Advances in mirror technology have motivated the need for revisiting the question of how drivers use their mirrors while driving. Blind spots are the common complaint of mirrors, and new designs have appeared in the U.S. and European markets to help improve overall visibility. This research involves the study of how drivers perform and accept various combinations of left and right outside planar, convex, and aspheric mirrors. In addition, this research expands the basic design to examine the effect of increasing the vertical dimension of mirrors. This paper reports the work in progress, including the most recent research issues and activities completed just prior to data analysis.
