As machines become more complex, it becomes more difficult for human beings to monitor the condition of the machine by only observing it from outside or listening to the operation sound. In order to prevent serious accidents, it is necessary that the machine informs the condition to human beings instantaneously, and that human beings respond appropriately. That is, the human-machine interface is important. For example, when human beings drive a car, visual, auditory, olfactory and tactile senses are used. For the visual sense, it is used for grasping the map information displayed on the car navigation system in addition to grasping the road and traffic conditions, so there is no margin for it. For the auditory sense, it is used for listening to music to relax in addition to grasping the road and vehicle conditions, so there is no margin for it. For the olfactory sense, it is used for grasping the vehicle condition by an unusual odor. For the tactile sense, it is used for grasping the road condition and vehicle motion. It is considered that there is a margin for it, since the sensory receptors for the tactile sense are widely distributed. Then, we have been proposed that vibration stimulus using a chair with a built-in vibration generator applying speaker technology are used to inform a driver about the risks. In this study, impressions on five simple vibrations were confirmed by factor analysis as basic data for designing vibrations suited to the situation.
