Interface design is an important factor in assessing the potential effects on safety of interacting with an in-vehicle information system while driving. In the current study, the layout of information on a visual display was manipulated to explore its effect on driving performance in the context of music selection. The comparative effects of an auditory-verbal (cognitive) task were also explored. The driving performance of 30 participants was assessed under both baseline and dual task conditions using the Lane Change Test. Concurrent completion of the music selection task with driving resulted in significant impairment to lateral driving performance (mean lane deviation and percentage of correct lane changes) relative to the baseline, and significantly greater mean lane deviation relative to the combined driving and the cognitive task condition. The magnitude of these effects on driving performance was independent of layout concept, although significant differences in subjective workload estimates and performance on the music selection task across layout concepts highlights that potential uncertainty regarding design use as conveyed through layout concept could be disadvantageous. The implications of these results for interface design and safety are discussed.
界面设计是评估与车载信息系统交互时对安全产生潜在影响的一个重要因素。在本研究中，通过操纵视觉显示上的信息布局来探索其在音乐选择情境下对驾驶表现的影响。还探索了听觉-言语（认知）任务的比较效果。使用变道测试，在基线和双重任务条件下评估了 30 名参与者的驾驶表现。与基线相比，同时进行音乐选择任务和驾驶会显著降低横向驾驶表现（平均车道偏离和正确变道的百分比），与组合驾驶和认知任务条件相比，平均车道偏离显著增加。这些对驾驶性能的影响的程度与布局概念无关，尽管布局概念之间的主观工作量估计和音乐选择任务的绩效存在显著差异，这表明设计使用的潜在不确定性（通过布局概念传达）可能是不利的。讨论了这些结果对界面设计和安全的意义。
