than buttons or kinetic scrolling methods. Seven items per page was found most distracting, whereas few significant differences were found between three and five. As predicted, screen orientation had no significant effects.
