Average 2D-pointing-variability as a function of target eccentricity and visual field.

<p>Pointing variability is depicted separately for pointing movements performed with the left hand (left panel) and movements performed with the right hand (right panel). Grey lines represent movements executed in the free-viewing conditions and black lines represent movements executed in the fixation conditions. The performance of the control participants is represented as dashed lines and DF's performance as solid lines. Error bars depict the sample standard deviation.
