Vertical (elevation) pointing angles for six example targets during eyes-open (EOC). The mobile pointing application reproduces similar pointing angles across participants for each target. Left: a schematic of what the angles on the polar histograms represent. 90 degrees would be straight up and 0 is straight ahead. Middle: the polar histograms without averaging for all trials and all participants for six example targets that cover the entire vertical range of targets. Right: images of two example targets with numbers matching the numbers on the histograms and in Figs. 2, 4, and 5. Black arrows show the target participants were asked to point to
