Abstract: This study focuses on how to design a visual-auditory presentation to minimise the interference in information processing between modality channels; and to improve the effectiveness of mental integration of multimodal information. A method was proposed to convert textual information describing sequential relationships into a |graphics + voice| presentation. It was hypothesised that this dual-modal presentation would result in superior comprehension performance and user satisfaction as compared with the pure textual display. Findings of our experiment fully supported the hypothesis and would benefit interface design of mobile applications by alleviating the overabundance of information output in the visual channel.
Keywords: human attention; information presentation; multimodal interfaces; mobile learning; m-learning; working memory; sequential relationships; information processing; mental integration; visual-auditory presentation; voice; graphics; comprehension performance; user satisfaction; interface design.
