Schematic representation of the simulated visual field defects (VFD) used in this study. From left to right: central loss (scotoma size: 10°), peripheral loss (scotoma size: whole screen except for a 10° hole), hemifield loss (right half of the screen). During the experiment, the VFD was applied in a gaze-contingent manner: the center of the VFD is matched in real-time with the point of gaze of the participant, with a latency below 4 ms. This latency roughly corresponds to the inter-frame interval and ensures proper gaze-contingency.
