Vertical (top row) and sagittal (bottom row) directional errors for the 6 targets for the three groups: healthy (blue circles), stroke-mild (red) and stroke-moderate-to-severe (black). Subjects viewed the VE through the head mounted display (light blue squares) and screen projection system (orange circles). Data are mean values in each group. Targets: UC - upper contralateral, UM - upper middle, UI - upper ipsilateral, LC - lower contralateral, LM - lower middle, LI - lower ipsilateral.
