抄録

Although originally developed for aircraft use, head-up displays (HUDs) have recently found application in automobiles.<BR>Studies of HUDs in aircraft shows that HUDs are superior to head-down displays in terms of aircraft operation and that this superiority stems from reducing pilot eye accommodation and eye movement.<BR>Focusing on the driver's peripheral vision, we have done two kinds of experiments to examine what makes automotive HUDs superior. One examines how the recognizability of HUD images declines when peripheral vision is not available ; the other evaluates how much displayed image information can be obtained through peripheral vision.<BR>We have concluded that peripheral vision plays an important role in recognizing of HUD images presented at a small depression angle and a long distance. The contribution by peripheral vision to the recognition of displayed images can be of equal importance to that of reduction of eye accommodation and eye movement.
