Effects of Number of Layer in Automotive Display Menu Structure on Performance of Primary Driving and Secondary Task - Comparison between Young and Older Adults

摘要

The effects of age, display direction, arrangement of switches and number of layers on performance to the design of display and control systems were discussed. A dual-task experiment was conducted in which the primary task was first-order tracking. The secondary tasks included control of an air conditioner, the operation of a radio, and the operation of a CD/MD, by means of a steering wheel mounted switch. The display was arranged either in front of a participant. As predicted, age affected the performance measures. As for the young adults, the task completion time did not differ significantly among one-, two-, and three-layered conditions for both horizontal and vertical displays, and for both vertical and horizontal arrangements. The performance of older adults was affected by display condition, layer condition, and arrangement of switches. As for the completion time of secondary switch-pressing task, age by switch arrangement interaction, age by number of layers of display structure interaction, age by switch arrangement by number of layers interaction, and age by display direction by number of layers interaction were significant. Such results should be taken into account when designing display and control systems in man-vehicle systems.
