Availability of Wave Transducer in Car Onboard System Interface

Abstract: The accident caused by the wrong treading of the pedal of the car becomes the social problem. The spread of advanced safety vehicles (ASV) is hurried as a passive safety in late years to reduce and prevent the damage of the accident. However, requiring a certain period of time for the spread of ASV and the valid situations are limited, and the problem such as not necessarily working appropriately is pointed out. On the other hand, it is thought that the information presentation system to let a driver recognize danger as the active safety is effective. In addition, the automatic operation system is in use to level 4 in Japan. A purpose of this study is to investigate the influence that shown information gives the cognitive function of the driver in the information presentation system of the onboard system. Therefore, the cognitive of the wave transducer interface implemented on the seat is confirmed by an experiment. For the experiment, we investigated the difference of the performance between the visual and the vibration interface using the simple driving simulator which embedded in both sides of the seat back. As a result, the difference was not seen between the visual and the vibration. In addition, by the subjective evaluation, the experiment participant felt that both stimulations were recognizable, and the difference was not seen. The experiment was suggested by a laboratory test as one of multi-modal interface by the transducer stimulation to be possible.
