ABSTRACT
This study aims to provide practical and comprehensive guidelines for designing the haptic (or vibrotactile) interface in vehicles. Twenty participants took part in the experiments that were conducted at driving simulation environments. This study recommended the proper intensity (approximately, 26~34Hz and 2.0~3.4G), position (seat pan or back support), direction (horizontal or indirect), and intervibration distance (8~9cm), and showed how the characteristics of drivers, such as gender and age, had effects on setting the design variables of the haptic interface in the vehicle seat.
