使用音频输出的车载设备已被证明比传统的图形用户界面更少分散注意力，但使用起来可能很麻烦且缓慢。在本文中，我们报告了一个实验，演示了这些性能特征如何影响人们是否会选择在多任务处理情况下使用音频接口。在驾驶模拟车辆时，参与者必须在一小段文字中找到信息来源。文本要么在视觉界面上呈现，要么使用文本到语音的音频界面。每项任务的相对重要性各不相同。一个没有选择/选择的范例中使用的参与者首先获得的经验与两个接口，然后被给予一个选择的接口上使用以后的试验。在无选择阶段测量的接口，和每个任务的相对重要性的相互作用的特点，有影响的输出方式选择在选择阶段。优先考虑次要任务的参与者倾向于选择（更快但更分散注意力的）视觉界面而不是音频界面，因此车道保持性能较差。这项工作演示了用户的任务目标将如何影响多模态设备在多任务环境中的模态选择。
In-car devices that use audio output have been shown to be less distracting than traditional graphical user interfaces, but can be cumbersome and slow to use. In this paper, we report an experiment that demonstrates how these performance characteristics impact whether people will elect to use an audio interface in a multitasking situation. While steering a simulated vehicle, participants had to locate a source of information in a short passage of text. The text was presented either on a visual interface, or using a text-to-speech audio interface. The relative importance of each task was varied. A no-choice/choice paradigm was used in which participants first gained experience with each of the two interfaces, before being given a choice on which interface to use on later trials. The characteristics of the interaction with the interfaces, as measured in the no-choice phase, and the relative importance of each task, had an impact on which output modality was chosen in the choice phase. Participants that prioritized the secondary task tended to select the (faster yet more distracting) visual interface over the audio interface, and as a result had poorer lane keeping performance. This work demonstrates how a user's task objective will influence modality choices with multimodal devices in multitask environments.
