Effect of Width and Separation in Rear Window Defroster Lines on the211 Indentification of Obstacles

摘要

A static, indoor study was conducted to assess the effects of rear window211u001edefroster/defogger line width and separation on the identification of obstacles 211u001elocated to the rear of a motor vehicle. Additional independent variables included 211u001eparticipant age, rake angle of the rear window, and target location in the 211u001erearward field of view. The targets used in this simulated backing/reversing 211u001etask, as seen through the interior rearview mirror, were a trash can (low 211u001econtrast) and a child's bicycle (high contrast). The dependent variables were 211u001ereaction time to correctly identify the target, and subjective ratings of how 211u001eeasily targets could be seen through the simulated defroster/defogger line 211u001epatterns.
