The authors have conducted mainly indoor experiments in which they tested the legibility of three place names in Tokyo area displayed by a navigation device by having the observers read the place names as quickly and accurately as possible. The three place names simulate a road sign at an intersection. The reading time and the reading accuracy of the three place names are examined under various experimental conditions, such as the size of the displayed place name, the position of the display device, the observer's age and other factors. For example, to reproduce experimental conditions, three kinds of display devices and display positions are tested; first, head-up display in the central vision, second, head-up display in the peripheral (near central) vision, and third, the conventional LCD display in the peripheral vision. There are thirty observers in three age ranges (in their 20s, 40s, and 60s), with ten in each group. The authors have revealed how the experimental conditions affect the legibility of the three place names displayed by in-vehicle navigation devices.
