Abstract
In this study, we investigated the effect of modality when providing videos during automated driving on the driver's takeover performance in the transition from automated driving to manual driving. In the basic experiment, participants were requested to perform video viewing task and visual detection task during automated driving. Significantly, the reaction time was about one second longer for pay more attention to video viewing than for pay more attention to outside. In the verification experiment, we evaluated the effect of interface modality of video viewing on participant’s performance when avoiding a collision with a front obstacle just after providing a takeover request (TOR). Significantly, TTC (Time to Collision) was shorter for video viewing without audio than for video viewing with audio.
