车载音乐检索系统正变得越来越流行。以前的研究表明，当界面是触觉界面时，它们对司机构成真正的危险，这种界面需要多次输入，并结合手动控制和视觉反馈。语音接口作为一种选择而存在。这样的界面可能需要多次或单一的会话轮换。在这项研究中，17名年龄在18岁到30岁之间的参与者被要求在开车穿越虚拟世界时使用三种不同的音乐检索系统(一个带有多入口触摸界面，iPod(TM)，一个带有多转语音界面，接口B，以及一个带有单转语音界面，界面C)。记录次要任务绩效、眼球行为、车辆控制和工作量的测量。与触摸界面相比，语音界面减少了司机眼睛离开前方车道的总时间，特别是长时间的扫视，以及远离前方车道的总扫视次数和感觉到的工作量。此外，与没有辅助任务的驾驶相比，两种语音接口都不会对危险预期、远离前方道路的长时间注视的频率或车辆控制产生显著影响。多转弯语音接口(B)显著增加了司机完成任务所需的时间和工作量。讨论了对接口设计和安全性的影响。(C)2009爱思唯尔有限公司。保留所有权利。
In-vehicle music retrieval systems are becoming more and more popular. Previous studies have shown that they pose a real hazard to drivers when the interface is a tactile one which requires multiple entries and a combination of manual control and visual feedback. Voice interfaces exist as an alternative. Such interfaces can require either multiple or single conversational turns. In this study, each of 17 participants between the ages of 18 and 30 years old was asked to use three different music retrieval systems (one with a multiple entry touch interface, the iPod (TM), one with a multiple turn voice interface, interface B, and one with a single turn voice interface, interface C) while driving through a virtual world. Measures of secondary task performance, eye behavior, vehicle control, and workload were recorded. When compared with the touch interface, the voice interfaces reduced the total time drivers spent with their eyes off the forward roadway, especially in prolonged glances, as well as both the total number of glances away from the forward roadway and the perceived workload. Furthermore, when compared with driving without a secondary task, both voice interfaces did not significantly impact hazard anticipation, the frequency of long glances away from the forward roadway, or vehicle control. The multiple turn voice interface (B) significantly increased both the time it took drivers to complete the task and the workload. The implications for interface design and safety are discussed.
