This study was designed to investigate the possibility that driver responses to potential front-to-rear-end collision situations could be facilitated by implementing vibrotactile warning signals that indicate the likely direction of the potential collision. In a car following scenario in a driving simulator, participants drove along a rural road while trying to maintain a safe headway distance to the lead car using a visual distance display. Participants had to respond as quickly as possible to the sudden deceleration of the lead car which had its brake lights disabled, either with or without vibrotactile cues (presented in different experimental blocks). The results demonstrated significantly faster braking responses and larger safety margins when the vibrotactile warning signal was presented than when it was not. These findings demonstrate the effectiveness of vibrotactile cues in helping drivers to orient their spatial attention in the appropriate direction. Our results add to a growing body of empirical evidence highlighting the potential benefits of using "intuitive" vibrotactile in-car displays, in this case, to alert drivers to potential collisions and to provide time-critical directional information.
本研究旨在探讨通过实施振动触觉警告信号来促进驾驶员对潜在的前后碰撞情况做出反应的可能性，该信号指示潜在碰撞的可能方向。在驾驶模拟器中的跟车场景中，参与者沿着乡村道路行驶，同时使用视觉距离显示器试图与前车保持安全的车距。参与者必须尽快对刹车灯失灵的前车突然减速做出反应，实验分为有或没有振动触觉提示（在不同的实验块中呈现）两种情况。结果表明，与不呈现振动触觉提示时相比，呈现振动触觉警告信号时的制动反应明显更快，安全裕度更大。这些发现证明了振动触觉提示在帮助驾驶员将空间注意力导向适当方向方面的有效性。我们的研究结果进一步补充了越来越多的实证证据，突出了使用“直观的”车内振动触觉显示器的潜在好处，在这种情况下，是为了提醒驾驶员潜在的碰撞并提供时间紧迫的方向信息。
