Abstract

The occurrence of accidents caused by deficiencies in risk recognition by the driver can be prevented by presenting relevant information in real time to the driver. In this paper it is proposed to draw the driver's attention towards relevant traffic objects, which might be a safety hazard, by a LED strip which is affixed 360° around the interior of the car's cabin. With this approach a higher number of use cases can be covered than with existing HMIs. The effectiveness of this system is evaluated in a driving simulator study with 13 subjects in four critical traffic situations. The gaze attention times are ascertained with eye tracking technology; mental effort and acceptance are determined by questionnaires and the comprehensibility by semi-structured interviews. There are indications of shortened gaze attention times using the LED strip compared to the baseline without driver support. The subjects understand the information submitted mostly intuitively. The acceptance ratings overall are in a positive range, but differ between scenarios.

驾驶员辅助通过光学信息与空间参考

通过实时向驾驶员提供相关信息，可以防止驾驶员因风险认知不足而导致事故的发生。本文提出通过在汽车舱室内部360°贴一条LED灯条，将驾驶员的注意力吸引到可能存在安全隐患的相关交通物体上。与现有的hmi相比，使用这种方法可以覆盖更多的用例。在四种关键交通情况下，13名受试者进行了驾驶模拟器研究，评估了该系统的有效性。利用眼动追踪技术确定注视注意时间;心理努力和接受度由问卷决定，可理解性由半结构化访谈决定。有迹象表明，与没有驱动程序支持的基线相比，使用LED灯会缩短凝视注意力的时间。被试对提交的信息大多是凭直觉理解的。总的来说，接受度在一个积极的范围内，但不同的场景有所不同。
