为了评估动态振动触觉碰撞警告信号在潜在增强安全驾驶方面的有效性，进行了四项实验。听觉神经科学研究表明，靠近人的听觉信号比远离人的听觉信号更显着。如果发现这种迫在眉睫的效果延伸到触觉方式，那么它可以用于车内警告信号设计。使用模拟跟车任务评估各种振动触觉警告信号的有效性。振动触觉警告信号包括动态朝向/远离躯干线索（实验 1）、动态与静态振动触觉线索（实验 2）、迫近强度和恒定强度朝向躯干线索（实验 3）以及手部或腰部呈现的静态线索，具有低或高振动强度（实验 4）。与远离躯干提示（实验 1 和 2）和静态提示（实验 2）相比，朝向躯干的制动反应时间 (BRT) 明显更快。这种差异不能归因于对传递到不同身体部位的信号的不同反应（即腰部与手部；实验 4）。将迫在眉睫的强度信号嵌入到躯干信号中并没有带来任何额外的 BRT 好处（实验 3）。感觉好像正在接近躯干的动态振动触觉提示可用于传达有关外部事件的信息，从而显着加快对潜在碰撞的反应时间。向身体移动的动态振动触觉警告信号为未来车内碰撞警告系统的设计提供了巨大的潜力。
Four experiments were conducted in order to assess the effectiveness of dynamic vibrotactile collision-warning signals in potentially enhancing safe driving. Auditory neuroscience research has demonstrated that auditory signals that move toward a person are more salient than those that move away. If this looming effect were found to extend to the tactile modality, then it could be utilized in the context of in-car warning signal design. The effectiveness of various vibrotactile warning signals was assessed using a simulated car-following task. The vibrotactile warning signals consisted of dynamic toward-/away-from-torso cues (Experiment 1), dynamic versus static vibrotactile cues (Experiment 2), looming-intensity- and constant-intensity-toward-torso cues (Experiment 3), and static cues presented on the hands or on the waist, having either a low or high vibration intensity (Experiment 4). Braking reaction times (BRTs) were significantly faster for toward-torso as compared to away-from-torso cues (Experiments 1 and 2) and static cues (Experiment 2). This difference could not have been attributed to differential responses to signals delivered to different body parts (i.e., the waist vs. hands; Experiment 4). Embedding a looming-intensity signal into the toward-torso signal did not result in any additional BRT benefits (Experiment 3). Dynamic vibrotactile cues that feel as though they are approaching the torso can be used to communicate information concerning external events, resulting in a significantly faster reaction time to potential collisions. Dynamic vibrotactile warning signals that move toward the body offer great potential for the design of future in-car collision-warning system.
