Cognitive Support of Hazard Information by Using Sound Localization Based on the Wave Field Synthesis


Distraction due to thinking or reduction in arousal level makes a driver difficult to notice the surrounding hazard. Therefore, it is important to notify the surrounding hazard so that the driver can recognize it so quickly. This study is considering a system that informs a driver of spatial perception with the wave field synthesis to avoid traffic accident and the way to decrease effects of reflections to bring synthesized sound field to ideal sound field in a room of a car.本研究では,複数のスピーカによる波面合成法に基づく音像定位を用いて,運転者の情報認知を支援することで事故を未然に防ぐシステムを提案する.従来のスピーカによる方向提示システムと提案手法を比較検討する.また,実用化を目指した反射環境下における提案手法の有効性を明らかにする.
