Effects of guided arrows on head-up display towards the vehicle windshield

摘要

The concept of head-up display has gained wide acceptance being used for military aviation and has also spread to commercial aviation. Head up display (HUD) is now being used in automobiles to assist with navigation. The advantage of this system is reducing the number and duration of the driver's sight deviations from the road, by projecting graphic information on the windshield. Nevertheless, there has been little study as to how to use the super-imposed graphic such as guided arrows for car navigation system. The aim of the study is to evaluate the superimposition properties between the guided arrow marked on the road and the guided arrow on the center of the driver's field of vision, including the position of arrows. The subjects are assigned to carry out a car simulation test using an eye tracking device. The data was recorded in terms of eye movement and response time from both types of graphics in order to measure the driver's distraction. The results show that though the shape of the graphic has no effect, the location of the arrows does. The guide arrow also did not distract experienced drivers. This study can contribute a guideline for road safety.
