Samenvatting
Generally drivers can perceive more information displayed by HUDs (Head-Up Displays) when the angle of depression is smaller. However, decreasing the angle in a practical automotive HUD where distance to the displayed image is short, sometimes causes misperception of displayed information in some experiments. This paper firstly describes how the angle of depression affects drivers' perceptions of a HUD image and the forward view. Then secondly we discuss why the misperception occurs, what it stems from, and what to do about it when designing HUDs, based on the experimental results derived from driver's eye movement analysis.
