چکیده انگلیسی
The distance of first-fixation to vertical road signs was assessed in 22 participants while driving a route of 8.34â¯km. Fixations to road signs were recorded by a mobile eye-movement-tracking device synchronized to GPS and kinematic data. The route included 75 road signs. First-fixation distance and fixation duration distributions were positively skewed. Median distance of first-fixation was 51â¯m. Median fixation duration was 137â¯ms with a modal value of 66â¯ms. First-fixation distance was linearly related to speed and fixation duration. Road signs were gazed at a much closer distance than their visibility distance. In a second study a staircase procedure was used to test the presentation-time threshold that lead to a 75% accuracy in road sign identification. The threshold was 35â¯ms, showing that short fixations to a road signs could lead to a correct identification.
