Encoding and recognition heatmaps.

Encoding heatmaps are presented in the panels on the left side and recognition heatmaps in the panels on the right side. The top row shows the heatmaps of the eyes in world coordinates, the middle row the eyes in head-centered coordinates, and the bottom row the head positions in world coordinates. The coordinates of the heatmaps are all shown with longitudes in the range of −180° to 180° (from west to east) and latitudes in the range of −90° to 90° (from the south pole to the north pole). Note that for ease of comparison, the eyes in head-centered coordinates are shown with the same coordinates even though eyes in head coordinates are restricted to longitudes of about −70° to 70° (from west to east) and latitudes of about −60° to 60° (from south to north).
