目的：进行驾驶模拟器研究，以评估单模态听觉、单模态振动触觉和组合听觉触觉（即多感官）车内警告信号的相对效用，以在模拟现实驾驶的情况下向驾驶员发出可能的前后碰撞事件的警报和通知。背景：非视觉车内警告信号的实施可能对减少驾驶过程中的视觉过载具有重要的安全意义。多感官整合可以提供协同促进效应。方法：参与者在有或没有广播节目的背景下，在跟车场景中沿着乡村道路行驶。在反复试验的基础上，领头车辆的刹车灯信号也无法预测地启用或禁用。结果：结果表明，与呈现单模态听觉或单模态振动触觉警告信号相比，参与者在呈现听觉触觉警告信号后明显更快地启动制动反应。结论：多感官警告信号提供了一种在驾驶等要求较高的情况下吸引驾驶员注意力的特别有效的方法。应用：参考最近的认知神经科学研究解释了这种多感官车内警告信号的潜在价值。
Objective: A driving simulator study was conducted in order to assess the relative utility of unimodal auditory, unimodal vibrotactile, and combined audiotactile (i.e., multisensory) in-car warning signals to alert and inform drivers of likely front-to-rear-end collision events in a situation modeled on real-world driving. Background: The implementation of nonvisual in-car warning signals may have important safety implications in lessening any visual overload during driving. Multisensory integration can provide synergistic facilitation effects. Method: The participants drove along a rural road in a car-following scenario in either the presence or absence of a radio program in the background. The brake light signals of the lead vehicle were also unpredictably either enabled or disabled on a trial-by-trial basis. Results: The results showed that the participants initiated their braking responses significantly more rapidly following the presentation of audiotactile warning signals than following the presentation of either unimodal auditory or unimodal vibrotactile warning signals. Conclusion: Multisensory warning signals offer a particularly effective means of capturing driver attention in demanding situations such as driving. Application: The potential value of such multisensory in-car warning signals is explained with reference to recent cognitive neuroscience research.
