A method of quantifying the effect of peripheral optical errors on patient locomotion includes projecting a pattern on the floor that includes a discrete shapes and empty spaces between the discrete shapes. The method also includes tracking a position of the participant along the pattern as the participant traverses the pattern, and determining foot placement accuracy, utilizing a optical motion capture system and a computer, as the participant walked through the pattern by determining a total area of overlap between the participant's feet and the empty spaces of the pattern. In another embodiment, the method includes arranging obstacles in front of a participant, intermittently displaying a character in front of the participant, determining participant's accuracy in identifying or counting the characters, and determining the participant's step length and foot clearance as the participant steps over the obstacles to quantify the effect of the peripheral optical errors on the participant's locomotion.
