We present results from a study of truck drivers’ experience of using two different interfaces; spoken interaction and visual-manual interaction, to perform secondary tasks while driving. The instruments used to measure their experience are based on three popular questionnaires, measuring different aspects of usability and cognitive load: SASSI, SUS and DALI. Our results show that the speech interface is preferred both regarding usability and cognitive demand.
