Use of a Remote Eye-Tracker for the Analysis of Gaze during Treadmill Walking and Visual Stimuli Exposition

Figure 1

A schematic representation of the experimental setup, which included a screen (1), a rET (2), a treadmill (3), and a stereophotogrammetric system (4). Three retroreflective markers were placed on the subject’s head to track its movements. The inclination of the rET with respect to the horizontal plane () and its distance from the projecting surface () were, respectively, set to 18 deg and 690 mm. The head reference frame and the rET reference frame are reported.
