Different gaze areas used for analysis of gaze locations.

<p>Five black dots indicate the starting position (SP), the target (T), the hand target (HT), the inverted target (IT), and the cursor (C) positions. The HT position is the hand location that would bring the cursor to the target under the rotated visual feedback (example shown for the 75° rotation). The IT position is the 180° inverted location of the target. The starting position (SP) area, the cursor (C) area, and the target vicinity have a circular shape. The mid area is an area between the SP and target vicinity. The hand-target (HT) area and the inverted-target (IT) area have the same shape as the combined area of the target vicinity and the mid area.
