目的：研究两种车载信息系统（IVIS）对视觉、听觉和触觉信号检测的影响；确定IVIS对驾驶的有害影响是否可以通过这些检测任务来量化；并考察了刺激方式对信号检测的影响。背景：周边检测任务已被广泛用于评估IVIS对驾驶的影响。然而，这项任务的性能依赖于驾驶员看到一系列led的能力，这在现场测试（例如，在晴天）中可能会出现问题。方法：在模拟驾驶实验中，参与者对三个检测任务中的一个做出反应。还测量了IVIS相互作用对这些检测任务的影响。在检测任务中的表现下降被认为表明驾驶员在驾驶任务中处理突发事件的能力下降。结果：与基线驾驶相比，驾驶员执行IVIS任务时对所有检测任务的响应时间增加了约200 ms。方差分析和效应量比较表明，这两种ivis在三个检测任务中的效果是相同的。结论：这些检测任务有助于量化IVIS在驾驶过程中的安全性。不同的模态在信号检测上没有差异，这表明在这些任务中的表现依赖于一般的注意力资源，而不是特定于模态的。应用：这里使用的信号检测任务应进一步研究其在评估车载系统安全性方面的适用性。
Objective: This study examined the effect of two in-vehicle information systems (IVIS) on signal detection in the visual, auditory, and tactile modalities; established whether the detrimental effects of an IVIS on driving could be quantified by these detection tasks; and examined the effect of stimulus modality on signal detection. Background: The peripheral detection task has been used widely for assessing the effects of an IVIS on driving. However, performance on this task relies on drivers' ability to see a series of LEDs, which can be problematic in field tests (e.g., on sunny days). Method: Participants responded to one of three detection tasks during a simulated driving experiment. The effect of IVIS interaction on these detection tasks was also measured. Reduced performance in the detection tasks was assumed to indicate a decline in drivers' ability to handle sudden events in the driving task. Results: Response time to all detection tasks increased by around 200 ms when drivers performed the IVIS tasks, as compared with baseline driving. Analyses of variance and comparison of effect sizes showed the effects of these two IVISs to be the same across the three detection tasks. Conclusion: These detection tasks are useful for quantifying the safety of an IVIS during driving. The absence of a difference in signal detection by modality suggests that performance on these tasks relies on general attentional resources and is not modality specific. Application: The signal detection tasks employed here should be further investigated for their suitability in assessing the safety of in-vehicle systems.
