Abstract Driving task requires cognitive processes to sense traffic environment, understand context and situation, and decide how to control vehicle. This cognitive workload is mainly caused by processing visual information acquired while driving. This visual cognitive workload is one of the key factors for driving safety with visual distraction. To reduce these visual workload and distraction, augmented reality technology is applied to head-up display (AR-HUD). However, AR-HUD can confuse driver by overlaying graphical object onto real traffic object, degrade driver performance, and as a result increase risk of accidence. To confirm whether the AR-HUD is useful enhancing driving safety or not, we conducted experiments on driver’s cognitive response behavior under daytime and nighttime conditions. In this paper, we describe the AR-HUD system we have been developing and experiments and results. Keywords Augmented reality

1 Introduction Motor vehicle accidents result usually from a complex interaction between the driver, vehicle and environmental factors. Analyses of traffic accidents indicate that human factors are a sole or a contributory factor in approximately 90 % of road traffic accidents [1, 2]. Driving task requires cognitive processes to sense traffic environment, understand context and situation, and decide how to control vehicle. This cognitive workload is mainly caused by processing visual information acquired while driving.

This visual cognitive workload is one of the key factors for driving safety with visual distraction. To decrease drivers’ visual distraction head-up display (HUD) technology has been developed and launched in a lot of commercial vehicles. It was reported that the usage of HUD reduces drivers’ distractions and improves driving safety, and is estimated to contribute lower vehicle crashes up to 25 % [3]. And the drivers had a faster response and they were more consistently controlled speed when using a HUD compared with a head-down display (HDD) [4]. To reduce visual cognitive workload in addition to visual distraction, augmented reality technology is applied to head-up display (AR-HUD). The augmented reality can enhance the traffic situation awareness of road vehicles, pedestrians, obstacles, and route [5]. One study proposed AR-HUD system providing all of the detected vehicles and pedestrians information to drivers through a transparent display installed in front of the driver, fitting to the drivers’ view [6]. We developed AR-HUD system and conducted experiments on driver’s cognitive response behavior under daytime and nighttime conditions to confirm whether the AR-HUD i
