Drivers have been proven to easily understand Augmented Reality (AR) information. Especially in an ambiguous navigation task, drivers are expected to benefit from AR information. The driving simulator study was aimed at examining differences in mental load while navigating in an urban area with ambiguous intersection situations (N = 59). The navigation information was presented to the driver through a head-up display (HUD): a conventional HUD or an AR display, which relates information to the surroundings. Additionally, the driver had to solve a non-driving-related task (NDRT) which was an auditory cognitive, spatial task. Results showed that while driving with the AR display, participants performed better in the NDRT, which indicates a reduced mental load compared with the HUD. Participants drove on average 3 km/h slower with the HUD, showing compensation behaviour.

事实证明，驾驶员可以轻松理解增强现实 (AR) 信息。特别是在模糊导航任务中，驾驶员有望从 AR 信息中受益。驾驶模拟器研究旨在检查在十字路口情况不明的市区（N = 59）中导航时心理负荷的差异。导航信息通过平视显示器 (HUD) 呈现给驾驶员：传统的 HUD 或 AR 显示器，将信息与周围环境相关联。此外，驾驶员必须解决与驾驶无关的任务 (NDRT)，这是一项听觉认知、空间任务。结果表明，在使用 AR 显示器驾驶时，参与者在 NDRT 中的表现更好，这表明与 HUD 相比，他们的心理负担减轻了。参与者在使用 HUD 的情况下平均行驶 3 公里/小时，
