Using Augmented Reality for Full-Windshield Displays and Crash Avoidance

美国每年大约有3万人死于机动车事故。事故的发生往往是因为驾驶员不能及时看到危险，特别是当危险被遮挡时（在前车前面刹车的车辆，闯红灯的车辆等）。目前，这种技术相当昂贵，导致采用率较低。事实上，汽车增强现实领域正在寻找一种具有广泛吸引力和深远影响的“应用”。避免崩溃可以是这样一个应用程序，它使更多的用户对采用这种硬件感兴趣，然后为开发和采用其他应用程序提供基础。目前正在进行研究，以确定如何使用增强现实（AR）作为大视场平视显示器来显示警告。概念包括显示驱动程序应该看哪里的箭头和突出显示驱动程序应该看什么的图形。实现需要一个全挡风玻璃平视显示器（HUD）来显示图形，连接车辆的通信技术，以及经过验证的用户界面概念。这些元素将结合在一个产品中，一个可以大大减少机动车碰撞的产品。该团队已经在驾驶模拟器中开发并测试了增强现实界面的概念验证原型。该界面包含一些突出显示危险的方法，例如下划线或周围框。然而，当危险不在司机面前或看不见时，他们面前会出现一个箭头，指示他们向左或向右看。

Each year approximately 30,000 people are killed in the U.S. in motor vehicle crashes. Often crashes occur because the driver cannot see the hazard in time, especially when the hazard is obscured (a braking vehicle in front of the lead vehicle, a crossing vehicle running a red light, etc.). Currently such technology is quite expensive, which has led to lower levels of adoption. Indeed, the field of augmented reality for cars is looking for an 'application' that will have broad basis of appeal and deep impact. Crash avoidance could be such an application that gets more users interested in adopting this hardware, which then provides the basis for other applications to be developed and adopted.Research is being conducted to determine how Augmented Reality (AR), implemented as a large field of view head-up display, can be used to present warnings. Concepts include arrows showing where drivers should look and graphics to highlight at what drivers should look. Implementation requires a full-windshield Head-Up-Display (HUD) to show the graphics, communications technology to connect vehicles, and validated user interface concepts. These elements are to be combined in a product, one that could substantially reduce motor vehicle crashes. The team has developed and tested a proof-of-concept prototype of the augmented reality interface in a driving simulator. That interface consists of some means to highlight a hazard, such as an underline or a surrounding box. However, when the hazard in not in front of the driver or not visible, an arrow appears in front of them directing them where to look, either to the left or right.
