最近的研究表明，呈现运动信号(例如，身体表面隐约可见的或明显的运动)的听觉和振动触觉向前碰撞警告可以加快制动反应时间(BRT)。本研究的目的是通过直接比较在所有碰撞事件中传递的运动是恒定的警告信号与运动速度取决于闭合速度(CV)的信号来扩展这项工作。使用模拟跟车任务进行了两个实验，并测量了BRT。在实验1中，驾驶员腰部的单个触摸器发出了强度增加(隐约可见)的振动触觉信号。当强度的增加与CV相关时，BRT显著快于无警告条件，然而，它们与恒定强度和CV无关的隐约警告没有显著差异。在实验2中，三个手柄的垂直排列被用来产生朝向(向上)或远离(向下)驾驶员头部的运动。当警告信号呈现向上运动且与CV相关时，BRT显著快于所有其他警告类型。与向上移动的警告相比，向下移动的警告导致在错误警报情况下的刹车激活次数显著增加。因此，动态触觉碰撞警告的有效性似乎既取决于警告和碰撞事件之间的联系，也取决于警告信号的方向性。
Recent research demonstrates that auditory and vibrotactile forward collision warnings presenting a motion signal (e.g., looming or apparent motion across the body surface) can facilitate speeded braking reaction times (BRTs). The purpose of the present study was to expand on this work by directly comparing warning signals in which the motion conveyed was constant across all collision events with signals in which the speed of motion was dependent on the closing velocity (CV). Two experiments were conducted using a simulated car-following task and BRTs were measured. In Experiment 1, increasing intensity (looming) vibrotactile signals were presented from a single tactor attached to the driver's waist. When the increase in intensity was CV-linked, BRTs were significantly faster as compared to a no-warning condition, however, they were not significantly different from constant intensity and CV-independent looming warnings. In Experiment 2, a vertical array of three tactors was used to create motion either towards (upwards) or away (downwards) from the driver's head. When the warning signal presented upwards motion that was CV-linked, BRTs were significantly faster than all other warning types. Downwards warnings led to a significantly higher number of brake activations in false alarm situations as compared to upwards moving warnings. The effectiveness of dynamic tactile collision warnings would therefore appear to depend on both the link between the warning and collision event and on the directionality of the warning signal.
