This research focuses on the relationship between the spatial self-position-detection with landmarks and the function of the visual field. 28 college students participated in the experiment were asked to move the center of the landmarks in virtual environment. By measuring the difference between the stopped positions under each condition and the exact central point of landmarks, the accuracy of the spatial position detection was quantified. The results indicate that the central visual field within 5 degrees and the visual field of 15 to 20 degrees of vision centered on the fixation point play a large role in the self-position-detection.
