Three experiments were conducted to assess the effectiveness of dynamic vibrotactile warning signals with different spatial patterns and to compare dynamic towards-torso and towards-head vibrotactile warnings in a simulated driving task. The results revealed that embedding additional stimuli between the participant's hands and waist in the towards-torso cues (Experiment 1) and increasing the spatial distance between adjacent stimuli in the towards-head cues (Experiment 2) did not result in any further benefits in braking response times (BRTs). The triple towards-head cues resulting from the sequential operation of three pairs of stimuli on the torso gave rise to a significant advantage over the static cues; however, it did not outperform the dynamic towards-torso cues with just two pairs of stimuli. Taken together, these results demonstrated the promise of dynamic vibrotactile warnings (especially, the towards-torso warnings) in terms of the future design of more effective rear-end collision warnings.

进行了三项实验，以评估具有不同空间模式的动态振动触觉警告信号的有效性，并在模拟驾驶任务中比较朝向躯干和朝向头部的动态振动触觉警告。结果显示，在朝向躯干的提示中（实验1），在参与者的手部和腰部之间嵌入额外刺激，以及在朝向头部的提示中（实验2）增加相邻刺激之间的空间距离，在制动反应时间（BRT）方面并未带来任何进一步的益处。由躯干上三对刺激顺序操作产生的三重朝向头部的提示比静态提示具有显著优势；然而，它并未超过仅两对刺激的动态朝向躯干提示。综合来看，这些结果证明了动态振动触觉警告（特别是朝向躯干的警告）在未来设计更有效的追尾碰撞警告方面的前景。
