Driving simulator study of driver behavior while using head-up display

We developed head-up display (HUD) in the AIST driving simulator. The information on the HUD is displayed on the front screen using an additional projector that is mounted on the roof of the vehicle cabin. The projection range covers the entire windshield. We evaluated driver's acceptance of the HUD that is presented around a location of a leading vehicle. The findings indicate that drivers paid more attention to the information overlapping the lead vehicle. The attentional workload was improved by the information location and information contents.
