運転者状態と環境情報を利用する道案内：人による道案内と カーナビゲーションシステムによる道案内の比較から

抄録

In car navigation systems, route guidance messages which can be understood with less cognitive load and without any visual information are required. We study effective guidance methods using a comparison between human guidance and current navigation systems. Experimental results show that the guidance messages including visible landmarks are useful for drivers' understanding. Also, the messages should be provided at the appropriate timing for drivers' understanding of the route and driving behaviors. Based on these results, we pursue guidance systems using environmental objects and driver's status monitoring devices.
