固定型ドライビングシミュレータの運転席に発生させた運転支援のための振動パターンに関するアンケート調査

抄録

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. There is no room for further information regarding visual and auditory senses. However, it is considered that there is a margin for the tactile sense, since the sensory receptors 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. This report describes the results of a questionnaire survey on the impressions of four types of vibration patterns created for a driver assistance. Each pattern is generated in the driving seat of a fixed-type driving simulator while simulating a driving scenario assumed. The results showed that the activity factor, represented by the sense of urgency, was large because simulating the scenario.
